Abstract

The invention relates to antibacterial fresh-keeping plastic film and a manufacturing method thereof. According to the preparation method, an inorganic nano antibacterial material is diffused in a film base material, so that antibacterial and mildew-proof effects are achieved. The manufacturing method comprises the following steps: preparing an inorganic nano-antibacterial solution from a nano-granular inorganic nano-antibacterial material; in a high-pressure and high-temperature reaction kettle, pumping air in plastic out, carrying out primary heating for preheating, carrying out high-pressure and sufficient heating to enable the inorganic nano-antibacterial solution to be completely diffused into a plastic raw material; then, further carrying out pressure reduction to separate residual materials and impurities. According to the manufacturing method, the nano-granular inorganic nano-antibacterial material is uniformly diffused into the plastic, so that the plastic particles have antibacterial function, and then film blowing, plastic uptake or casting molding is carried out to prepare the plastic film; and the problem that existing plastic does not have an antibacterial function issolved.

Description

technical field [0001] The invention belongs to the field of antibacterial technology, and in particular relates to an antibacterial fresh-keeping plastic film and a manufacturing method thereof. Background technique [0002] Plastic film, often used in food preservation packaging or item storage. For example, in order to meet the needs of fresh-keeping in the kitchen, in the prior art, fresh-keeping film is often used to seal dishes, or fresh-keeping vacuum bags are used for storage; in medical and other fields, plastic film bags are often used to store waste items. [0003] However, the existing plastic films and their finished products have relatively simple functions and only have the function of storage or sealing, and their use environment is generally relatively airtight, with high humidity, and bacteria will exist in large numbers in relatively airtight or poorly ventilated places. , The surface of the plastic film is also easy to breed bacteria and affect the use a...
