Abstract

Disclosed are compositions, methods, and uses for multi-layered films which are intended to provide high quality sealants having sufficient sealing strength for use in packaging and other applications while being more cost-effective and higher-yield than traditional combinations of unoriented polyolefin films and web materials. The film comprises a multilayer structure of LLDPE having a core layer, a surface skin layer, and a sealant skin layer. The core layer further comprises a slip agent, while the skin layers further comprise antiblock agents. Optional embodiments may include tie layers between the core layer and the skin layers, or may include pigments in one or more of the core layer or tie layers. The surface skin layer may be subjected to a surface treatment (e.g., corona treatment) to improve suitability for coating or metallization.
