Shrink wrap is a type of plastic film that shrinks tightly over an object when heat is applied. It is commonly used for packaging products, protecting them from dust, moisture, and damage during storage and transportation. The film is available in various thicknesses and can be used for both small items and large pallets. The process of using shrink wrap involves placing the item in the film and then applying heat, usually with a heat gun or shrink tunnel. As the film heats up, it contracts and forms a snug fit around the item, creating a secure seal. This method is popular in industries like retail, food packaging, and manufacturing.
