ABSTRACT:
The present invention relates to laminates of polyolefin laminae and strips chemically bonded in the solid state by reactions initiated by cross-linking catalysts interspersed at the interface of contacting laminae. Catalysts to initiate crosslinking reactions at temperatures below the melting point of the respective laminae are employed. A preferred application of the laminate is a chemically bonded structure of highly oriented, preferably uniaxially oriented film with the direction of orientation of uniaxial orientation at an angle to each other in successive laminae.
