Abstract

Patente de Invenção: <B>"FOLHA DE POLIPROPILENO SELáVEL A QUENTE, ESTIRADA, DE VáRIAS CAMADAS COM CAMADA DE BLOQUEIO DE GáS DE POLICETONA"<D>. A presente invenção refere-se a folhas compostas seláveis a quente de uma folha de polipropileno estirada biaxialmente como folha básica, uma camada de transmissor de aderência de poliolefina modificada, uma camada de bloqueio de gás de um copolímero de etileno e monóxido de carbono e uma camada de selagem a quente de polímeros de olefina, sendo que a folha básica porta pelo menos sobre uma superfície uma combinação de camadas orientada eventualmente pelo menos monoaxialmente, que se compõe de: A) uma camada externa selável a quente de um homo-, co- ou terpolímero olefínico; B) uma camada de transmissor de aderência de poliolefina modificada; C) uma camada de bloqueio de gás de um copolímero de uma ou várias olefinas e monóxido de carbono (policetona); D) uma camada de transmissor de aderência de poliolefina modificada e E) uma camada de poliolefina e de um polímero de etileno com pelo menos 3% em peso de etileno, a folha básica porta sobre pelo menos uma de suas superfície, eventualmente, uma camada A, uma combinação de camadas A até E, A até D ou B e C.Invention Patent: <B> "HOT SEALABLE POLYPROPYLENE SHEET, DRAWN FROM VARIOUS LAYERS WITH POLYCETONE GAS LOCK LAYER" <D>. The present invention relates to heat sealable composite sheets of a biaxially stretched polypropylene sheet as the base sheet, a modified polyolefin adhesion transmitter layer, a gas blocking layer of an ethylene and carbon monoxide copolymer and a heat sealing layer of olefin polymers, the base sheet having at least on one surface a combination of layers possibly oriented at least monoaxially, which consists of: A) a heat sealable outer layer of a homo-, co - or olefinic terpolymer; B) a modified polyolefin adhesion transmitter layer; C) a gas blocking layer of a copolymer of one or more olefins and carbon monoxide (polyketone); D) a layer of modified polyolefin adhesion transmitter and E) a layer of polyolefin and an ethylene polymer with at least 3% by weight of ethylene, the base sheet bears on at least one of its surfaces, possibly a layer A, a combination of layers A through E, A through D or B and C.
