Title (EN) MULTILAYER FILMS AND LAMINATES CONTAINING SLIP AGENTS
(FR) FILMS MULTICOUCHES ET STRATIFIÉS CONTENANT DES AGENTS GLISSANTS
Abstract:
(EN) The coextruded multilayer film has at least two layers, including a sealant layer and a second layer in contact with the sealant layer. The sealant layer contains (A) a first ethylene-based polymer having a density from 0.865 g/cc to 0.930 g/cc and a melt index from 0.5 g/10 min to 25 g/10 min; (B) an unsaturated primary fatty acid amide having a melting point of 100℃or less;and (C) a saturated primary fatty acid amide having a melting point greater than 100℃.The unsaturated primary fatty acid amide and the saturated primary fatty acid amide have a weight ratio of from 3: 1 to 1: 6. The second layer contains a second ethylene-based polymer. The present disclosure also provides a laminate containing said sealant layer.
(FR) Le film multicouche coextrudé comprend au moins deux couches, comprenant une couche d'étanchéité et une seconde couche en contact avec la couche d'étanchéité. La couche d'étanchéité contient (A) un premier polymère à base d'éthylène présentant une densité de 0,865 g/cc à 0,930 g/cc et un indice de fusion de 0,5 g/10 min à 25 g/10 min; (B) un amide d'acide gras primaire insaturé présentant un point de fusion de 100 °C ou moins; et (C) un amide d'acide gras primaire saturé présentant un point de fusion supérieur à 100 °C. L'amide d'acide gras primaire insaturé et l'amide d'acide gras primaire saturé présentent un rapport de poids de 3:1 à 1:6. La seconde couche contient un second polymère à base d'éthylène. La présente invention concerne également un stratifié contenant ladite couche d'étanchéité.
