Abstract
The utility model discloses a kind of sodium sulfide packaging bag, comprise internal layer (1), outer (3) and interlayer (2), outer (3) are craft paper, interlayer (2) is the multiple film Polywoven Bag of polypropylene or polyethylene, described interlayer (2) and skin (3) through being hot pressed into composite bed, internal layer (1) for the internal layer (1) described in independent stratum be wafer, this packaging bag can effectively damp proof, moistureproof, break-resistance, lower than Steel Drum Packaging cost, be applicable to long-distance transport, and not easily leak.
Description
Technical field
The utility model relates to a kind of sodium sulfide packaging bag, comprises internal layer, skin and interlayer.
Background technology
Sodium sulfide Na2S, is commonly called as akali sulphide, and anhydrous sterling is isometric crystal system white crystals.Be corrosive, easy deliquescence; Water-soluble, solution alkaline; Acid decomposition produces hydrogen sulphide; Oxidizable in atmosphere.Industrial goods contain different crystal water (Na2SxH2O), general Containing Sulfur sodium about 60%, because being generally cream-yellow or baby pink containing a small amount of impurity.Product has bulk, sheet and graininess.Main as dehairing of hides agent, pulp cooking agent, the raw material of sulfur dye, dyestuff intermediate deoxidation compound, textile dyeing mordant, ore floatation agent, also can be used as sulphur removal agent and produces NaHS and sodium polysulfide raw material etc.
At present, China's sodium sulfide mostly adopts Steel Drum Packaging, and cost is high, and packing repeatedly use after can be aging, cause sodium sulfide to make moist leakages, contaminated environment, endangers the health of people.
Utility model content
The purpose of this utility model is to provide a kind of sodium sulfide packaging bag.
The technical solution adopted in the utility model is: a kind of sodium sulfide packaging bag, comprise internal layer, skin and interlayer, skin is craft paper, and interlayer is the multiple film Polywoven Bag of polypropylene or polyethylene, described interlayer and outer through being hot pressed into composite bed, internal layer for the internal layer described in independent stratum be wafer
As further improvement of the utility model, described composite bed is provided with opening part, and opening part is away from internal layer.
The beneficial effects of the utility model are: this packaging bag can effectively damp proof, moistureproof, break-resistance, lower than Steel Drum Packaging cost, are applicable to long-distance transport, and not easily leak.
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 opening part, and opening part is away from internal layer 1.
When opening the package, only needing to open from composite bed opening part, because internal layer 1 is wafer packaging, can directly process without the need to opening internal layer 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 sodium sulfide packaging bag, comprise internal layer (1), outer (3) and interlayer (2), outer (3) are craft paper, interlayer (2) is the multiple film Polywoven Bag of polypropylene or polyethylene, it is characterized in that: described interlayer (2) and outer (3) through being hot pressed into composite bed, internal layer (1) for the internal layer (1) described in independent stratum be wafer.
2. a kind of sodium sulfide packaging bag according to claim 1, is characterized in that described composite bed is provided with opening part, and opening part is away from internal layer (1).
