[0032] The utility model can be implemented in the following way:

[0033] Referring to Figures 1-3 A film packaging inner liner capable of forming a box body, comprising a bottom plate 1 and a film 2 arranged above the bottom plate 1.

[0034] The bottom plate 1 comprises a carrier plate 11, pull-out plates 12 arranged on the left and right sides of the carrier plate 11, a front folding plate 13 and a rear folding plate 14 arranged on the front and rear sides of the carrier plate 11 respectively, and a movable tension plate 15 arranged on the other side of the front folding plate 13. The movable tension plate 15 is separated from the front folding plate 13. The carrier plate 11 is connected to the pull-out plates 12, the front folding plate 13 and the rear folding plate 14 through creases. The bottom plate 1 further comprises a front shock-absorbing plate 16 and a rear shock-absorbing plate 17 connected to the creases on the two sides of the pull-out plates 12. The rear shock-absorbing plate 17 is connected to the crease of the rear folding plate 14. The design that the front shock-absorbing plate 16 and the rear shock-absorbing plate 17 can be folded backward makes the front shock-absorbing plate 16 and the rear shock-absorbing plate 17 able to abut against the two side surfaces in the packaging box through friction, thereby ensuring that the entire film packaging inner liner can be fixed in the packaging box without shaking.

[0035] The two sides of the film 2 are respectively adhered to the top surfaces of the rear folding plate 14 and the movable tension plate 15. The film 2 and the carrier plate 11 form a containing space for containing a product 3. The product 3 can be placed between the film 2 and the carrier plate 11, and then the film 2 is wound and fixed to the product 3 through the rotation of the movable tension plate 15, thereby ensuring that the product 3 does not shake during transportation, and thus effectively fixing the product 3.

[0036] Referring to Figures 4a-4d, the whole film packaging liner can switch between the unfolded state and the packaging state by folding. In the packaging state, the front and rear folding plates 13 and 14 are folded to the back of the carrier plate 11, the front and rear shock-absorbing plates 16 and 17 are folded to the back of the pull plate 12 and are attached to the pull plate 12, and the movable tension plate 15 is rotated several turns towards the rolled film 2 and is hidden in the back of the carrier plate 11, and its two sides are inserted into the gap between the pull plate 12 and the front and rear shock-absorbing plates 16 and 17, and the two pull plates 12 are folded towards each other and are perpendicular to the carrier plate 11.

[0037] Referring to Figure 1 , in the unfolded state, the length of the film 2 is greater than or equal to the total length of the rear folding plate 14, the carrier plate 11 and the movable tension plate 15. In the unfolded state, the length of the film 2 is equal to the total length of the rear folding plate 14, the carrier plate 11 and the front shock-absorbing plate 16 in the embodiment. The film packaging liner can determine the number of turns of the movable tension plate 15 according to the volume and height of the product 3, so that the product 3 can be fixed between the film 2 and the carrier plate 11 when the film 2 is pulled tight. When the product 3 is large in volume or high in height, the number of turns of the movable tension plate 15 rolling the film 2 is reduced; on the contrary, when the product 3 is small in volume or low in height, the number of turns of the movable tension plate 15 rolling the film 2 is increased; in addition, if the height of the product 3 is too high, the length of the film 2 can be directly replaced to fix it, so that the film 2 can wrap the product 3. The length of the film 2 can be adjusted according to the height and volume of the product 3, further increasing the application range of the film packaging liner.

[0038] In order to ensure that the movable tension plate 15 can be fixed on the back of the carrier plate 11 after rolling the film 2, the movable tension plate 15 is provided with fixed insertion strips 151 on both sides, which can be inserted into the gap between the pull plate 12 and the front and rear shock-absorbing plates 16 and 17 in the packaging state. The movable tension plate 15 is connected with the fixed insertion strips 151 by folding. When the movable tension plate 15 rolls and tightens the film 2, the movable tension plate 15 is rotated to the back of the carrier plate 11 (as shown in Figure 4c ), and the fixed insertion strips 151 at both ends are clamped in the gap between the pull plate 12 and the front and rear shock-absorbing plates 16 and 17 (as shown in Figure 4d ).

[0039] Referring to Figure 3In the unfolded state, the fixing strip 151 and the front shock-absorbing plate 16 are spliced ​​together to form a rectangle. The movable tension plate 15 is cut from the base plate 1. The fixing strip 151 is triangular, and the free edge of the front shock-absorbing plate 16 has a chamfer on the side near the movable tension plate 15, which is the same shape and size as the fixing strip 151. This design, as can be seen from the unfolded state, shows that the entire base plate 1 of the film packaging liner, including the carrier plate 11, the lifting plate 12, the front folding plate 13, the rear folding plate 14, the movable tension plate 15, the front shock-absorbing plate 16, and the rear shock-absorbing plate 17, is all cut and folded from a rectangular corrugated cardboard. The cutting only requires 6 cuts to make the base plate 1, which maximizes the use of material to achieve a fixed cushioning effect, and the folding process is also convenient and quick.

[0040] To facilitate the recycling of the film packaging liner, the base plate 1 is made of corrugated cardboard. The film 2 is made of at least one of OPS, PE, PVC, POF, and PET. This design allows the entire packaging box, including the base plate 1, film 2, and box body, to be recycled, achieving the goal of environmental protection.

[0041] Production method: First, fold a tic-tac-toe pattern on a rectangular piece of corrugated cardboard. Alternatively, you can pre-fabricate the tic-tac-toe pattern using a machine. Then, along... Figure 3 Cut along the two first cutting lines 01 and the second cutting line 02 to form the front shock-absorbing plate 16; cut along the third cutting line 03 and the fourth cutting line 04 to form the front folding plate 13 and the movable tensioning plate 15. This base plate 1 only requires 6 cuts. Next, attach the two sides containing the short sides of the film 2 to the top surface of the rear folding plate 14 and the movable tensioning plate 15 to form the film packaging liner in the unfolded state (e.g., ...). Figure 1 (As shown).

[0042] Reference Figure 5 A packaging box includes a box body 4, the contents of which are filled with a film packaging liner as described above. The size of the box body 4 should be adapted to the film packaging liner in its packaged state, so that the film packaging liner in its packaged state can be just placed inside the box body 4. That is, the bottom surface of the box body 4 should be slightly larger than the carrying plate 11, and the height should be adapted to the height of the lifting plate 12.

[0043] Instructions for use: Refer to... Figures 4a-4d First, fold the front folding plate 13 and the rear folding plate 14 along the creases toward the back of the carrier plate 11, while simultaneously folding the front shock-absorbing plate 16 and the rear shock-absorbing plate 17 toward the back of the lifting plate 12 and fitting them together; then place the product 3 between the film 2 and the carrier plate 11, and after the movable tensioning plate 15 rotates several times toward the direction of winding the film 2, it is hidden behind the carrier plate 11 (rotation direction as follows). Figure 4band make its two sides inserted into the gap between the pulling plate 12 and the front shock-absorbing plate 16 and the rear shock-absorbing plate 17; then fold the two pulling plates 12 towards each other and perpendicular to the object-carrying plate 11 (as shown in Fig. 6).
