How is plastic wrap made?
Plastic wrap, known as cling-film in the United Kingdom, is a thin polymer material, approximately 0.13mm (0.003in) thick, typically used for sealing food items in containers to keep them fresh. The 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 with no adhesive or other devices. Commonly known brands of plastic wrap, in the United States, include Saran wrap and Stretch-Tite. In Australia and New Zealand, Glad wrap is the leading brand, known well enough to make its manufacturer concerned about its trademark becoming genericized.[1] In Hong Kong, a company named Fine Vantage Limited is the major private label LDPE plastic wrap manufacturer.
