Abstract
A method of forming a thermoplastic layer on a flexible, two-dimensional substrate is provided. In the steps of the method, a thermoplastic powder is provided having a melt flow index of at least 0.008 grams/10 minutes, the powder is applied to at least one surface of the substrate to form a particle layer, and the coated substrate is subjected to elevated heat and pressure until particle layer is fused into a continuous layer and the continuous layer is bonded to the substrate. The invention also includes a powder for preparing the thermoplastic layer and a method of making the powder.
