'''Plastic wrap''', '''cling film''', '''[[Saran (plastic)|Saran]] wrap''', '''cling wrap''', '''[[The Glad Products Company|Glad]] wrap''' or '''food wrap''' is a thin [[plastic film]] typically used for sealing [[food]] items in containers to keep them fresh over a longer period of time. Plastic wrap, typically sold on rolls in boxes with a cutting edge, clings to many smooth surfaces and can thus remain tight over the opening of a container without [[adhesive]]. Common plastic wrap is roughly 0.0005 inches (12.7 μm) thick.<ref>{{cite web|url=http://www.matweb.com/search/datasheet.aspx?matguid=57c29e222a7749d58267c18e9e18b637|title=Dow Saran Wrap 3 Plastic Film|access-date=10 December 2016}}</ref><ref>{{cite web|url=http://www.glad.com/faqs/plasticwrap.php|title=FAQs: Microwave, Dishwasher & Freezer Q&A|date=20 November 2014|access-date=10 December 2016|url-status=live|archive-url=https://web.archive.org/web/20110223154555/http://www.glad.com/faqs/plasticwrap.php|archive-date=23 February 2011}}</ref> The trend has been to produce thinner plastic wrap, particularly for household use (where very little stretch is needed), so now the majority of brands on shelves around the world are 8, 9 or 10 μm thick.

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|
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.
