A multilayer coextruded film which comprises
- (a) a core layer of an elastomeric material;
- and
- (b) at least one skin layer of a thermoplastic material, said skin layer being secured to said core layer at spaced apart contact areas and having a microundulating surface in the machine direction or transverse direction such that the film has a gloss of less than 20 as determined by ASTM D1003-67.
A multilayer coextruded film comprising
- (a) an elastomeric core layer;
- and
- (b) two thermoplastic skin layers secured to opposite sides of the core layer, said skin layers being secured to the core layer at random spaced apart contact areas to provide each skin layer with microundulating configuration in the machine direction or transverse direction, said film having a gloss value less than 20 as determined by ASTM D 1003-67.
