Technical Data:

Product description:

Aluminium foil of 30-50 µm with colourless primer or white nitro lacquer on one side and heatsealing lacquer on the other side.

Coating properties:

Colorless Primer and Coloured Lacquer:

  • Nitrocellulose or Polyester nature.
  • Excellent adhesion to aluminium foil (resistant to adhesive tape test).
  • Good printing results using nitrocellulosic inks and UV inks. (Inks' resistance is responsibility of the printer)
  • Resistant to heatsealing temperature (max. 220ºC 1s).
  • Water resistant (30 min at room temperature).

Heatsealing lacquers:

  • Authorized for contact with foodstuffs (FDA).
  • Water resistant (30 min at room temperature).
  • Resistant to boiling water (5 min/100ºC).
  • Lacquer porosity (15 min) < 5 pores/m2 (20g CuSO4 / 50cc HCl(35%) /1000cc. H2O) (The resistance to this test is up to 2 hours with the anticorrosive version of the lacquer)

There are different types depending of material to which the lid must seal:

  • Heatsealing lacquer to PS/PVC:
  • Peel strength to PS > 5.5 N/15mm. (180ºC, 40 kg, 1s)
  • Peel strength to PVC > 9 N/15mm. (180ºC, 40 kg, 1s)
  • Heatsealing lacquer to PVC:
  • Peel strength to PVC > 9 N/15mm. (180ºC, 40 kg, 1s)
  • Heatsealing lacquer to PP:
  • Peel strength to PP > 9 N/15mm. (200ºC, 40 kg, 1s)
  • Universal heatsealing lacquer to PP/PS/PVC/PET
  • Peel strength to PP > 9 N/15mm. (200ºC, 40 kg, 1s)
  • Peel strength to PVC > 9 N/15mm. (180ºC, 40 kg, 1s)
  • Peel strength to PS> 9 N/15mm. (180ºC, 40 kg, 1s)
  • Peel strength to PET > 9 N/15mm. (200ºC, 40 kg, 1s)
