High-strength packaging bag material

Abstract

The invention discloses a high-strength packaging bag material which comprises a surface sun shading layer, a middle base body layer and a back face waterproof layer. The surface sun shading layer is arranged on the upper surface of the middle base body layer, the back face waterproof layer is arranged on the lower surface of the middle base body layer, the surface sun shading layer is an opaque plastic thin film, the back face waterproof layer is an opaque plastic thin film, the middle base body layer is made of ultra-thin high-strength fabrics, and the ultra-thin high-strength fabrics are formed by blending polynosic and high-strength and high-modulus polyethylene fibers. By means of the mode, the high-strength packaging bag material is formed by compositing three layers of materials, durability is good, especially, the strength of the middle base body layer is high, the high-strength packaging bag material is resistant to tearing and puncturing, the service life is long, and the high-strength packaging bag material can be repeatedly used and is wide in application range.

Description

technical field [0001] The invention relates to the field of material design of packaging bags, in particular to a high-strength packaging bag material. Background technique [0002] The materials of packaging bags are mainly divided into packaging cloth bags, packaging paper bags and plastic packaging bags. Packaging bags are widely used, and packaging and transportation of small products need to use packaging bags. Due to the late appearance of plastic, people used to use cloth bags and paper bags before, and with the invention and continuous improvement of plastic, the application of plastic packaging bags continues to grow. [0003] Due to poor water resistance of cloth bags and paper bags, high cost and complicated packaging process, the market is shrinking. Plastic paper has excellent waterproof performance, cheap price, and simple production and packaging processes. However, due to its thin thickness and poor strength, ordinary plastic paper has the problems of bein...

Problems solved by technology

[0003] Due to the poor waterproof performance of cloth bags and paper bags, and the high cost and complicated packaging process, the market continues to shrink

Plastic paper has excellent waterproof performance, cheap price, and simple production and packaging process. However, due to the thin thickness and poor strength of ordinary plastic paper, it is easy to be punctured by hard objects, low reuse rate, poor durability and low bearing capacity.
