[0006] In one embodiment, a transparent adhesive film is fixedly connected to the inner wall of the hot melt bonding film, and the surface of the transparent adhesive film is coated with an adhesive.

[0007] In one embodiment, one side of the transparent adhesive film is combined with the inner wall of the hot-melt bonding film to form an embedded groove, the embedded groove being located at the lower end of the longitudinally penetrating vent.

[0008] In one embodiment, the upper end of the embedded groove is connected to the adjacent longitudinal through-vent, and the lower end of the embedded groove is connected to the transverse through-vent.

[0009] In one embodiment, the inner wall of the embedded groove is fitted with a breathable sealing paper, the horizontal cross-section of which is rectangular.

[0010] In one embodiment, the upper end of the breathable sealing paper is provided with a plurality of arc-shaped folding holes, and the plurality of arc-shaped folding holes are evenly distributed in an array along the surface of the breathable sealing paper.

[0011] In one embodiment, the interior of the arc-shaped folding hole is provided with an arc-shaped folding part, which is connected to the breathable sealing paper. Beneficial effects

[0012] 1.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The following is combined Figures 1-5 This invention describes a deoxidizer packaging material with oxygen absorption and color-changing function.

[0024] In one embodiment, an oxygen absorber packaging material with oxygen-absorbing and color-changing function includes: an outer protective film 1, an inner protective film 2 disposed at the lower end of the outer protective film 1, a plurality of longitudinally penetrating vents 11 being arranged in an array at the upper end of the outer protective film 1, a plurality of transversely penetrating vents 21 being arranged at the lower end of the inner protective film 2, and the plurality of transversely penetrating vents 21 being evenly distributed in a straight line along the surface of the inner protective film 2; and a venting mechanism 3 disposed at the lower end of the outer protective film 1 and installed at the upper end of the inner protective film 2; wherein the venting mechanism 3 includes a heat-fused connecting film 31 installed at the lower end of the outer protective film 1.

[0025] It should be noted that: in this device, the hot melt connecting film 31, the outer protective film 1, and the inner protective film 2 can be heat-fused together to form an integral structure by extrusion thermoplastic process during cutting. When the deoxidizer is loaded, the inner protective film 2 is in contact with the deoxidizer, and the outer protective film 1 is in contact with the external gas.

[0026] like Figures 1-4 As shown, the lower end of the hot melt bonding film 31 is fixedly connected to the upper end of the inner protective film 2. A transparent adhesive film 32 is fixedly connected to the inner wall of the hot melt bonding film 31. The surface of the transparent adhesive film 32 is coated with adhesive. One side of the transparent adhesive film 32 is combined with the inner wall of the hot melt bonding film 31 to form an embedded groove 34. The embedded groove 34 is located at the lower end of the longitudinal through vent 11. The upper end of the embedded groove 34 is connected to the adjacent longitudinal through vent 11. The lower end of the embedded groove 34 is connected to the transverse through vent 21.

[0027] In this embodiment, the device uses a longitudinal through-vent 11 and a transverse through-vent 21 to allow external gas to pass through the embedded groove 34 and form a communication effect. Since the longitudinal through-vent 11 and the transverse through-vent 21 are distributed at an alternating 90-degree angle from top to bottom, the leakage of internal deoxidizer is reduced while external gas flows. The transparent adhesive film 32 is coated with adhesive on both sides and is bonded to the adjacent surfaces of the outer protective film 1 and the inner protective film 2. At this time, since the hot melt bonding film 31 and the transparent adhesive film 32 are connected to the outer protective film 1 and the inner protective film 2, the embedded groove 34 forms a cavity without adhesive material with the outer protective film 1 and the inner protective film 2.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, a breathable sealing paper 33 is installed on the inner wall of the embedded groove 34. The horizontal cross section of the breathable sealing paper 33 is rectangular. Multiple arc-shaped folding holes 35 are opened at the upper end of the breathable sealing paper 33. The multiple arc-shaped folding holes 35 are evenly distributed in an array along the surface of the breathable sealing paper 33. An arc-shaped folding part 36 is provided inside the arc-shaped folding hole 35. The arc-shaped folding part 36 is connected to the breathable sealing paper 33.

[0029] In this embodiment, the breathable sealing paper 33 is installed inside the cavity, and the material of the breathable sealing paper 33 can be breathable paper, non-woven fabric, or other polymer material components, which can be appropriately adjusted according to the actual use. External gas can move through the breathable sealing paper 33 towards the internal protective film 2, and both ends of the internal protective film 2 extend to the bottom of the embedded groove 34. The arc-shaped folding holes 35 opened on the surface of the breathable sealing paper 33 can increase the passage of gas through the breathable sealing paper 33, and the arc-shaped folding part 36 reduces the leakage of internal deoxidizer, thus ensuring the effect of deoxidizer storage.

[0030] Working principle: External gas is connected through the embedded groove 34 by the combination of the longitudinal through vent 11 and the transverse through vent 21. The transparent adhesive film 32 is coated with adhesive on both sides and bonded to the adjacent surfaces of the outer protective film 1 and the inner protective film 2. The hot melt bonding film 31 and the transparent adhesive film 32 are connected to the outer protective film 1 and the inner protective film 2. The breathable sealing paper 33 is made of breathable paper. External gas moves through the breathable sealing paper 33 to the transverse through vent 21. The two ends of the inner protective film 2 extend to the bottom of the embedded groove 34. The arc-shaped folding holes 35 opened on the surface of the breathable sealing paper 33 increase the passage of gas through the breathable sealing paper 33. The arc-shaped folding part 36 reduces the leakage of internal deoxidizer.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
