Description
Technical Field
The utility model relates to the field of packaging technology, specifically a waterproof canned type valve bag of leak protection powder.
Background
The valve bag is a material packing tool, plays an important role in the storage and transportation process of materials, and is high in efficiency, accurate in metering and low in labor investment due to the fact that automatic filling is adopted, so that the valve bag is widely used. The bag bottom seal of the existing valve bag is fixed by the folded bag body bottom by adopting a suture, the connection strength is general, when a heavier powdery object is loaded, the bearing performance of the bag bottom seal is poor, powder is easy to leak, water and moisture are present on some ground, the bag bottom is also easy to be affected with damp, so that the material quality in the valve bag is influenced, and in the carrying process, the situation that the bag opening is placed downwards also happens occasionally, so that the problem that the bag opening is easy to leak powder and damp also exists. Therefore, it is necessary to provide a powder-leakage-proof and water-proof sealing type valve bag to solve the above-mentioned problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a waterproof canned type valve port bag of leak protection powder to the problem that the current valve port bag that proposes leaks powder easily and wets among the above-mentioned background art of solution.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a waterproof canned type valve bag of leak protection powder, seals at the bottom of bag body, a feeding section of thick bamboo and bag, a feeding section of thick bamboo is formed by folding the making up in bag body top, seal at the bottom of the bag and form by folding the making up in bag body bottom, still include upper cover and lower seal, the upper surface sealing connection that upper cover passes through hot-pressure welding and a feeding section of thick bamboo to at the upper cover within range and the peripheral heat-seal seam that forms a plurality of, the bottom surface sealing connection that lower seal passed through hot-pressure welding and bag bottom and seal, and under the seal within range and the peripheral heat-seal seam that forms a plurality of down.
Further, the upper sealing layer and the lower sealing layer are PE plastic films.
Further, the width of the upper heat-sealing seam and the lower heat-sealing seam is 4-6 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses be provided with seal and lower seal respectively at the bag top of valve bag and bag end, greatly increased the intensity at the bag top and the bag end, in transportation and the storage process, no matter be the sack down or the bag end down, thereby the homoenergetic effectively prevents at the bottom of the bag or the bag top because of loading the emergence that leads to the damaged powder phenomenon of leaking that leads to leading to of heavier cause.
2. Go up the seal and pass through the last surface sealing connection of thermocompression bonding with a feeding section of thick bamboo to at last seal within range and peripheral formation a plurality of last heat-seal seams, the last heat-seal seam that is located seal periphery has further increased the sealing performance on bag top, can prevent effectively that the quality of material in the bag from leading to the fact the influence to the valve pocket when the bag top is down in transportation or the storage process, the last heat-seal seam that is located seal within range plays the strengthening rib effect, the intensity and the leakproofness on bag top have further been increased.
3. The bottom surface sealing connection that the back cover passes through hot pressure welding and bag bottom seal down to back cover within range and peripheral a plurality of heat-seal seams down that form under, the peripheral lower heat-seal seam that lies in the back cover has further increased the sealing performance at the bottom of the bag, can prevent effectively that moisture from getting into the valve pocket from the bottom of the bag and causing the influence to the quality of bag interior material in transportation or storage process, the lower heat-seal seam that lies in the back cover within range plays the strengthening rib effect, the intensity and the leakproofness at the bottom of the bag have further been increased.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a prior art valve bag construction;
in the figure: 1-bag body, 2-feeding cylinder, 3-bag bottom seal, 4-upper seal layer, 5-lower seal layer, 6-upper heat seal seam and 7-lower heat seal seam.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-2, the present invention provides an embodiment:
the utility model provides a waterproof canned type valve bag of leak protection powder, including the bag body 1, a feeding section of thick bamboo 2, seal 3 at the bottom of the bag, go up seal 4 and lower seal 5, a feeding section of thick bamboo 2 is formed by folding the making up in 1 top of the bag body, seal 3 at the bottom of the bag is formed by folding the making up in 1 bottom of the bag body, go up seal 4 and be connected through the upper surface sealing of a hot-pressure welding with a feeding section of thick bamboo 2, and form a plurality of last heat-seal seams 6 at last seal 4 within range and periphery, seal 5 is sealed the bottom surface sealing of 3 at the bottom of passing through hot-pressure welding and the bag down, and seal 5 within range and periphery under and form a plurality of heat-seal seams 7.
Go up seal 4 and seal 5 down and be the PE plastic film, go up seal 4 and seal 5's setting down, greatly increased the intensity at the bottom of bag top and the bag, in transportation and the storage process, no matter be the sack down or the bag bottom down, thereby the homoenergetic prevents effectively that bag bottom or bag top from leading to the emergence of the powder leakage phenomenon because of loading the heavy damage that causes.
