Embodiment 1

[0029] refer to figure 1 , a BOPP antibacterial food pearlescent film, the BOPP antibacterial food pearlescent film includes an upper antibacterial agent layer 1, a lower antibacterial agent layer 3 and an intermediate PP layer 2 between the upper antibacterial agent layer and the lower antibacterial agent layer; The middle PP layer 2 is covered on the lower antibacterial agent layer 3, and the upper antibacterial agent layer 1 is covered on the middle PP layer 2;

[0030] In the BOPP antibacterial food pearlescent film, the mass content of the upper antibacterial agent layer 1 and the lower antibacterial agent layer 3 is independently 3%, and the middle PP layer 2 is 94%;

[0031] Both the upper antibacterial agent layer and the lower antibacterial agent layer include PP material, nano calcium carbonate and antibacterial agent, and the mass percentages of the three components in the total mass are: 66% of PP material, 26% of nano calcium carbonate, and 8% of antibacterial ag...

Embodiment 2

[0037] refer to figure 1 , in the present embodiment, in the BOPP antibacterial food pearlescent film, the mass content of the upper antibacterial agent layer and the lower antibacterial agent layer are independently 4%, and the middle PP layer is 92%;

[0038] Both the upper antibacterial agent layer and the lower antibacterial agent layer include PP material, nano calcium carbonate and antibacterial agent, and the mass percentages of the three components in the total mass are: 70% of PP material, 23% of nano calcium carbonate, and 7% of antibacterial agent %;

[0039] The middle PP layer includes PP material, pearlescent masterbatch and nano-calcium carbonate, and the mass percentages of the three components in the total mass are: PP material 63%, pearlescent masterbatch 12%, and nano-calcium carbonate 25%.

[0040] Other structures and working processes of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0042] refer to figure 1 , in the present embodiment, in the BOPP antibacterial food pearlescent film, the mass content of the upper antibacterial agent layer and the lower antibacterial agent layer are independently 4.5%, and the middle PP layer is 91%;

[0043] Both the upper antibacterial agent layer and the lower antibacterial agent layer include PP material, nano calcium carbonate and antibacterial agent, and the mass percentages of the three components in the total mass are: PP material 72%, nano calcium carbonate 22%, antibacterial agent 6 %;

[0044] Described middle PP layer comprises PP material, pearlescent masterbatch and nano-calcium carbonate, and the mass percent that three components account for total mass is: PP material 65%, pearlescent masterbatch 10%, nano-calcium carbonate 25%.

[0045] Other structures and working processes of this embodiment are the same as those of Embodiment 1.

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 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 antibacterial food pearlesc...
