Specific embodiment
The following figure be described with reference to the drawings and specific embodiment the present invention will be further described.
A kind of high-barrier microchannel vacuum bag as shown in Figure 1 is to pass through hot pressing by first bag of face 1 and second bag of face 2
Made of, it is the viscous edge sealing being pressed at three side edges of vacuum bag, reveals a side opening, first bag of face 1 and second bag of face 2
It is fixedly connected by edge sealing, the top in first bag of face 1 and second bag of face 2 is fixed to be installed with opening 6, and the edge sealing includes a left side
Edge sealing 3, right edge sealing 4 and underseal side 5 are equipped with tooth mouth 8 on the left edge sealing 3 and (or) right edge sealing 4, can when opening 6 bonds
Vacuum bag is opened to remove hermetic unit by tooth mouth 8.
The schematic diagram of a layer structure in first bag of face 1 or second bag of face 2 as described in Figure 2, including sequentially connected gather inclined two
Vinyl chloride 71, nylon layer 72 and polyethylene layer 74 pass through the bonding connection of glue 73 between the nylon layer 72 and polyethylene layer 74.
When in use, article needs saved is put into vacuum bag from opening, is vacuumized using evacuator
Sealing.Efficiency is vacuumized in order to improve, the inside in first bag of face 1 and second bag of face 2 is equipped with embossing, and the embossing is set
In on polyethylene layer 74, embossing is conducive to form gas channels inside vacuum bag, and pumping effect can be improved.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure made based on the specification and figures of the utility model is applied directly or indirectly in other relevant technologies
Field is also included in the patent protection scope of the utility model.
