Concrete mode of the present utility model is as follows：

A kind of reinforcement type moisture proof Openmouthed bag, including bag body, the bag body includes being arranged on the protection against the tide of inside The adhesive layer of layer, the carrier layer being wrapped in outside damp-proof layer and the connection damp-proof layer and carrier layer；

The carrier layer is formed by connecting into straight-tube shape, bottom lock, surrounding and the stack shell of bottom by suture, and top is provided with It is open；

Back-up coat is additionally provided with outside the carrier layer bottom, the back-up coat is wrapped up suture.

Accordingly, damp-proof layer causes Openmouthed bag to have humidity resistance, and adhesive layer causes the connection between damp-proof layer and Openmouthed bag More tight and firm, adhesive layer has been provided with itself one layer of intensity, further improves the intensity of Openmouthed bag.

The suture of the bottom surrounding of carrier layer is easiest to first rupture, therefore is provided with back-up coat, back-up coat in suture Suture is wrapped up, the intensity of Openmouthed bag is improve.

Used as the preferred of such scheme, the bottom of the carrier layer is extended at the two ends of the back-up coat, and two ends are prolonged respectively Stretch out 50～60mm.Accordingly, its back-up coat completely wraps suture, can more improve the intensity of Openmouthed bag, and two ends are extended 50～60mm is easy to plus man-hour operation and cutting, prevents uncontrollable in production cutting.

Used as the preferred of such scheme, the back-up coat is mainly by with plasticity, the especially material of toughness, brown paper structure Into.

Used as the preferred of such scheme, the damp-proof layer is provided with open into straight-tube shape, bottom lock, top, bottom and cylinder Body is adhered on a carrier layer by adhesive layer.

Used as the preferred of such scheme, the open of the damp-proof layer extends the open of carrier layer, and higher than the carrier Layer it is open.

Accordingly, open height of the open height of damp-proof layer higher than carrier layer so that in charging, can be by damp-proof layer It is open to turn up, stop that impurity is entered in interlayer when being easy to fill material.

Used as the preferred of such scheme, the damp-proof layer is mainly made up of the film with humidity resistance, mainly adopts PE films.

Used as the preferred of such scheme, the carrier layer is mainly made up of natural material, especially paper.

Used as the preferred of such scheme, the carrier layer has upright bottom, preferred X-shape bottom or plinth.According to This, Openmouthed bag is capable of achieving uprightly after charging, is easy to pack, carries.

Used as the preferred of such scheme, the upright bottom includes the two trapezoidal sealed pieces for folding and two rectangles Sealed piece, described two trapezoidal sealed pieces and two rectangle sealed pieces mutually overlap bonding.

Used as the preferred of such scheme, the adhesive layer adopts thermal viscosity material, and especially rubber is constituted.Accordingly, bond Layer is not only tightly connected damp-proof layer with carrier layer, and also improves the intensity and toughness of Openmouthed bag itself, improves open The firmness of bag.

The utility model has the advantages that：

1st, Openmouthed bag of the present utility model has firmness that is moistureproof, improve Openmouthed bag, prevents miscellaneous when charging Matter is entered in interlayer；

2nd, Openmouthed bag is capable of achieving uprightly after charging in the utility model, is easy to pack, carries；

3rd, the suture of the bottom surrounding of carrier layer is easiest to first rupture in the utility model, therefore is provided with suture Back-up coat, back-up coat is wrapped up suture, improves the intensity of Openmouthed bag.
