Problems solved by technology

[0005] In the prior art, there have been some reports about antibacterial plastic wraps for fruits and vegetables, but there have been no reports about antibacterial packaging bags for grains. Because the fresh-keeping requirements of grains and fruits and vegetables are different, the fresh-keeping bags used for fruits and vegetables cannot be directly used for food. Preservation, at the same time, the antibacterial plastic wraps used for fruits and vegetables in the prior art all use nano-silver for antibacterial, but silver is a precious metal, and its cost is relatively high, so it is used for plastic wrap or fresh-keeping bags, causing great waste

Embodiment 1

[0012] An antibacterial packaging bag for food, the film is composed of the following components in parts by weight: 60 parts of polyvinyl chloride resin, 20 parts of polyethylene resin, 18 parts of dioctyl phthalate, and 32 parts of polytrimethylene adipate , 2 parts of organically modified nano-calcium carbonate, 4 parts of modified copper sulfate, 3 parts of octadecyl ammonium chloride, 6 parts of calcium-zinc composite stabilizer, 2 parts of stearic acid, 2.5 parts of liquid paraffin; The preparation method of nano-calcium carbonate is as follows: first preheat and dry the inorganic nano-calcium carbonate at 120° C. for 2 hours to remove moisture; Fully stir and disperse, after 35 minutes of treatment, vacuum dry to remove the solvent to obtain organically modified nano-calcium carbonate; the preparation method of modified copper sulfate is: first mix copper sulfate and silane coupling agent at a ratio of 1:1, and dry at 120°C Modified treatment.

Embodiment 2

[0014] An antibacterial packaging bag for food, the film is composed of the following components in parts by weight: 80 parts of polyvinyl chloride resin, 10 parts of polyethylene resin, 22 parts of dioctyl phthalate, and 28 parts of polytrimethylene adipate , 5 parts of organically modified nano-calcium carbonate, 2 parts of modified copper sulfate, 5 parts of octadecyl ammonium chloride, 4 parts of calcium-zinc composite stabilizer, 4 parts of stearic acid, 1.5 parts of liquid paraffin; The preparation method of nano-calcium carbonate is as follows: first preheat and dry the inorganic nano-calcium carbonate at 140° C. for 1 hour to remove moisture; Fully stir and disperse, after 45 minutes of treatment, vacuum dry to remove the solvent to obtain organically modified nano-calcium carbonate; the preparation method of modified copper sulfate is: first mix copper sulfate and silane coupling agent at a ratio of 1:1, and dry at 140°C Modified treatment.

Embodiment 3

[0016] An antibacterial packaging bag for food, the film is composed of the following components in parts by weight: 70 parts of polyvinyl chloride resin, 15 parts of polyethylene resin, 20 parts of dioctyl phthalate, and 30 parts of polytrimethylene adipate , 4 parts of organically modified nano-calcium carbonate, 3 parts of modified copper sulfate, 4 parts of octadecyl ammonium chloride, 5 parts of calcium-zinc composite stabilizer, 3 parts of stearic acid, and 2 parts of liquid paraffin; The preparation method of nano-calcium carbonate is as follows: first preheat and dry the inorganic nano-calcium carbonate at 130° C. for 1.5 hours to remove moisture; Thoroughly stir and disperse, after 40 minutes of treatment, vacuum-dry to remove the solvent to obtain organically modified nano-calcium carbonate; the preparation method of modified copper sulfate is: first mix copper sulfate and silane coupling agent at 1:1, and dry at 130°C Modified treatment.

Abstract

The invention discloses an antimicrobial packing bag for grains. The thin film of the packing bag comprises the following ingredients in parts by weight: 60-80 parts of polyvinyl chloride resin, 10-20 parts of polypropylene resin, 18-22 parts of dioctyl phthalate, 28-32 parts of polypropylene glycol adipate, 2-5 parts of organic modified nano calcium carbonate, 2-4 parts of modified copper sulfate, 3-5 parts of octadecyl ammonium chloride, 4-6 parts of a calcium-zinc composite stabilizer, 2-4 parts of stearic acid, and 1.5-2.5 parts of liquid paraffin.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a food antibacterial packaging bag. Background technique [0002] Fresh-keeping bags are a kind of plastic packaging products commonly used by people to keep fresh food, and now many families cannot do without them. Microwave food heating will be used, and food storage in the refrigerator will also be used. People use fresh-keeping bags mainly to prevent dust and bacteria from corroding food. [0003] Most of the fresh-keeping bags currently on the market are the same as the commonly used plastic bags. They are made of vinyl masterbatch. According to the different types of vinyl masterbatch, the fresh-keeping bags can be divided into three categories: the first is polyethylene, Referred to as PE, this material is mainly used for food packaging. This film is used for fruits and vegetables that are usually bought, including semi-finished products purchased in supermark...
