Abstract
The utility model discloses a kind of cement package bags, comprise internal layer (1), outer (3) and interlayer (2), described internal layer (1) is wafer, outer (3) are craft paper, interlayer (2) is the multiple film Polywoven Bag of polypropylene or polyethylene, this packaging bag can effectively damp proof, moistureproof, break-resistance, is more suitable for long-distance transport, and not easily leaks than woven bag.
Description
Technical field
The utility model relates to a kind of cement package bags, comprises internal layer, skin and interlayer.
Background technology
Cement, powdery hydraulicity inorganic coagulation material.Add water after stirring and become slurry, can harden in atmosphere or better harden in water, and can the material such as sand, stone is cemented together securely, the cement concrete made with its cementing rubble, after sclerosis, not only intensity is higher, and can also resist the erosion of fresh water or brackish water.For a long time, it, as a kind of important Binder Materials, is widely used in the engineerings such as civil construction, water conservancy, national defence.
At present, China's cement mostly adopts woven bag to pack, and cost is high, and packing repeatedly can be aging after practicality, causes cement to make moist and solidify, contaminated environment.
Utility model content
The purpose of this utility model is to provide a kind of cement package bags without the need to sealing off.
The technical solution adopted in the utility model is: a kind of without sealing off cement package bags, comprise internal layer, skin and interlayer, described internal layer is wafer, skin is craft paper, interlayer is the multiple film Polywoven Bag of polypropylene or polyethylene, described interlayer and skin are through being hot pressed into composite bed, and internal layer is independent stratum.
As further improvement of the utility model, described composite bed is provided with tears mouth, tears mouth away from internal layer.
The beneficial effects of the utility model are: this packaging bag can effectively damp proof, moistureproof, break-resistance, are more suitable for long-distance transport than woven bag packaging, and not moisture-sensitive, solidify.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 internal layer, 2 interlayers, 3 is outer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model detailed description of the invention is elaborated.
As shown in Figure 1, the present embodiment comprises internal layer 1, skin 3 and interlayer 2, internal layer 1 is wafer, outer 3 is craft paper, interlayer 2 is the multiple film Polywoven Bags of polypropylene or polyethylene, and interlayer 2 and outer 3 is through being hot pressed into composite bed, and internal layer 1 is independent stratum, composite bed is provided with tears mouth, tears mouth away from internal layer 1.
When opening the package, only needing will to tear mouth from composite bed and open, because internal layer 1 is wafer packaging, can directly process without the need to opening internal layer 1 aborning.
The wafer moisture absorption, outer 3 craft papeies can moistureproof, anti-leak, and interlayer 2 also has the function of moistureproof anti-leak.
Below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Claims (2)
1. a nothing seals off cement package bags, comprise internal layer (1), outer (3) and interlayer (2), it is characterized in that: described internal layer (1) is wafer, outer (3) are craft paper, interlayer (2) is the multiple film Polywoven Bag of polypropylene or polyethylene, interlayer (2) and outer (3) are through being hot pressed into composite bed, and internal layer (1) is independent stratum.
2. according to claim 1 a kind of without sealing off cement package bags, it is characterized in that described composite bed is provided with and tear mouth, tear mouth away from internal layer (1).
