Stretch film is a type of plastic film that is highly elastic and used for wrapping and securing items. It is commonly made from polyethylene, which allows it to stretch tightly around products, providing protection and stability during storage and transportation. This film is often used in warehouses and shipping industries to bundle pallets and protect goods from dust, moisture, and damage. Its clingy nature helps it stick to itself, ensuring that items remain securely wrapped without the need for additional adhesives or fasteners.
