Shrink film is a type of plastic film that shrinks tightly over an object when heat is applied. It is commonly made from materials like polyethylene or polyolefin and is used for packaging products to protect them from dust, moisture, and damage. The film is often used in commercial settings for bundling items or creating tamper-evident packaging. When heated, shrink film conforms to the shape of the item it covers, providing a secure fit. This makes it popular for packaging food, electronics, and other consumer goods. The versatility and durability of shrink film make it an essential tool in various industries.
