Abstract
Bonded polymeric film laminates comprising core polymer film layers individually coated on at least one side with a heat fusible polymer layer and fusion bonded together by the application of heat and pressure at a temperature at which each heat fusible polymer coating bonds together adjacent core polymer film layers, where the melting point or softening temperature of the heat fusible polymer is at least 3° C. below that of the core layer polymer, and the lamination temperature is at or above the melting point or softening temperature of the heat fusible coating polymer, where the heat fusible polymer coating layers are thinner than the core polymer film layers, where the coated core polymer film layers are uniaxially stretched by 2× to 40×, and the stretched coated core polymer film layers are cross-plied. Methods for forming the laminates, coated films from which the laminates are formed, and articles formed from the laminates are also disclosed.
