[0025] The effect achieved by the entire embodiment 1 is that when the elastic packaging bag is used, the center plate 1 is used to provide a hard partition for the center position of the packaging bag 1. At the same time, through the coordinated use of the inner elastic layer 3 and the outer elastic layer 4, the inner elastic layer 3 and the outer elastic layer 4 can be compressed or stretched to deform, thereby achieving the purpose of compressing or expanding the storage space size of the packaging bag. When the inner elastic layer 3 and the outer elastic layer 4 are stretched to expand the storage space, the top frame plate 2 and the bottom frame plate 9 are respectively moved to a position away from the center plate 1. At this time, the multiple multi-stage telescopic rods 5 will be in a stretched state. After the stored items are placed inside the packaging bag, the multi-stage telescopic rods 5 are filled in the inner side of the inner elastic layer 3 and the outer elastic layer 4. The multi-stage telescopic rods 5 can play a role of hard support. When multiple packaging bags are stacked and transported, the items next to them will contact the multi-stage telescopic rods 5 inside the packaging bag.

[0028] Working principle: When the elastic packaging bag is used, the center plate 1 is used to provide a hard partition for the center position of the packaging bag 1. At the same time, through the coordinated use of the inner elastic layer 3 and the outer elastic layer 4, the inner elastic layer 3 and the outer elastic layer 4 can be compressed or stretched to deform, thereby achieving the purpose of compressing or expanding the storage space size of the packaging bag. When the inner elastic layer 3 and the outer elastic layer 4 are stretched to expand the storage space, the top frame plate 2 and the bottom frame plate 9 are respectively moved to a position away from the center plate 1. At this time, the multiple multi-stage telescopic rods 5 will be in a stretched state. After the stored items are placed inside the packaging bag, the multi-stage telescopic rods 5 are filled in the inner elastic layer 3 and the outer elastic layer 4. The multi-stage telescopic rod 5 is arranged on the inner side of the elastic layer 4 to play a role of rigid support. When multiple packaging bags are stacked for transportation, the items next to them will come into contact with the multi-stage telescopic rod 5 inside the packaging bag. When the multi-stage telescopic rod 5 is used to realize the rigid support function, the packaging bag can realize its own elastic expansion and contraction, and at the same time, it can provide better support and protection for the stored items after stretching for storage, thereby improving the safety protection effect of the packaging bag on the stored items. When placing items at the bottom of the packaging bag, the matching arrangement of the partition frame 18 and the partition plate 19 can facilitate the partitioning of the bottom of the items, thereby improving the practicality of the packaging bag.
