Overview - Intercol Hotmelt Adhesives for Packaging

1. Base Technologies

  • Polyolefin Hotmelts
    • Exceptional thermal stability → less charring, longer machine uptime
    • Clean-running and low-maintenance
    • Adheres to difficult or coated substrates
    • Suitable for high-speed, powder-tight packaging
    • Broad temperature resistance: -40 °C to +70 °C
    • Food-safe options available (BRC, SML compliant, low odour)
  • EVA (Ethylene Vinyl Acetate) Hotmelts
    • Economical choice for general packaging
    • Quick setting speed for fast bonding cycles
    • Good adhesion to a variety of cardboard and paper substrates

2. Key Performance Features

FeatureBenefit in Packaging Lines
Outstanding thermal stabilityPrevents nozzle blockages and reduces downtime
High bond strengthSecures even hard-to-bond or coated cartons
Fast set speedEnables high-speed folding/cartoning
Low application temperature optionsReduces energy use and thermal stress on materials
Deep freeze resistanceReliable for frozen goods packaging
Food contact complianceSafe for primary food packaging

3. Common Packaging Applications

  • Folding cartons (side- and top-loading)
  • Wraparound cartons
  • Trays and case sealing
  • Multi-pack bundling
  • Powder-tight sealing (detergent, cereals, seeds, pet food)
  • Fresh produce and temperature-sensitive goods

4. Operational Benefits

  • Reduced microstops and maintenance
  • Versatility across multiple packaging formats
  • Compatibility with standard hot melt systems (e.g., Nordson)
  • Cost efficiency from higher mileage and lower adhesive consumption

✅ How to Choose

  • High-speed lines → PO or Futura series for mileage & clean running
  • Challenging substrates (varnished, PE-coated) → Polyolefin grades
  • Frozen goods → Deep Freeze HM
  • Powder products → Sift-Proof HM
  • Cost-sensitive, standard board → EVA HM
