Abstract: A bag for vacuum sealing which has a bag body composed of a first sheet 11 and a second sheet 12, which have thermally fusible synthetic resin films 11a and 12a on at least the respective inner surfaces, and a non-woven fabric 15 which is a gas-permeable fiber structure formed of thermally fusible fibers. The sheets 11 and 12 are thermally fused together at both sides a and a lower side b, and the unfused upper side becomes an open side 13 of the bag body. The non-woven fabric 15 is bonded or fused with the inner surface of either one of the sheets 11 and 12. Food, clothing or the like is put in a space 16 between the sheet and the non-woven fabric 15, and air is extracted from the interior of the bag body through the open side 13. The open side 13 is thermally sealed in the portion with a width between “c” and “c”.

Abstract: A suction nozzle for use in a compressive preservation bag that is made of air-impermeable synthetic resin material includes a check valve made of synthetic resin material at a portion thereof. The suction nozzle includes an elongated body having an insertion section that has a flattened, substantially cylindrical shape and is tapered so as to be inserted into the check valve. The insertion section of the body has a plurality of openings communicating with the inside of the body.
