Abstract
Foamed films of blends of low density polythene and a crystalline polyolefine which have been subjected to surface treatment.
Claims8
A wall or ceil covering comprising a printed open celled foamed film of foamed polyolefine derived from a blend containing between 60% and 90% by weight of low density polythene and between 40% and 10% by weight of a crystalline polyolefine, said foamed film having a bulk density between 0.1 and 0.4 grams/cc and an open cell structure in the range of 40 to 90% open cells, the surface of said film having been subjected to surface treatment on at least one surface to improve the ink bonding properties of that surface, said film being characterized by higher abrasion resistance and higher dry ink abrasion resistance than corresponding surface treated
