Patent ID: 7976925

Claim:
A cross-laminate comprising: a first coextruded film A having a film A main direction of uniaxial or unbalanced biaxial molecular orientation and including: a continuous main layer comprising a first polymer material selected to have a high tensile strength, a continuous bonding layer comprising a second polymer material and disposed on a first surface of the main layer, and an array of substantially parallel film A first strands coextruded on a top surface of the bonding layer in a spaced apart configuration, and comprising a third polymer material different from the first and second polymer materials, where a separation between adjacent strands of film A array is between 2 mm and 8 cm measured from a middle of one strand to a middle of an adjacent strand, a second coextruded film B having a film B main direction of uniaxial or unbalanced biaxial molecular orientation and including: a continuous main layer comprising a fourth polymer material selected to have a high tensile strength, a continuous bonding layer comprising a fifth polymer material and disposed on a first surface of the main layer, and an array of substantially parallel film B first strands coextruded on a top surface of the bonding layer in a spaced apart configuration, and comprising a sixth polymer material different from the fourth and fifth polymer materials, where a separation between adjacent strands of film B array is between 2 mm and 8 cm measured from a middle of one strand to a middle of an adjacent strand, where the film A and the film B are arranged such that the first surface of the film A faces the first surface of the film B and their bonding layers and arrays of strands on the first surfaces face each other and such that the film B main direction crosses the film A main direction and the array of the film B first strands cross the array of the film A first strands, a first bonding pattern formed between the first surface of the film A and the first surface of the film B comprising: first bonds comprising spot-bonds formed directly between the film A first strands and the film B first strands, where the film A first strands intersect the film B first strands, second bonds comprising contact lines between the film A bonding layer and the film B first strands or the film B bonding layer and the film A first strands, and third bonds comprising contact regions between the film A bonding layer and the film B bonding layer, where the regions are devoid of the film A first strands and the film B first strands, where the first bonds have a higher bond strength than a bond strength of the third bonds, and where the strands have a thickness of no more than 30% of a thickness of their respective films at their thickest.
