Laminates and packages produced therefrom

摘要

Laminates of a metal foil adhered to a water permeable layer by an adhesive which is softenable on exposure to water, and packages produced therefrom. Such packages have shown good child resistance due to the strength of the laminates which results from the presence of the adhered polymeric film. Despite the use of a water permeable film and a water softenable adhesive, sucking sealed blister packages has not been found to soften the adhesive sufficiently to allow the film to be removed from the metal foil.
