Fig. 1 is the utility model relates to a high resistant separates degradable wrapping bag orthographic view section-map, fig. 2 is the utility model relates to a high resistant separates degradable wrapping bag bleeder valve orthographic view section-map, fig. 3 is the utility model relates to a high resistant separates degradable wrapping bag air cavity overlooking the section-map, fig. 4 is the utility model relates to a high resistant separates degradable wrapping bag complex film structure chart, as shown in the figure, a high resistant separates degradable wrapping bag, including first bag body 1 and second bag body 2, the second bag body 2 outsides are arranged in to first bag body 1. The top of the first bag body 1 is symmetrically provided with an easy-to-tear opening 3, and a sealing strip 6 is arranged below the easy-to-tear opening 3. The edge of the first bag body 1 is provided with a U-shaped placing cavity 5 surrounding the outer side of the second bag body 2, and the inner side of the upper part of the placing cavity 5 of the first bag body 1 is provided with an air exhaust valve 4. The inside of air cavity 7 of bleeder valve 4 is equipped with shifting chute 8, evenly is equipped with a plurality of fixed slots 11 on the solid fixed ring 10 of shifting chute 8 bottom, and fixed slot 11 one side articulates there is the flexure strip 12 rather than matching. The interior of the movable groove 8 is connected with an air cavity cover 9, a first air valve 13 at the bottom of the air cavity 7 is communicated with the interior of the first bag body 1, and a second air valve 14 on the air cavity cover 9 is communicated with the air cavity 7. The second bag body 2 is used for vacuum packaging of articles, and the first bag body 1 protects the second bag body 2 when in an unopened state. After the first bag body 1 and the second bag body 2 are both unsealed, the first bag body 1 vacuumizes the second bag body 2 or other articles contained therein through the air extraction valve 4. The first bag body 1 can be repeatedly used, so that the repeated utilization rate is improved, and the environmental pollution is reduced. The air cavity cover 9 can move up and down along the moving groove 8, and when the air cavity cover 9 is pressed downwards, the air cavity cover 9 is gradually contacted with the elastic piece 12 until the elastic piece 12 is connected with the fixed groove 11. At this time, the air inside the air chamber 7 is discharged through the second air valve 14, and the inside of the air chamber 7 is vacuumed. After the hand is released, the elastic sheet 12 recovers deformation to jack up the air cavity cover 9 upwards, and at the moment, the air in the first bag body 1 enters the air cavity 7 through the first air valve 13. The air chamber cover 9 is pressed again to completely discharge the air introduced from the first bag body 1 into the air chamber 7. The air chamber cover 9 is repeatedly pressed to complete the vacuum-pumping treatment of the inside of the first bag body 1 sealed by the sealing strip 6.

The composite film structure of the first bag body 1 and the second bag body 2 is the same, and the composite film is sequentially a PLA layer 15, a PVA layer 16 and a PBAT layer 17 from outside to inside. The PLA layer 15 has good tensile strength and ductility, oxygen permeability and carbon dioxide permeability, and serves as an outer layer to isolate odors. The PVA layer 16 is used as an intermediate bonding layer, and has excellent barrier property, good toughness and high tensile strength. The PBAT layer 17 is a heat-seal layer, and has good ductility, elongation at break, heat resistance, and impact resistance, and excellent processability. The three-layer co-extrusion becomes the complex film, abandons the back when first bag body 1 or second bag body 2, but degrades into carbon dioxide and water in the short time, and green is pollution-free.

The placing cavity 5 is positioned below the sealing strip 6, the opening of the placing cavity 5 is consistent with the opening direction of the first bag body 1, and a drying agent is placed in the placing cavity 5. The arrangement cavity 5 is provided with a plurality of through holes on the inner side of the first bag body 1, and the through holes are matched with the drying agent, so that the drying environment after the first bag body 1 is vacuumized is further ensured, and the vacuumized articles can be stored for a long time.

An annular limiting plate 18 is arranged at the top of the air cavity 7, an annular limiting block 19 matched with the limiting plate 18 is arranged at the lower edge of the air cavity cover 9, and a sealing ring is sleeved on the limiting block 19. When the air cavity cover 9 moves upwards to the top of the air cavity 7 along the moving groove 8, the limiting block 18 limits the movement of the limiting block 19, so that the air cavity cover 9 is prevented from moving upwards, and the air cavity cover 9 is guaranteed to be connected with the air cavity 7 and not separated all the time. The sealing ring is arranged to ensure the sealing environment inside the moving groove 8.

The first air valve 13 and the second air valve 14 are both one-way air valves, and the first air valve 13 and the second air valve 14 are both located on the inner side of the fixing ring 10. The arrangement of the positions of the first air valve 13 and the second air valve 14 ensures that the air cavity 7 of the air extraction valve 4 is matched with the air cavity cover 9, and the vacuumizing operation is smoothly completed.

The second bag body 2 top symmetry is equipped with easily tears mouth 3, and the setting of easily tearing mouth 3 is convenient for open first bag body 1 and second bag body 2 fast.

During the use, along easily tearing 3 opening the first bag body 1, open sealing strip 6 and take out the second bag body 2. The second bag body 2 is opened along the easy-tear opening 3, and the article stored therein is taken out in a vacuum state. The remained articles which are not used up can be put back into the first bag body 1 again, and the vacuumizing operation is continuously carried out by pressing the air pressing cavity cover 9 after the sealing strip 6 is closed. If the article is used, the first bag body 1 can be used as a vacuum storage bag for other articles.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
