D, by two layers of unidirectional air valve inner membrance top end face and two-layer gas flush packaging external film top end face, heat-sealing pressing.
In described processing step c, be by heat seal die line through the external mould of gas flush packaging on multiple ink circulates or seamless pattern position, form the Intake Open of inflatable region and begin to speak.
In described processing step c, the mode arranged with front and back, arranges longitudinal heat seal die line and forms inflation inlet in the front end of inflatable region, the heat seal die line arranging another longitudinal direction in the rear end of inflatable region is closed.
Below in conjunction with specific embodiment, the technical solution of the utility model is explained in detail.
Gas flush packaging body of the present utility model comprises: the plastic sheeting of two layer high-barriers is as the external film 11,12 of gas flush packaging; The Non-return air valve film 21,22 adopting two layers of plastic to make combines as gas flush packaging body inner membrance, wherein one deck Non-return air valve film 21 or Non-return air valve film 22 print single or double containing multiple intervals square or polygonal ink circulates or seamless pattern a, the ink logo a of printing contains but other pattern a of the side's of being not limited to ladder type, and wherein one deck ink logo is between two layers of unidirectional air valve film 21,22.Gas flush packaging body comprises by two layers of unidirectional air valve film 21,22 top end face and two-layer gas flush packaging external film 11,12 top end face.
Wherein the external film of one deck gas flush packaging 11 or the external film 12 of gas flush packaging will press together formation finished product with two layers of unidirectional air valve film 21,22 by heat seal die line 34, form multiple tap air channel c.
By heat seal die line 31,32,33,35,36,37,38, the external film of other one deck gas flush packaging 11 or the external film of gas flush packaging 12 are pressed together with described finished product again, formed containing many independent gas column gas flush packaging bodies, and be pressed on multiple ink circulates pattern a by heat seal die line 33 and packaging body be divided into inflatable region 50 and gas storage room 40 two parts.
Two layers of unidirectional air valve inner membrance 21,22 and the external film of two-layer gas flush packaging form filling channel 50 by between heat seal die line 31,33, and filling channel 50 is between two layers of unidirectional air valve film 21,22; Form inflation inlet 50a by heat seal die line 36 in filling channel 50 one end, by heat seal die line 32, filling channel 50 other one end by filling channel 50 is closed.
Two layers of unidirectional air valve film 21,22 and the external film of two-layer gas flush packaging 11,12 are pressed on multiple ink circulates pattern a position by heat seal die line 36 through adventitia, form the passage opening 50d of inflatable region 50.
Two layers of unidirectional air valve inner membrance 21,22 and the external film of two-layer gas flush packaging 11,12 are pressed on multiple ink circulates pattern a by heat seal die line 33, form multiple admission port b.
Gas flush packaging body is divided by the heat seal die line 33,35,37 of longitudinal direction and horizontally set and forms multiple independently gaseous storage room 40; Form corner by the heat seal die line 38 of bottom, gaseous storage room 40 and seal node position.
Multiple tap air channel c one end communicates with admission port b, and one end to communicate with gaseous storage room 40 as giving vent to anger, and the shape of multiple tap air channel c is not limited to diagram bulletin shape, also may various form.When filling channel 50 is inflated, two layers of unidirectional air valve film 21,22 and the external film 11,12 of two-layer gas flush packaging expand simultaneously, air does not need through filling channel to contact in situation with adventitia, directly automatically, enter gaseous storage room 40 through admission port b, after inflation completes, can automatically be remained silent immediately by the characteristic of self, locking gas backstreaming, and pressure reaches best effect of holding one's breath with it, without the need to sealing after inflation again.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
