[0024] The content of the utility model will be further explained in detail in combination with specific embodiments:

[0025] In order to achieve the purpose of the utility model, a parallel double-bottle packaging combined palm film comprises: a first film tube 3. A second film tube 4 is arranged in parallel with the first film tube 3, and the inner cavity cross-sectional area of the second film tube 4 is greater than that of the first film tube 3 in the expanded state. Among them, the first film tube 3 is composed of a first bent film section 10 and an intermediate film section 5 closed loop, the second film tube 4 is composed of a second bent film section 11 and an intermediate film section 5 closed loop, and the first film tube 3 and the second film tube 4 share the intermediate film section 5. The first film tube 3 and the second film tube 4 are in an unfolded state of a sheet film 1, the sheet film 1 has two parallel palm lines, and the two side edges of the sheet film 1 are combined with the palm lines to form the first film tube 3 and the second film tube 4.

[0026] Two palm lines are formed by the palm technology, so that the sheet film 1 presents two cylindrical shapes, thereby realizing the parallel double-bottle combined product packaging structure, so as to make up for the vacancy of this technology in the market. Figures 1 to 2 The whole process is from the state of the first bottle 6 and the second bottle 7 being covered by the sheet film 1.

[0027] As shown in Figure 2 , the first bottle 6 and the second bottle 7 can be wrapped and covered on the product or the outer package, which forms protection for the product or the outer package.

[0028] In other embodiments of the utility model, the first bent film section 10 and the second bent film section 11 are each C-shaped bending, the first bent film section 10 and the second bent film section 11 are bent towards the same side direction of the sheet film 1, and the end of the second bent film section 11 is in contact with and fixed to the first bent film section 10.

[0029] The beneficial effect of adopting the above technical solution is that the bending direction is easy to achieve in the process.

[0030] like Figure 4 As shown, in some other embodiments of this utility model, the two clasping lines are respectively glue lines 9 located on the front and back sides of the sheet film 1. The sheet film 1 is rectangular in shape. A pair of opposite sides of the sheet film 1 contact and adhere to the glue lines 9, and the contact and adhesion point forms a seam 2.

[0031] The advantages of adopting the above technical solution are: the rectangular structure facilitates standardized production, the glue line 9 enables rapid bonding, the application of glue on both sides enhances sealing, the joints are strong and the process is simple, making it suitable for mass production.

[0032] In some other embodiments of this utility model, when the first film tube 3 and the second film tube 4 are in the open state, from an axial perspective along the first film tube 3 and the second film tube 4, the first bent film segment 10 and the second bent film segment 11 are C-shaped, and the intermediate film segment 5 is a line segment. From an axial perspective along the first film tube 3 and the second film tube 4, the length of the intermediate film segment 5 is less than the length of the C-shaped trajectory of the first film tube 310.

[0033] The beneficial effects of adopting the above technical solution are: the C-shaped bend provides an elastic buffer space to adapt to the bottle contour, the middle membrane section is shorter than the C-shaped trajectory, making the axial structure of the film tube compact and easy to stably wrap the bottle after being stretched.

[0034] like Figure 3 As shown, in some other embodiments of this utility model, the first membrane tube 3 and the second membrane tube 4 are in a flattened state. When the first membrane tube 3 and the second membrane tube 4 are in the flattened state, there is a raised crease 8 on the outer wall of each of the first membrane tube 3 and the second membrane tube 4. The raised crease 8 is parallel to the clasp line.

[0035] The beneficial effects of adopting the above technical solution are: the positive crease serves as a flattening and positioning reference, which makes it easier for the film to maintain a regular shape after folding, reduces the space occupied in transportation and storage, and can quickly restore the tubular structure when unfolded.

[0036] In some other embodiments of this utility model, when the first film tube 3 and the second film tube 4 are in a flattened state, the positive crease 8 on the first film tube 3 divides the first film tube 3 into two equal parts, and the length difference of the second film tube 4 on both sides of the positive crease 8 on the second film tube 4 is equal to the length of the middle film segment 5. This ensures that the first film tube 3 and the second film tube 4 are flattened.

[0037] The beneficial effects of adopting the above technical solution are: by accurately positioning the creases, it is ensured that the double film tubes are flattened symmetrically and evenly, avoiding packaging deformation caused by structural offset, and improving the flatness and stability of the packaging.

[0038] In some other embodiments of the present application, the sheet film 1 is a heat-shrinkable film, the first film tube 3 and the second film tube 4 are provided for the bottle to pass through, and the inner diameter of the first film tube 3 in the expanded state is greater than the outer diameter of the bottle inside the first film tube 3, and the inner diameter of the second film tube 4 in the expanded state is greater than the outer diameter of the bottle inside the second film tube 4.

[0039] The beneficial effects of the above technical solution are that the heat-shrinkable property makes the film tightly fit the bottle after shrinking, providing firm protection. The large inner diameter design facilitates quick bottle installation, is compatible with different specifications of bottles, and is flexible and efficient in operation.

[0040] In some other embodiments of the present application, the sheet film 1 is made of PET material.

[0041] The beneficial effects of the above technical solution are that the PET material has high transparency, stretch resistance and chemical resistance, ensuring the appearance and durability of the package, and meeting the environmental protection requirements. It is recyclable and suitable for heat-shrinking process, and has a wide range of applications.

[0042] Figure 4 The dashed line represents the palm line, not that the palm line is intermittent and easy to tear. The dashed line is only used to express the position of the palm line.

[0043] The production process of the palm film of the present application is as follows: first, the sheet film 1 is conveyed to the equipment through the conveying belt and the synchronous wheel, then the corresponding technical parameters are set on the palm equipment, and the angle of the glue spray head and the glue brush head on the equipment is adjusted. The palm line corresponding to the small bottle is realized by glue spraying through the glue spray head, and the palm line corresponding to the large bottle is realized by glue brushing through the glue brush head. After the equipment is debugged, the glue spray head and the glue brush head synchronously apply glue to both sides of the sheet film 1, forming two palm lines, and finally making the sheet film 1 present two cylindrical shapes, thereby realizing the parallel double-bottle combined product packaging structure.

[0044] The palm film of the present application can not change the shrinkage property of the film, and can form two palm lines through the palm technology to make the film present two cylindrical shapes, thereby realizing the purpose of the parallel double-bottle combined product packaging structure, and without damaging the product or the outer packaging. The structure is practical and has a wide application prospect. First, two palm lines are formed through the palm technology to make the sheet film 1 present two cylindrical shapes, thereby realizing the parallel double-bottle combined product packaging structure, and making up for the vacancy of this technology in the market. Second, the material is reduced, and there is a part of the shared packaging material. With the accumulation of days and months, the amount of plastic film is reduced, which meets the environmental protection trend. Finally, the transportation and storage space is saved, the small bottles are fixed on one side of the large bottles in parallel, the overall packaging volume is reduced, and the logistics and storage costs are reduced.

[0045] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
