Anoverwrap orwrap is a method of sealing a contained product, typically as part of retail packaging. It is often made ofplastic film (sometimes called polywrapping) orpaper.[1] The wrap is applied over the bare product or can be applied over another form ofpackaging. It is typically used to protect products, but can be used decoratively.
An overwrap can be used for several purposes or functions:
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 heldheat gun (electric or gas) or the product and film can pass through aheat tunnel. Mostshrink films arepolyethylene.
Plastic films, usuallypolyethylene orpolypropylene, can be wrapped around an item and attached withadhesive,PSA tape, or heat seals. Sometimes the film is in the form of aplastic bag which is sealed around the item.
Wraps can be either exclusively for visual appeal (decoration) or be protective in nature but encompass a decorative element such as a printed design.
