Title (EN) AIR-PACKING DEVICE AND ITS MANUFACTURE METHOD
(FR) DISPOSITIF D’EMBALLAGE À AIR ET SON PROCÉDÉ DE FABRICATION
(ZH) 一种空气包装装置及其生产方法
Abstract: front page image
(EN)An air-packing device has an air-containing space which is formed by secondary thermoplastic sealing of two layers of thermoplastic films and comprises a plurality of independent sealed air chambers (3a, 3b) and a main passage (1). The main passage (1) has an air inlet (8). Each of the sealed air chambers communicates to the main passage (1) by means of a check valve (2) constituted by the two layers of films. Some of or all the air chambers are each provided with two or more than two check valves (2). A manufacture method of such air-packing device is also disclosed. The present invention can effectively reduce the volume of the air-packing device and therefore reduce its transport cost.
(FR)Un dispositif d’emballage à air comporte un espace contenant de l’air qui est formé par scellement thermoplastique secondaire de deux couches de films thermoplastiques et comprend une pluralité de chambres à air scellées indépendantes (3a, 3b) et un passage principal (1). Le passage principal (1) comporte une entrée d’air (8). Chacune des chambres à air scellées communique avec le passage principal (1) au moyen d’un clapet de non-retour (2) constitué par les deux couches de films. Certaines ou toutes les chambres à air sont dotées de deux clapets de non-retour (2) ou plus. Un procédé de fabrication d’un tel dispositif d’emballage à air est également décrit. La présente invention peut réduire efficacement le volume du dispositif d’emballage à air et réduire par conséquent son coût de transport.
