  • Chlorine-Free Packaging Sheet with Tear-Resistance Properties
    Publication number: 20150101741
    Abstract: A chlorine-free packaging sheet having a first rigid component, a second rigid component and a multilayer film positioned between the first rigid component and the second rigid component, a package comprising such packaging sheet and a method of manufacturing such sheet. The packaging sheet has a normalized combined tear initiation and propagation resistance in both the machine direction and the transverse direction of less than about 0.115 in*lbf/mil energy to break and less than about 0.800%/mil elongation, and a normalized tear propagation resistance in both the machine direction and the transverse direction of less than about 0.300 in*lbf/mil energy to break and less than about 0.145 lbf/mil peak load.
