Cling film, cling wrap, fcling wrap film,food wrap,plastic wrap or pliofilm 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 0.5 Thousandth of an inch (12.5 μm) thick.
Although the trend has been to produce thinner plastic wrap, particularly for household use (so very little stretch is needed),so now the majority of brands on shelves around the world are 8mic 9mic or 10 mic thick. Most use 10mic.
