Talk:Plastic wrap

message: Paramedics use plastic wrap for burn victims, In New Zealand at least. Heard this from an (recently) ex-paramedic studying medicine with me. Said they carried it on the ambulance with them. I guess to wrap up the victim to reduce infection, and that it won't stick to the patient.
googled 'gladwrap burn victim'.
ctrl+F 'glad' in those links.

thread_title:  Casimir Effect? 

message: Blissfulpain: Just wondering if there is an environmentally firendly alternative to plastic wrap? After some googling i can't seem to find much on the subject... biodegradable plastic bags, but no biodegradable plastic wrap.  I'll keep looking and report back if i find something about it
This is CB Kam of Fine Vantage Limited. We are making LDPE plastic wrap so I think I can share some of my thoughts with you and I hope that can help.
There are two kind of plastic wrap, PVC and PE. You can run a search on Google about PVC and you will notice that it is both toxic and not environmental friendly. PVC is very popular in food catering (supermarket and hotel use) application. For the household plastic wrap, many consumers prefer PE. It is the safest plastic to use in terms of both food grade and environmental impact. 
Given said, even though it is common to recycle PE, there is not too many people recycle plastic wrap. It is because the film is already very thin in gauge and there is not much tonnage if you try to recycle plastic wrap. You can find your recycle effort much more effective when you try to recycle your shampoo bottles. 
There is also not such a thing about bio-degradable plastic wrap. It is because plastic wrap demands a very high tensile strength film property and haze free finished products. The overall plastic wrap global tonnage is relatively small and it won't justify to create a PE resin that is both bio-degradable and suitable to make PE plastic wrap.
We in Fine Vantage are trying to make the product safer to use so we are offering Food Grade unit box with ink that has no heavy metal on our products. We educate our supermarket buyers whenever we have a chance. 
If you are much concern about plastic wrap in terms of environmental issues and food hygience, I strongly suggest you to stay away from PVC film (catering and household) and buy only PE base plastic wrap. You may want to express your concerns with your favorite supermarket. Maybe he will do something about it.
Thank you and I hope you find my explaination useful.
Best Regards,
cbkam@finevantage.com
WHY IS THERE NOTHING ON THE HISTORY OF THE PRODUCT?

While plastic litter remains a serious problem, in areas where trash feeds a trash to power incinerator, plastic products are actually quite friendly when disposed of properly.  Paper products produce 10% ash when incinerated, but plastic is almost pure energy.  It's like burning oil after using it for other things first.  The temperature is high enough to prevent formation of dioxins and other nasty by-products of plastics containing chlorine. https://www.eia.gov/energyexplained/biomass/waste-to-energy.php StuartGathman (talk) 17:21, 1 August 2020 (UTC)
thread_title:  Environmental Concerns 

message: Isn't it the case that this is commonly known as 'Glad wrap' in Australia and New Zealand, because the leading brand is so prevalent. In fact I believe it is a problem, in that the Glad company is constantly trying to prevent their trademark becoming genericised (see for example this partial article). I would have thought some mention of these issues should be made. -- Solipsist 09:39, 13 December 2005 (UTC)

thread_title:  Overprecise! 

message: Hello good people. This is my very first contribution, so please bear with me, but I do have a personal knowledge on this subject. I worked for nine years with Douglas Lyons Ford, the person who claimed to have invented "Glad Wrap" in Australia. My knowledge of the product comes from personal communication to me from Dr Ford.
The product was never made from PVC - it was always polyethylene blow-molded with a "stickifier" and slit into rolls. To the best of my knowledge, plasticized PVC has always had health concerns and was not initially given 21 CFR (FDA) approval for food contact. Poly was an equally cheap alternative with approval for food contact. Although Doug developed the product in Australia, he was an employee of Union Carbide, an American company. It was therefore necessary to consider the potential for a new product developed in Australia to be saleable in the United States. The product has been available in Australia since the mid-1960's and it was the first retailed sticky plastic film in Australia, but there were earlier plastic films - maybe these were PVC?
I do have more on the Australian Glad Wrap story, but would appreciate some comments please.

text: The clinging is due to the van der Waals force between the chlorine atoms, which is rather particular with PVC (and Saran = PVDC, its copolymer). This is e.g. explained in James N. Spencer, George M. Bodner, Lyman H. Rickard, Chemistry: Structure and Dynamics, 5th ed. (Wiley, 2010), p. 370. And I am sorry Macaddct1984, but you are wrong, plus you claim is not backed by your sources (nowhere did even the word "van der Waals" appear there).

thread_title: Date of invention?

message: Some of the information under the "Materials used" section is contradictory. 
In the third paragraph it is stated: 
 However, LDPE does not possess the same barrier qualities to oxygen, aroma, and flavor molecules that vinylidene chloride
 copolymers do, making the new formulation a lower quality plastic wrap, as it is not as useful in protecting from spoilage or
 flavour loss.[citation needed] PVC is not impermeable, but adheres well. LDPE is impermeable but doesn't cling as well.[1] 
That in itself is contradictory, but further down we have: 
I AM A NEW COMMENTER:: sorry friend but the contradictions are above: if LDPE does not possess the same barrier qualities (etc) then how is it the impermeable one? the author made his mistake there, and not below, which would seem to follow the correct line of thinking.
 PVdC has better barrier properties than the more-permeable LDPE, making the foods wrapped in it less subject to freezer
 burn.[citation needed] However, LDPE is substantially cheaper and easier to make.
I don't know which is true, but if I ever find out I will correct it if it still needs to be.  —Preceding unsigned comment added by Caichofschi (talk • contribs) 02:25, 8 November 2010 (UTC)

thread_title: Plastic Film

message: I think that this article has become biased over it's many edits. In the first paragraph, it is mentioned that cling film is made either from PVC, LDPE or LLDPE film, while the vast majority of film being produced is still PVC. It then goes on to mention that LDPE is a 'safer' alternative. It should be addressed that the use of the terms 'toxic' and 'much safer' should not be used in describing either PVC and PE based cling films as these are unproven generalisations that don't reflect the current status of either the PVC or the PE cling film markets.
This comment should be completely stricken: This article is about a plastic layer used for short-term preservation of domestic foods. For a plastic wrap often used in bulk packaging, see Shrink wrap. -- The vast majority of the cling wrap produced world wide for food processing is PVC based cling wrap used in meat, cheese and vegetable packaging on industrial farms and food processing plants  while shrink wrap is a completely different product.
The reality is that PE is cheaper to make largely due to the lower price per kilo of PE based films in contrast to PVC resin which has risen dramatically in recent years due to increased demand in other PVC sectors (the construction industry makes up more than 2/3 of the PVC market). In the end, PE is a cheaper version of the PVC film. To evaluate one or the other as being better or worse, safer or more dangerous, is not the place of an wikipedia.org article and I would suggest striking any biased language from the entirety of the article. I would suggest instead that the arguments of environmental and public health be summarised into one paragraph where it is expressed that there is no definitive consensus on the topic. Which is true. 
Historically, PVC did contain additives that were considered potentially dangerous in specific situations.  However no studies have connected the use of these PVC cling films directly to health problems. However, due to legislation and restrictions on the levels of BEPA migration, among others, the production of PVC cling film adheres to strict regulation and as a result has largely changed the additives that are used as plasticisers in the film and the amounts of migration of such additives is minimal and well within the accepted range of public safety. An inaccuracy in the article is that countries have banned the use of PVC cling film. I tried to find information to support this, but what I did find is that no country has banned the use of PVC cling film.
Regarding the recyclability of the film, modern recycling facilities are capable to process PVC film (at least in Europe) and the problem with processing PVC cling film waste was largely due to the high temperatures necessary to process it. See http://www.vinylplus.eu/uploads/Progress%20report%202013/VinylPlus_-_AR2012_-_LONG_-_V17.pdf It seems the biggest barrier to recyclability is the relative low amount of cling film that is submitted for recycling and that public awareness/willingness could be affecting the success of PVC recycling.
I also think that there should be a sub-heading dedicated to specifying the differences in the qualities between PVC and PE based cling films and reiterated that the vast majority of the world's cling film production are PVC based films. In addition it should be clarified that the consumer/catering wrap industry makes up only a small percentage of cling film use. Also, to my knowledge, all major producers mentions (GLAD and SARAN) produce both PVC and LDPE version of their films depending on the use and market segment (premium, generic) of the film. If this information cannot be confirmed it should be omitted. In addition, mention of Glad Press'N'Seal is not related to this article as it is not a 'cling film' and certainly doesn't warrant an entire paragraph in the article.
As mentioned before, it is critical language describing PVC and PE cling films be stricken. PE cling film is almost exclusively (in volume terms) as pallet wrap and a link to this use should be made and a link to the Stretch Wrap article should be made since these are the same thing, just different uses and the terms are often interchangeable. Alternative uses of cling wrap can also be listed, for example, short-term treatment of burn victims, protective wrap to protect new tattoos. In both cases, PVC film is preferable to PE cling films due to the breathability of PVC which doesn't suffocate live tissue. An antibacterial agent can even be added which can aid in fighting infection. However, it is incorrect to say that either PE or PVC is more hygienic. To my knowledge there have been no studies on this and I believe that when correctly applied, the hygienic qualities will be the same.  — Preceding unsigned comment added by Rosscoland (talk • contribs) 08:33, 17 April 2014 (UTC)
