Abstract

The invention discloses an antibacterial mildew-proof sanitary packaging bag and a preparation process thereof, and belongs to the field of packaging bags. A printing ink layer on the surface of a film body contains an antibacterial agent; the content of the antibacterial agent in the ink layer accounts for 3.0-5.0% of the total weight of the ink layer; and antibacterial and mildew-proof resin particles are contained in the film body. The antibacterial and mildew-proof packaging bag has the beneficial effects that: the three antibacterial and mildew-proof components including the silver ion salt, the zinc ion salt and the copper ion salt are mixed, the zinc ion salt and the copper ion salt are attached to the surfaces of silver ion salt particles, the migration and loss speed of the silver ion salt can be effectively reduced and controlled, and therefore the antibacterial and mildew-proof time of the packaging bag is prolonged.

Description

technical field [0001] The invention relates to the field of packaging bags, in particular to an antibacterial and mildew-proof hygienic packaging bag and a preparation process thereof. Background technique [0002] Most of the films currently used in sanitary products and food packaging have no antibacterial effect. Especially the film used for medicine and food packaging is to achieve various required barrier functions, and generally adopts co-extruded film; while daily hygiene products are only packaged in simple single-layer or multi-layer single non-barrier function and antibacterial film products. . Since there is no packaging film with good antibacterial effect at present, the product is exposed after the bag is opened, which is easy to breed bacteria and deteriorate, and the shelf life is short. [0003] For example, the utility model patent with the notification number CN207607823U discloses a packaging film for antibacterial hygiene products, which includes at le...
