Bag with bendable retainer strip, and method of making the same

A method of making a bag of the type having opposed first and second bag walls with their opposite side edges sealed to one another in respective sealed areas adjacent each of such side edges and their bottom edges sealingly attached to one another to provide a bag having a top bag mouth opening, the method comprising:

• providing said first bag wall with a substantial portion projecting substantially upwardly as a lip above said second bag wall and thereby above said bag mouth opening;
• securing a bendable retainer strip to extend across said lip;
• forming a clearance indentation in each of such sealed side edges of said bag to extend into but not beyond such sealed area and further extending from adjacent to the lower edge of said lip downwardly to a substantial distance below said bag mouth opening, thereby to define an end tab extension at each opposite end of said lip;
• and thereby providing opposite end tab extensions of said lip including said strip projecting into overhanging relation to said indentations, and providing each of said extensions with a tip end which is in alignment with the adjacent said side edge, so that said lip is adapted to be folded over into closing relation to said bag mouth opening and onto the outer face of said second wall, and said end tab extensions being then adapted to be bent over within said clearance indentations onto the outer face of said first wall for maintaining said bag closed, but permitting said bag to be reopened by bending said tab extensions out of engagement with said first wall and unfolding said lip away from said bag mouth opening.
