The invention provides a PHA material degradable plastic film and a production process thereof, belonging to the technical field of the plastic film field, and comprising the following components in parts by weight: 90-100 parts of PHA resin, 20-40 parts of PBAT resin, and inorganic additive masterbatch 15-30 parts, modified starch 2-5 parts, glycerin 1-5 parts, polylactide 1-5 parts, heat stabilizer 0.8-1.5 parts, compound antioxidant 0.5-2 parts, antistatic agent 0.2- 0.5 servings. The beneficial effects of the present invention are that the plastic film can have better thermal stability during use, the service life can be longer, and it is less affected by temperature at a certain temperature, and the service life of the plastic film can be improved. The role of antioxidants is to capture active free radicals and interrupt the chain reaction. The purpose is to delay the oxidation process and speed of plastics, and blow plastics into films of the desired thickness. By preheating and heating, the plastic molding effect can be better. , and the fluidity of the material in the equipment is better, and the quality of the formed plastic film is better. |
