Abstract
The utility model discloses a special paper packaging bag for light ultrafine powder, which comprises an inner layer, an outer layer and an interlayer. The inner layer, the outer layer and the interlayer are all made from stretchable paper, tops and bottoms of the inner layer, the outer layer and the interlayer are all connected mutually, a valve capable of being communicated with the external is connected to the top of the inner layer, micropores are distributed on the interlayer, and a polyethylene coated layer of the thickness smaller than 2micrometers is arranged on the surface of the interlayer. The special paper packaging bag for light ultrafine powder is attractive, easy to package, large in package capacity and is breathable and damp-proof.
Description
Technical field
The utility model relates to a kind of coated paper envelope, especially relates to powder body material specialized package paper bags such as a kind of lightweight superfine silicon dioxide, alundum (Al, titanium dioxide, zinc oxide, ultralight glass microsphere, carbon black.
Background technology
The lightweight superfine powdery material is widely used in fields such as rubber, plastics, coating, printing ink, photoelectricity, illumination as a kind of high performance material.This class material has characteristics such as particle is little, specific surface area is big, active height, usually its primary partical footpath is less than 100 nanometers, the apparent density of powder is between the 30-60 kilograms per cubic meter, bulk density also has only the 90-200 kilograms per cubic meter, as aerosil, gaseous oxidation aluminium, gas phase titanium dioxide, ultralight glass microsphere, ultralight carbon black etc.Because powder granule is little, specific surface area is big, makes that its hygroscopic character is strong, in storage, transportation, is easy to the moisture absorption and is agglomerated into piece.Existing be used for this type of powder package bag simple in structure, anti-soak properties are poor, if deal with improperly, are easy to cause the lightweight superfine powder caking that makes moist, influence follow-up dispersion of lightweight superfine powder and use, and then make the resulting product degradation; In addition, the packing material that is used to pack this type of powder mostly is hot melt closed type material, and along with the prolongation in storage time, the sealing position is aging, cause seal defect easily.
Summary of the invention
The technical issues that need to address of the present utility model are to provide a kind of lightweight superfine powder coated paper envelope, this coated paper envelope packing attractive in appearance, easy, not only ventilative, but also protection against the tide and bale capacity big.
The technical scheme that solves the problems of the technologies described above is as follows:
A kind of lightweight superfine powder coated paper envelope, comprise internal layer, skin and the intermediate course made by stretchable paper, internal layer, skin and intermediate course interconnect at its top, bottom position, the tip position of internal layer be connected with can with the valve port of exterior, be distributed with micropore on the intermediate course, the surface of intermediate course has leaching membrane layer, and the thickness of this leaching membrane layer is less than 2 microns.
The technical scheme of the further refinement of aforementioned techniques scheme can be:
Be provided with paper web on described valve port, paper web and described internal layer are bonding.
Described internal layer, skin and intermediate course at its top and bottom position bonding mutually, space, position between its top and bottom.Also can be provided with breather hole on described internal layer, the skin, further promote permeability.
Described micropore is interspersed on described intermediate course.More preferably, described finely porous aperture is 0.2 millimeter to 1 millimeter, and the spacing between the micropore is 5 millimeters to 20 millimeters.Adjacent four described finely porous lines can assume diamond in shape.The acute angle of described rhombus is that 60 degree are to 80 degree.
In sum, the utility model is compared with existing packing technique and is had following advantage:
1, is formed by stacking by multiwall kraft, has higher intensity.Skin can be white stretchable paper and opens, and is convenient to printing, and is specious.Intermediate course is hydrophobic composite bed, and the leaching membrane layer that drenches the film processing through the polyethylene fusion has good moistureproof and waterproof effect, and has further promoted the stretching and the peel strength of paper bag.
2, described micropore is interspersed on described intermediate course, and the micropore regular distribution that can assume diamond in shape is convenient to pack exhaust, improves package speed.
3, coated paper envelope has valve port, and valve port is provided with paper web, and powder enters packaging bag from paper web through valve port, and valve port has non-return design, can prevent flying upward of lightweight superfine powder in the packaging process effectively and causes dust pollution.
4, inside and outside layer and intermediate course craft paper are non-bonding, and the marquis provides more gas passage during for packing, and are convenient to recycle.During recovery sack is torn and craft paper and treatment paper can be separated, be convenient to recycle.
5, the size of packaging bag is changeable according to demand, can reach 1100 * 750 * 180mm in case of necessity.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the surface structure scheme drawing of lightweight superfine powder coated paper envelope described in the utility model;
Fig. 2 is the A-A cutaway view Amplified image of embodiment shown in Fig. 1;

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
Shown in Fig. 1-2, the described lightweight superfine powder of present embodiment coated paper envelope comprises internal layer 1, skin 2 and intermediate course 3, and every layer is all adopted clupak kraft paper, its ectomesoderm 2 is white stretchable papers, is convenient to printing, and is specious.Internal layer 1 and intermediate course 3 are yellow stretchable papers, and the surface of intermediate course 3 has leaching membrane layer, and the thickness of this leaching membrane layer is less than 2 microns, and described leaching membrane layer drenches film through the polyethylene fusion to be handled, its store and transportation in have good moistureproof and waterproof effect.Internal layer 1 and outer 2 requirements according to package speed also can be provided with breather hole, further promote permeability.
Described lightweight superfine powder package top, each layer of bottom position are bonding mutually, each layer between its top and bottom the position apart from one another by; The tip position of internal layer 1 be connected with can with the valve port 4 of exterior, promptly valve port is provided with paper web 5, paper web 5 is adhered to the internal layer 1 on bag top, paper web can prevent flying upward of lightweight superfine powder in the packaging process effectively and cause dust pollution.
Also be provided with the micropore 6 that is interspersed on the intermediate course 3, described micropore size a size is between 0.2～1mm, and adjacent holes is 5 millimeters to 20 millimeters apart from b; Adjacent four described finely porous lines can assume diamond in shape, and the acute angle ∠ E of described rhombus is that 60 degree are to 80 degree, (as Fig. 3 and Fig. 4).But the design of described microcellular structure and each layer of bag body isolation structure lift gas mutually flow, and improve package speed, prevent the powder can generation packaging bag explosion phenomenon in the overshoot of bleeding.According to actual needs, the size of packaging bag described in the utility model is changeable, can reach 1100 * 750 * 180mm in case of necessity.
