Materials Used Of PE Cling Wrap

Plastic PE cling 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. There are concerns about the transfer of plasticizers from PVC into food. PE cling wrap was made of various kinds of rubber chloride, used in the middle of the 20th century it could be heat-sealed.

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 PE cling wrap's tensile strength.
