Abstract

The invention discloses a preparation method of novel hot-melt end sealing paper for packaging, and belongs to the technical field of packaging. The preparation method comprises the following steps: by taking cardboard paper or industrial packaging paper as a base material, coating EVA or polyolefin hot melt adhesive on the surface of the base material, and finally airing to obtain the hot-melt head sealing paper. The preparation method of the novel hot-melt head sealing paper for packaging is simple and easy to popularize and apply, and the prepared hot-melt head sealing paper has the characteristics of high strength and good waterproof performance; the defects that the curing time is long, the efficiency is low and volatile substances generated in the curing process hurt workers in the using process of the product in the prior art are overcome; in addition, due to the fact that the hot melting head sealing paper is provided with glue, the labor cost of the using unit is saved.

Description

technical field [0001] The invention belongs to the technical field of packaging, in particular to a method for preparing a novel packaging hot-melt header paper. Background technique [0002] At this stage, the product packaging produced by paper mills mostly uses wrapping paper and plastic composite packaging. With the advancement of technology, the packaging process is replaced by manual packaging to automatic packaging lines. However, the process of pasting the head paper has not been followed by technological innovation, and it is still a continuation of the previous chemical liquid glue. Since the glue is in a liquid shape, it needs to be manually applied and heated to volatilize the chemical components to generate adhesion. Due to the defects of glue properties, it will pollute the environment and cause harm to the human body. Due to the slow curing speed (more than 50 seconds), there are many disadvantages such as low production efficiency. Contents of the inven...
