Abstract

The invention provides a low-temperature shrink film. The low-temperature shrink film comprises PE (polyethylene) layers in the middle and PP (polypropylene) layers on upper and lower surface layers and is prepared from raw materials in parts by weight as follows: 50-80 parts of PE and 20-40 parts of PP. Raw materials of each of the three PE layers comprise LLDPE (linear low density polyethylene) 2045G, LLDPE 4203 and LLDPE OF07. The low-temperature shrink film adopts three PE layers in the middle and two PP layers on surfaces, each PE layer is formed through press fit of films made of three materials, the PP layer material on the surfaces contains a lubricant, and the low-temperature shrink film has excellent low-temperature shrink effect.
