NOVELTY - Environmentally friendly soybean protein based plastic packaging film comprises 40-49 pts. wt. soybean protein, 10-15 pts. wt. potato starch, 3-8 pts. wt. magnesium stearate, 3-6 pts. wt. soybean straw fiber, 3-7 pts. wt. antistatic agent, 2-5 pts. wt. ceramic fiber, 1-3 pts. wt. activated graphene, 2-4 pts. wt. flame retardant, 4-6 pts. wt. xanthan gum, 13-13 pts. wt. porous carbon, 2-3 pts. wt. coupling agent, 2-5 pts. wt. lauric acid, 2-3 pts. wt. toughening agent, 1-3 pts. wt. modified poly- beta -hydroxybutyric acid, 1-4 pts. wt. natural antibacterial agent, 1-3 pts. wt. microbial nutritional additive and 3-6 pts. wt. turpentine. USE - Used as environmentally friendly soybean protein based plastic packaging film. ADVANTAGE - The plastic packaging film: has improved wear resistance and tear resistance; and can be degraded into carbon dioxide and water by microorganisms after being discarded and reused by nature; and does not cause irreversible damage to environment.
