Shrink-wrap is one of the most popular forms of packaging, and usually one of the most inexpensive forms of packaging. Shrink wrap protects the product. Shrink-wrap is used for making multi-packs such as commonly found in Sam's, Costco, and most major retailers. Shrink wrap increases the shelf appeal of the product. Shrink-wrap helps in reducing pilferage, especially if you use heavy gauge film. Shrink-wrapping is a very simple process where a closed bag is formed around the product the product, typically using a sealer, then the enclosed product is subjected to heat, typically using a heat tunnel, which shrinks the plastic shrink film around the product.
