Deep Freeze Carton Sealing

Technomelt Supra 100 Cool

Initial Situation

Application: Deep freeze pizza in a printed carton
Adhesives: Old technology EVA based hot melt
Adhesive Application Equipment: Tank-based systems with and without automatic feeding

Goals Defined:

  • Optimal processing properties showing clean and precise application without stringing
  • Lower adhesive consumption
  • High adhesion properties and suitable for deep freeze
  • Energy savings for application equipment and also the air conditioning in production area
  • Increase operator safety by reducing risk of severe burns (application temperature from 180°C to 100°C)

Application Details:

  • Deep freeze pizza in printed carton
  • Application – Carton sealing
  • Volume – 50 tons of adhesive per year
  • Equipment – Nordson ProBlue
  • Production – 100,000 boxes per week
  • EVA based hot melt
  • High adhesion profile
  • Application temperature 180°C

 

New Solution:

  • Technomelt Supra 100 Cool
  • High adhesion profile
  • Application temperature 100°C

 

    Results:

    • Energy consumption (including air conditioning) was 1.2 kW/h when running at 180°C, now 0.7 kW/h achieving 42% energy reduction.
    • A glue volume reduction of 21% from 50 tonnes per year to 39.5 tonnes
    • Spare parts, the life expectancy for machine parts was doubled meaning a 50% reduction on spares purchased
    • Processing properties, no stringing at all and zero adhesive related line stoppages since introduction
    • No adhesive related health and safety incidences since introduction
    • Machine start up time reduced from 50 minutes down to 20 minutes

    “The introduction of Technomelt Supra 100 Cool was a revelation for our production. I didn’t realise that there were so many savings to be made by switching to a mPO adhesive, that combined with the temperature reduction will save us thousands of pounds in the future. We’re very happy we changed”.
