Analysis of Common Problems of Mounting Printing Paper in Cosmetic Paper Bag Making
Everyone must have a little knowledge about the production and printing of cosmetic paper bags. In the production process, there is a process called mounting, which refers to a thin coated paper, special paper or double-adhesive paper. After printing, the two sheets are glued together. So what are the common problems in the mounting process? Today, I will explain it to you one by one.
1. The paper is warped
The reason for this phenomenon is mainly because too many sheets are pasted, so that the glue on the edge of the cardboard is dry and cannot stick. Therefore, it is usually pressed and compared after 20 sheets are pasted, so that the glue is fixed and the cardboard is flat.
2. The humidity of the paper is too high
Special attention should be paid to the mounting of gold and silver cardboard, because the gold and silver cardboard has poor water penetration and dissipation ability. It can be solved by taking quick-drying glue or placing the product in the sun to dry.
3. The phenomenon of yellowing and mildew will appear when placed for a longer time
If this phenomenon occurs in an environment with high air humidity, this is because some manufacturers use glue with high alkalinity and store it in a humid place. Therefore, in order to ensure the quality of the product, good Glue and store in a place for ventilation.
Delamination of packaged products is mainly due to insufficient strength of the adhesive. It is recommended to choose a high-quality paper bag manufacturer, which can not only ensure the strength and stiffness, but also improve the quality and grade of cosmetic paper bag production.
