ABSTRACT:
Oxygen barrier films having a greatly improved dynamic coefficient of friction, and specifically, oxygen barrier films having an exceptionally low dynamic coefficient of friction, reduced moisture sensitivity and good oxygen barrier properties over a wide range of relative humidities. The low coefficient of friction is obtained by using film layers which are blends of a polyamide component and a high density polyethylene which surround an oxygen barrier layer, such as an ethylene vinyl alcohol layer.
