PE heat shrink film, also known as polyethylene heat shrink film, is a type of plastic film that is used for packaging and wrapping products. It is made from polyethylene, a thermoplastic material that becomes soft and pliable when heated and then shrinks tightly around the item it is covering as it cools.
PE heat shrink film is commonly used in various industries, including food and beverage, pharmaceuticals, electronics, and retail. It provides protection and tamper-evident packaging for products, ensuring their integrity during transportation and storage.
The film is typically applied using heat shrink machines or heat guns, which apply heat to the film, causing it to shrink and conform to the shape of the product. The film has excellent clarity, allowing for easy visibility of the packaged item, and it can be printed on for branding and labeling purposes.
