Abstract
M UM MATERIAL FLUìVEL"<D>. A presente invenção fornece uma estrutura de película e um método para a sua produção, bem como embalagens formadas a partia camada de vedação de superfície de polímero catalítico de um único sítio, SCC ou metaloceno são su película de uma só camada desse polímero. A presente invenção fornece, em uma modalidade, uma película que tem pelo menos duas camadas para uso como um componente vedante em uma película de múltiplas camadas ou como uma película vedante em embalagens, a qual compreende uma camada de vedação de superfície e uma camada intensificadora da resistência de aderência a quente, sendo que a camada de vedação de superfície é um interpolímero de etileno catalítico de um único sítio (SSC) e uma ou mais C~ 3~-C~ 20~ alfa-olefinas que têm uma densidade na fíndice de fusão de cerca de 0,2 a cerca de 10 dg/ma resistência de aderência a quente da camada de vedação de superfície é selecionada a partir de copcatalítico de um único sítio e que não de um único sítio e as suas misturas, com uma densidade de pem índice de fusão de cerca de 0,2 a cerca de 20 dga camada de SSC e a camada intensificadora varia d
