What are the advantages of environmentally friendly hot melt adhesives? In what industries is it commonly used?

Hot melt adhesive is a new type of environmentally friendly material, which has the advantages of fast curing speed, simple process, and no flammable or explosive danger. Hot melt adhesive does not contain organic solvents, no waste emissions in the process of manufacturing and application, does not cause environmental pollution, belongs to green environmental protection products, is the mainstream product of the development trend of adhesives.

Hot melt adhesive bonding is to make full use of the hot melt adhesive machine through the heat to melt the hot melt adhesive, the glue after melting into a class of liquid, through the hot melt adhesive machine hot melt hose and hot melt glue gun, sent to the surface of the bonded material, hot melt adhesive cooling is completed the bonding. Hot melt adhesive is a reversible thermoplastic material, with good elasticity, softness and low temperature bending resistance, and has a strong bonding effect on a variety of different materials.

Because hot melt adhesive contains no solvent and is 100% solid, there is no danger of flammability or explosion during processing and transportation. In addition, there are the following advantages:

(1) Fast curing speed, cooling is curing, high production speed, saving equipment space.

(2) The bonding process is simple, less waste, and there is no mixing problem.

(3) 100% solidified components, can be fully utilized, less waste, can reduce transportation and storage costs.

(4), can be followed by a wide range of substrates, can be automated processing.

(5), excellent chemical and physical properties, with high bonding strength and flexibility.

(6) Do not use organic solvents, no VOC pollution problems.

(7) Environmentally friendly materials, waste can be naturally degraded.

In fact, the development of now more and more varieties of hot melt adhesive, more and more widely used, can be bonded leather, glass, metal, wood, luggage plastic, medical, textiles, etc., but mainly used in labels, express bags, cars, packaging (corrugated paper and thick cartons), books wireless binding and woodworking welt.

1, packaging manufacturing industry

Food, beverages, instant noodles, cigarettes, beer, medicine and other packaging boxes, most of the application of hot melt adhesive sealing machine to achieve. The packaging thermal sol has obvious advantages in the packaging manufacturing industry: beautiful and generous, and does not harm the packaging printing plan; Convenient transportation, maintenance, storage management; Conducive to automation machinery, improve efficiency; Low carbon environmental protection, energy conservation, ecological environment protection.

2, Automobile manufacturing industry

Hot melt adhesive is a kind of adhesive which is extremely environmentally friendly and suitable for high-speed automatic assembly line operation. Nowadays, the automobile industry is developing rapidly, especially in China, which has become the world's largest automobile production and marketing country. With the improvement of the automatic level of automobile production, the automotive industry needs a large number of fast bonding, and can adapt to high-speed automatic production and environmental protection adhesives, hot melt adhesive just meet all the above requirements, so hot melt adhesive is used more and more widely in the automotive industry, the use of it has increased year by year, and has become an irreplaceable adhesive in the automotive industry.

3, textile applications

Hot melt adhesive is one of the most used adhesives in textile, especially clothing processing, and is widely used in bonding non-woven fabrics, carpet seams, clothing linings, zippers, etc.

4, hot melt pressure sensitive adhesive

It is mainly suitable for women's sanitary napkins, children's diapers, bed MATS, elderly incontinence supplies, etc. In particular, the latter is accompanied by the continuous aging of China's population structure. The market demand for elderly incontinence products is likely to increase rapidly in the future.

4. Label industry

Hot melt adhesive is mostly used in plastic bottle labels, such as Coca-Cola, Wahaha and other plastic bottles of outsourcing paper bonding, bonding material is polyethylene plastic bottles (PET, PE, PP, etc.) and PP, PE plastic film; Most of the construction process is a strip construction, be sure to meet the needs of good temperature resistance, smooth construction, specific users will also pay attention to the appearance of the color needs, usually colorless transparent is appropriate.

5. Express delivery industry

The earliest delivery bags used destructive double-sided tape. And we are proud that we have destroyed the double-sided tape market again accounting for more than 80% of the market share. With the rapid development of the market and the progress of equipment, the logistics industry has a colorful scene, and the express bag factory has its own glue production, improve efficiency and save costs. According to the needs of customers, for new materials, recycled materials and other special needs of customers, our company has developed a series of express bag destruction sealers.
