Plastic wrap

Plastic wrap, cling film, Saran wrap, cling wrap, 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.

Plastic wrap was initially created from polyvinyl chloride (PVC), which remains the most common component globally. PVC has an acceptably-low permeability to water vapor and oxygen,helping to preserve the freshness of food. 

PE cling film is a general-purpose cling film suitable for all food wrapping. Although not as 'clingy' as PVC cling film, it has the same food freshness and preservation benefits as PVC cling film.
