ABSTRACT:
A laminator film having a plurality of continuous, fine grooves on its surface in the lengthwise direction of the film. When the laminator film and a target film to be laminated are passed between a pair of hot, engaged rollers, the air between the grooved surface and the target film can be guided out through the grooves while the grooves are flattened by the pressure and heat of the rollers. Thus, it is completely preventive of air accumulation by virtue of their continuous fine grooves, giving a great improvement in adhesiveness, surface smoothness and transparency to the resulting laminated product.
