[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides a transparent film bag with a diaphragm structure, including a transparent film bag body 1, a sealing strip 3 installed on the upper part of the inner walls on both sides of the transparent film bag body 1, and a diaphragm mechanism 4 provided on the inner surface of the transparent film bag body 1. The combination design of the transparent film bag body 1 with the sealing strip 3 and the diaphragm mechanism 4 enables the film bag to have both good sealing performance and internal protection function, which can meet the packaging needs of various items.

[0026] The diaphragm mechanism 4 includes a contact layer 41, a transition layer 42 on one side of the contact layer 41, a barrier layer 43 on one side of the transition layer 42, an adhesive layer 44 on one side of the barrier layer 43, and a protective layer 45 on one side of the adhesive layer 44.

[0027] Specifically, the contact layer 41 is made of polyvinyl chloride, the transition layer 42 is made of maleic anhydride-grafted polypropylene, the barrier layer 43 is made of polyvinylidene chloride, the adhesive layer 44 is made of a special adhesive material, and the protective layer 45 is made of linear polyethylene. The synergistic effect of each layer of the diaphragm mechanism 4 provides comprehensive and multi-layered protection for the item from contact with the item to protection against external damage, effectively extending the shelf life of the item.

[0028] like Figures 1 to 5As shown, the contact layer 41 is located at the innermost side of the transparent film bag body 1, and the surface of the contact layer 41 is provided with an anti-slip coating 411. The anti-slip coating 411 is composed of several protrusions. The anti-slip coating 411 on the surface of the contact layer 41 increases the friction between the contact layer 41 and the item, preventing the item from sliding or tipping over inside the film bag and improving the stability of the packaged item.

[0029] Furthermore, a label 2 is provided on one side of the outer surface of the transparent film bag body 1. The label 2 makes it easy for users to quickly understand the relevant information of the items inside the film bag, such as name, specifications, and usage methods, thus improving the ease of use.

[0030] like Figures 1 to 5 As shown, the sealing strip 3 includes a channel 31 fixedly connected to one side of the transparent film bag body 1, and a strip 34 fixedly connected to the inner wall of the other side of the transparent film bag body 1. Both the strip 34 and the channel 31 are made of rubber. The elasticity of the rubber allows them to fit tightly during sealing, which enhances the sealing performance of the film bag and prevents leakage of items and entry of external impurities.

[0031] It is worth noting that several elastic blocks 33 are fixedly connected to the upper and lower ends of the locking strip 34. The upper and lower inner walls of the locking channel 31 are provided with grooves 32 that cooperate with the several elastic blocks 33. The several elastic blocks 33 and the several grooves 32 are all hemispherical. The cooperation between the elastic blocks 33 and the grooves 32 further improves the sealing effect of the sealing strip 3. The hemispherical design makes the locking tighter and can still maintain good sealing performance after multiple opening and closing.

[0032] Working principle and process: When a transparent film bag is needed, first place the item inside the film bag. The contact layer 41 contacts the item, and the anti-slip coating 411 provides anti-slip protection. Next, align the clip 34 with the clip 31 and press it down. The elastic block 33 is inserted into the groove 32. The elasticity of the rubber makes the sealing strip 3 fit tightly, thus sealing the film bag. The barrier layer 43 in the diaphragm mechanism 4 isolates external air and moisture. The protective layer 45 prevents the film bag from being physically damaged by the outside. The adhesive layer 44 ensures a stable connection between the layers. The transition layer 42 promotes compatibility between different material layers, thus providing all-round protection for the item. The label 2 allows the user to easily view relevant information about the item inside the film bag.
