ABSTRACT:
A package of imbricated bags is provided that is adapted for dispensing and opening such bags one at a time. The package includes a chain of adhesively imbricated bags in overlying sequence, each bag being adhesively but releasably attached to adjacent bags and having an open mouth end directed toward the leading end of the chain, and a container for the chain having an elongate, constricted opening through which the leading end of the chain is directed. The length of the opening is less than the bag chain width by a selected extent sufficient to cause the mouth of each bag to open in response to transverse constriction as the chain is advanced through the opening, provided that the width of the opening is sufficiently narrow so as to resistively confront the lower edge of the mouth of a bag being pulled through the opening. A method for making the bag package is also provided.
