Problems solved by technology

[0002] At present, there are many types of hot pot bottom material packaging bags, such as plastic packaging bags and kraft paper packaging bags. When making kraft paper packaging bags, it is generally necessary to make a composite paper of kraft paper and plastic film, and then cut and press the composite paper On the other hand, the material is fed into the bag making machine for bag making, but in the prior art, when making composite paper packaging bags, it is necessary to unwind the roll, and then use the extrusion mechanism to extrude the melted film to the kraft paper on the extrusion roller, The pair of extrusion rollers will extrude the kraft paper with the melted film, and finally get the required composite paper; but in the above process, because the surface of the kraft paper is relatively smooth, the melted film is easy to fall off during the extrusion process, and the extruded After the mechanism extrudes the molten film once, it will need to stop the unwinding roller for unwinding, and the extrusion mechanism needs to be fed, and the unwinding can only be continued after the feeding is completed, and the efficiency of making composite paper is low

Abstract

The invention relates to the field of packaging bag manufacturing processes, and discloses a production method of a hotpot condiment packaging bag. The method comprises the following steps of A, unwinding; B, tackifying treatment; C, pre-heating treatment; D, composite treatment; E, cooling treatment; and F, bag making. In order to the solve the problems that in the prior art, a fusion thin film is prone to falling off from brown paper, after extrusion by an extrusion mechanism, unwinding needs long-time staying, and the composite paper making efficiency is low, the method is characterized inthat through a corona roller, the surface of the brown paper is subjected to tackifying treatment, through preheating treatment, the surface of the brown paper is more rough, viscosity is further improved, the fusion thin film is easily extruded and formed on the brown paper, the fusion thin film is prevented from falling off from the brown paper, an extrusion cylinder continuously extrudes the brown paper into the fusion thin film, the whole operation does not need to stop unwinding, and thus the composite paper making efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of packaging bag manufacturing technology, in particular to a production method of a hot pot base material packaging bag. Background technique [0002] At present, there are many types of hot pot bottom material packaging bags, such as plastic packaging bags and kraft paper packaging bags. When making kraft paper packaging bags, it is generally necessary to make a composite paper of kraft paper and plastic film, and then cut and press the composite paper On the other hand, the material is fed into the bag making machine for bag making, but in the prior art, when making composite paper packaging bags, it is necessary to unwind the roll, and then use the extrusion mechanism to extrude the melted film to the kraft paper on the extrusion roller, The pair of extrusion rollers will extrude the kraft paper with the melted film, and finally get the required composite paper; but in the above process, because the surface of the...
