Problems solved by technology

However, in today's increasingly serious "white pollution", conventional plastic wraps are not easy to decompose in the environment due to their poor degradability, resulting in poor environmental performance. Higher, less fresh-keeping film prepared by new raw materials and new processes, etc.
[0003] In addition, the existing plastic wrap only isolates the vegetables, fruits and other foods inside it from the outside air, and if the fruits and vegetables inside are kept fresh, if the ethanol produced when the vegetables are ripe is not decomposed and released, it will accelerate the decomposing of the fruits and vegetables. Mature or even spoiled, fruits, vegetables, cooked food and other foods put in the plastic wrap at the same time, bacteria, mold, etc. have been stuck to the plastic wrap before they are put in the plastic wrap, and they can continue to multiply in the plastic wrap, which accelerates the spoilage of the food

Abstract

The invention discloses a preservative film with bacteriostatic and antiseptic functions and a preparation method thereof. The preservative film with bacteriostatic and antiseptic functions comprises the following components in parts by weight: 100 parts of polypropylene, 5-10 parts of gelatin, 2-5 parts of corn fiber, 1-5 parts of glycerol, 0.5-2 parts of a coupling agent, 0.5-2 parts of a mildew preventive, 2-6 parts of a bacteriostatic agent, 3-7 parts of a modifier, 2-5 parts of a flexibilizer and 0.5-3 parts of an antioxidant. The preservative film has excellent antibacterial preservative fresh-keeping performance for food packaging, is non-toxic, odorless and free of contact corrosion, can effectively prolong a storage period and presents excellent tensile strength and the softness; and meanwhile, the raw materials adopted by preservative film are safe, reliable, green and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping film materials, in particular to a fresh-keeping film with antibacterial and antiseptic functions and a preparation method thereof. Background technique [0002] Preservative film usually has moderate oxygen permeability and moisture impermeability, which can adjust the oxygen content and moisture content around the fresh-keeping products, block the dust in the air, and prolong the fresh-keeping period of food. However, in today's increasingly serious "white pollution", conventional plastic wraps are not easy to decompose in the environment due to their poor degradability, resulting in poor environmental performance. Higher, fewer plastic wraps prepared by new raw materials and new processes. [0003] In addition, the existing plastic wrap only isolates the vegetables, fruits and other foods inside it from the outside air, and if the fruits and vegetables inside are kept fresh, if the ethan...
