Shrink wrap (also referred to as shrink film) is a kind of plastic film that you can wrap on any object, regardless of size or shape. Then heat is applied to the surface, which causes the plastic to shrink. When it shrinks, it conforms to the shape of the object and seals itself. This process results in a clear, durable barrier of protection around the product.
Two Types of Shrink Wrap
Cold molding is the use of adhesive or magnetic plastic film to shape the plastic film and products without heating.
How to Shrink Wrap?
The plastic film can be wound on the product. Seal open ends with a heat sealer. Use a heat gun or heat tunnel to shrink and conform the material to the product.
Different Styles of Shrink Wrap
Tube-Style Shrink Wrap
This shrink film has two pre-sealed sides. People can easily put their products into the tube and specify the appropriate size shrink bag according to the length of the product.
Rolls of Shrink Wrap
Fold the plastic film in half, and then place the product to be sealed in the middle part, and seal the remaining three sides into a bag. Then the film will shrink after heating and tightly wrapping the product inside.
Advantages of Shrink Wrap Protection
When the shrink wrap is heated, it forms a very tight seal. This plastic seal can completely protect the contents of the shrink wrap. After shrink wrapping, the items are no longer susceptible to possible damage from dust, dirt, or moisture. Plastic packaging can protect a book for a long period of time and prevent the inner pages of the book from being oxidized, damp, and dusted. At the same time, it can prevent the book cover from being worn during storage and transportation.
Shrink Wrap vs OPP Bag
OPP is the abbreviation of bopp. OPP bag is stretchable polypropylene, which belongs to plastic. It is actually a plastic bag, which can be seen everywhere in the market and daily life. Most transparent packaging bags are made of OPP materials. This bag is convenient, has a good performance, and it is versatile.
