Abstract

The invention discloses a packing bag for preventing mold of grain. The thin film of the packing bag comprises the following ingredients in parts by weight: 100 parts of polyvinyl chloride resin, 15-25 parts of polypropylene resin, 24-26 parts of dioctyl phthalate, 14-18 parts of dioctyl sebacate, 6-8 parts of nano silicon dioxide, 2-4 parts of nano titanium oxide, 4-6 parts of light calcium carbonate, 4-6 parts of activated carbon, 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 grain mold-proof 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 supermarket...
