PROBLEM TO BE SOLVED: To provide a synthetic resin bag which is improved in adhesive strength of a releasable adhesive band layer located under a chuck, facilitates separation of the same on the side of an opening portion, and prevents the adhesive band layer from separating from the inside of the bag body. SOLUTION: The synthetic resin bag body 1 has the openable chuck 3 arranged in the opening portion 2, and a sealing means formed of the releasable viscous band layer 4, arranged under the chuck 3 in parallel with the same. Herein one side edge of the viscous band layer 4 close to the chuck 3 is formed like a zigzag shape obtained by continuously staggering a viscous area 5 and a non-viscous area 6. Thus the releasable force of the viscous band layer 4 is weakened on the side of the opening portion while it is strengthened on the inside of the bag body. COPYRIGHT: (C)2007,JPO&INPIT
