What additives can be added to PE heat shrinkable film to enhance its performance?

2024-04-10 Industry News
PE heat shrinkable film can add the following additives to enhance performance:

Antioxidants: Adding antioxidants to PE heat shrinkable film can effectively prevent oxidation reactions caused by oxygen. These reactions may lead to the breakage of polyethylene molecular chains and the reduction of physical properties, thereby affecting the service life and stability of the membrane. Commonly used antioxidants include calcium stearate, benzotriazoles, etc.

Ultraviolet absorber: Adding ultraviolet absorber to the PE heat shrinkable film can absorb or scatter ultraviolet radiation and prevent ultraviolet damage to the polyethylene material. This helps extend the life of the film and maintains its optical clarity and physical strength. Commonly used UV absorbers include benzotriazoles, benzodiphenols, etc.

Antistatic agent: Adding antistatic agent to PE heat shrinkable film can reduce the generation of static electricity on the film surface, reduce dust adsorption and prevent electrostatic adhesion of products during the packaging process. This helps improve packaging efficiency and product quality. Commonly used antistatic agents include phenolic acids, amino lipids, etc.

Fillers: Adding fillers can improve the physical properties of PE heat shrinkable film, reduce costs and improve processing performance. Commonly used fillers include silicates, calcium carbonate, talc, etc., which can increase the strength, stiffness and wear resistance of the membrane.

Modifier: Modifier can improve the flexibility, stretchability and wear resistance of PE heat shrinkable film, and improve its applicability and service life. Commonly used modifiers include acrylate copolymers, polyamides, etc., which can change the structure and performance characteristics of the membrane to meet different application needs.

Pigments and colorants: Adding pigments and colorants can make the PE heat shrinkable film have rich color choices, increasing its aesthetics and recognition in product packaging. Commonly used pigments and colorants include organic pigments, inorganic pigments, pigment dispersants, etc. Their formulas can be adjusted according to customer needs to achieve customization of various colors.
