Honeycomb buffer shockproof, moisture-proof and flame-retardant express bag or packaging bag and bag making production line thereof

Abstract

The invention relates to a honeycomb buffer shockproof, moisture-proof and flame-retardant express bag or packaging bag and a paper bag production line thereof. The express bag or packaging bag is formed by folding and adhering composite paper, wherein the composite paper comprises a middle layer, an upper surface layer and a lower surface layer. The express bag or packaging bag is characterized in that the upper surface layer and the lower surface layer are both kraft paper, the middle layer is in a corrugated shape formed by stretching honeycomb paper, and the three layers are connected through glue; the honeycomb paper is flame-retardant paper with a plurality of longitudinal tearing lines and / or cutting marks evenly distributed on the upper face, the longitudinal tearing lines and / or cutting marks are distributed in a matrix mode, and every two adjacent rows of longitudinal tearing lines and / or cutting marks are staggered; and the honeycomb paper is stretched, the longitudinal tearing lines and / or cutting marks are torn open, the flame-retardant paper between every two adjacent tearing lines and / or cutting marks is twisted, and the corrugated shape is formed. The corrugated shape formed by stretching the honeycomb paper is adopted for replacing previous small bubbles, buffer and shockproof functions are achieved, and meanwhile the whole express bag or packaging bag is madeof paper, is easy to degrade and cannot affect the environment.

Description

technical field [0001] The invention relates to a courier bag or packaging bag, in particular to a honeycomb cushioning, shockproof, moisture-proof, flame-retardant courier bag or packaging bag and a bag-making method thereof. Background technique [0002] In the past, courier bags or packaging bags, in order to achieve the purpose of cushioning and shockproof, such as small bubble courier bags, set OPP material between two layers of kraft paper to make small bubbles to form a composite paper, which is folded and glued to form a courier bag In addition, although the small air bubbles between the two layers of kraft paper can play the role of cushioning and shock resistance, the small air bubbles made of this OPP material are not degradable, and discarded express bags are likely to cause environmental pollution. [0003] Patent: CN201920555948.1, Environmentally friendly cushioning packing paper or honeycomb packing paper or mesh kraft paper, which discloses a honeycomb paper...
