Abstract

Provided are heat sealing, barrier laminates including polyethylene. The laminates can be adhesiveless and fully compatible with polyethylene recycling streams. They can exhibit improved, maintained, or desirable properties in comparison to existing laminate structures that are not fully compatible with polyethylene recycling streams. The laminate comprises a multilayer film and an oriented film. The oriented film is thermally laminated to the outer layer of the multilayer film to provide the laminate.
