How to distinguish the quality of paper and plastic?

How to distinguish the quality of paper and plastic? The quality of products made from paper and plastic with a lot of peculiar smell is very poor. Adhesives for paper tubes are commonly known as paper tube glue, paper tube glue, etc. It is a special adhesive for making various paper tubes, paper barrels, paper cans and related paper products.

Paper, cloth, plastic film, metal foil and other thin and soft materials are usually wound into bundles of paper tubes (paper tubes) to make finished paper core rolls. These paper tubes are generally made of kraft paper or other raw material paper by mechanically rolling and bonding. The adhesive used is called paper tube glue.

There is a new type of special glue for paper tube on the market, which is a new type of high-performance product made of high molecular polymer, and its appearance is milky white viscous liquid. It has good initial adhesion, short initial adhesion time, high bonding strength, good fluidity and storage stability, and excellent properties such as bonding without warpage. The paper tube made of paper plastic has high strength, good stiffness, and no brittleness. The glue can be used in the production and use of various high, medium and low paper tube machinery, and can also be used for the production of paper drums; it replaces white latex and poly Adhesive for paper tube bonding such as vinyl alcohol.

The paper tube formed with the paper tube glue is obviously higher in hardness and strength than the paper tube bonded with other glues such as white latex and polyethylene glue. At the same time, the adhesive film has good moisture resistance, which can fully meet the moisture resistance requirements of various paper tubes. Using the glue can not only significantly increase the hardness and strength of the paper tube, but also greatly reduce the cost. It is a new type of low-cost, high-performance paper tube glue that replaces the traditional paper tube glue.
