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 [[lubricant]]s, [[plasticizer]]s, [[UV-absorber]]s, [[Colourant|colorants]], and [[antioxidant]]s, are added into plastic materials in order to improve the quality and properties of the plastics. Besides, plastic materials are often coated and printed in the final processes, in which inks and [[varnish]]es are used. Although the barrier properties of the plastic packages provide protection of foods from external contaminations, the additives and coating materials in the plastic packages are able to penetrate into foods and cause health-related issues.<ref>{{Cite journal|last1=García Ibarra|first1=Verónica|last2=Rodríguez Bernaldo de Quirós|first2=Ana|last3=Paseiro Losada|first3=Perfecto|last4=Sendón|first4=Raquel|date=2018-06-01|title=Identification of intentionally and non-intentionally added substances in plastic packaging materials and their migration into food products|journal=Analytical and Bioanalytical Chemistry|volume=410|issue=16|pages=3789–3803|doi=10.1007/s00216-018-1058-y|pmid=29732500|s2cid=19148865|issn=1618-2650}}</ref>
 
"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. There are public concerns about DEHA exposure while consuming food with plastic wraps([https://pvcclingfilm.com/ Cling Film]). There are potentials of exposure to DEHA; however, the levels of the exposure are much lower than the no toxic effect levels in animal studies. Another case is in regard to the dioxins, labeled as "likely human carcinogen" by the Environmental Protection Agency. The public has been misled by the claims that plastics contain dioxins {{Citation needed|date=July 2022}}, while Machuga stated that no evidence that shows plastic containers or films contain dioxins was seen by the FDA {{Citation needed|date=July 2022}}. According to writing in FDA Consumer Magazine as of November 2002, when used properly the use of plastic wrap in food preparation does not pose danger to human health.<ref>{{Cite journal|title=Plastics and the Microwave|last=Meadows|first=Michelle|journal=FDA Consumer|date=2002|volume=36|issue=6|page=30|doi = 10.1037/e542632006-006|pmid=12523298|url = http://permanent.access.gpo.gov/lps1609/www.fda.gov/fdac/features/2002/602_plastic.html|archive-url = https://web.archive.org/web/20100318121541/http://permanent.access.gpo.gov/lps1609/www.fda.gov/fdac/features/2002/602_plastic.html|archive-date = 18 Mar 2010}}</ref>
