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 can

Example Embodiment

[0008] An example is given below.

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

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...
