Technical field
The utility model is related to package packing machine field, especially a kind of valve bag.
Background technology
With the continuous development of present material science, novel material emerges in an endless stream, and material property is also constantly changing,
Want preferably to preserve, transport, sell, the packing instructions of its product will also be improved therewith.Valve bag is as a kind of main
Packing appliance, carry important role in tasks such as the storages, transport, sale of material.As a kind of storage apparatus,
Require valve bag with certain to material protection effect, for the characteristic of a variety of materials, valve bag must have corresponding anti-
Each attribute such as light, moisture-proof, antistatic, to ensure that material never degenerates discoloration within certain time limit；It, will be straight as a kind of outer packing
It connects and is contacted with user, give user most intuitive impression, this requires valve bag is durable, be conveniently operated, concise beauty
It sees.
Current valve bag can be divided by material：PP valve bags, PE valve bags, paper-plastic stick valve bag, brown paper valve port
Bag and multiwall kraft valve bag.Paper-plastic stick valve bag is using Polywoven Bag as base material, is made after the tape casting is compound.
In high-pressure filling, existing valve bag is all made of the gas permeability that valve bag is thereby reduced using the material thickeied；And paper
Combination valve pocket is moulded, by existing technology, is made of the longitude and latitude of the paper by outer layer and internal layer institute plastic woven material, it is such
Valve bag, which easily makes moist, causes valve bag quality to decline, cracky, causes to bear the reduction of material ability.
And a kind of presently disclosed valve bag (CN20162090260.0) containing internal lining paper, solve valve bag substantially
The problem of gas permeability and leakproofness cannot get both, valve bag makes moist cracky, but its have anti-impact force it is indifferent, easily by oxygen
The property changed acid burn into liner paper layer fallibility position, valve port seal the shortcomings of bad, and the PE of outer packing after material has been filled
Coating layer color and luster is dim, influences beauty.
Invention content
To overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of composite valve pocket, the valve bag material
Expect that economic and environment-friendly, sealing convenience, good permeability, corrosion-resistant, moisture-proof, shock resistance and color and luster light are gorgeous.
The technical scheme in the invention for solving the technical problem is：
A kind of composite valve pocket, including valve bag bag body and valve port, the valve bag bag body ecto-entad includes successively
Composite film and liner paper layer；The composite film is OPP color printings film layer, ecto-entad combines successively for curtain coating film layer and braiding layer
It forms；The curtain coating film layer is formed by PP materials and PE Material claddings；The valve port has certain length, is placed in the valve port
Bag bag body side, one end protrusion bag body of the valve port, the other end introduces the internal portion of bag, and the valve port is filled in material and completed
Bag body is folded into backward and completes closing.
Preferably, the composite bed is connected conjunction with liner paper layer, it is whole staggeredly in seam winding connection forms bag body；Its purpose
It is, overall processing can reduce production process, reduce cost, improve labor efficiency.
It is further preferred that the curtain coating film layer is covered in the braiding layer outer surface using ultrasonic welding technique；Its
Purpose is that manufacture craft is ripe, high yield rate.
Preferably, the OPP color printings film layer is applied to the curtain coating film layer outer surface using coating technique；Its purpose exists
In covering is uniformly beautiful.
It is further preferred that the composite film uses cross viscosity item phase joint with liner paper layer；It is intended that through
Ji is practical, easy to operate.
It is further preferred that the viscosity item intersects into "+" type structure；It is intended that preferably fix the liner
Relative position of the paper layer on the composite film prevents the transverse direction and longitudinal direction of the liner paper layer from misplacing.
Preferably, the valve port is formed by braiding layer material therefor cigarette, with the valve bag bag body cohesive material glue
Knot.
Preferably, the valve port is placed in the internal portion's partial-length of the bag not less than 100m；It is intended that treat that material is filled out
Preferably valve port can be squeezed to form sealing after the completion of filling.
Compared with prior art, the utility model advantageous effect is：The composite film is composed for various material,
Ecto-entad includes OPP color printings film layer, curtain coating coating layer and braiding layer, collection and each material advantage successively, improves valve
The gas permeability of pocket bag body, corrosion resistance, anti-impact force and appearance luster light are gorgeous；The change of the viscosity item and valve mouth structure, makes
The valve bag is easy to make, sealing is more tight reliable.
