Problems solved by technology

The existing way of endowing food packaging film with antibacterial function is mainly to apply or spray antibacterial agent on the surface of the packaging film after the film is formed, and then dry it to obtain it. Potential safety hazards, and traditional disinfectants or antibacterial agents are somewhat toxic, limiting their application in food packaging

Abstract

The invention relates to the field of food packaging, in particular to a food packaging material capable of keeping fresh and resisting bacteria for a long time. The invention discloses a food packaging material capable of keeping fresh for a long time and resisting bacteria. the material is prepared from the following specific components in parts by weight: 10 to 80 parts of polylactic acid, 10 to 50 parts of polycaprolactone, 10 to 30 parts of polymethyl ethylene carbonate, 5 to 20 parts of chitosan, 1 to 8 parts of gelatin, 0.1 to 1 part of fennel leaf extract, 0.5 to 3 parts of Ti powder,0.1 to 2 parts of AlCl3 particles and 1 to 5 parts of a plasticizer. According to the invention, the problem that the application of the traditional disinfectant or antibacterial agent in food packaging is limited due to certain toxicity is solved. The food packaging material disclosed by the invention not only has good fresh-keeping and antibacterial effects, but also has excellent mechanical properties, and is an environment-friendly product which is non-toxic to human bodies and is environment-friendly.

Description

Technical field [0001] The invention relates to the field of food packaging, in particular to a food packaging material capable of long-term preservation and antibacterial. Background technique [0002] The current era is an era of unprecedented prosperity for the commodity economy in Chinese history, and it is also a period of rapid development of Chinese food packaging design. The economic prosperity and the rapid growth of packaging products are at the high price of the extreme misuse of the country's natural resources and severe damage to the ecological environment. Food packaging accounts for the largest share of packaging waste, and the most commonly used material for food packaging is plastic. Many foods do not use green packaging materials, but use some toxic and harmful substances as packaging materials. Their safety will directly affect the food quality. Unqualified food packaging will have adverse effects on human health during use, especially The healthy development...
