Abstract

As películas podem ser usadas como entrefolhas entre superfícies duras e não compressíveis, tais como superfícies de folhas ou placas feitas de vidro, metal, tais como aço, policarbonato e/ou poli(metacrilato de metilo). As películas podem ser gravadas em relevo e/ou podem incluir uma camada de núcleo expandida com uma pluralidade de micro-vazios. Em particular, as películas podem incluir uma poliolefina, um peso de base entre cerca de 30 gsm e cerca de 70 gsm, uma espessura em relevo entre cerca de 150 mícrons e 800 mícrons, e uma rigidez entre cerca de 150 gramas e cerca de 750 gramas, de acordo com o Teste de Rigidez à Flexão Circular.
