Introduction to Shrink Wrap

Shrink wrap is a low density polyethylene film made from fractional melt resin and other additives. Protective Products Shrink Wrap is available in a variety of widths, lengths, thicknesses and colors to meet a variety of needs.

Heat shrink films for packaging are films belonging to a class of plastics known as thermoplastic. They soften and melt when heated. The long polymer molecules in heat shrink films are in a tangled up configuration. When the film is made, it is stretched while hot, which lengthens the molecules. They stay frozen when the film is cooled. Again, when enough heat is applied, they freely move and go back to the tangled state, and thus get shorter, shrinking the film. 

Shrink-wrapping is a simple, attractive and inexpensive packaging solution. It displays and protects the product, is clean and tamper evident. Shrink-wrapping is an investment in the appearance and appeal of any product.
