<p>A pouch (10) comprises two opposed webs (12, 14) having respective side and bottom portions (16, 18, 20) sealed together thereby leaving an unsealed end (22) whereat one (12) of the opposed webs extends beyond the free edge (24) of the other (14) of the opposed webs to form a flap (26). The flap (26) is foldable onto over an edge portion of the other web. An area of pressure sensitive adhesive (28), which is disposed on the flap (26), extends through a position for normal folding of the flap (26), so that the flap (26) is foldable within the area covered by the adhesive to bring that latter into direct sealing contact at the flap fold. <??>The flap (26) is foldable along a rupturable portion (30) which extends across the width of the flap (26). The relatively readily rupturable portion (30), which defines a fold line (32), comprises a perforated line of weakness or a scored line of weakness. </p> |
