==Materials used==
Plastic wrap was initially{{When|date=September 2023}} created from [[polyvinyl chloride]] (PVC), which remains the most common component globally. PVC has an acceptably-low permeability to water vapor and oxygen,<ref>{{Cite book|url=https://books.google.com/books?id=-kO5CgAAQBAJ&q=pvc%2520cling%2520film%2520permeability&pg=PA488|title=Food: The Chemistry of its Components: 6th Edition|last=Coultate|first=Tom|date=2015-08-17|publisher=Royal Society of Chemistry|isbn=9781849738804|url-status=live|archive-url=https://web.archive.org/web/20160428065131/https://books.google.co.th/books?id=-kO5CgAAQBAJ&pg=PA488&lpg=PA488&dq=pvc+cling+film+permeability&source=bl&ots=b5SHT3RVQ2&sig=33Cn0KRsLcwYeheOqGGISAN9KC4&hl=en&sa=X&ved=0ahUKEwiNt9jixOrLAhVGA44KHbK6CGUQ6AEINDAE#v=onepage&q=pvc%2520cling%2520film%2520permeability&f=false|archive-date=2016-04-28}}</ref> helping to preserve the freshness of food. There are concerns about the transfer of [[plasticizers]] from PVC into food.{{
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>

===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 their low price and convenience; however, there has been an increased health concern because of the possibility of releasing undesirable chemicals from plastic materials into food products. Plastic packages are made of various materials such as polyethylene, low-density polyethylene, etc. Additives, including
"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.
