Abstract

The utility model relates to a moisture-proof packaging bag. The moisture-proof packaging bag comprises a bag body, the bag body adopts a double-layer structure with an inner bag and an outer bag, the outer bag is a multiple film woven bag, on the inner surface of which the multiple film moisture-proof layer is painted, and the inner bag is a moisture-proof plastic bag. The packaging bag comprises six surfaces, the combining parts of every two sides of the four sides of the inner bag and the outer bag are seamed together, a filling opening is arranged on the top surface, a discharging opening is arranged on the bottom surface; a belt is respectively seamed at the combining part between the side surfaces of the inner bag and the outer bag, a lifting lug is formed by the part where the belt is extended out of the top surface, and the length of the belt is equivalent to the height of the bag body. The moisture-proof packaging bag has the advantages of strong abrasion resistance, good moisture resistance, large volume, and strong bearing ability; the fastness of the inner bag and outer bag is fine; the product is easy to be assembled, and disassembled and piled up, and the moisture-proof packaging bag is suitable for the packaging and the transportation of the product of large ton grade.

Description

A kind of damp proof packing bag

(1) technical field

The utility model relates to a kind of damp proof packing bag.

(2) background technology

A lot of daily necessitiess and industrial products all have certain requirement to the humidity of environment, and just higher to the requirement of packing when ambient humidity is big, needing can be moistureproof.Present damp proof packing product category is various, but all is to take inside and outside double-ply structure mostly, moulds woven bag or paper and plastics compound bag as lining, perhaps realizes moisture-proof function at the internal layer coated with water blocking material of packaging bag.But these only limit to less product of packaging quality or short-distance transport, when a packaged products weight heavier (as more than half ton) or when needing long-distance transport, thereby this packaging bag just easily wearing and tearing influence moisture-proof function.

(3) summary of the invention

The purpose of this utility model is to provide a kind of damp proof packing bag, strengthens weight capacity, improves resistance to abrasion, strengthens moistureproof ability, is specially adapted to heavy packages and long-distance transport.

The technical solution adopted in the utility model is as follows:

A kind of damp proof packing bag comprises bag, and bag is the double-decker that comprises inner bag and outer bag, and outer bag is coated with the multiple film woven bag of multiple film moisture proof barrier for inside face, and inner bag is moistureproof plastic bag.

Though also be to have adopted double-decker, but outer bag itself is exactly in fact a four-layer structure, multiple film woven bag has guaranteed the resistance to abrasion of woven bag and has strengthened its moisture-proof function, and the multiple film moisture proof barrier that the woven bag inside face the applies anti-soak properties of enhanced package bag once more, add the moistureproof plastic bag in the outer bag, formed three layers of moisture proof barrier, promptly be used in the packing of large tonnage product or the transportation and wear and tear, packaging bag also can be well moistureproof.

Further, the damp proof packing bag is made stereo product, contain six, to increase the volume of packaging bag, the joint portion seam of inner bag with two two sides of four sides of outer bag bound together, packaging bag is soon made similar box-type, and inner bag and outer bag are fixed together, and can prevent that the inner bag interior generation of bag outside is more mobile.

Packing for the ease of powder product, filling exit can be set in packaging bag, filling exit may extend to filling exit place face part in addition by inner bag and outer bag and forms, it generally is the end face that filling exit is arranged on packaging bag, during can, the direct connection with the bottle placer outlet of the extendible portion of inside and outside bag got final product, after the can, earlier inner bag bundle bundle or other modes are isolated from the outside, and then outer bag is packaged.

Situation for a packaged products weight heavier (as more than half ton), during from filling exit taking-up product, difficulty is bigger, discharging opening can be set in packaging bag, operated by rotary motion is on the bottom surface of packaging bag, and discharging opening place inner bag is provided with the outer part of bag face that may extend to, behind the material of packing into, it is restrainted bundle get up, outer bag is provided with the bundle mouth.Inner bag may extend to the outer part of bag face makes material slowly to flow out, and also can directly dock with the material storage device inlet; The bundle mouth of outer bag is convenient to be equipped with the packaging bag stacking of product, and is more stable.

Further again, the face that packaging bag is provided with discharging opening is evenly to be provided with plural cross-under part on the bottom surface of packaging bag, can be with forming a not osed top bundle mouth after the rope cross-under once more, the degree of tightening by adjustment, one side plays the pressure of sharing the external bag bundle of product mouth in the packaging bag, also forms a cushion layer on the other hand when discharge hole for discharge.Described even setting is meant that the center with the bottom surface is radius settings such as the center of circle.

Further again, when the joint portion seam between inside and outside bag side is pricked, each place, joint portion all stitches to prick a belt body, the part that described belt body extends end face constitutes hanger, is convenient to utilize weight-lifting equipment to move packaging bag, and tape body length is not less than 1/2 of bag height, preferably suitable with the bag height, by increasing the connecting bridge of belt body and bag, prevent when mobile packaging bag, problems such as hanger disengaging bag, bag break take place.

Preferably, described damp proof packing bag constructions is as follows: contain six, the joint portion seam of two two sides of four sides of inner bag and outer bag binds together, end face is provided with filling exit, filling exit may extend to end face part in addition by inner bag and outer bag to be formed, and the bottom surface is provided with discharging opening, and discharging opening place inner bag has the part that may extend to outside the bottom surface, outer bag is provided with the bundle mouth, and this face also evenly is provided with plural cross-under part; Each seam of place, joint portion between inside and outside bag side is pricked the part that has a belt body, described belt body to extend end face and is constituted hanger, and tape body length is suitable with the bag height.

There is following advantage generally in the utility model:

The multiple film woven bag that employing is coated with multiple film moisture proof barrier is outer bag, and moistureproof plastic bag is the double-decker of inner bag, has strengthened the resistance to abrasion of outer bag; Multilayer moisture barrier has increased anti-soak properties.Make stereo product, volume is big, and inner bag is fixed well with outer bag; Product loading and unloading and stacking are convenient in the setting of filling exit and discharging opening; The cross-under part the weight capacity that has strengthened packaging bag is set; The reinforcement of the connecting bridge of belt body and bag has strengthened the fastness and the safety of packaging bag.Be specially adapted to the packing and the transportation of large tonnage product, better realized moisture-proof function on the whole and strengthened practicality.
