Polyethylene film compositions, laminates, and methods for making the same

Abstract

Disclosed are transparent films having a core comprising at least 50 wt. % high-density polyethylene and, optionally, 50 wt. % or less of linear low-density polyethylene. Further, the transparent films may have a printable skin layer adjacent to a first side of the core, wherein the printable skin layer may comprise, consists essentially of or consists of linear low-density polyethylene or ethylene-propylene copolymer. Further, the transparent films may have a skin layer adjacent to a second side of the core, wherein the skin layer may comprise, consists essentially of or consists of linear low-density polyethylene or ethylene-propylene copolymer. Further still, the transparent films may be oriented in at least one direction and have a directional modulus of at least 1200 MPa. Such transparent films may be laminated to a laminating substrate, such as a biaxially oriented polyethylene single or multilayer film, to produce a laminated film with remarkable sealing and integrity.
