Where is hot melt adhesive used?

Here are the main application scenarios for hot melt adhesives:

1. Packaging Industry
* Carton Sealing: Hot melt adhesive is the mainstream adhesive for carton sealing, especially suitable for automated production lines. Its rapid curing characteristics (usually curing within seconds) significantly improve packaging efficiency while ensuring a strong bond and preventing opening during transportation.

* Carton Forming: Used for folding and bonding cartons for food, pharmaceuticals, cosmetics, etc., such as medicine boxes, toothpaste boxes, chocolate boxes, etc. The flexibility of hot melt adhesive can adapt to multiple openings and closings of cartons.

* Labeling: In labeling bottled and canned products (such as beverages and cosmetics), hot melt adhesive provides water- and oil-resistant adhesion, ensuring that labels do not fall off in humid or low-temperature environments.

* Cushioning Material Fixing: Used to fix cushioning materials such as foam and bubble wrap inside cartons to prevent items from shifting during transportation.

2. Wood Processing and Furniture Manufacturing

Board Joining: In the joining of engineered wood products (such as particleboard and medium-density fiberboard), hot melt adhesives can replace traditional glues, achieving rapid bonding without formaldehyde release, meeting environmental protection requirements.

Furniture Edge Banding: Used for bonding edge banding strips on furniture edges, such as PVC or wood grain edge banding strips for cabinets and wardrobes. The heat and water resistance of hot melt adhesives ensures that the edge banding strips will not peel off for a long time.

Woodworking Assembly: In the assembly of furniture such as chairs and tables, hot melt adhesives can quickly fix tenons and connectors, improving production efficiency.

3. Footwear and Apparel Industry

Footwear Bonding: Used for bonding soles and uppers of shoes, such as in the manufacture of athletic shoes and leather shoes. The flexibility of hot melt adhesives can adapt to the bending and deformation of shoes while providing high-strength bonding.

Apparel Seaming: Hot melt adhesive is used for sealing seams in outdoor clothing (such as waterproof jackets and ski suits) to achieve waterproof and windproof effects, replacing traditional sewing thread.

4. Bra Strap Fixing: Used for bonding bra straps to the garment body, ensuring comfort and preventing slippage.

5. Electronics and Electrical Industry

Component Fixing: In fixing electronic components such as circuit boards and sensors, hot melt adhesive provides insulating and moisture-proof bonding effects, while also being suitable for automated production.

Cable Bundling: Used for bundling and fixing wires and cables, preventing loosening or wear.

Mobile Phone Accessory Bonding: In the assembly of mobile phone screens, back covers, and other components, hot melt adhesive enables precision bonding while meeting the requirements of thin and lightweight designs.

6. Automotive Interior and Components

Interior Bonding: Used for bonding interior materials such as car seats, carpets, and headliners. The high temperature resistance and aging resistance of hot melt adhesive ensure long-term durability and prevent detachment.

Component Fixing: In fixing automotive wiring harnesses, sensors, and other components, hot melt adhesive provides shock-resistant and anti-loosening bonding effects.

Electronic Component Fixing 6. Medical and Hygiene Products

Disposable Products: Used for edge bonding of disposable hygiene products such as diapers and sanitary napkins. The non-toxicity and flexibility of hot melt adhesives ensure skin comfort.

Medical Equipment: In the assembly of some medical devices, hot melt adhesives provide sterile and chemically resistant bonding.

7. Construction and Decoration

Sound Insulation Material Fixing: Used to fix materials such as sound-absorbing cotton and sound insulation felt to reduce noise transmission.

Flooring Installation: In the splicing of some flooring, hot melt adhesives provide fast and strong bonding.

Advantages of Hot Melt Adhesives
