In packaging materials, packaging binders have always occupied a very important part. Hot melt adhesive is a new type of binder developed to meet the requirements of today's packaging industry for harmless, energy-saving, resource-saving and no environmental pollution. Hot melt adhesives are characterized by 100% solids and do not contain water or other solvents, so there is no environmental pollution and residual solvent toxicity. In addition, it has a high degree of adhesion, and different compositions of hot melt adhesives can be selected according to different occasions.
Hot melt adhesive products have been applied to all aspects of people's lives, covering people's eating, wearing, living, using, traveling, playing in various fields, eating bowls of instant noodles, drinking bottles of water, drinking a glass of wine, wearing clothes, shoes, hats, buildings, houses, cars, trains, planes, refrigerators, color TVs, washing machines, toilet paper, toothpaste, soap, handicrafts to beautify living space, decorative paintings, craft flowers, children's toys, gifts, etc., all have the application of hot melt adhesive. It can be said that in modern people's lives, the application of hot melt adhesive is everywhere.
The bonding of hot melt adhesive is the melting of the hot melt adhesive through a hot melt adhesive machine. The melted glue becomes a liquid and is then sent to the surface of the object to be glued through the hot melt glue gun and the hot melt adhesive tube of the hot melt adhesive machine. After the hot melt adhesive has cooled, the bonding is complete. In order to give full play to the advantages of hot melt adhesive in bonding, it is necessary to match the corresponding quality and reliable hot melt adhesive with high-quality hot melt adhesive.
Hot melt adhesive bonding is the use of hot melt machine through heat melt adhesive, melt glue into a liquid, through the hot melt machine throat and spray gun, sent to the surface of the bonded object, packaging hot melt adhesive after cooling to complete the bonding, it can meet the requirements of carton sealing, and overcome the defects in the previous carton sealing form.
