FIELD: sealing.
SUBSTANCE: re-closing packing contains a cold sealer, formed between the first and the second sealing divisions and seals the packing in the original not opened state. Thereby, bonding strength of the cold sealer and the first and second sealing divisions is higher, than bonding strength inside of the cold sealer, so when the seam is opened, the cold sealer is divided, partially sticking to the first sealing division and partially sticking to the second sticking division. Thereby, the cold sealer also seals the packing in a subsequently opened state. Whereas sealing strength in the subsequently opened state is less than the original sealing strength.
EFFECT: creation of a re-closing packing, the re-closing qualities of which are improved.
