Problems solved by technology

On the one hand, these packaging films have the disadvantage of being difficult to degrade or take a long time to degrade, which is easy to cause white pollution and affect the environment; on the other hand, these packaging films have poor air permeability. If the oxygen concentration in the packaging film is too low or If the concentration of carbon dioxide is too high, the fruit will undergo anaerobic respiration, resulting in the accumulation of volatile substances such as ethanol and acetaldehyde, resulting in peculiar smell and smell, and reducing the flavor quality of the fruit

Abstract

The invention discloses a food-packaging film with a preservation effect, which relates to the technical field of packaging films. According to the invention, with alga and bamboo as main materials, starch is then added, supplemented by various additives, so that the produced packaging film has high preserving property as well as high physical and mechanical properties and antibacterial and antioxidation effects. Moreover, the chosen materials are green, safe and easy to degrade, consequently, white pollution is prevented, and the ecological environment is protected.

Description

Technical field: [0001] The invention relates to the technical field of packaging films, in particular to a food packaging film with antiseptic effect. Background technique: [0002] Plastic film packaging is currently the most widely used packaging material for fresh fruit and vegetable production. It is transparent, so you can clearly see the condition of the packaged products; it has moisturizing properties, which can reduce the moisture loss of products and increase the freshness; It is airtight to protect the product from contamination. [0003] At present, the food packaging films used in China are generally based on polymers such as polyethylene, polypropylene, and polyvinyl chloride, and are made by mixing plasticizers, inorganic fillers, and antibacterial agents. On the one hand, these packaging films have the disadvantage of being difficult to degrade or take a long time to degrade, which is easy to cause white pollution and affect the environment; on the other h...
