Field of Application
Flat lamination is one of the oldest applications in the wood and furniture industry. Typically, it involves coating wooden substrates with various decorative materials. Laminating materials come in a wide variety, including resin decorative papers and veneers, as well as thermoplastic foils or laminates such as HPL and CPL. Wood panels laminated with decorative surface materials represent state-of-the-art technology. They find extensive use in furniture, doors, windows, and flooring industries, as well as in the construction of exhibition stands and retail fixtures.
The extremely diverse material combinations and exceptionally high quality expectations demand highly efficient adhesives.
In addition to PVAc dispersion adhesives and UF adhesives, moisture-curing PUR hot melt adhesives are increasingly becoming the preferred choice due to their excellent heat and moisture resistance. Jiwei offers a comprehensive portfolio of flat laminating adhesives to optimally meet customer requirements.
Flat lamination is widely used in the following industries:
Flat bonding of large panels – Plastic panels, wooden boards, inorganic panels, melamine (triamine) boards.
Molded door panel bonding – Used for assembling and securing door components.
WPC plastic flooring bonding – Ensures durability and adhesion in flooring applications.
Aluminum sheet bonding – Suitable for rolling or scraping application methods.
High-gloss surface bonding – Compatible with PETG, acrylic, and other decorative materials.
Plastic wall panel cladding – Used in interior and decorative applications.

Application Method for PUR Flat Laminating Hot Melt Adhesive
Identify the substrates to be bonded (e.g., MDF, melamine board, plywood, solid wood, chipboard, wood-plastic composite, aluminum sheet, glass-fiber reinforced magnesium board) and materials (e.g., PVC film, PET film, PP film, acrylic, leather, paper). Consult the PUR flat laminating hot melt adhesive supplier for suitable adhesive recommendations.
Set the machine's adhesive melting temperature, roller pressure, and adhesive application volume.
Feed the panels through the conveyor belt into the dust removal system to eliminate surface dust.
Apply the PUR flat laminating hot melt adhesive evenly onto the panel surface, then press the laminating material flat onto the panel.
It is recommended to let the bonded panels rest for at least 24 hours before proceeding to subsequent processing steps.
PVC film requires back coating. MDF surfaces must be flat and clean. PVC-coated steel, wood-plastic composite, and acrylic sheets require surface activation treatment.
Recommended ambient temperature: 15-30°C. Heating equipment is required below 10°C.
PUR flat laminating hot melt adhesive must not come into contact with air or water vapor prior to use.
Seal the adhesive nozzle during production stoppages. If downtime exceeds one week, clean the adhesive hose and nozzle.
