A flexible laminate structure that is formed from a first substrate, a second substrate, and discrete regions of a functional material sandwiched therebetween is provided. In particular, the first and second substrates contain thermoplastic polymers that are fused together at certain portions such that fused portions and unfused portions are formed. The unfused portions form pockets that contain the functional material and are relatively small in size. In some embodiments, for example, the pockets have an approximate width to height ratio of less than about 10. Se proporciona una estructura laminada flexible que es formada de un primer substrato, de un segundo substrato y de regiones discretas de un material funcional colocado en forma de emparedado entre los mismos. En particular, los substratos primero y segundo contienen polimeros termoplasticos que son usados juntos en ciertas partes de manera que las partes fusionadas y las partes no fusionadas son formadas. Las partes no fusionadas forman bolsas que contienen un material funcional y son relativamente pequenas en tamano. En algunas incorporaciones, por ejemplo, las bolsas tienen una relacion de ancho a altura aproximada de menos de alrededor de 10.
