摘要
The present invention is directed to a heat-shrinkable, thermoplastic film or bag which contains at least one homogeneous ethylene alpha-olefin copolymer with at least some limited long chain branching. Oriented films made in accordance with the present invention exhibit improved processability as well as improved physical properties such as excellent optics and impact resistance. A homogeneous ethylene alpha-olefin with long chain branching may be present in a monolayer film either alone or in a blend or may be included in one or more layers of a multilayer film in accordance with the present invention.
