slot district

28 and 38 and cause gas leakage that a little place does not finish hot pressing.Usually to improve above-mentioned defective, can only be by precision machined mold design, the hot pressing lines of embossing/site is accomplished more meticulous, but so way will improve the mould price and make the cost increase because of need carry out accurate surface working, and might lose laborsaving characteristics of tearing again.

For this reason, the utility model proposes a kind of packaging bag of Improvement type, not only can avoid the air-tightness problem that produces because of involution unfairness in the manufacturing process but also can have the characteristics in joint power Kaifeng simultaneously, to improve above-mentioned defective.

For achieving the above object, packaging bag of the present utility model, it comprises: a bag, being coincided by two diaphragm materials forms; One Heat Sealing position is positioned at this bag periphery, forms a multi-turn formula embossing; One accommodation space is positioned at this bag, and this accommodation space is surrounded by this Heat Sealing position and forms; And one Kaifeng structure, be positioned at the zone outside this Heat Sealing position.

Preferably, these diaphragm materials are high molecule plastic or aluminium foil material.

Further, this Heat Sealing position is made up of at least 3 circulation embossings.

Between these circulation embossings successively a circle wrapping a circle.

Preferably, the distance of adjacent these circulation embossings is between 0.5 millimeter (mm)-2 millimeter (mm).

The live width thickness of these circulation embossings is between 0.1 millimeter (mm)-2 millimeter (mm).

Further, this Kaifeng structure is a straight line otch, and this linear incision extended line is by this accommodation space.

This Kaifeng structure is an involution holding area not.

This Heat Sealing position forms with this bag of pressing by hot pressing machine or hot pressing die.

Adopt the packaging bag of said structure, because this bag periphery has the Heat Sealing position to form an inner accommodation space of an osed top and a Kaifeng structure, this Heat Sealing position forms multi-turn formula embossing design, this splendid air-tightness of Heat Sealing position tool and also possess the characteristics that joint power is torn this Kaifeng mechanism, make packaging bag of the present utility model, can effectively solve the air-tightness problem that prior art produces because of involution unfairness in the manufacturing process.
