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 degradable high-toughness packaging film and relates to the technical field packaging films. According to the degradable high-toughness packaging film disclosed by the invention, starch and wool are utilized as main raw materials, then lignocelluloses is added, and varieties of additives are utilized as auxiliary materials; thus, by means of the formula, contents of protein and amino acid are improved; the prepared packaging film has the advantages of high protein, high amino acid, high toughness and stronger physical mechanical property, permselectivity, bacterial resistance and oxidation resistance; furthermore, the chosen raw materials are green, safe and easy to degrade; thus, white pollution is avoided, and ecological environment is protected.

Description

Technical field: [0001] The invention relates to the technical field of packaging films, in particular to a degradable high-toughness packaging film. 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 han...
