Abstract
The utility model provides a kind of biplate PE films protection against the tide venting bags, improves the overall air permeability of sack, ensures the quality of material-filling process and links up；Meanwhile after material-filling stacking, it can effectively avoid the entrance of external humidification air; so as to which material in protective bag, including valve bag bag body, the valve bag bag body are provided with outer wall, inwall and intermediate course; the outer wall and inwall are brown paper, and the intermediate course is PE films, it is characterised in that：If the intermediate course includes dry plate PE films, the edge of the PE films is overlapped.Connected between PE films by the way of overlapping, improve the overall air permeability of sack, ensured the quality of material-filling process and link up, while reduce the quick-fried bag problem caused by gas permeability.Connected mode is simple between PE films, reduces processing cost.After material-filling stacking, the entrance for together, avoiding external humidification air is tightly pressed at after PE films are overlapped, so as to which material makes moist in protective bag.
Description
Technical field
It the utility model is related to valve bag technical field, and in particular to biplate PE film protection against the tide venting bags.
Background technology
Valve bag, it is commonly called as being sticking bag, is current international popular packaging bag, is fed from top or bottom valve port, using special
Filling apparatus, cube is dressed up after filling material, heap bag is neat, attractive in appearance, belongs to Environmental protection bag.
At present, it is desirable to which valve bag has moistureproof and ventilative property simultaneously, and most of is mortar paper bag, such as glue for tile
Deng because material contains gas in pouring process, sack must have gas permeability, fill while be vented, can just be filled to mark
Quasi- weight.During storage and transport, it is necessary to have the moisture resistance of height, just can guarantee that the material in sack will not be tied
Block, avoiding, which influences client, uses, and has certain bottleneck for current technology.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of biplate PE films protection against the tide venting bags, and it is whole to improve sack
The air permeability of body, ensure the quality of material-filling process and link up；Meanwhile after material-filling stacking, it can effectively avoid outside tide
The entrance of humid air, so as to material in protective bag.
A kind of biplate PE films protection against the tide vapor-permeable type valve bag, including valve bag bag body, the valve bag bag body be provided with outer wall,
Inwall and intermediate course, the outer wall and inwall are brown paper, and the intermediate course is PE films, it is characterised in that：In described
If interlayer includes dry plate PE films between, and the edge of the PE films is overlapped.
More preferably to realize the utility model, may further be：The intermediate course includes PE films described in two panels, when described
After the internal filler of valve bag bag, the valve bag bag body is square, and the lap of the two panels PE films is close to the valve bag
At the middle separated time of bag body side surface.
The beneficial effects of the utility model：Connected between PE films by the way of overlapping, improve the ventilative of sack entirety
Degree, ensure the quality of material-filling process and link up, while reduce the quick-fried bag problem caused by gas permeability.Connect between PE films
It is simple to connect mode, reduces processing cost.After material-filling stacking, it is tightly pressed at together, is avoided outer after PE films are overlapped
The entrance of portion's humid air, so as to which material makes moist in protective bag.
Brief description of the drawings
Fig. 1 illustrates sectional structure chart of the present utility model；
Fig. 2 illustrates the structural representation of the utility model side wall.
In figure, 1 is outer wall；2 be intermediate course；3 be inwall；21 be the overlay region of PE films.
Embodiment
The utility model is elaborated below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2：A kind of biplate PE films protection against the tide vapor-permeable type valve bag, including valve bag bag body, the valve bag
Bag body is provided with outer wall, inwall and intermediate course, and the outer wall and inwall are brown paper, and the intermediate course is PE films, its
It is characterised by：If the intermediate course includes dry plate PE films, PE films specially described in two panels, the edge phase mutual respect of the PE films
It is folded.
After in the valve bag bag internal filler, the valve bag bag body is square, the overlapping portion of the two panels PE films
Divide at the middle separated time of the valve bag bag body side surface.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
