[0019] In order to further explain the technical solution of the present utility model, specific embodiments are described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1-4 The utility model provides a high-strength PE film packaging bag, comprising an outer bag 1 and an inner bag 2 arranged in the outer bag 1, a cavity that can surround the inner bag 2 is formed between the outer bag 1 and the inner bag 2, the upper end of the inner bag 2 is fixedly connected to the upper end of the outer bag 1, a connecting piece 3 is arranged at the lower end of the inner bag 2, the lower end of the connecting piece 3 is fixedly connected to the inner surface of the outer bag 1, a suction nozzle 4 is arranged at the upper end of the outer bag 1, the suction nozzle 4 is threadedly connected to the sealing cover 5, an extrusion mechanism is arranged in the cavity, the lower end of the inner bag 2 is funnel-shaped, and a partition 6 is arranged at the lower end of the inner bag 2; the crushed jelly is placed in the inner bag 2, and the inner bag 2 can be squeezed from bottom to top by the extrusion mechanism, so that the partition 6 gradually rises, thereby pushing the jelly on the partition 6 to rise, so that it can be sucked.

[0021] Furthermore, the squeezing mechanism includes a first support rod 7 and a second support rod 8 which are arranged in the cavity at the front and rear sides of the inner bag 2, and a pull rod 9 is fixedly arranged at both ends of the first support rod 7. The pull rod 9 passes through the tightening holes 10 arranged at both ends of the second support rod 8 and the through hole 11 arranged on the outer bag 1, and triangular clamping teeth 12 are evenly distributed on the pull rod 9. A clamping plate 13 is arranged at the upper end of the tightening hole 10 to be clamped between the clamping teeth 12. The first support rod 7, the second support rod 8, the pull rod 9, the clamping teeth 12 and the clamping plate 13 are all made of hard rubber; by pulling the pull rod 9 in the through hole 11 of the outer bag 1 outward, the first support rod 7 and the second support rod 8 can be brought close to each other, and the clamping plate 13 is clamped between the clamping teeth 12, so that the first support rod 7 and the second support rod 8 are not easy to move relative to each other, and then the first support rod 7 and the second support rod 8 are held and pushed upward, so that the partition 6 in the inner bag 2 moves upward, pushing the jelly to move upward, so that it is easy to be sucked.

[0022] Furthermore, a strip groove 14 is provided in the middle of the front and rear sides of the outer bag 1, and an auxiliary piece 15 is fixedly provided at the lower end of the outer bag 1; the auxiliary piece 15 can be pulled by one hand, and the first support rod 7 and the second support rod 8 in the strip groove 14 on the front and rear sides of the outer bag 1 can be held with the other hand, and then pushed upward to make the partition 6 in the inner bag 2 gradually rise, thereby pushing the jelly on the partition 6 to rise so that it can be sucked.

[0023] Furthermore, the outer bag 1 includes a wear-resistant layer and a heat-insulating layer from the outside to the inside, and the inner bag 2 includes a wear-resistant layer, a heat-insulating layer and an antibacterial layer from the outside to the inside. The wear-resistant layer of the outer bag 1 and the wear-resistant layer of the inner bag 2 can make the packaging bag wear-resistant.

[0024] When in use, unscrew the sealing cover 5, suck the jelly in the inner bag 2, and then pull the pull strip 9 in the through hole 11 of the outer bag 1 outwards to make the first support rod 7 and the second support rod 8 close to each other, hold the auxiliary sheet 15 with one hand, hold the first support rod 7 and the second support rod 8 in the strip grooves 14 on the front and back sides of the outer bag 1 with the other hand, and then push upwards to make the partition 6 in the inner bag 2 gradually rise, thereby pushing the jelly on the partition 6 to rise so that it can be sucked, thereby avoiding waste.
