The material properties of shrink film directly affect the shrinkage effect. For example, POF film is the mainstream choice due to its high transparency and uniform shrinkage, while PE film is suitable for high-temperature environments.
PE film bags are widely used in food, daily chemical, retail, and industrial packaging due to their softness, toughness, tear resistance, and low cost. High transparency is one of their key advantages—consumers can clearly see the items inside, enhancing
The tear resistance of PE film is one of the core factors contributing to its high reliability in load-bearing applications. This stems not only from the structural advantages of the polyethylene polymer itself but also from its synergistic effect with to
PO film (polypropylene cast film), with its unique high-rigidity molecular structure and excellent mechanical properties, stands out among many flexible packaging materials, becoming a reliable choice for pressure protection.
During the stretch molding process, high melt index PE film, due to its excellent fluidity, can quickly fill the mold cavity, reducing processing time and energy consumption.
Plastic shrink film, as a key material in modern packaging systems, is widely used in the sales and logistics of industries such as food, beverages, daily chemicals, and electronics.
