Cling film

Cling film is also known as plastic wrap, food wrap, or saran wrap, is a thin plastic film used for packaging food items in containers for keeping them fresh over a long period of time.

Cling film is a thin transparent plastic film adheres to surfaces and to itself, is used for sealing food items. Cling films are high-quality food wrap films, which prevent food from insects and microbial contamination, dust, keep it fresh, and also minimize the risk of wastage of food by increasing its shelf life.

Cling-wrap plastic films are usually made from polyethylene (PE) or plasticized polyvinyl chloride (PVC), whilst rigid containers are usually made from polystyrene, polyester, or polypropylene.

Polyvinyl chloride (PVC)- and polyethylene (PE)-based cling-films are widely used worldwide for wrapping cheeses. For this purpose, films used in retail possess suitable technical properties such as clinginess and unrolling capacity that are achieved by using specific plasticizers during their manufacturing process. Nowadays, food wrapping provides an attractive presentation and facilitates self-service shopping.

These materials have “stretch” properties and unique “cling,” and hence they are suitable for the hand-wrapping of fresh produce. Such films have high oxygen and water vapour transmission, keeping red meat “red” for longer periods on supermarket shelves. These materials can also be heat-sealed.
