BOPP heat - seal film is a high - performance packaging material, which is made of biaxially oriented polypropylene (BOPP) film through special processing technology. It has excellent transparency, which can clearly display the products in the package and enhance the visual attraction of the products. It has good mechanical properties, including high tensile strength and tear resistance, ensuring that it is not easy to be damaged during the packaging process and transportation. Its heat - seal performance is excellent. Under appropriate temperature and pressure, it can quickly form a firm seal, ensuring the tightness and integrity of the package, effectively blocking the outside air, moisture and dust, and prolonging the shelf life of the products. In addition, the film also has low haze, good slipperiness and antistatic properties, which are convenient for processing and using. It is widely used in the packaging of food, medicine, daily necessities, industrial products and other fields.
