'''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|
==Materials used==
Plastic wrap was initially{{When|date=September 2023}} created from
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|
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|

===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|

===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.
===Environmental concerns===
The accumulation of [[Plastic pollution|plastic debris]] on the Earth threatens both wildlife and the environment. Plastic debris might choke or trap wildlife, and it could also penetrate toxic compounds into ecosystems. This land-originated problem has become a problem in ocean ecosystem as well since streams and rivers which are close to the land have carried the plastic debris into the coast, and currents transfer it to everywhere in the ocean. Plastic debris is a potential danger to all forms of aquatic life. Some marine species, like sea turtles, take plastic as prey items by mistake. Besides, some species might even pick up plastics and feed their offspring, which cause huge problems on growth and even cause mortality. Toxic compounds in plastics can disrupt hormone regulation in the cells of organisms, which can lead to alteration of animals’ mating behavior, reproductive ability, and even cause the development of tumors. Plastic debris could be a big threat to lives in the ocean.<ref>{{Cite journal|
A study shows that using recycled plastic materials can reduce the environmental impacts significantly as a result of minimizing exploration, mining and transportation of natural gas and oil. One of the possible ways to increase the recycling rate is adding fibrous reinforcement into plastics. The environmental impact has been assessed using the life cycle assessment method. The results showed that plastics with fibrous reinforcement added can sharply reduce resource usage and global warming in civil applications.<ref>{{Cite journal|title= Environmental impact assessment of composites containing recycled plastics|pages=131–139|journal=Resources, Conservation and Recycling|volume=60|doi=10.1016/j.resconrec.2011.11.006|date=March 2012|last1=Rajendran|first1=Saravanan|last2=Scelsi|first2=Lino|last3=Hodzic|first3=Alma|last4=Soutis|first4=Constantinos|last5=Al-Maadeed|first5=Mariam A.}}</ref>
