  • Heat shrinkable polyethylene film and method for its manufacture
    Patent number: 4277594
    Abstract: Described is a mildly biaxially oriented, blown polyethylene film characterized by a cross directional (CD) shrink force in the range of about 60 to 300 psi, an average heat seal energy of at least about 2.0 in - lbs., an average internal tear resistance of at least about 30 gms/ply, and a minimum shrink temperature no higher than 220.degree. F. and which is less than crystalline melt point (or points) of polyethylene material. This film also has a shrink force in the machine direction (MD) which is typically in the range of about 200 to 300 psi.Also described is the process by which this film is produced.
