Chlorine-free packaging sheet with tear-resistance properties

摘要

A chlorine-free packaging sheet having a first rigid component 61, a second rigid component 63 and a multilayer film 92 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*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.
