Abstract

The invention provides a BOPP antibacterial food pearlized film, which comprises an upper antibacterial agent layer, a lower antibacterial agent layer and a middle PP layer positioned between the upper antibacterial agent layer and the lower antibacterial agent layer, wherein the middle PP layer covers on the lower antibacterial agent layer; and the upper antibacterial agent layer covers the middle PP layer. The invention also provides a method for manufacturing the BOPP antibacterial food pearlized film. The BOPP antibacterial food pearlized film has effective bacteriostasis and antibiosis and prolongs the quality guarantee period of products.

Description

technical field [0001] The invention relates to a BOPP antibacterial food pearlescent film and a manufacturing method thereof. Background technique [0002] At present, the domestic food and pharmaceutical industries use ordinary BOPP pearlescent film (biaxially oriented polypropylene pearlescent film) to package products. Pearlescent film packaging products are elegant and luxurious, and are welcomed by consumers, and because of the low cost of pearlescent film, they have become the first choice of enterprises. [0003] However, due to the trace air permeability and water permeability of the BOPP film itself, for products with a shelf life of more than 6 months, it is easy to be corroded by mold and microorganisms, which has great hidden dangers and brings harm to consumers. Contents of the invention [0004] In order to overcome the deficiencies of the existing BOPP pearlescent film in antibacterial and antibacterial properties, the invention provides a BOPP antibacteri...
