Description of the drawings
Fig. 1 shows the structural representation of the packaging bag of prevention powder reuniting according to an exemplary embodiment of the present invention.
Specific embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine by any way.
Any feature disclosed in this specification, unless specifically stated otherwise, can be equivalent or with similar purpose by other
Alternative features are replaced.I.e., unless specifically stated otherwise, each feature is an example in a series of equivalent or similar characteristics
.
First the structure of the packaging bag of present invention prevention powder reuniting is described in detail below.
Fig. 1 shows the structural representation of the packaging bag of prevention powder reuniting according to an exemplary embodiment of the present invention.Such as
Shown in Fig. 1, exemplary embodiment of the invention, the packaging bag of the prevention powder reuniting is by the internal layer packaging for packing powder body
Bag 2 and the outer packaging bag 1 that is sleeved on outside internal layer packaging bag 2 are constituted, the top of the top of internal layer packaging bag 2 than outer packaging bag 1
The top and outer packaging bag 1 for holding low and internal layer packaging bag 2 is compounded to form fixed composite log 3, and 1 top of outer packaging bag is also wrapped
The heat-sealing section 4 formed after powder body loads is included, wherein, internal layer packaging bag 2 is made up of ventilative water absorbing material, outer packaging bag 1
It is made up of plastic sheeting or sheet material.
Specifically, internal layer packaging bag 2 is the major part for accommodating and containing powder body, its top fix and with outer packaging bag
1 fixes the fixed composite log 3 of formation, and its bottom is free end and is located in outer packaging bag 1.Preferably, the top of internal layer packaging bag 2
End 1～20cm lower than the top of outer packaging bag 1, in order to the sealing of follow-up entire package bag；2 top 1 of internal layer packaging bag～
The width section of 30cm is compounded to form fixed composite log 3 with outer packaging bag 1, with ensure internal layer packaging bag 2 and outer packaging bag 1 it
Between connective stability and guarantee that the anti-agglomeration effect of packaging bag can be realized.
It is highly preferred that the ventilative water absorbing material of internal layer packaging bag 2 is by polyurethane, polyamide, cellulose and its is similar to
The adhesive-bonded fabric of at least one composition in thing, paper, yarn fabric or its analog.Wherein, do interior using ventilative water absorbing material
In the absorbable bag of layer packaging bag, the moisture of air, keeps the drying of air in bag, and can play dry work to powder body in bag
With so as to play a part of pre- anti-agglomeration.
Outer packaging bag 1 is to coat internal layer packaging bag 2 and powder body and completely cut off moisture and retain the main portion of air in bag
Point.The top of outer packaging bag 1 does not overlap with the top of internal layer packaging bag 2 and higher than the top of internal layer packaging bag 2, which is higher
Part can carry out follow-up heat-sealing encapsulation process and realize the sealing to powder body.Preferably, seal section width be 1～
10cm。
It is highly preferred that the plastic sheeting or sheet material of outer packaging bag 1 be high density polyethylene (HDPE), polyvinylidene chloride,
At least one in polyethylene terephthalate, polypropylene and the like.Further, the plastics of outer packaging bag 1
Thin film or sheet material outer surface can also include the coat or metal foil layer of silicon dioxide, aluminum or aluminium oxide.It is thin using plastics
Film or sheet material as outer packaging bag material primarily to the outside for completely cutting off extraneous air and avoiding moisture unstable
Air causes the reunion of powder body in bag into packaging bag.
The structure of above-mentioned packaging bag is basic structure, and the size of packaging bag specifically can be adjusted according to demand.In fact,
When actually carrying out the packaging of powder product, in addition it is also necessary to more effectively could realize preventing powder reuniting with reference to specific operational approach
Purpose and effect.
Next the method for present invention prevention powder reuniting is described further, specifically, the method is using above-mentioned
The packaging bag of prevention powder reuniting carries out the packaging of powder body.
Specifically may comprise steps of：Powder body is loaded in the internal layer packaging bag 2 in the packaging bag of prevention powder reuniting
And in making packaging bag, retain the air capacity under naturalness, 1 top end opening of outer layer packaging bag is sealed, the packaging after sealing
Bag seals not damaged under pile artesian condition.Subsequently, packaging bag of the gained equipped with powder body can be carried out the step of pile placement
Suddenly, such as 1 ton/pallet, can overlap 1～3 pallet of pile.
Wherein, the step of retaining the air capacity under naturalness after loading powder body is very necessary and crucial, in sealing
After packaging bag, the air being retained in packaging bag can make to have in packaging bag certain pressure and can be pressurized in packaging bag
When alleviate and be pressed onto pressure on powder body, namely these air can be prevented effectively from packaging bag equivalent to a mattress is formed
The pressure of square goods is directly pressed onto on the powder body in packaging bag and makes the pressurized reunion of powder body, and effectively alleviation powder body is under stress condition
Reunion.Meanwhile, the control of air capacity is also critically important, and air capacity may excessively make powder body make moist substantially and affect packaging bag
Load performance, air capacity are crossed and are not reached the effect for effectively preventing reuniting at least, retain the air capacity under naturalness.
It is proven, in the present invention, prevents the packaging bag of powder reuniting and effective anti-agglomeration time of method reach
6～12 months.
It should be understood that the above-mentioned embodiment and following examples of present invention detailed description are merely to illustrate the present invention rather than limit
The scope of the present invention processed, some nonessential improvement and tune that those skilled in the art's the above of the invention is made
