Abstract
The invention is directed to a thermoplastic film package having one or more pouches for holding articles such as thermoplastic film bags, and a method of producing and filling such a package. The package is made from a thermoplastic film bag folded along horizontal and vertical fold lines such that a pouch having an open end is defined by the walls of the bag. It is non-permanently and non-destructively secured by adhesive tape or a selectively applied adhesive in the folded position such that the pouch can be used for storing articles. The entire thermoplastic film bag enclosure is accessible upon release of the non-destructive adhesive or tape and unfolding of the bag along the horizontal and vertical fold lines.
