Abstract
A shrinkable-stretchable polymeric laminated structure is made up of a shrink-stretch film on the outside and a nonwoven on the inside, with or without an adhesive. Preferably the film, nonwoven and adhesive are made from the same polymer family, including copolymers, which renders the laminate 100% recyclable. The film, nonwoven, and adhesive are modified to provide different responses to heat in addition to controlled water vapor permeability. The structure allows for water vapor permeability in one direction (inside-to-outside) and not in the opposite direction to allow wrapped article to dry or to keep wrapped articles dry and prevent corrosion related damage.
