Copolyamide Hot Melt Granule Low Melt Point PA Adhesive Pellets for Honeycomb Blinds Production

Copolyamide Hot Melt Granule for Honeycomb Blinds Production

Our copolyamide (CoPA) hot melt adhesive granules are specially formulated for the high-speed production of honeycomb blinds. This low melting point thermoplastic adhesive melts and flows evenly at moderate temperatures, creating a strong yet flexible bond between fabric layers, fabric to paper honeycomb cores, and fabric to aluminum profiles. The 100% solvent-free formula ensures a clean working environment, consistent lamination quality and stable output in continuous production lines.

Key Advantages

• Low melting point (85-105°C): Saves energy, protects heat-sensitive blind fabrics and shortens heating cycles.
• High bonding strength: Reliable adhesion to polyester, cotton, non-woven, paper and aluminum substrates commonly used in honeycomb blinds.
• Excellent flexibility: Cured adhesive lines stay soft and foldable, perfectly matching collapsible honeycomb structures.
• Washable & dry-cleanable: Resists water and detergent, keeping pleats firmly bonded after cleaning.
• Thermal stability: No yellowing or viscosity drift during repeated heating and production pauses.
• Solvent-free & eco-friendly: REACH and RoHS compliant, safe for indoor residential use.
• Uniform granule size (3-5 mm): Stable feeding, fast melting and homogeneous glue lines in extruders and melt tanks.

Technical Parameters

Application in Honeycomb Blinds Production

Dosage and temperature can be adjusted according to line speed and fabric type. For best results, pre-dry paper substrates and keep fabric moisture below 5%. The granules are compatible with standard hot melt application equipment including screw extruders, slot-die coaters and glue tanks. After bonding, allow 30-60 seconds of open time before pressing, and cool under pressure for 5-10 seconds to achieve maximum peel strength.

FAQ

Q1: What application temperature should I use?
A: We recommend 130-180°C depending on your line speed and fabric heat resistance. Start at 150°C and adjust in 5°C steps until a full wet-out glue line is achieved.

Q2: Can this granule bond non-woven fabric to paper honeycomb cores?
A: Yes. It provides excellent adhesion to polyester/cotton fabrics, non-woven materials, paper cores and aluminum profiles used in honeycomb blind structures.

Q3: Is the adhesive washable?
A: Yes. The cured adhesive offers good water and detergent resistance, and bonded pleats remain intact after washing and dry cleaning.

Q4: What is the MOQ and packaging?
A: MOQ is 1000 kg. Standard packaging is 20 kg kraft paper bags with PE inner liner, palletized with stretch film for safe sea or air shipment.

Q5: Can you provide samples for testing?
A: Yes, free samples are available. Please contact us with your fabric type, line speed and application method so we can recommend the most suitable grade.
