Abstract
The utility model relates to oxygen absorbent packaging material which belongs to the technical field of packaging material. Pe coated paper with holes and at least two layers of films which are coated on the surface of the pe coated paper and are provided with holes form a whole composite layer, and the holes of the film and the holes of the pe coated paper are staggered. Because the oxygen absorbent packaging material is the whole composite layer, so the holes on the pe coated paper and the holes on at least two layers of films on the surface of the pe coated paper are staggered and unchanged, and the oxygen absorbent packaging material can prevent powder from being leaked while ensuring the permeability compared with traditional oxygen absorbent packaging material.
Description
Technical field
The utility model relates to a kind of packing that are used for oxygen absorbent, belongs to field of packaging material.
Background technology
The packing (generally being composite bed) that are used to hold oxygen absorbent require not only ventilative but also can stop that powder sees through to leak outside, and prevent contaminated food products.
Existing oxygen absorbent packing generally are to make clear opening to satisfy ventilative requirement on material.But the possibility that this clear opening exists powder to leak outside undoubtedly.Such as, national 08 year new industry standard has only been stipulated the index of aperture≤100 μ m to packaging material in the clear opening, yet the oxygen absorbent (as thin iron powder and active carbon) of existing at present material footpath≤50 μ m, when the packing of 50 μ m≤apertures≤100 μ m are used to hold the powder of material footpath≤50 μ m, will cause powder to leak outside.If adopt simply and make the more method of small-bore clear opening, need more high-precision punch device undoubtedly, this just not only increases the manufacturing cost of punch device,
In addition, the interlayer of existing oxygen absorbent packing is general to adopt simple adhesion process, because with an organic solvent (ethyl acetate, acetone) dilutes glue, and easily at the interlayer residual organic solvent of packing, not only contaminated environment but also be detrimental to health.
Retrieval is found, the Chinese patent of application number 0022193.6 discloses a kind of Deoxidizing agent bag, this Deoxidizing agent bag is made of two-layer gapped each other compound internal layer and compound skin, Kong Jun on compound internal layer or the compound skin is a clear opening, though stagger each other in the position, hole on two-layer, but when two composite beds were movable toward each other, the position, part hole on two-layer might be just in time mutually to last, and this just still can cause deoxidation reagent to leak outside.
The utility model content
Primary technical matters to be solved in the utility model is to propose a kind of packing that prevent that effectively the oxygen absorbent powder from leaking outside.
The utility model for the technical scheme that solves above-mentioned primary technical matters proposition is: a kind of oxygen absorbent packing, constituting whole composite bed by leaching membrane paper with holes and the two membranes at least with holes that is laminated with on the leaching membrane paper paper, staggers each other in the hole of described film and the hole of leaching membrane paper.
As mentioned above, oxygen absorbent packing of the present utility model are whole composite beds, thus this composite bed to be positioned at the hole of leaching membrane paper and to be positioned at that hole on the two membranes at least of leaching membrane paper paper staggers each other be to determine unmodified.During use, hole and leaching membrane paper that gas can see through on the two membranes at least are (well-known, the fiber structure of paper has permeability to air), and powder can't see through the hole of staggering each other on the two membranes at least and leaching membrane paper (fiber structure of paper tortuous circuitous and latus rectum is minimum).Like this, compare existing oxygen absorbent packing, oxygen absorbent packing of the present utility model just can prevent effectively that powder from leaking outside when guaranteeing permeability to air.
Less important technical matters to be solved in the utility model is on the basis that solves primary technical matters, to propose the good oxygen absorbent packing of a kind of feature of environmental protection.
The utility model for solving above-mentioned less important technical matters to improvement of the technical scheme is: described leaching membrane paper and described film hot pressing each other are combined into whole composite bed.Like this, because whole composite bed all is that hot pressing is composited, therefore cuts off the non-volatility organic matter, thereby make powder packaging material of the present utility model have more the feature of environmental protection.
Further improvement in the technical proposal is: described film is first tunic and second tunic that is overlying on first tunic that is overlying on the leaching membrane paper paper, and described first tunic is the low melting point thermoplastic resin film, and described second tunic is a polyester film.
Further improving again of technique scheme is: be shaped on through hole on the described leaching membrane paper.Like this, can promote the permeability to air of leaching membrane paper and whole composite bed.
The perfect of technique scheme is: described leaching membrane paper is made of ply of paper and the polyethylene film layer that is overlying on ply of paper one side, and described leaching membrane paper paper is the another side that ply of paper does not cover polyethylene film layer.
Description of drawings
Be described further of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment one oxygen absorbent packing.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the birds-eye view of Fig. 1.
The specific embodiment
Embodiment one
The oxygen absorbent packing of present embodiment as shown in Figure 1, (leaching membrane paper generally is the integral body that is made of ply of paper 1-1 and the polyethylene film layer 1-2 that is overlying on ply of paper 1-1 one side by leaching membrane paper, this is a known technology) and first, second two membranes 2,3 with holes that is laminated with on leaching membrane paper paper (described paper refers to that promptly ply of paper 1-1 does not cover the another side of polyethylene film layer 1-2, and this also is a known technology) constitute whole composite bed.First tunic 2 is low melting point thermoplastic resin films, and second tunic 3 is polyester films.Be equipped with first clear opening 4 on the leaching membrane paper, also be equipped with second clear opening 5 that is in alignment with each other and the 3rd clear opening 6, the first clear openings 4 and second clear opening 5 on first, second tunic 2,3 respectively and stagger mutually.
The oxygen absorbent packing integral composite membrane of present embodiment is that hot pressing is composited entirely, promptly leaching membrane paper and first, second tunic 2,3 each other hot pressing be combined into whole composite bed, therefore environmental protection more.
Obviously, the foregoing description variation that can have is: 1) second clear opening 5 and the 3rd clear opening 6 on first, second tunic 2,3 also can stagger each other; 2) except first, second tunic 2,3, the 3rd layer, the 4th layer or more multi-layered film can also be arranged; Or the like.
The foregoing description that is not limited to of the present utility model, all employings are equal to replaces the technical scheme that forms, and all drops on the protection domain of the utility model requirement.
