Problems solved by technology

In the early 1990s, a kind of polymer coating film structure packaging bag containing insecticides coated on the outer surface of ordinary plastic woven bags appeared in China. The insecticides in the film were slowly released to prevent and kill insects. The insecticide ingredients in the coating can only prevent and kill insects, but cannot inhibit the growth and elimination of grain molds, which is still not conducive to the preservation of grain
In recent years, an inner plastic bag made of polyethylene, surface roughening agent and insect-proof and mildew-proof agent raw materials has come out. Mold ingredients, the production process is complicated and the cost is high

Embodiment Construction

[0008] Examples are given below.

[0009] The coating film material coated on the outer surface of the plastic woven bag includes 3% zinc oxide whisker nanocomposite material masterbatch and 97% polyethylene (PE) or polypropylene (PP) material masterbatch, Weigh it for later use; mix all the powdered zinc oxide whisker nanocomposite masterbatches with polyethylene or polypropylene material masterbatches, and mix them evenly in a mixer; send the evenly mixed materials into the coating machine, It melts into a liquid state at a high temperature of 210-250 ° C; the liquid mixed material is cast on the surface of the plastic woven cloth through the die head of the screw extruder to form a film layer; the color printing machine prints the color packaging pattern of the packaging bag on the On the coating layer; the punching machine punches micro-shaped ventilation holes on the coating layer; the plastic woven cloth is cut and sewn into finished grain packaging bags by cutting and s...

Abstract

An antibacterial packing bag for grains is prepared through proportionally mixing zinc oxide crystal whisker with polyethene or polypropene, high-temp fusing, coating it on the surface of the braided plastic fabric, printing color pattern, punching to form air pinholes, cutting and sewing. Its advantage is high antimildew and antibacterial effect.

Description

technical field [0001] The invention belongs to a woven bag packaging product and product processing technology, and mainly relates to a food antibacterial packaging product and a manufacturing process. Background technique [0002] At present, ordinary plastic woven bags are mostly used as packaging products in China. In order to prevent rice leakage, the outer surface of ordinary plastic woven bags is coated with a layer of polyethylene or polypropylene coating film. This type of woven bag does not have insecticidal and sterilizing properties, which reduces the shelf life of rice. In the early 1990s, a kind of polymer coating film structure packaging bag containing insecticides coated on the outer surface of ordinary plastic woven bags appeared in China. The insecticides in the film were slowly released to prevent and kill insects. Effect, the insecticide composition in this coating can only prevent and kill insects, can not inhibit the growth and elimination of grain mol...
