Wet Paper Cover Hot Melt Adhesive

Wipes, as a common daily product, are mainly used to clean the skin. When it is not easy to clean with water outside, it is used and discarded. However, in order to make it easy for consumers to access and provide good sealing, the manufacturer will stick a sealed box cover made of pp plastic on the paper opening. The adhesive that binds the packaging bag and the plastic lid together is a new type of hot melt pressure sensitive adhesive.

However, there are too many types of Binding Agent on the market, and the choice of a bad Hot Melt Adhesive not only affects the appearance, but also may occur in the production process, and if the viscosity is not enough, the cover will fall off. Therefore. The hot melt adhesive of wet wipes must meet the high and low temperature without falling off the cover, and the original appearance of the product can not be affected after gluing. So, how should we choose high-quality hot melt adhesive suitable for wet wipes box cover? What should we pay attention to in the application of hot melt adhesive technology? How can we make the wipes cover stick closely with the outer packaging?

The main material of the wipes box cover is made of PP material, but the general hot melt adhesive is difficult to be compatible with PP material:
Because the molecular structure of the pp material itself is much finer than that of other materials, and the surface of the PP material is too smooth, resulting in poor adhesion of the hot melt adhesive, and the low peeling strength of the surface of the PP material leads to the difficulty of conventional hot melt adhesive bonding.

Application of hot melt pressure sensitive adhesive:
-- Has a very good gluing effect, suitable for the Equipment requirements of spraying and roller gluing.

Hot melt pressure sensitive adhesive for wet wipes box cover pays great attention to the fluency of construction. As a small auxiliary material, hot melt pressure sensitive adhesive pursues a kind of stability. Therefore, in the production operation, we must pay attention to the following requirements:
1. Pay attention to the viscosity of hot melt pressure sensitive adhesive and the operating temperature requirements of the product: because the viscosity directly affects the quality of hot melt adhesive. Therefore, temperature control is very important, so the general use temperature between 160 and 170℃ is more suitable.
2. Pay attention to equipment configuration: Adjust the temperature setting values of each point according to the on-site configuration of hot melt cylinder, glue pump, hose and glue spraying machine.
3. Troubleshooting of nozzle failure: spray failure of glue cylinder, hose, nozzle, insufficient temperature or impurities blocking the nozzle, thoroughly clean the glue cylinder, tube, and gun head with cleaning agent every three months to ensure that the functions of the equipment can be used normally.
