Problems solved by technology

[0003] The existing common anti-static packaging bags, the anti-static masterbatch is mainly composed of polypropylene and low-melting point ethoxylated alkylamines, and the low-melting point ethoxylated alkylamine antistatic agent is characterized by being soluble in Water, so in the drawing process of the manufacturing process, the antistatic agent has been partially dissolved in water, thereby reducing the antistatic performance
At the same time, during the use of the packaging bag, the antistatic agent will continue to precipitate, and the antistatic ability will weaken until it disappears.

Abstract

The invention relates to a durable antistatic anti-explosion packing bag which comprises the following components: PP, a color masterbatch, an antistatic functional masterbatch, an antiaging agent and a calcium carbonate filling masterbatch. A preparation method for the durable antistatic anti-explosion packing bag comprises the steps of wiredrawing, circular knitting, film coating, cutting and sewing. The packing bag produced by the invention is good in antistatic and anti-explosion effects, a metal antistatic agent cannot be separated out and is insoluble in water, and the durability of the antistatic ability is good.

Description

technical field [0001] The invention relates to a packaging bag and a preparation method thereof, in particular to an antistatic explosion-proof packaging bag and a preparation method thereof. Background technique [0002] Packaging bag, also known as container bag, is a kind of flexible transportation packaging container, which is widely used in the transportation packaging of food, grain, medicine, chemical industry, mineral products and other powdery, granular and lumpy items. [0003] The existing common anti-static packaging bags, the anti-static masterbatch is mainly composed of polypropylene and low-melting point ethoxylated alkylamines, and the low-melting point ethoxylated alkylamine antistatic agent is characterized by being soluble in Water, so in the wire drawing process of the manufacturing process, the antistatic agent has been partially dissolved in water, thereby reducing the antistatic performance. At the same time, during the use of the packaging bag, the ...
