Title:
MULTILAYER STRUCTURES AND ARTICLES COMPRISING THE SAME
Document Type and Number:
WIPO Patent Application WO/2017/000339
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to multilayer structures and articles formed therefrom. In one aspect, a multilayer structure comprises (a) a biaxially oriented polyethylene film comprising a linear low density polyethylene having a density of 0.910 to 0.940 g/cm3, wherein the ultimate elongation in the machine direction of the biaxially oriented polyethylene film is at least 2 times greater than the ultimate elongation in the cross direction, and wherein the ultimate tensile strength of the biaxially oriented polyethylene film is at least 60 MPa in at least one of the machine direction and the cross direction; (b) an adhesive layer; and (c) a sealant film, wherein the ultimate elongation of the sealant film is at least 300%in at least one of the machine direction and the cross direction, wherein the ultimate tensile strength of the sealant film is less than 50 MPa in at least one of the machine direction and the cross direction, and wherein the sealant film has a heat seal initiation temperature of 105℃or less; wherein the sealant film is laminated to the biaxially oriented polyethylene film by the adhesive. In some embodiments, the sealant film comprises at least one layer comprising at least 30 percent by weight of a polyolefin plastomer, a polyolefin elastomer, an ultra low density polyethylene, an ethylene acetate copolymer, an ethylene acrylic acid copolymer, or an ethylene acrylate copolymer.
