摘要：
Disclosed are methods, compositions, structures and uses for a biaxially oriented, multilayered film that may include a core layer comprising LLDPE, such as mLLDPE, wherein the core layer is flanked by a first skin layer and a second skin layer. This same type (e.g., melting index, density, and/or melting peak) of LLDPE, or different type(s) or blends thereof may be in the first skin layer and/or the second skin layer, wherein the first skin layer is located on a first side of the core layer, and the second skin layer is located on a second of the core layer, wherein the first side is on an opposite side of the core layer as compared to the second side. The biaxially oriented, multilayered film may have a sealing strength of at least 400 g/cm at 100° C. under a pressure of 41 N/cm2 at a dwell time of 0.75 s.
