PROBLEM TO BE SOLVED: To provide a reclosable bag wherein its unsealing can be visually recognized until the bag is intentionally unsealed, contents are free from fear of slipping down if an adhesive seal shifts in position, and the bag once unsealed can be easily opened/closed by a one-touch operation. SOLUTION: Two strong and weak adhesive bands 31 and 32 with different adhesive strength are provided in the vicinity of the bag opening of a bag body 1 or a flap 2. Until the bag is unsealed for the first time, sealability is kept by the adhesion of the strong adhesive band 32. The strong adhesive band 32 is cut off from perforations 5 provided between both adhesive layers when the bag is first unsealed. The reclosable bag is sealed only by the adhesion of the weak adhesive band 31. COPYRIGHT: (C)2004,JPO
