     TECHNICAL FIELD 
     The present invention relates to a resin composition for a sheet, and more particularly to an eco-friendly poly(alkylene carbonate) resin composition containing a poly(alkylene carbonate) resin capable of efficiently utilizing carbon dioxide, which is a major contributor to global warming, as a main material, and containing three or more kinds selected from the group consisting of an strength controller, a flexibilizer, a dimensional stabilizer, an impact modifier, a filler, a obliterating power improver, a foaming agent, a foaming cell control agent, a flame retardant, an flameproofing agent, an antifogging agent, and a lubricant. 
     BACKGROUND 
     A polyvinyl chloride material used in housing of human or office spaces has been requested or restricted such that a polyvinyl chloride resin is not used for toys for children, food packing, bags for Ringer in hospitals, or the like, by the Ministry of Environment and the authorities concerned, due to environmental pollution and harmfulness to the human body, inside or outside the country. Furthermore, the use thereof has been steadily restricted abroad, particularly in Europe, such as, regulating import and export customs clearance of products containing the polyvinyl chloride resin. The main reason is that products made of polyvinyl chloride materials are difficult to recycle, and thus are incinerated as waste, thereby generating a large amount of harmful gases such as hydrogen chloride (HCl), and dioxin, which are fatal to the human body. 
     Specifically, since the polyvinyl chloride material is alone not made into products fundamentally, processing additives, such as plasticizers, stabilizers, flame retardants, dyes, and the like, are used in order to solver the above problems, and these materials incur the harmful gases and dioxin. Among the processing additives, a phthalatebased plasticizer used in order to impart workability and flexibility to the polyvinyl chloride is an environmental hormone, and thus has a fatal effect on the human and natural ecosystem. Therefore, four plasticizer maker companies made an agreement in respect to restricting the use of polyvinyl chloride in the country. Stabilizers and dyes have been determined to be very fatal to the human body and natural ecosystem since they contain heavy metals that are fatal to the human body, and thus, the use thereof is restricted. 
     Alternatives using eco-friendly common plastics have been developed in order to solve problems of these polyvinyl chloride products. However, the alternatives have problems related to physical properties; for example, they can be easily broken in the winder time due to deficiency in flexibility. Furthermore, processing additives need to be additively used since they are poor in printability, cut-ability, and adhesive property thereof, and thus, incur an increase in costs. Moreover, economic feasibility is lowered due to production by extrusion processing and high price of materials themselves. 
     SUMMARY 
     An embodiment of the present invention is directed to providing an object of overcoming deterioration in post processability, such as printability, cut-ability, adhesive property, or the like, and deterioration in physical properties of products made of modified polyethylenes, which are eco-friendly common plastics, such as polypropylene, polyethylene terephthalate, polyurethane, thermoplastic olefin based resin, acrylic resin, and the like, as alternatives of polyvinyl chlorides, by using a poly(alkylene carbonate) resin as a main material and adding a minimal processing additives not harmful to the human body and natural ecosystem. 
     An embodiment of the present invention is directed to providing an object of allowing products made of a poly(alkylene carbonate) resin composition according to the present invention to have excellent a flameproofing property and improved smoke density, thereby preventing a large amount of fatal and harmful gases, which are unfavorable as an interior material, from being generated at the time of a fire. 
     An embodiment of the present invention is directed to providing an object of overcoming a weakness that a pellet type polymer material is difficult in calender processing and thereby to remarkably lower production costs as compared with extrusion processing, performing a process at lower temperature than a polyvinyl chloride resin and thereby improve the workability, and lowering specific gravity and thereby reduce the manufacturing costs of production companies. 
     In one general aspect, a resin composition for a sheet includes: 0.1 to 100 parts by weight of an strength controller, 0.1 to 50 parts by weight of a flexibilizer, 0.1 to 30 parts by weight of a obliterating power improver, 0.1 to 200 parts by weight of a filler, and 0.1 to 5 parts by weight of a lubricant, based on 100 parts by weight of a poly(alkylene carbonate) resin. 
     The resin composition for a sheet may further include 0.1 to 5 parts by weight of a compatibilizer based on 100 parts by weight of the poly(alkylene carbonate) resin. 
     The resin composition for a sheet may further include 0.1 to 30 parts by weight of an impact modifier based on 100 parts by weight of the poly(alkylene carbonate) resin. 
     The resin composition for a sheet may further include 0.5 to 20 parts by weight of a foaming agent or 0.1 to 200 parts by weight of a flame retardant based on 100 parts by weight of the poly(alkylene carbonate) resin. 
     The resin composition for a sheet according to the present invention necessarily includes the additives having the above content ranges together with the poly(alkylene carbonate) resin, thereby improving post processability, such as mechanical property, processability, printability, cut-ability, adhesive property, or the like, or anti-flame property, and allows calender processing, resulting in remarkably lowering production cost as compared with extrusion processing, thereby improving economic feasibility. 
     The strength controller is a polymer resin having a high glass transition temperature, which is added in order to improve mechanical property (tensile strength, tear strength, or the like) of plastics having a low glass transition temperature (Tg), and functions to additively improve heat-resistant property and dimensional stability of products besides the mechanical property. The strength controller may include a polyolefin based resin such as polyethylene and polypropylene, an ethylene vinyl acetate resin, a polymethylmethacrylate resin, polylactic acid, or a biodegradable resin of modified polyester resins, and be any one or more selected from linear low density polyethylene, random polypropylene, polymethylmethacrylate, polylactic acid, and ethylene vinyl acetate. The flexibilizer may be any one or more selected from acrylate based compounds and glutaric acid compounds. 
     The strength controller is in a pellet type or a liquid type, and a modified polyester or thermoplastic copolyester elastomer having a number average molecular weight of 200 to 500 may be used as the strength controller. 
     The strength controller is contained in 0.1 to 100 parts by weight based on 100 parts by weight of the poly(alkylene carbonate) resin. If the concentration of the strength controller deviates from the above range, a synergy effect in improvement of physical property due to combination with other components is decreased, and thus, improvement in the heat resistant property or dimensional stability of the products can not be expected, and physical properties such as tensile strength, tear strength and the like, are deteriorated. 
     In addition, in a case where the polyolefin based resin is used as the strength controller, the compatibilizer may be used. The compatibilizer can function to obtain a blend having a uniform compositional ratio and perform an important role in improvement of physical properties, by improving fusion or melting with polyolefin. 
     As the compatibilizer, a polyethylene based type including polyethylene and maleic anhydride, a polypropylene based type including polypropylene and maleic anhydride, an ethylene vinyl acetate type including ethylene vinyl acetate, polystyrene, and maleic anhydride, or a linear low density polyethylene type including linear low density polyethylene and maleic anhydride. Here, the linear low density polyethylene based compounds may have a melt index (190° C., ASTM D1238) of 0.3 to 0.9 g/10 min and a density of 0.5˜2.0 g/cm 3 . 
     The compatibilizer may be included in 0.1 to 5 parts by weight based on 100 parts by weight of the poly(alkylene carbonate) resin, thereby improving physical properties such as tensile strength, tear strength, elongation, and the like, processability, dimensional stability, and cold resistant property through combination with other components. 
     The filler may be an inorganic filler including calcium carbonate, talc, white clay, titanium dioxide, magnesium carbonate, barium carbonate, aluminum hydroxide, calcium hydroxide, magnesium hydroxide, zinc oxide, white carbon, or amorphous silica, or an organic filler including a melamine resin or an urea resin. 
     The filler is contained in 0.1 to 200 parts by weight based on 100 parts by weight of the poly(alkylene carbonate) resin. If the concentration of the filler deviates from the above range, a synergy effect due to combination with other components may be decreased, and there may be deterioration in rigidity of products and shrinkage and deformation of the products. 
     The lubricant is added to plastics during processing and finely coated on surfaces of the plastics, and thereby to reduce friction between polymer processing apparatuses and between polymer-polymer. As a result, the lubricant increases productivity of products, and prevents adhesion between plastics to facilitate the use of sheet or film typed products. The lubricant may be used for improving the heat resistant property of the final product, and preventing respective sheets from being adhered to each other at the time of winding the final product. The lubricant may be stearic acid or dioctyl terephthalate. 
     The lubricant is contained in 0.1 to 5 parts by weight based on 100 parts by weight of the poly(alkylene carbonate) resin. If the concentration of the lubricant deviates from the above range, a melt viscosity is too low such that processability deteriorates, and thus, improvement in physical properties can not be expected through combination with other components. 
     Examples of the impact modifier may include any one or more selected from methylmethacrylate-butadiene-styrene (MBS) copolymer which is poor in heat resistant property, chemical resistant property, and weather resistant property but excellent in impact strength, acrylic based Impact modifier (AIM) which is lower than a butadiene type impact modifier in impact strength but excellent in heat resistant property and chemical resistant property, or chlorinated polyethylene (CPE) which is favorable in view of costs than physical properties. Here, as for the impact modifier for use in opacity, an apparent specific gravity is 0.25 g/cc or more, and grains not passing through #10 mesh are contained in 3 wt % and grains passing through #200 mesh are contained in 35 wt %. A volatile matter is contained in 1 wt % or less. The izod impact strength (ISO 180) is 50 kg·cm/cm or more (23° C. ¼″) and 10 kg·cm/cm or more (−30° C. ¼″). As for the impact modifier for use in transparency, an apparent specific gravity is 0.32 g/cc, and grains not passing through #24 mesh are contained in 2 wt % and grains passing through #200 mesh are contained in 20 wt %. A volatile matter is contained in 1 wt % or less. The izod impact strength (ISO 180) is 80 kg·cm/cm or more (23° C.). 
     The impact modifier is contained in 0.1 to 5 parts by weight based on 100 parts by weight of the poly(alkylene carbonate) resin. If the concentration of the impact modifier deviates from the above range, a hardened product may be easily broken, which causes deterioration of durability thereof. 
     The foaming agent is an additive used in forming cells to prepare a foaming body, by inputting gas in polymer within a state where polymer materials and various kinds of sub-raw materials are added, in physical, chemical and mechanical methods, through regulation of conditions, such as temperature, pressure, time and the like, and thereby to forming cells, or artificially forming gas. Among chemical foaming agents, sodium bicarbonate, ammonium carbonate, ammonium bicarbonate, ammonium nitrite, an azide compound, sodium borohydride, soft metal, or the like, causes an endothermic reaction at the time of thermal decomposition. Inorganic foaming agents showing irregular decomposition and generating gas somewhat slowly may be used. Since the gas generated by decomposition of the foaming agent is almost carbon dioxide, the foaming agent may be used in manufacturing an open-cell structured foaming body due to large permeability thereof to the resin. The foaming agent may be used with an organic foaming agent including azodicarbonamide (ADCA), N,N′-dinitrosopentamethylenetetramine (DNPA), 4,4′-oxybis(benzenesulfonylhydrazide) (OBSH), p-toluenesulfonylhydrazide (TSH). Any one or more selected from the group consisting of inorganic foaming agents and organic foaming agents. 
     The foaming agent is contained in 0.5 to 20 parts by weight based on 100 parts by weight of the poly(alkylene carbonate) resin, and can improve light weight, elasticity, insulation property, soundproofing property, and absorbency, and provide an excellent appearance, through combination with other components within the above range. 
     The flame-retardant agent may be any one or more selected from the group consisting of phosphorus based compounds, silicon based compounds, halogen based compounds, and metal hydride compounds, and can give, to the products, impact relieving property, cushion feeling, excellent touch feeling, cost reduction, dimensional stability, adiabaticity, soundproofing property, buoyancy, absorbency, decorating property, or the like. 
     The flame retardant agent is contained in 0.1 to 200 parts by weight based on 100 parts by weight of the poly(alkylene carbonate) resin, thereby improving flame retardant property and flameproofing property, and expressing a synergy effect through combination with other components. 
     In the present invention, the flexibilizer is referred to a single molecular type liquid material or a polymer type solid material, which can be processed below a decomposition temperature of a polymer material or lower for use in improving processability of the polymer, and can be added to improve flexibility of the polymer material. The flexibilizer can minimize the generation of a frictional heat, improve physical properties such as elasticity, adhesive property, flexibility, and or the like, improve thermal stability of products, and easily melt a pallet type polymer material. 
     In the present invention, as the flexibilizer, DAIFATTY-101 or MTGA of the structural formula below may be used. Even though the optimum content of the flexibilizer, based on the poly(alkylene carbonate) resin, is a level of ⅙ as compared with a common phthalate based plasticizer used for the polyvinyl chloride resin, it exhibits mechanical properties and hardness equal to or superior to the common phthalate based plasticizer, and has excellent migrant resistant property (migration of plasticizer). 
     
       
                 
         
             
             
         
      
     
     MTGA(Bis(2-(2-(2-methoxyethoxy)ethoxy)ethyl glutarate) 
     The flexibilizer also includes a solid type polyacrylic acid or polyacrylates obtained by a polymerization reaction or esterification reaction of acrylic acid or acrylates. Here, as the flexibilizer, an acrylic resin obtained by treating 60 to 85% of polymethylmethacrylate, 15 to 5% of polyethylacrylate, and 25 to 5% of polybutylacrylate with a polar solvent may be used in order to maximize mechanical properties and heat resistant property, and PA828 (LG Chemical) may be one example of the flexibilizer. 
     The flexibilizer is contained in 0.1 to 50 parts by weight based on 100 parts by weight of the poly(alkylene carbonate) resin, thereby remarkably improving fusion and processability through combination with other components, increasing elasticity, adhesive property, and flexibility, and enhancing thermal stability. 
     In the present invention, a obliterating power improver is for improving a whiteness, tinting strength, an aesthetic effect, and coverage, and is applicable to sheets for wall paper or decoration. An example of the coverage improve may be titanium dioxide, but not limited thereto. 
     In the present invention, an elasticity provider can improve durability, and particularly is applied to foaming products of synthetic leather, thereby maximizing an effect of improving elasticity and enhancing dimensional stability. Examples of the elasticity provider may include NBR or modified polyurethane. 
     Meanwhile, moisture is condensed due to the breathing of contents packaged (package of mainly vegetables, fruits, and food) by a material mainly used in plastic wrap for package or difference of temperature between an inside surface and an outer surface of the packaging. As a result, the contents are scarcely seen when a customer purchases the products, and thus, freshness of the contents is difficult to confirm, which causes a purchase degree to be dropped. In addition, when the condensed moisture is contacted with the packaged contents, the contents may be easily spoiled. In the present invention, an antifogging agent can prevent these problems. A surfactant may be used as the antifogging agent. 
     In another general aspect, a resin composition for a sheet includes: 0.1 to 100 parts by weight of an strength controller, 0.1 to 50 parts by weight of a flexibilizer, 0.1 to 5 parts by weight of a compatibilizer, 0.1 to 30 parts by weight of a obliterating power improver, 0.1 to 200 parts by weight of a filler, and 0.1 to 5 parts by weight of a lubricant, based on 100 parts by weight of a poly(alkylene carbonate) resin. 
     In another general aspect, an eco-friendly poly(alkylene carbonate) resin composition for a decorative sheet includes at least one selected from the group consisting of 2 to 50 parts by weight of an strength controller, 2 to 50 parts by weight of a dimensional stabilizer, 0.1 to 30 parts by weight of a flexibilizer, 0.1 to 30 parts by weight of an impact modifier, 5 to 30 parts by weight of a coverage improver, and 0.1 to 5 parts by weight of a filler, based on 100 parts by weight of a poly(alkylene carbonate) resin. 
     A poly(alkylene carbonate) resin (GreenPol) in the eco-friendly poly(alkylene carbonate) resin composition is excellent in tensile strength and tear strength, due to structural distinctiveness of itself and good miscibility with processing additives, and is remarkably excellent in particularly elongation (stretching property) and printability, as compared with common plastics. These physical properties are importantly required for use in a high-priced membrane in the decorative sheets. In particular, the poly(alkylene carbonate) resin (GreenPol) is excellent in a flameproofing characteristic, such as smoke density, by 1/600 of that of the common plastics. 
     Here, the eco-friendly poly(alkylene carbonate) resin composition for a decorative sheet may be used as a transparent or opaque soft decorative sheet, or a transparent or opaque hard decorative sheet, by combination with the strength controller, the dimensional stabilizer, the flexibilizer, the impact modifier, the obliterating power improver, or the lubricant. 
     The eco-friendly poly(alkylene carbonate) resin composition for the transparent soft decorative sheet includes 2 to 50 parts by weight of the strength controller, 2 to 50 parts by weight of the dimensional stabilizer, 0.1 to 30 parts by weight of the flexibilizer, and 0.1 to 5 parts by weight of the lubricant. 
     The eco-friendly poly(alkylene carbonate) resin composition for the opaque soft decorative sheet includes 2 to 50 parts by weight of the strength controller, 2 to 50 parts by weight of the dimensional stabilizer, 0.1 to 30 parts by weight of the flexibilizer, 5 to 30 parts by weight of the obliterating power improver, and 0.1 to 5 parts by weight of the lubricant. 
     The eco-friendly poly(alkylene carbonate) resin composition for the transparent hard decorative sheet includes 2 to 50 parts by weight of the strength controller, 2 to 50 parts by weight of the dimensional stabilizer, 0.1 to 30 parts by weight of the impact modifier, and 0.1 to 5 parts by weight of the lubricant. 
     The eco-friendly poly(alkylene carbonate) resin composition for the opaque hard decorative sheet includes 2 to 50 parts by weight of the strength controller, 2 to 50 parts by weight of the dimensional stabilizer, 0.1 to 30 parts by weight of the flexibilizer, 5 to 30 parts by weight of the obliterating power improver, and 0.1 to 5 parts by weight of the lubricant. 
     The poly(alkylene carbonate) resin is excellent in tensile strength and tear strength, due to structural distinctiveness of itself and good miscibility with processing additives, and is remarkably excellent in particularly elongation (stretching ratio) and printability, as compared with common plastics. These physical properties are importantly required for use in a high-priced membrane in the decorative sheets. Also, the poly(alkylene carbonate) resin is excellent in a flameproofing characteristic (particularly smoke density), by 1/600 of that of the common plastics.

     Example 155 
     100 parts by weight of a poly(propylene carbonate) resin (SK Innovation Company), 5 parts by weight of an strength controller (polylactic acid, SK Innovation Company), 5 parts by weight of a flexibilizer (DAIFATTY-101, DAIHACHI Company in Japan), 7.5 parts by weight of a obliterating power improver (KA100, Cosmo Chemistry), 20 parts by weight of a filler (Omya-2T, Omya Korea Company), and 2 part by weight of a lubricant (stearic acid, OCI) were put in a Henschel mixer, and then dry blended for 20 minutes. The dry blended mixture was put into a compounding extruder at 160° C. to be pelletized. This was prepared into a sheet semi-finished product through a compounding process (mixing rolls and warming rolls) and a calender process, followed by print, primer, and surface treatment processes, and a laminating process, thereby producing a decorative sheet finished product. 
     Examples 156 to 166 
     Examples 156 to 166 were performed by the same method as Example 155, except that the strength controller was controlled in 10, 20, 50, 75, and 100 parts by weight for Examples 156 to 160, respectively; and SKflex by SK Innovation Company was used as the flexibilizer and controlled in 1, 2.5, 5, 10, 20, and 50 parts by weight for Examples 161 to 166, respectively.

     Example 213 
     100 parts by weight of a poly(propylene carbonate) resin (SK Innovation Company), 5 parts by weight of pellet type modified polyester by BASF Company as an strength controller, 5 parts by weight of a flexibilizer (DAIFATTY-101, DAIHACHI Company in Japan), 7.5 parts by weight of a obliterating power improver (KA100, Cosmo Chemistry), 20 parts by weight of a filler (Omya-2T, Omya Korea), and 2 part by weight of a lubricant (stearic acid, OCI) were put in a Henschel mixer, and then dry blended for 20 minutes. The dry blended mixture was put into a compounding extruder at 120° C. to be pelletized. This was prepared into a sheet semi-finished product through a compounding process (mixing rolls and warming rolls) and a calender process, followed by print, primer, and surface treatment processes, and a laminating process, thereby producing a decorative sheet finished product. 
     Examples 214 to 224 
     Examples 214 to 218 were performed by the same method as Example 1, except that the strength controller was controlled in 10, 20, 50, 75, and 100 parts by weight, respectively, and Examples 219 to 224 were performed by the same method as Example 213, except that SKflex by SK Innovation Company was used as the flexibilizer and controlled in 1, 2.5, 5, 10, 20, and 50 parts by weight for Examples 219 to 224, respectively.

     Example 271 
     100 parts by weight of a poly(propylene carbonate) resin (SK Innovation Company), 5 parts by weight of a liquid polymer type modified polyester by Aekyung Chemical Company as an strength controller, 5 parts by weight of a flexibilizer (DAIFATTY-101, DAIHACHI Company in Japan), 7.5 parts by weight of a obliterating power improver (KA100, Cosmo Chemistry), 20 parts by weight of a filler (Omya-2T, Omya Korea), and 2 part by weight of a lubricant (stearic acid, OCI) were put in a Henschel mixer, and then dry blended for 20 minutes. The dry blended mixture was put into a compounding extruder at 130° C. to be pelletized. This was prepared into a sheet semi-finished product through a compounding process (mixing rolls and warming rolls) and a calender process, followed by print, primer, and surface treatment processes, and a laminating process, thereby producing a decorative sheet finished product. 
     Examples 272 to 282 
     Examples 272 to 276 were performed by the same method as Example 273, except that the strength controller was controlled in 10, 20, 50, 75, and 100 parts by weight, respectively, and Examples 277 to 282 were performed by the same method as Example 273 except that SKflex by SK Innovation Company was used as the flexibilizer and controlled in 1, 2.5, 5, 10, 20, and 50 parts by weight, respectively.

     Example 329 
     100 parts by weight of a poly(propylene carbonate) resin (SK Innovation Company), 5 parts by weigh of polymethylmethacrylate by LG Company as the strength controller, 5 parts by weight of a flexibilizer (DAIFATTY-101, DAIHACHI Company in Japan), 7.5 parts by weight of a obliterating power improver (KA100, Cosmo Chemistry), 20 parts by weight of a filler (Omya-2T, Omya Korea), and 1 part by weight of a lubricant (stearic acid, OCI) were put in a Henschel mixer, and then dry blended for 20 minutes. The dry blended mixture was put into a compounding extruder at 160° C. to be pelletized. This was prepared into a sheet semi-finished product through a compounding process (mixing rolls and warming rolls) and a calender process, followed by print, primer, and surface treatment processes, and a laminating process, thereby producing a decorative sheet finished product. 
     Examples 330 to 340 
     Examples 330 to 340 were performed by the same method as Example 329, except that the strength controller was controlled in 10, 20, 50, 75, and 100 parts by weight for Examples 330 to 334, respectively; and SKflex by SK Innovation Company was used as the flexibilizer and controlled in 1, 2.5, 5, 10, 20, and 50 parts by weight for Examples 335 to 340, respectively.

     Example 387 
     100 parts by weight of a poly(propylene carbonate) resin (SK Innovation Company), 5 parts by weigh of ethylene vinylacetate by Samsung Total Company as the strength controller, 5 parts by weight of a flexibilizer (DAIFATTY-101, DAIHACHI Company in Japan), 7.5 parts by weight of a obliterating power improver (KA100, Cosmo Chemistry), 20 parts by weight of a filler (Omya-2T, Omya Korea), and 2 part by weight of a lubricant (stearic acid, OCI) were put in a Henschel mixer, and then dry blended for 20 minutes. The dry blended mixture was put into a compounding extruder at 120° C. to be pelletized. This was prepared into a sheet semi-finished product through a compounding process (mixing rolls and warming rolls) and a calender process, followed by print, primer, and surface treatment processes, and a laminating process, thereby producing a decorative sheet finished product.

     Example 446 
     100 parts by weight of a poly(propylene carbonate) resin (SK Innovation Company), 5 parts by weigh of thermoplastic copolyester elastomer by LG Chemical Company as the strength controller, 5 parts by weight of a flexibilizer (DAIFATTY-101, DAIHACHI Company in Japan), 7.5 parts by weight of a obliterating power improver (KA100, Cosmo Chemistry), 20 parts by weight of a filler (Omya-2T, Omya Korea), and 2 part by weight of a lubricant (stearic acid, OCI) were put in a Henschel mixer, and then dry blended for 20 minutes. The dry blended mixture was put into a compounding extruder at 150° C. to be pelletized. This was prepared into a sheet semi-finished product through a compounding process (mixing rolls and warming rolls) and a calender process, followed by print, primer, and surface treatment processes, and a laminating process, thereby producing a decorative sheet finished product. 
     Examples 447 to 457 
     Examples 447 to 457 were performed by the same method as Example 446, except that the strength controller was controlled in 10, 20, 50, 75, and 100 parts by weight for Examples 447 to 451, respectively; and SKflex by SK Innovation Company was used as the flexibilizer and controlled in 1, 2.5, 5, 10, 20, and 50 parts by weight for Examples 452 to 457, respectively.

     As described above, products made of the eco-friendly poly(propylene carbonate) resin composition according to the present invention never generate harmful gases and dioxine at the time of combustion, which are big weaknesses of polyvinyl chloride materials. In addition, the present invention has a smoke density corresponding to about 1/600 of that of the polyvinyl chloride resin, and thus exhibits excellent flameproofing property, thereby never generating any harmful gases during processing or the use of products. Furthermore, the present invention can efficiently utilize carbon dioxide, which is a major contributor to global warming, and can remarkably improve physical properties, such as flexibility, strength, stretching property, and the like, above the level of the existing polyvinyl chloride resin, even without using phthalate based plasticizers and stabilizers, which are processing additives harmful to the human body. 
     Furthermore, the present invention is not easily broken in the winter time nor requires any post processing treatment, such as printing, surface treatment, and the like, thereby improving economic feasibility, by applying a calender processing method allowing mass production, rather than an extrusion processing method, which is regarded as the biggest disadvantage of alternatives for the existing polyvinyl chloride.
