Hot melt glue coating machines use the fast bonding characteristics of hot melt adhesive to achieve efficient and environmentally friendly material compounding and fixing in multiple industrial fields. It has a wide range of applications. The following is a classification of key industries and typical case descriptions:

1. Packaging industry

Carton and carton sealing

Application scenarios: automated edge sealing of food, medicine, and daily chemical packaging boxes.

Advantages: Hot melt adhesive cures quickly (1-3 seconds), has no solvent residue, and meets environmental protection standards; the coating is uniform to avoid glue leakage and insufficient box strength.

Labels and composite packaging

Application scenarios: bonding of self-adhesive labels and aseptic packaging films (such as milk cartons).

Advantages: Resistant to low temperatures (-20℃) and high temperatures (80℃), suitable for cold chain transportation and high-temperature sterilization processes.

2. Sanitary products industry

Disposable sanitary products

Application scenarios: elastic waistbands, three-dimensional guardrails, and diversion layer coating of diapers and sanitary napkins.

Advantages: Hot melt adhesive has good softness and does not irritate the skin; the coating accuracy is high (±0.1mm) to avoid glue penetration and contamination.

Medical protective materials

Application scenarios: bonding of surgical gowns and mask ear straps.

Advantages: Hot melt adhesive meets medical-grade hygiene standards, has no odor after curing, and is washable.

3. Automobile and electronics industry

Automotive interior parts

Application scenarios: bonding of ceilings, carpets, and sound insulation cotton.

Advantages: Hot melt adhesive is resistant to high temperatures (above 120°C), has good shock resistance, and is suitable for complex automotive working conditions.

Fixed electronic components

Application scenarios: bonding and packaging of PCB boards, battery packs, and flexible circuit boards.

Advantages: Hot melt adhesive has good insulation and low volume shrinkage after curing, which avoids component displacement.

4. Construction and building materials industry

Waterproof roll composite

Application scenarios: composite of asphalt waterproof roll and polymer film.

Advantages: Hot melt adhesive has strong weather resistance, adapts to -30°C to 80°C environment, and extends the service life of the roll.

Decorative material bonding

Application scenarios: bonding of PVC floors and wall panels.

Advantages: After the hot melt adhesive is cured, there are no bubbles, the flatness is high, and it is suitable for large-scale construction.

5. Textile and shoe material industry

Non-woven fabric composite

Application scenarios: The inner layer of masks, surgical gowns, and filter materials.

Advantages: Hot melt adhesive has good air permeability and does not affect the filtering performance of non-woven fabrics.

Shoe material bonding

Application scenarios: Bonding of soles and uppers.

Advantages: Hot melt adhesive has good elasticity after curing, which is suitable for repeated bending of sports shoes.

6. Other emerging fields

New energy industry

Application scenarios: Bonding of lithium battery tabs and photovoltaic backplanes.

Advantages: Hot melt adhesive has good conductivity (for tabs) or strong insulation (for backplanes), which is suitable for high-precision requirements.

Smart home

Application scenarios: Bonding of watch straps of smart wearable devices (such as watches).

Advantages: Hot melt adhesive has good flexibility after curing, which is suitable for human movement.

The application fields of hot melt glue coating machines cover packaging, sanitary products, automotive electronics, construction materials, textile and footwear materials, and emerging industries. Its core advantages lie in environmental protection, high efficiency, and process flexibility. Different industries have different performance requirements for hot melt adhesives (such as temperature resistance, softness, and bonding strength). Therefore, the selection needs to be combined with the specific substrate characteristics and production requirements. In the future, with the development of green materials and intelligent technologies, hot melt glue coating machines will play a key role in more high value-added fields.
