Abstract
Film structures, packages, films and methods of making the same are provided wherein the film structures have a desiccant material incorporated into at least one layer of the film structures and further wherein the film structures can comprise a material for making a peelable seal when the film structures are heat sealed to other film structures. The film structures are utilized for a package to hold a product that may be sensitive to the presence of moisture. The product may preferably be pharmaceutical products, nutraceutical products, or devices such as absorbable sutures or medical stents, although any moisture-sensitive product is contemplated by the present invention.
