A paper bag having an inner ply and an outer ply with lines of perforations in the outer ply defining a flap adapted to be pulled back to open the bag, the inner ply having a transverse line of perforations underneath the flap, the plies being releasably adhered together by pressure-sensitive adhesive forward of the inner ply line of weakness and permanently adhered together rearward of the inner ply line of weakness, whereby after the bag has been filled and closed, the bag may be opened by pulling back the flap to tear the inner ply open rearward of the inner ply line of weakness and re-closed by adhering the flap to the inner ply forward of the inner ply line of weakness.

A bag having opposed walls, a bottom closure, an open mouth, an inner ply, and an outer ply, the outer ply of one of said walls having a pair of lines of weakness extending from the mouth edge of said one of said walls in spaced relation to one another defining a closure flap adapted to be opened by grasping the outer ply at said edge and pulling it back to tear the closure flap away from the outer ply at said lines of weakness, the inner ply of said one of said walls having a line of weakness underneath said closure flap extending between said outer ply lines of weakness spaced back from said mouth edge of said one of said walls said plies being permanently adhered together rearward of said inner ply liine of weakness for tearing open of a portion of the inner ply rearward of said inner ply line of weakness on pulling said closure flap back, and said plies being releasably and resealably adhered together forward of said inner ply line of weakness by pressure-sensitive adhesive, whereby after the bag has been filled and closed it may be opened by pulling away said closure flap, the latter separating from the inner ply as enabled by the pressure-sensitive adhesive back to the inner ply line of weakness, and then tearing the inner ply at and back from the line of weakness to form an opening in the bag for removal of the contents of the bag, the flap being adapted to be re-adhered to the inner ply by the pressure-sensitive adhesive to close said opening.
