Overwrap

An Overwrap or wrap is applied over an item in a package or is applied over another form of packaging. It is often made of plastic film (sometimes called Polywrapping) or paper. Shrink wrap is a material made up of polymer plastic film. When heat is applied it shrinks tightly over whatever it is covering. Heat can be applied with a hand held heat gun (electric or gas) or the product and film can pass through a heat tunnel. Most shrink films are polyethylene. Films, usually polyethylene or polypropylene, can be wrapped around an item and attached with adhesive, PSA tape, or heat seals. Sometimes the film is in the form of a plastic bag which is sealed around the item. Kraft paper and a variety of other papers can be used to overwrap items in a package or to overwrap a package....
