Cling film is defined as “the thin plastic film typically used for sealing food items in containers to keep them fresh over a longer period of time.” Cling film was initially produced from a material known as polyvinyl chloride (PVC). PVC is used because it allows permeability to water vapor and oxygen transfer, which can be used to add to the freshness of the food products wrapped. Though there have been recent concerns about the transfer of plastic from PVC into food.
In recent times, a common alternative to PVC is that is being used in large scale is low-density polyethylene (LDPE). It has less adhesive properties than PVC, but that feature can be rectified by adding linear low-density polyethylene (LLDPE), which also helps to increase the film’s tensile strength. In the US and Japan, cling film is sometimes produced using polyvinylidene chloride (PVdC), though other alternatives are being sought to several environmental concerns regarding PVDC.
