Abstract: A heavily calendered multiple component sheet is provided by calendering a multiple component nonwoven web formed from multiple component spunbond filaments under conditions that cause the lower-melting component to melt and flow into the interstitial spaces between the spunbond filaments. The calendered sheets are useful in child resistant packaging.

Abstract: An improved child-resistant blister package is provided in which the lidding component includes a tear-resistant nonwoven layer and a barrier layer. The nonwoven layer can be a melt-spun continuous filament nonwoven web or a flash spun plexifilamentary sheet. The lidding component used in peel off-push through blister packages of the invention contains fewer layers and has improved puncture resistance compared to lidding components used in child-resistant packages known in the art. In addition, in peel off-push through and peel-open package designs of the present invention, the lidding peels more cleanly from the blister component compared to packages known in the art which have a tendency to tear during peeling.
