Hot melt adhesive particles are a new type of environmentally friendly material, featuring fast curing speed, simple process, and no risk of flammability or explosion. Hot melt adhesive particles do not contain organic solvents. During the production, manufacturing and application process, there is no discharge of three wastes, and it does not cause environmental pollution. It belongs to green and environmentally friendly products and is the mainstream product in the development trend of adhesives.

Hot melt adhesive bonding is a process that fully utilizes a hot melt adhesive machine to melt the hot melt adhesive through heating. After the adhesive is melted, it turns into a liquid. Through the hot melt adhesive tank or hot melt adhesive gun of the hot melt adhesive machine, it adheres to the surface of the bonding object. Once the hot melt adhesive cools down, the bonding is completed. Hot melt adhesive particles are reversible thermoplastic materials, featuring excellent elasticity, softness and low-temperature bending resistance. They have a strong bonding effect on various different materials.
Hot melt adhesive particles, being solvent-free and 100% solid, pose no risk of flammability or explosion during use, processing or transportation. In addition, it has the following advantages:
In fact, up to now, the variety of hot melt adhesive particles has been increasing, and their applications have become more and more extensive. They can be used to bond leather, books, pearl cotton, wood, plastic bags, clothing, textiles, etc. However, they are mainly applied in books, pearl cotton, hand-held bags, packaging (corrugated paper and thick cartons), and the wireless binding of books.
1. Book and periodical binding industry:
Wireless adhesive binding for books and periodicals has become the main method of book and periodical binding in China due to its fast processing speed, high production efficiency, short cycle, stable quality, low labor intensity and good binding quality. At present, most of the hot melt adhesives used for wireless binding of books and periodicals in our country are EVA hot melt adhesives.
2. Pearl cotton packaging industry:
Pearl cotton, also known as EPE, is a foamed polyethylene polymer. Pearl cotton has many advantages such as water-proofing, moisture-proofing, shock absorption, sound insulation, good plasticity, strong toughness, recyclability, environmental friendliness, and strong impact resistance. It also has excellent chemical resistance. Pearl cotton packaging is widely used in daily life and is frequently employed in the packaging of fragile items such as electronic appliances, instruments and meters, medical devices, hardware and lighting fixtures, handicrafts, glass and ceramics, toys, fruits and vegetables, and alcoholic beverages.
3. Application of Velcro products:
When it comes to products like Velcro, many people definitely use it every day. Whether it’s the small switch on the cuff of a down jacket or the binding rope on the computer wire that many people use, they are all concrete forms of Velcro products. The material composition of this product is very diverse. It can be made of nylon or polyester fabric. In the use of Velcro, adhesives are often needed to fix it to certain materials, such as cuffs, bag openings and other positions. And in the production process, hot melt adhesives are indispensable.
4. Packaging manufacturing industry:
For the packaging and sealing of food, beverages, instant noodles, cigarettes, beer, medicine, etc., most applications are made by using hot melt adhesives and sealing machines. Packaging hot melt adhesive has obvious advantages in the packaging manufacturing industry: it is elegant and does not harm the packaging printing plan. Convenient transportation maintenance and storage management; It is conducive to automated machinery and improving high efficiency. Low-carbon and environmental protection, energy conservation, and ecological environment protection.
5. Automotive manufacturing industry:
Hot melt adhesive particles are a type of adhesive that is extremely environmentally friendly and suitable for high-speed automatic assembly line operations nowadays. The automotive industry is developing rapidly nowadays, especially in China, which has now become the world’s largest producer and seller of automobiles. With the improvement of the automation level in automotive production, the automotive industry requires a large number of adhesives that can bond quickly, adapt to high-speed automated production, and are environmentally friendly. Hot melt adhesives precisely meet all these requirements. Therefore, hot melt adhesives are increasingly widely used in the automotive industry, and their usage has been rising year by year. They have become an irreplaceable type of adhesive in the automotive industry.
6. Hot melt adhesive for furniture edge banding:
China is a country lacking in wood. Apart from a few high-end furniture pieces that use solid wood, most furniture is made of fiberboard, particleboard or sawdust board. The edges of the furniture boards must be bonded with hot melt adhesive to enhance the aesthetic appeal, resembling solid wood furniture.
Hot melt adhesive particles for high-speed sealing of cardboard boxes are not necessarily better with higher tensile strength. The sealing fastness also depends on the wetting of the corrugated paper by the adhesive particles, the cooling speed of the adhesive dots, the spraying rhythm, and the pulling direction during transportation. Sunlife hot melt adhesive recommends […]
Direct answer: For paper bag rope adhesion, hot melt adhesive particles with high initial adhesion, good flexibility, and a softening point of 75-85 ℃ should be used. The diameter of the adhesive point should be 8-12mm, with one point at each rope hole. Press and hold for 3-5 seconds.The key is not in the amount […]
By focusing on six things, book and magazine printing factories can control costs and ensure stable supply through centralized procurement of hot melt adhesive granules: clarifying annual usage, locking technical parameters, supplying in batches at locked prices, setting safety stock, establishing acceptance standards, and building alternative suppliers. The following list can be directly used as […]
Environmental RoHS certification requirements for hot melt adhesive granules: Compliance list for dry goods Hot melt adhesive particles exported or imported into the brand supply chain often need to comply with environmental directives such as RoHS. RoHS restricts harmful substances such as lead, cadmium, mercury, etc. Below is a compliance checklist for procurement and quality […]
