Cast coated paper, woodfree , pure ECF pulp ,calendered off machine, high vacuum gold metallised and an ULTRA WS treatment.
The ultra WS treatment of the face material avoids the creases formation and reduces the water absortion on the face surface. The test of resistance to immersion in water-ice is carried out by sticking a blank(unprinted) label on a standard glass bottle. Five days after the label is stuck on, it is submerged in an ice bucket containing icy water for a minimum period of 4 hours and its resistance to immersion is checked.
