Title
(EN) COMPOSITIONS OF ETHYLENE/ALPHA-OLEFIN MULTI-BLOCK INTERPOLYMER FOR ELASTIC FILMS AND LAMINATES
(FR) COMPOSITIONS D'INTERPOLYMÈRE MULTIBLOC ÉTHYLÈNE/ALPHA-OLÉFINE POUR FILMS ET STRATIFIÉS ÉLASTIQUES
Abstract
(EN)
This invention relates to polyolefin compositions. In particular, the invention pertains to elastic polymer compositions that can be more easily processed on cast film lines, extrusion lamination or coating lines. The compositions of the present invention preferably comprise an elastomeric polyolefin resin and a high pressure low density type resin.
(FR)
L'invention concerne des compositions polyoléfiniques. Plus particulièrement, l'invention concerne des compositions polymères élastiques pouvant être traitées plus facilement sur des lignes de coulage de feuilles minces, des lignes de laminage par extrusion ou des lignes d'enduction par extrusion. Les compositions de la présente invention comprennent de préférence une résine polyoléfinique élastomère et une résine de type basse densité haute pression.
