A common, cheaper alternative to PVC is [[low-density polyethylene]] (LDPE). It is less adhesive than PVC, but this can be remedied by adding [[linear low-density polyethylene]] (LLDPE), which also increases the film's [[tensile strength]].<ref>{{Cite journal|last1=Krishnaswamy|first1=Rajendra K.|last2=Lamborn|first2=Mark J.|date=2000|title=Tensile properties of linear low density polyethylene (LLDPE) blown films|url=https://onlinelibrary.wiley.com/doi/abs/10.1002/pen.11370|journal=Polymer Engineering & Science|language=en|volume=40|issue=11|pages=2385–2396|doi=10.1002/pen.11370|issn=1548-2634}}</ref>
In the US and Japan, plastic wrap is sometimes produced using [[polyvinylidene chloride]] (PVdC), though some brands, such as [[Saran (plastic)|Saran]] wrap, have switched to other formulations due to environmental concerns.<ref>{{Cite news|url=http://host.madison.com/business/ceo-explains-why-sc-johnson-made-saran-wrap-less-sticky/article_8987a920-fec9-5567-8b47-3067b3f83ff6.html|title=CEO Explains Why SC Johnson Made Saran Wrap Less Sticky, Hurting Sales|first=Michael|last=Burke|work=Madison.com|access-date=2017-06-20|url-status=live|archive-url=https://web.archive.org/web/20170620202432/http://host.madison.com/business/ceo-explains-why-sc-johnson-made-saran-wrap-less-sticky/article_8987a920-fec9-5567-8b47-3067b3f83ff6.html|archive-date=2017-06-20}}</ref>

===Purpose===
[[File:Daujėnų naminė duona.JPG|thumb|Bread wrapped in plastic wrap]]
The most important role plastic wrap plays in [[food packaging]] is protection and preservation. Plastic wrap can prevent food from perishing, extend its shelf-life, and maintain the quality of food. Plastic wrap generally provides protection for food from three aspects: chemical (gases, moisture, and light), biological (microorganisms, insects and animals), and physical (mechanical damage). In addition to food protection and preservation, plastic wrap can also reduce [[food waste]], tag food information, ease the distribution processes, and increase product visibility and microwavability.<ref>{{Cite journal|last1=Marsh|first1=Kenneth|last2=Bugusu|first2=Betty|date=2007|title=Food Packaging—Roles, Materials, and Environmental Issues|journal=Journal of Food Science|volume=72|issue=3|pages=R39–R55|doi=10.1111/j.1750-3841.2007.00301.x|pmid=17995809|s2cid=12127364 |issn=1750-3841|doi-access=free}}</ref>

===Health concern===
Plastic materials are widely used in the food industry due to
"It is true that substances used to make plastics can leach into food," says Edward Machuga, Ph.D., a consumer safety officer in the [[Food and Drug Administration|FDA]]'s [[Center for Food Safety and Applied Nutrition]]. “But as part of the approval process, the FDA considers the amount of a substance expected to migrate into food and the toxicological concerns about the particular chemical.” A couple of cases have caught media attention in recent years. One case is in regard to [[diethylhexyl adipate]] (DEHA). DEHA is a plasticizer, a substance added to some plastics in order to make them flexible.
