Since the infolding 4 is completely sealed. Thus, after packaging objects, the limit width of the opening 2 of the coat that need being sealed is reduced. The capper is easy to carry out the sealing process. Besides, since the infolding 4 part has four layers of jacket walls, the sealibility is excellent. The coat 1 and the coat bottom 3 are sealed after turned back, which increases the sealing intensity of the coat bottom 3.

Description

The vacuum packaging bag overcoat

The utility model relates to a kind of packaging bag overcoat.

At present, the vacuum packaging bag overcoat of commonly using mostly is the aluminium film greatly and makes, and running-on is two layers of jacket wall, when such two layers of jacket wall need are closed fully, because the restriction of capper is operated very inconvenient.

The purpose of this utility model is to provide a kind of capper sealing running-on vacuum packaging bag overcoat very easily.

In order to address the above problem, the technical solution of the utility model is: form along the invagination of running-on toward cover end direction at the dual-side place of overcoat, at the both sides at running-on place invagination difference seal closure, the running-on remainder opens wide, the whole seal closures in the cover end.

Further technical scheme of the present utility model is: cover end reverse reflex seal, overcoat is made for the aluminium film.

Good effect of the present utility model has: be formed with invagination in the overcoat both sides, the invagination complete closed, like this when having adorned packing material and sealed running-on of the present utility model, reduce the utility model running-on and needed the osed top finite width, capper is easy to carry out sealing operation, again, because flap section has four layers of jacket wall, sealing intensity is also higher.Reverse reflex seal at the bottom of the outer again condom has so also strengthened the sealing intensity at the cover end.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the utility model cover end 3 and the preceding structural representation of running-on 2 invaginations, 4 sealings;

Fig. 2 is the utility model structural representation.

Embodiment: referring to Fig. 1 and Fig. 2, a kind of vacuum packaging bag overcoat, overcoat 1 is made for the aluminium film, the aluminium film can against sunshine and waterproof, form along the invagination 4 of running-on 2 at the dual-side place of overcoat 1 toward the cover ends 3 direction, at the both sides invagination 4 difference seal closures at running-on 2 places, running-on 2 remainders open wide, the whole seal closures of the cover ends 3 reflexed.
