PE heat shrinkable film is suitable for the whole package of wine, cans, mineral water, various beverages and other products. The product has good flexibility, strong impact and tear resistance, not easy to damage, not afraid of moisture and high shrinkage.

The existing PE heat shrinkable film has limitations in strength and toughness, and HDPE is generally used to improve the degree. For example, the prior art cn101049749a discloses a highly transparent multilayer polyethylene heat shrinkable film, which is a three-layer structure, in which the upper and lower layers are a mixture composed of metallocene m-LLDPE, LLDPE, LDPE and additives, and the middle layer is a mixture composed of LDPE, LLDPE and HDPE. However, HDPE will greatly reduce the toughness of PE heat shrinkable film, and it is easy to break during transportation after beverage packaging. Therefore, how to improve the tensile and toughness of PE heat shrinkable film has become an urgent problem to be solved. PE heat shrinkable film shows that polyethylene is the main component of the shrinkable film. Polyethylene is a compound polymerized by many ethylene monomers. It is tasteless and widely used in food and drug packaging plastics. Polyethylene has the characteristics of stable chemical properties, not easy to aging, easy degradation and no reaction with general oxidants.

Silica can be evenly added to the PE shrink film formula, which can increase the compactness and finish of the shrink film. On the other hand, it can also enhance the toughness of the shrink film and change the tensile strength of the shrink film. Silica also has the effect of anti ultraviolet rays, which can prevent the degradation of polyethylene by ultraviolet rays and delay the aging of shrinkage film. PE heat shrinkable film inspection found that the main non-ionic antistatic agent is ethoxylated aliphatic alkyl amine, which is an antistatic agent with wide application range and can maintain the antistatic effect for a long time. Non ionic antistatic agent has the advantages of good dispersion, convenient transportation and good processing performance. The anti ultraviolet agent in PE shrink film formula is mainly to convert light energy into heat energy to avoid the degradation of plastics under ultraviolet irradiation. The commonly used ultraviolet absorbers are benzophenone and benzotriazole.

At present, Hangzhou Chaohong plastic packaging Co., Ltd. mainly takes PVC heat shrinkable film, PE heat shrinkable film, POF heat shrinkable film, pet heat shrinkable film, PE winding film and other products as the leading products to provide services for customers. Introduce advanced equipment, adopt * * Brand raw materials, absorb the technical advantages of peers at home and abroad, constantly innovate and explore, and the product quality is reliable. It is widely used in trademark printing in beverage, condiment, battery, washing cosmetics and other industries. It has perfect production line equipment of PVC heat shrinkable printing film. The products are excellent for several * * enterprises in China and have been highly praised by the majority of customers.
