[0024] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0025] Embodiment 1
[0026] As Figures 1 to 3 shown, this embodiment proposes a foamed composite membrane bag for sanitary product packaging, including a membrane bag body 1, a protection component 2 fixed inside the membrane bag body 1, a sealing component 3 fixed on the side of the protection component 2, and a reinforcement component 4 fixed on the side of the membrane bag body 1;
[0027] The protection component 2 includes a membrane bag outer shell 21, a buffer pad 22 fixed on the inner wall of the membrane bag outer shell 21, a protective layer 27 fixed on the topmost layer inside the membrane bag outer shell 21, a foaming layer 23 fixed on the bottom of the protective layer 27, a bioactive layer 24 fixed on the bottom of the foaming layer 23, an antistatic layer 25 fixed on the bottom of the bioactive layer 24, a permeable layer 26 fixed on the bottom of the antistatic layer 25, and a protective layer 27 fixed on the top of the foaming layer 23;
[0028] The material of the foaming layer 23 is polyethylene foam;
[0029] The shape of the buffer pad 22 is semi-circular, and the buffer pads 22 are evenly arranged on the inner wall of the membrane bag outer shell 21;
[0030] The structure of the bioactive layer 24 is a porous structure.
[0031] In this embodiment, when an item is placed in the additional protection component 2 inside the film bag body 1, the buffer pad 22 fixed on the inner wall of the film bag outer shell 21 can provide a certain buffering effect on the item, and at the same time, it can also increase the friction coefficient between the item and the inner wall of the film bag outer shell 21, making the item more stable in the film bag outer shell 21. At the same time, among the protective layer 27, foaming layer 23, bioactive layer 24, anti-static layer 25, and breathable layer 26 sequentially arranged from outside to inside on the inner wall of the film bag outer shell 21, the protective layer 27 can protect the item. The foaming layer 23 has characteristics such as lightness, heat insulation, and sound insulation, and the material of the foaming layer 23 is polystyrene foam, so as to provide a heat preservation effect inside the film bag outer shell 21. The bioactive layer 24 can effectively inhibit the growth of bacteria and molds, thereby protecting the item. The anti-static layer 25 can prevent static adhesion between the item and the inner wall of the film bag outer shell 21, and the breathable layer 26 can keep good air circulation inside the film bag outer shell 21.
[0032] Embodiment 2
[0033] As Figures 4 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the sealing component 3 includes a nozzle opening 31. A lower sealing block 32 is fixed at the bottom of the side of the nozzle opening 31. A sealing strip 33 is fixed inside the lower sealing block 32. An upper sealing block 35 is fixed at the top of the side of the nozzle opening 31. A sealing groove 34 is formed inside the upper sealing block 35;
[0034] Closing strips 36 are clamped on the outer sides of both the upper sealing block 35 and the lower sealing block 32, and the closing strips 36 are used to reinforce the upper sealing block 35 and the lower sealing block 32;
[0035] The reinforcement component 4 includes a reinforcement cover plate 41. A perforation 42 is formed at the top of the reinforcement cover plate 41. A convenient magic tape 43 is fixed on the inner wall of the reinforcement cover plate 41. A magic tape strip 44 is fixed at the top of the film bag body 1;
[0036] The magic tape strip 44 is fixed at a position on the top of the film bag body 1 close to the reinforcement cover plate 41, and the magic tape strip 44 can be attached to the convenient magic tape 43.
[0037] In this embodiment, when the sanitary article is packaged into the protection component 2, the sealing strip 33 inside the lower sealing block 32 is engaged with the sealing groove 34 formed inside the upper sealing block 35, so that a sealed space is formed on the inner wall of the protection component 2. Then, the closing strip 36 is used to fix around the lower sealing block 32 and the upper sealing block 35, thereby preventing the problem of sealing leakage inside the protection component 2. The perforation 42 formed in the reinforcement cover plate 41 fixed to the side of the film bag body 1 is clamped on the sealing component 3, and the convenient magic tape 43 fixed to the inner wall of the other end of the reinforcement cover plate 41 is mutually attached to the magic tape strip 44 fixed to the top of the film bag body 1, so that while the protection component 2 is fixed inside the film bag body 1, the protection component 2 is prevented from detaching from the film bag body 1.
[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
