Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
A kind of high resistant oxygen packaging bag as shown in Figure 1, Figure 2 and Figure 3, including at least one layer of wrapper 1, at least one layer of waterproof
Layer 2 and at least one layer of antioxidation coating 3, each layer of wrapper 1 is a sealing structure, and the sealing structure includes bag body 4 and bag
Mouth 5, the sack 5 is in the bottom end of bag body 4, and sack 5 is funnel type, and unsealing pull line 6 is equipped at sack 5, is sealed off
Bracing wire 6 slides the material in bag body 4 for opening sack 4, and every layer of waterproof layer 2 is pasted onto the interior of one layer of wrapper 1
Surface, the waterproof layer 2 include PVDC (polyvinylidene chloride), and every layer of antioxidation coating 3 is pasted onto the interior of one layer of waterproof layer 2
Surface, the antioxidation coating 3 include PVOH water soluble film；PVOH water soluble film is a kind of polyhydroxylated polymer, in alcoholysis degree appropriate
There is down film forming, due to the effect of intermolecular hydrogen bonding, oxygen barrier is better than EVOH (ethylene-vinyl alcohol copolymer) and PVDC
(Vingon), but due in the water-soluble membrane molecule of PVOH with the presence of hydrophilic hydroxyl so that pure PVOH water soluble film film is in height
It is easy water suction under the conditions of humidity (relative humidity 45%-90%), the barrier property of oxygen is substantially reduced and is even disappeared, therefore
Waterproof layer 2 is set outside antioxidation coating, to guarantee the performance of antioxidation coating,
Wherein, when the wrapper 1 is one layer, one layer of wrapper 1 and waterproof layer 2, the formation of antioxidation coating 3 one are close
The flexible containers of envelope；
When the wrapper 1 is two layers or more, pass through waterproof layer, oxygen between one layer of wrapper and another layer of wrapper
Change layer to cohere to form composite construction, to constitute the flexible containers of the sealing.
In the above-mentioned technical solutions, the two sides of 4 bottom of bag body are equipped with the tear-off opening 9 for tearing.
In the above-mentioned technical solutions, sealing plate structure is equipped at the sack 5, the sealing plate structure includes seal base
7 are arranged in the one side of sack 5 with sealing upper plate 8, seal base 7, and sealing upper plate 7 is arranged in the another side of sack 5, seal base
One end is hinged between 7 and sealing upper plate 8, and for the other end by buckle or snap-fastener connection, seal base 7 and sealing upper plate 8 are openable
End between connection type it is varied, however it is not limited to buckle or snap-fastener connection such as are bolted good.Seal bottom
Opening state when plate 7, sealing upper plate 8 are flat, when material in packaging bag using when have more than needed, or need to shut down
When, seal base 7, sealing upper plate 8 are connected together by snap-fastener or buckle, so that sack 5 be made to be again sealed off, subtracted as far as possible
Moisture, oxygen or other materials in small air have an impact the substance in packaging bag, guarantee the performance indexes of material,
Raw material has been saved, production cost is reduced.
In the above-mentioned technical solutions, the wrapper 1 is in papery wrapper, plastics package layer or non-woven fabrics wrapper
It is one or more of.
In the above-mentioned technical solutions, the surface of the waterproof layer 2 is equipped with silver powder layer.Silver powder layer can make the packaging bag impermeable
Light reduces influence of the illumination to material in packaging bag.
In the above-mentioned technical solutions, it is bonded between the waterproof layer 2 and antioxidation coating 3 by primer.
In the above-mentioned technical solutions, the PVDC of the waterproof layer 2 is formed by being coated with PVDC lotion on substrate, PVDC cream
The coating weight of liquid is in 1.5-3.0g/ ㎡.Coating weight may reduce barrier property lower than above-mentioned recommendation, and coating weight is higher than above-mentioned
Recommendation but not necessarily can be improved barrier property.Can single side apply, two-sided can also apply, substrate can be used Biaxially oriented polypropylene it is thin
Film, biaxially oriented polyester film, aluminium foil, paper etc.；It selects depending on the application, a variety of different barrier films is made.
The characteristics of PVDC lotion can be coated in several ways, depend on substrate and appointed condition: it is not needing
Accurate measurement occasion, frequently with reverse print roll coating；In the case where needing more accurate coating weight, it should be coated with using air-blade type
Or wire rod coating, dip coated, it is not physically contacted with substrate in the former coating process, can be used for high speed, the latter is then easy to operate, but only
It is suitble to lower speed.
PVDC lotion can be used on paper, glassine paper, PP, PET, PE and nylon being coated with, and applying is including fast canteen
In the packaging of product, cheese, meat and medicine etc..
PVDC coating has outstanding barrier property, and very low oxygen, smell and moisture transmitance.PVDC coating also has
Good heat sealability, oil resistivity, solvent resistance, wearability, flexibility, glossiness and anti-flammability etc..
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
