Do you know the application of pressure sensitive adhesive, with the improvement of living standards, people's quality of life has also been improved. Wet wipes, as a common daily product, are mainly used to clean the skin. It is used when it is inconvenient to wash with water when going out. However, in order to make it convenient for consumers to use and provide good sealing, the manufacturer will stick a pp plastic sealing lid on the paper extraction port. The adhesive that binds the packaging bag to the plastic lid is hot melt pressure sensitive adhesive.

But there are too many types of hot-melt adhesives on the market. Choosing a bad hot-melt adhesive will not only affect the appearance, but also may cause wire drawing during the production process, and if the viscosity is not enough, the cover will fall off. therefore. The hot melt adhesive for wet wipes must meet the high and low temperature without falling off the cover, and it cannot affect the original appearance of the product after gluing. So, how to choose a high-quality hot melt adhesive suitable for wet wipe box lids? What should be paid attention to in the application technology of hot melt adhesive, and how can we make the cover of wet wipes and the outer packaging tightly stick together?

In order to develop a hot melt pressure sensitive adhesive suitable for wet wipe covers and packaging, first of all, let's understand the relationship between them:

Material characteristics of the lid: The main material of the wet wipe box lid is made of PP material, but it is difficult for ordinary hot melt adhesives to be compatible with PP materials, because the molecular structure of the pp material itself is much finer than that of other materials. Moreover, the surface of the PP material is too smooth, resulting in poor adhesion of the hot melt adhesive, and the low surface peel strength of the PP material makes the conventional hot melt adhesive difficult to bond.

It is precisely because of the bonding problem of PP material that it has been plaguing the entire adhesive industry, and it is a problem that needs to be overcome urgently in the hot melt adhesive industry.

Qixing New Material Co., Ltd. has developed a new type of hot-melt pressure-sensitive adhesive product, which is conducive to environmental protection and safe production, and has high production efficiency. White and transparent block, low odor and environmental protection, good initial adhesion, strong peeling force, strong holding force, strong pressure-sensitive performance, good for PP plastic boxes, PP plastic bags, PET plastic bags and other substrates The adhesive effect is good when applied to the wet wipe box cover, and even in the summer of high temperature, you will not worry about the cover falling off.

Application of hot melt pressure sensitive adhesive: It has very good gluing effect and is suitable for the equipment requirements of spray suction and roller gluing.

The hot-melt pressure-sensitive adhesive for the wet wipe box lid pays great attention to the smoothness of construction. As a small auxiliary material, the 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 the hot-melt pressure-sensitive adhesive and the operating temperature requirements of the product: because the viscosity directly affects the quality of the hot-melt adhesive. Therefore, temperature control is very important, so it is more suitable to use the temperature between 160~170℃.

2. Pay attention to equipment configuration: The set value of temperature at each point should be adjusted according to the on-site configuration of hot melt pumping cylinder, glue pump, glue conveying pipe and glue spraying machine.

3. Troubleshooting the failure of no glue from the nozzle: the glue tank, hose, nozzle, the temperature is not enough or there are impurities blocking the nozzle of the glue, the glue tank, tube, and gun head should be thoroughly cleaned with cleaning agent every three months , to ensure that the functions of the device can be used normally.
