Product description

Paperboard with aluminium foil laminated onto the reverse side is suitable for packaging applications where sensitive products must be protected from light, moisture and gases. The aluminium lamination makes the board practically impermeable to light, moisture, flavours and gases.

An LDPE coating on top of the aluminium foil protects the foil from aggressive products, and makes the surface sealable. The printing side of the baseboard can be coated with LDPE, as with standard two-sides plastic coated board.

Additional properties

The aluminium foil lamination gives:

  • Good sealability
  • Excellent moisture, flavour and gas barrier from the inside
  • Excellent light barrier

The reverse side is normally an NSO (non-set-off) surface for reduced ink set-off tendency and improved friction.

  For Alubarrier the estimated increase in stiffness as a result of the lamination process is, for machine direction 15-50%, for cross direction 40-65%, in relation to the specified baseboard value. The lower the baseboard grammage, the higher the percentage increase.
