Problems solved by technology

However, the existing PVC heat-shrinkable film is not environmentally friendly. PET heat-shrinkable film is more widely used now. PET heat-shrinkable film is a new type of heat-shrinkable packaging material, because it is easy to recycle, non-toxic, tasteless, and has mechanical properties Good, especially in line with environmental protection and other characteristics, polyester (PET) has become an ideal substitute for polyvinyl chloride (PVC) heat shrinkable film in developed countries
However, the antistatic properties of PET heat shrinkable films currently on the market are not good.

Abstract

The invention provides an antistatic PET heat shrinkable film, the heat shrinkable film comprises the following raw materials by weight: 80-110 parts of PET resin, 1-5 parts of an additive, 2-5 parts of a lubricant, 1-4 parts of a plasticizer, 2.5-6 parts of an antioxidant and 5-15 parts of an antistatic agent. The PET heat shrinkable film has strong impact resistance, good toughness and excellent antistatic performances.

Description

technical field [0001] The invention relates to a heat-shrinkable film, in particular to an antistatic PET heat-shrinkable film and a preparation method thereof. Background technique [0002] Heat shrinkable film is used for sales and transportation of various products, and its main function is to stabilize, cover and protect products. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. During shrinkage, the film must not develop holes. Among heat shrinkable films, PVC heat shrinkable film, which is widely used, has high strength and large elastic tension. It can tightly wrap products of any geometric shape, and can avoid damage to products caused by bundling. It has good anti-loosening and rainproof properties. , anti-dust, anti-theft and other effects; PVC shrink film is widely used in wine, food, sporting goods, disinfection tableware, electronic appliances, daily necessities, handicrafts, maintenance products, audio-visual p...
