Types of Overwraps

Shrink wrap

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.

Film wrap

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.

Decorative wrap

Paper wrap

Kraft paper and a variety of other papers can be used to overwrap items in a package or to overwrap a package. Some papers provide abrasion protection for packaged items. Sealing can be by adhesive, tapes, heat seals, etc. Some papers also have grease resistance or are saturated with volatile corrosion inhibitors, etc.
