PROBLEM TO BE SOLVED: To provide a package re-sealable many times without any need of breaking a package material and any drop in a sealing function. ;SOLUTION: A label 6 for a re-sealable package 1 is formed to have an application side 8 with self-pressure sensitive adhesive layer 20 spread thereon for obtaining the preset adhesive strength applicable to the surface 7 of the re-sealable package 1. Also, the application side 8 is silicone processed in such a way as keeping adhesive strength with the adhesive layer 20 at a value less than the prescribed strength. The adhesive layer 20, after applied, moves to the application surface 7 of the package 1 and a danger of opening the re- sealable package 1 is thereby eliminated.;COPYRIGHT: (C)1996,JPO
