Zusammenfassung:	The present disclosure provides for a multilayer film having a sealant layer and a first layer, where the first layer is formed from a first polyolefin composition, and a laminate that includes the multilayer film. The first polyolefin composition of the first layer consists essentially of a high density polyethylene (HDPE) resin and a propylene-ethylene copolymer thermoplastic elastomer (TPE). In addition to the first layer of the first polyolefin composition and the sealant layer, the laminate also includes a substrate film and an adhesive layer comprising polyurethane in adhering contact with the substrate film and the first layer, where when the adhesive layer is formed from a solvent-free adhesive the adhesive layer has an elastic modulus of greater than 25 MPa, and when the adhesive layer is formed from a solvent- based adhesive the adhesive layer has an elastic modulus of greater than 0.30 MPa, the elastic modulus being measured for the polyurethane in accordance with ASTM D412. La presente descripción proporciona una película multicapa que tiene una capa selladora y una primera capa, donde la primera capa se forma a partir de una primera composición de poliolefina y un laminado que incluye la película multicapa. La primera composición de poliolefina de la primera capa consiste esencialmente en una resina de polietileno de alta densidad (HDPE) y un elastómero termoplástico (TPE) de copolímero de propileno-etileno. Además de la primera capa de la primera composición de poliolefina y la capa selladora, el laminado también incluye una película de sustrato y una capa adhesiva que comprende poliuretano en contacto adherente con la película de sustrato y la primera capa, donde, cuando la capa adhesiva se forma a partir de un adhesivo sin disolvente la capa adhesiva tiene un módulo elástico superior a 25 MPa, y cuando la capa adhesiva se forma a partir de un adhesivo a base de disolvente, la capa adhesiva tiene un módulo elástico superior a 0.30 MPa, donde el módulo elástico se mide para el poliuretano según la norma ASTM D412.
