Abstract

The invention discloses a production process of a paper packaging bag, which comprises an inner packaging base paper layer, a barrier adhesive layer and an outer packaging base paper layer; the inner packaging base paper layer and the outer packaging base paper layer are bonded by the barrier adhesive of the barrier adhesive connected, and hot-pressed to form an integrated paper packaging bag. The packaging bag of the present invention is formed by thermal pressing of the inner packaging base paper layer, the barrier glued layer and the outer packaging base paper layer. Packaging base paper layer.

Description

technical field [0001] The invention relates to the technical field of paper packaging bags, in particular to a production process of paper packaging bags. Background technique [0002] Paper packaging has the advantages of easy processing, low cost, suitable for printing, light weight, foldable, non-toxic, tasteless, and pollution-free, but it has poor water resistance and poor strength when wet. Paper packaging materials can be divided into two categories: packaging paper and cardboard. General packaging paper is collectively referred to as paper packaging. The performance requirements of paper packaging mainly include the following aspects: high strength, low cost, good air permeability, and wear-resistant packaging are mostly used as shopping bags and document bags, such as kraft paper. Wrapping paper with smooth paper surface and high strength is mostly used as labels, clothing tags, bottle stickers, such as bleached paper. Supported by natural raw materials, non-toxi...
