Abstract

The invention discloses a multi-layer composite packaging bag and a processing technology thereof. The multi-layer composite packaging bag comprises a bag body, wherein the bag body is divided into five layers which are mutually attached to each other, the innermost layer is an anti-tear layer, the tear-resistant layer is a nylon fiber layer, the thickness of the nylon fiber layer is 3 mm, the nylon fiber layer is composed of warp nylon fibers and weft nylon fibers, every three warp nylon fibers are twisted with one another, every three weft nylon fibers are twisted with one another, the two outer layers are flame retardant layers, and the two intermediate layers are heat insulation layers. According to the multi-layer composite packaging bag, the nylon fiber layer, the flame retardant layers and the heat insulation layers are arranged, the multi-layer composite packaging bag has good tear resistance and high temperature resistance.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a multilayer composite packaging bag and its processing technology. Background technique [0002] Packaging bag refers to the bag used to pack various supplies, so that the goods are conveniently transported and stored during the production and circulation process, and are widely used in daily life and industrial production. With the development of the times, the commercial nature of the packaging bag itself is becoming more and more It has become more and more obvious that it has become a special product that is no longer attached to commodity production, a product that is inseparable from all commodities and is widely used. In the chemical industry, packaging is required for the handling and delivery of chemicals When bags and packaging bags are used in the chemical field, due to the characteristics of chemical products, it is inevitable that the packaging bags will be torn a...
