Abstract
A process for making an internally-reinforced bag assembly includes formation of an outer bag body with a plurality of longitudinally oriented, laterally spaced pleats or tucks therein. An inner reinforcement layer is applied to the outer bag body after formation of the pleats, whereby the inner layer spans and overlaps each of the pleats. An apparatus embodying the present invention effects bag formation in this fashion. Advancement through the forming apparatus effects formation of the outer web into a gusseted tube, and formation of a square bottom seal. The completed bag assembly includes the inner reinforcement layer, which is dimensioned to define a circumference which is less than a circumference defined by the bag body. The resultant bag assembly resists bulging and deformation under the influence of particulate, granular, or other flowable products packaged therein.
