Blown-film extrusion involves a molten resin extruded through a circular die and filling the tube with air. The air within the tube stretches the film to obtain the desired thickness. Co-Extrusion Film Co-extrusion is a process that simultaneously extrudes two or more thermoplastic resins into a multi layer film, which has distinguished individual layers. Corona Treatment Corona treatment is a surface treatment process that improves the bonding characteristics of most materials such as: paper, films, foils, and polymers by raising surface energy. EVA (Ethylene Vinyl Acetate) Ethylene-vinyl acetate the copolymer of ethylene and vinyl acetate. It is a polymer that approaches elastomeric materials in softness and flexibility, yet can be processed like other thermoplastics. The material has good clarity and gloss, barrier properties, low-temperature toughness, stress-crack resistance, hot-melt adhesive and heat sealing properties and resistance to UV radiation. Flexible Packaging Flexible packaging is material such as plastics, paper or foil used to form packaging for items such as bags, pouches, envelopes etc. Flexographic Printing Process by which solvent or water based ink is applied to polyethylene films. Flexographic printing describes the process commonly used in the packaging industry using a roller with a flexible rubber-like surface coated with quick-drying ink. Lamination The bonding of two or more substrates through a process of adhesive lamination. During the lamination process, different layers of materials are laminated together, using solvents or nonsolvent, in order to get the desired combination. LDPE: Low density polyethylene LLDPE: Linear low density polyethylene MDPE: Medium density polyethylene Mono-Layer Film Mono-layer film is the process of extruding material into a single layer of film. A film can be defined as a thin layer of material usually made of transparent plastic often used to cover or wrap things. Polyethylene A thermoplastic commodity heavily used in consumer products; Polyethylene is created through polymerization of ethylene. In the polymer industry the name is sometimes shortened to PE. RTO (Regenerative Thermal Oxidiser) Air Pollution Control using RTO technology ensures high energy efficiency, around 95%, is achieved by recovering and re-using the excess heat energy which is created in the process of combusting the organic materials contained in the air stream. VOC Emissions Volatile Organic Compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. WetFlex WetFlex is the breakthrough technology available only from Sun Chemical that delivers wet-on-wet flexographic printing. It is designed to meet the needs of the flexible packaging market for improved print quality, efficiency, and low environmental impact.
