Abstract
The utility model discloses a leak protection valve port and contain wrapping bag of this valve port. The utility model discloses a valve port of preparation new materials, the material of adorn in the protection bag, its simple structure improves with low costsly, and it is effectual to seal the leak protection. Have a dual leak protection insurance in that the valve port is inside, glass paper below the 40gm2 or PE can play and prevent that the material from getting into the effect of valve port, scribble the valve port of full hot melt adhesive and can avoid totally from valve port leakage material to the hot melt adhesive of scribbling is higher than normal atmospheric temperature, can not melt because weather is hot, only needs simple heating to plug up after the filling material finishes, and the problem that customer material leak was stopped to the root is followed in convenient easy operation.
Description
Technical field
The present invention relates to environmental protection type packing technology, and in particular to a kind of leakproof valve port and the packaging bag containing the valve port.
Background technology
Valve bag, is commonly called as being sticking bag, is current international popular packaging bag, feeds from top or bottom valve port, using special
Filling apparatus, dress up cube after filling material, heap bag is neat, attractive in appearance, belongs to Environmental protection bag.It is edible that valve bag is mainly used in packaging
The powderies such as powder, chemical powder, chemical fertilizer, synthetic material, explosive, grain, salt, mineral matter or granular solid material and flexible thing
Product.It is particularly suitable for export enterprise to use, the packaging class of product can be improved.
Generally people when being packed to material using valve bag, the mobility, volatility due to material, common valve
Although pocket has largely avoided the leakage of material, can not meet for the high client of comparison is required
Its demand, the valve bag with interior PE films is again prohibitively expensive relative to the material for leaking out, and seeks a kind of not only economical and practical but also energy
The valve bag of enough perfection leakproofs becomes current problem demanding prompt solution.
The content of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of leakproof valve port and the packaging bag containing the valve port.
The technical scheme is that：A kind of leakproof valve port, described valve port be by with PUR valve port paper roll into
Tubular and cutting make, the PUR be located at shaping paper web inner side.
Further improvement of the present invention includes：
The valve port set has been embedded in 40g/m2In following glassine paper or barrel-like structure obtained in PE, and one end of valve port is prolonged
Extend outside the barrel-like structure, the other end is located in barrel-like structure.
PUR on the valve port paper along the valve port center line coating.
Half of the coating width of PUR not less than valve port paper width on the valve port paper.
Joint close direction and the 40g/m of the valve port paper2Following glassine paper or the joint close of PE is in opposite direction.
Another object of the present invention is to provide a kind of valve-port packaging bag, above-mentioned leakproof valve port is it comprises.
The present invention further additionally provides a kind of preparation method of valve-port packaging bag, specifically at valve port Zhi Shangyanqi centers
Then line direction applying hot melt adhesives, coating width is coiled into disk-like structure not less than 1/2nd of valve port paper；To with heat
The valve port paper of melten gel carries out cutting drum；By valve port outside cladding tubular 40g/m2Following glassine paper or PE, make the one of valve port
End is extended to outside the barrel-like structure, and the other end is located in barrel-like structure, and then valve port is bonded on kraft paper bag, completes ox
The bonding of mulberry paper bag.
The valve port that the present invention passes through making new material, the material filled in protective bag, its simple structure, improving cost
Low, sealing and anti-leakage effect is good.There is double leak-proof to insure inside valve port, glassine paper (40g/m2Following paper)/PE can play anti-
Only material enters the effect of valve port, and filling the valve port of PUR can completely avoid the leaked substance from valve port, and applied
PUR is higher than normal temperature, can't be melted because of heat, is sealed by simple heating is only needed to after filling material is finished
Extremely, it is convenient easy to operate, the problem of client's material from leakage is prevented from root.

Fig. 3 is the structural representation of valve bag of the present invention.
In figure：1st, valve port paper, 2, PUR, 3, kraft paper bag, 4, valve port paper disc, 5, glassine paper, 6, bonding glue.
Specific embodiment
The present invention is elaborated below in conjunction with the accompanying drawings.
As shown in Figures 2 and 3, a kind of leakproof valve port of the invention, described valve port is by the valve port paper roll with PUR
Into tubular and cutting make, the PUR be located at shaping paper web inner side.The valve port set has been embedded in tubbiness obtained in glassine paper
In structure, and one end of valve port is extended to outside the barrel-like structure, and the other end is located in barrel-like structure.
PUR on the valve port paper along the valve port center line coating.The coating of PUR on the valve port paper
Half of the width not less than valve port paper width.
As shown in Fig. 2 the joint close of valve port paper of the present invention is towards, valve port system in opposite direction with the joint close of the glassine paper
Finish rear joint close down, with joint close upward 5, glassine paper be bonded together, glassine paper (40g/m2Following paper)/PE fill
After material terminates, a counnter attack material can be played a part of before seam to the material in bag, without material in valve port, the effect of seam is
Can more preferably, closed effect is also more preferable.
Another object of the present invention is to provide a kind of valve-port packaging bag, above-mentioned leakproof valve port is it comprises.
The present invention further additionally provides a kind of preparation method of valve-port packaging bag, specifically at valve port Zhi Shangyanqi centers
Then line direction applying hot melt adhesives, coating width is coiled into disk-like structure not less than 1/2nd of valve port paper；To with heat
The valve port paper of melten gel carries out cutting drum；By valve port outside cladding tubular glassine paper (40g/m2Following paper)/PE, make valve port
One end is extended to outside the barrel-like structure, and the other end is located in barrel-like structure, and then valve port is bonded on kraft paper bag, is completed
The bonding of kraft paper bag.
The valve port that the present invention passes through making new material, the material filled in protective bag, its simple structure, improving cost
