Abstract
The utility model discloses a kind of air-permeable dampproof packaging bag, including outer packaging layer, inner packing layer and the one-way exhaust passage being arranged between the outer packaging layer and the inner packing layer；The one-way exhaust passage and the one-way exhaust valve through connection for being located at the inner packing layer, the one-way exhaust passage is arranged to multiple, sack of the exhaust outlet of the one-way exhaust passage along the air-permeable dampproof packaging bag is circumferentially disposed, and the adjacent one-way exhaust passage insertion is set.With the air-permeable dampproof packaging bag of this structure design, caused waste gas in packaging bag can timely be discharged, and then avoid waste gas from causing material in bag to go mouldy after assembling by penetrating the one-way exhaust passage set with one-way exhaust valve.
Description
Technical field
It the utility model is related to packing technique field, more particularly to a kind of air-permeable dampproof packaging bag.
Background technology
It is used for the packaging bag for containing powder material under prior art, it is most using sealing and impermeable to prevent that material is excessive
The plastic bag of gas is held, and is packed in this way, in use, because gas can not be discharged in time in bag,
Thus under the effect of expanding with heat and contract with cold, the globule can be formed, material in bag is in turn resulted in and goes mouldy.
Utility model content
The purpose of this utility model is to provide a kind of air-permeable dampproof packaging bag that can effectively prevent that material goes mouldy in bag.
To use following technical scheme up to this purpose, the utility model：
A kind of air-permeable dampproof packaging bag, including outer packaging layer, inner packing layer and be arranged at the outer packaging layer with it is described
One-way exhaust passage between inner packing layer；The one-way exhaust passage passes through with being located at the one-way exhaust valve of the inner packing layer
Lead to and connect, the one-way exhaust passage is arranged to multiple, and the exhaust outlet of the one-way exhaust passage is along the air-permeable dampproof packaging bag
Sack it is circumferentially disposed, and the insertion of the adjacent one-way exhaust passage is set.
Wherein, multiple one-way exhaust passage parallel intervals are arranged at the both sides of the air-permeable dampproof packaging bag.
Wherein, the inlet end of multiple one-way exhaust passages penetrates successively is provided with gas sampling passage, the waste gas
Collection channel is set with the insertion of the multiple one-way exhaust valve.
Wherein, the partition wall between the adjacent one-way exhaust passage is by the outer packaging layer and the inner packing layer hot pressing one
It is body formed.
Wherein, the inner packing layer is arranged to water accepting layer.
The beneficial effects of the utility model：The utility model includes outer packaging layer, inner packing layer and is arranged at described outer
One-way exhaust passage between wrapper and the inner packing layer；The one-way exhaust passage is with being located at the inner packing layer
One-way exhaust valve through connection, the one-way exhaust passage are arranged to multiple, and the exhaust outlet of the one-way exhaust passage is saturating along this
The sack of gas moisture-proof packing bag is circumferentially disposed, and the adjacent one-way exhaust passage insertion is set.With the ventilative of this structure design
Moisture-proof packing bag, can by penetrating the one-way exhaust passage set with one-way exhaust valve, by caused waste gas in packaging bag and
When discharge, and then avoid waste gas assemble after cause material in bag to go mouldy.
Brief description of the drawings
Fig. 1 is a kind of structural representation of air-permeable dampproof packaging bag of the utility model.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
As shown in figure 1, a kind of air-permeable dampproof packaging bag in the present embodiment, including outer packaging layer 1, inner packing layer 2, Yi Jishe
The one-way exhaust passage 3 being placed between the outer packaging layer 1 and the inner packing layer 2；The one-way exhaust passage 3 is with being located at
The through connection of one-way exhaust valve 4 of the inner packing layer 2, the one-way exhaust passage 3 is arranged to multiple, and the one-way exhaust
Sack of the exhaust outlet of passage 3 along the air-permeable dampproof packaging bag is circumferentially disposed, and multiple parallel intervals of one-way exhaust passage 3 are set
The both sides of the air-permeable dampproof packaging bag are placed in, the inlet end of multiple one-way exhaust passages 3 penetrates successively is provided with waste gas receipts
Collect passage 5, the gas sampling passage 5 is set with the insertion of the multiple one-way exhaust valve 4, the adjacent one-way exhaust passage 3
Between partition wall be integrally formed by the outer packaging layer 1 and the hot pressing of inner packing layer 2, in order to play more preferable moisture-proof role,
The inner packing layer 2 is arranged to water accepting layer, and water accepting layer could be arranged to bilayer, the inside sandwiched drier.
, can be by penetrating the unidirectional row set with one-way exhaust valve using the air-permeable dampproof packaging bag of said structure design
Gas passage, caused waste gas in packaging bag is timely discharged, and then avoid waste gas from causing material in bag to go mouldy after assembling.
The present embodiment, can be close by the adjacent inner packing layer at sack when being sealed to the air-permeable dampproof packaging bag
It is bonded, on the premise of the exhaust outlet for only staying an one-way exhaust passage 3 again afterwards, outer packaging layer and inner packing layer is closely tied
Close.
Technical principle of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the limitation to scope of protection of the utility model can not be construed in any way.Based on explanation herein,
Those skilled in the art, which would not require any inventive effort, can associate other embodiments of the present utility model,
These modes are fallen within the scope of protection of the utility model.
