Description
Technical field
The utility model relates to a kind of packaging bag, particularly relates to the powder package bag that a kind of protection against the tide is vented again.
Background technology
Packaging bag is used to pack the thinner powder of particle diameter and modified powder, and due to modified powder good fluidity, and particle diameter is also little, easily spills from the pore of general vinyon packaging bag, so very easily causes the wasting of resources.Existing conventional heavy-duty bag, centre is provided with high-density polyethylene layer, but the packaging bag of this structure is when automatically packing, and is unfavorable for exhaust, can sets off an explosion, bring very large hidden danger to staff's personal safety.
Summary of the invention
In order to overcome the above problems, the utility model proposes a kind of structure design simple, reasonable, cost is low, use reliable, aeration is good, can prevent the moisture in air from entering in bag, can prevent again the powder in packaging bag from leaking, blast can also be prevented, ensure that the powder package bag that the protection against the tide of packaging quality is vented again.
The utility model is achieved through the following technical solutions:
The powder package bag that above-mentioned protection against the tide is vented again, is made up of internal layer, middle level and outer bound; Described internal layer adopts the craft paper with permeability to air; Described middle level adopts high density polyethylene (HDPE); Described skin also adopts the craft paper with permeability to air; Described internal layer, middle level and outer field two ends are sealed connected together; Described middle level and the outer tiny internal plug seat being inlaid with even compact; Described packaging bag is at one end also provided with valve port.
The powder package bag that described protection against the tide is vented again, wherein: the tiny internal plug seat of described even compact is specifically inserted from described middle level and plugged formation to described skin.
The powder package bag that described protection against the tide is vented again, wherein: described inside and outside layer all adopts yellow clupak kraft paper.
The powder package bag that described protection against the tide is vented again, wherein: what described middle level adopted is density polyethylene film with high layer.
The powder package bag that described protection against the tide is vented again, wherein: described internal layer, middle level and outer field two ends are bonded together by adhesive sealing.
Beneficial effect:
The powder package bag structure design that the utility model protection against the tide is vented again is simple, rationally, easy to use, reliable, cost is low, and wherein, valve bag self-closed without the need to seam bag, and without dust from flying time filling, belongs to enviroment protective packing bag; Inside and outside layer all adopts the craft paper with certain air permeability, has certain permeability to air and atresia, ensure that powder is not discharged, but air can be discharged; Meanwhile, the design of internal plug seat, both can be vented, and prevented blast, can prevent again the moisture in air from entering in powder, cause reunion, thus ensure that the quality of powder; For the powder of modification, good fluidity, this packaging bag makes powder leak, and ensure that the quality of packaging.
Accompanying drawing explanation
Fig. 1 is the structural representation of the powder package bag that the utility model protection against the tide is vented again.
Fig. 2 is the section-drawing of the powder package bag that the utility model protection against the tide is vented again.
Detailed description of the invention
As shown in Figure 1, 2, the powder package bag that the utility model protection against the tide is vented again, it is made up of internal layer 1, middle level 2 and outer 3 bondings.
This internal layer 1 adopts yellow clupak kraft paper and has certain permeability to air, and it is the yellow clupak kraft paper of 90G that this internal layer 1 specifically adopts; What this middle level 2 adopted is density polyethylene film with high layer, and what it specifically adopted is 1.5 density polyethylene film with high layers; This skin 3 also adopts yellow clupak kraft paper and has certain permeability to air, specifically adopts the yellow clupak kraft paper of 90G; Wherein, this internal layer 1, middle level 2 and outer 3 two ends bonded together by adhesive; This packaging bag is at one end also provided with valve port 4.Meanwhile, be evenly inlaid with fine and close tiny internal plug seat (not shown) between this middle level 2 and outer 3, the yellow clupak kraft paper that this internal plug seat specifically inserts outer layers 3 from the film layer in middle level 2 plugs and forms.
Use principle of the present utility model:
After automatic weighing and packing machine starts, the discharging opening nozzle of wrapping machine is inserted the valve port place of valve port kraft paper bag, from top valve port charging, filling material back pkt. becomes cube, self-closed is without the need to seam bag, in packaging process, air enters valve bag together with powder, because inner layer kraft has certain permeability to air and atresia, ensure that powder is not discharged, but air can be discharged, air pressure in bag makes internal plug seat open exhaust, prevent blast, when packaging completes, without air pressure in bag, internal plug seat closes, prevent the moisture in air from entering in powder, cause reunion, meanwhile, without dust from flying time filling, belong to enviroment protective packing bag, after having packed, in warehouse storage, especially for the powder of modification, good fluidity, this packaging bag makes powder leak, and ensure that the quality of packaging.
The utility model structure design is simple, rationally, cost is low, and use reliable, aeration is good, also can prevent the moisture in air from entering in bag, can also prevent blast, can prevent the powder in packaging bag from leaking, ensure that the quality of packaging.
