Description

technical field

[0001] The invention belongs to the technical field of fresh-keeping film, and in particular relates to a polyethylene antibacterial film and its preparation method and application. Background technique

[0002] PE is polyethylene. Polyethylene is the thermoplastic material with the largest output in plastics, and it is also the plastic variety with the largest amount at present. It has also played an important role in the field of food packaging in recent years. PE film itself has no antibacterial properties, and antimicrobial agents can be incorporated into PE films. However, the preparation of PE films by this method will be limited by the thermal stability of antimicrobial agents or incompatibility with polymers during extrusion. It is a better choice to modify the surface of PE film and then use coating technology. The common method of surface modification is plasma surface treatment. The effect of corona treatment is the same as that of plasma treatmen...
