ABSTRACT:
A composite bag for crusted bread products is disclosed comprising a first portion in the form of a paper bag having a closed end and an open end, and a second portion of plastic film material bonded to and extending from the open end of the paper bag and providing a closable opening for the composite bag. The second portion is defined by sheets of plastic film having different lengths longitudinally with respect to the open end of the paper bag and bonded to the paper bag for one of the films to extend longitudinally beyond the other and provide an extension flap which facilitates supporting the bag during insertion of a bread article thereinto. The composite bag is produced by transferring a preformed paper bag laterally with respect to the axis thereof between plastic sheets which are bonded to the open end of the bag and then longitudinally seamed along lines contiguous with side edge folds of the paper bag.
