High-strength food packaging film and manufacturing method thereof

The invention relates to a high-strength food packaging film and a manufacturing method thereof. The high-strength food packaging film is characterized by being prepared from, by weight, 200-250 parts of base resin, 22-25 parts of antioxidant, 2.2-3.4 parts of styrol copolymer, 6-9 parts of antioxidant, 2.6-2.8 parts of auxiliary antioxidant, 13-18 parts of heat stabilizer, 13-15 parts of polypropylene, 1-1.5 parts of zeolite, 2.2-3.0 parts of glutaraldehyde, 1.4-2.3 parts of acetic acid, 100-200 parts of LLDPE, 3.4-5.3 parts of stabilizer, 2.8-3.5 parts of pentaerythritol tallate, 3.4-6.3 parts of butadiene, 1.4-2.0 parts of heat stabilizer and 1.4-2.0 parts of antistatic agent. The food packaging film has the advantages that the defects that the own strength of a film is low, and the film cannot be torn easily and is fractured easily when folded are overcome, the hardness of the film is improved, and the film can adapt to environment conditions such as external temperature and humidity and has comprehensive water and gas resisting performance.
