Abstract

The invention discloses a high-flexible environment-friendly shrink film. The shrink film is prepared from, by weight, 5-15 parts of polypropylene, 15-20 parts of polyethylene, 30-40 parts of linear low-density polyethylene, 1-5 parts of high-density polyethylene, 60-80 parts of thermoplastic starch, 5-10 parts of dibutyl phthalate, 1-5 parts of polyethylene wax, 0.5-1 part of antioxidant 168 and1-2 parts of hydrogenated castor oil. The high-flexible environment-friendly shrink film has the advantages of high transparency, high stretching intensity, high tear resistance, good flexibleness andenvironmental friendliness.

Description

technical field [0001] The invention relates to a highly flexible environment-friendly shrink film. Background technique [0002] During the use of PE film, since the shrink film is widely in contact with air, sunlight, etc., aging and other problems will inevitably occur, and the aging problem will directly affect the service life of the shrink film. In order to avoid the rupture of the shrink film during transportation and use after the beverage is packaged, it is also necessary to improve the high toughness and flexibility of the PE heat shrinkable film. In addition, due to the extensive use of PE shrink film, it has caused environmental pollution. Therefore, while improving the performance of PE shrink film, it is also necessary to improve its environmental performance. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a highly flexible and environment-friendly shrink film with high flexibility, g...
