Abstract:
1. A crosslaminate comprising at least two bonded-together films (A) and (B), each comprising an orientable, crystalline thermoplastic polymer material and each being uniaxially oriented or being biaxially oriented with one direction dominating, the directions in (A) and (B) crossing each other, the bonding being an intermittent bonding which leaves more than 50% of the film area unbonded and which forms pockets to encapsulate gas, whereby the gas within each pocket has a volume which referring to the relaxed state of the laminate and 1 atmosphere ambient pressure is at least double the volume of the polymer material, where a) the gauge of each of the films (A) and (B) is at the highest 30 g m b) the bonding consists in a combination of a pattern of rectilinear or curved bonding lines ( c) the longest extension of each pocket in any direction is at the highest 50 mm.
