Abstract
<B>MISTURAS, PROCESSOS E FILMES POLìMERICOS RESISTENTES à PERFURAçãO, sendo uma mistura de polímeros e filmes mono e multi-camadas, assim feitos adequados para o processamento e embalagem de artigos os quais tais filmes possuem uma combinação melhorada de propriedades e.g., tais como menor resistência à ruptura e maior resistência à perfuração, ou maior resistência à perfuração em ambas as temperaturas tanto do ar ambiente como em alta temperatura em contato com a água, onde a mistura preferivelmente possui um primeiro copolímero de etileno e hexeno-1 possuindo um ponto de fusão do copolímero de 80 a 98°C, preferivelmente de 80 a 92°C; um segundo copolímero de etileno e ao menos uma <244>-olefina possuindo um ponto de fusão do copolímero de 115 a 128°C; e um terceiro copolímero de etileno e um vinil éster ou alquil acrilato e possuindo um ponto de fusão de 60 a 110°C, e um processo para a fabricação de tais filmes, especialmente filmes encolhíveis possuindo ao menos 40% de encolhimento a 90°C e ao menos uma direção.<B> MIXTURES, PROCESSES AND POLYMERIC FILMS RESISTANT TO DRILLING, being a mixture of polymers and mono and multi-layer films, thus made suitable for the processing and packaging of articles which such films have an improved combination of properties eg, such as less resistance to rupture and greater resistance to perforation, or greater resistance to perforation at both ambient air temperature and high temperature in contact with water, where the mixture preferably has a first ethylene and hexene-1 copolymer having a point melting of the copolymer from 80 to 98 ° C, preferably from 80 to 92 ° C; a second ethylene copolymer and at least one <244> -olefin having a copolymer melting point of 115 to 128 ° C; and a third copolymer of ethylene and a vinyl ester or alkyl acrylate and having a melting point of 60 to 110 ° C, and a process for the manufacture of such films, especially shrink films having at least 40% shrinkage at 90 ° C and at least one direction.
