[0002] The advantages of heat shrink film in the packaging industry are especially applicable to the combined packaging of irregular-shaped items or commodities. Its main function is to stabilize, cover and protect the wrapped items. Heat shrink film has high puncture resistance, good shrinkage and certain shrinkage stress. Especially for packaging irregular-shaped items, it not only has the functions of moisture-proof, dust-proof and anti-touch and substitution, but also can display items transparently, increase the appearance of the goods, and is also used to make packaging bags. It is low-cost and easy to use, and is widely used in life;
