[0020] 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.

[0021] Example 1

[0022] Please see Figures 1-2This utility model provides the following technical solution: a bubble wrap with a long service life, comprising a base layer 1, a first hot melt adhesive film layer 2 connected to the upper surface of the base layer 1, a second hot melt adhesive film layer 3 connected to the upper surface of the first hot melt adhesive film layer 2, both the first hot melt adhesive film layer 2 and the second hot melt adhesive film layer 3 being TPU (thermoplastic polyurethane) hot melt adhesive film (hot melt adhesive film produced by Zhenjiang Tianmei New Material Co., Ltd.), the second hot melt adhesive film layer 3 having a plurality of equally spaced protrusions 5, after the first hot melt adhesive film layer 2 and the second hot melt adhesive film layer 3 are connected, the interior of the protrusions 5 is a sealed hollow structure, the upper surface of the second hot melt adhesive film layer 3 is connected to a surface layer 4, the thickness of the first hot melt adhesive film layer 2 and the second hot melt adhesive film layer 3 is 0.1mm, the thickness of the base layer 1 is 1mm, and the thickness of the surface layer 4 is 0.5mm.

[0023] In this embodiment, the method for forming the protrusion 5 on the second hot melt adhesive film layer 3 is as follows: the TPU hot melt adhesive film is placed in a hot press mold, heated to about 50°C to soften the TPU hot melt adhesive film, and then pressure is applied for about 30 seconds with a pressure of 0.3 MPa. After cooling, the film is demolded and formed.

[0024] By adopting the above technical solution, the bottom pad layer 1, the first hot melt adhesive film layer 2, the second hot melt adhesive film layer 3, and the pad surface layer 4 of this utility model are laminated together. After lamination, the inside of the protrusion 5 forms a sealed hollow structure, thereby playing the role of a pad or cushion. Compared with the inflatable pads in the prior art, the protrusion 5 of this utility model is an individual unit and does not interfere with each other. Even if one of the protrusions 5 is damaged, it will not affect the functionality of the other protrusions 5, thereby effectively increasing the service life.

[0025] It should be noted that the lamination temperature is around 95℃, the lamination pressure is around 0.5MPa, the heating time is around 15s, and then it is naturally cooled to below 40℃ for demolding. This ensures the strong adhesion and avoids the degradation of the hot melt adhesive film layer and the deformation of the base layer 1 and the surface layer 4.

[0026] Specifically, protrusion 5 has a spherical crown-shaped structure, and in this embodiment, it is preferably a hemispherical structure.

[0027] By adopting the above technical solution, comfort can be increased, and the space between the protrusions 5 can be used for ventilation.

[0031] The difference between this embodiment and embodiment 1 is that, specifically, the bottom pad layer 1 is a silicone layer or a rubber layer, and in this embodiment, a silicone layer is preferred.

[0032] The above technical solution is used to achieve a waterproof effect.

[0033] Example 4

[0034] The difference between this embodiment and embodiment 1 is that the material of the pad surface layer 4 includes, but is not limited to, natural fibers (such as cotton, linen or silk), regenerated fibers (modal or viscose fiber) or synthetic fibers (micro denier polyester fiber or spandex blend).

[0035] By adopting the above technical solution, it has a good skin-friendly effect and further increases comfort.

[0036] Example 5

[0037] The difference between this embodiment and embodiment 1 is that the material of the pad surface layer 4 includes, but is not limited to, bamboo fiber, flax or hemp fiber.

[0038] By adopting the above technical solution, the surface layer 4 of the pad has a natural antibacterial or bacteriostatic effect.

[0039] In summary, the bottom pad layer 1, the first hot melt adhesive film layer 2, the second hot melt adhesive film layer 3, and the surface layer 4 of this invention are laminated together. After lamination, the interior of the protrusions 5 forms a sealed hollow structure, thus serving as a pad or cushion. Compared to inflatable pads in the prior art, the protrusions 5 of this invention are individual units that do not interfere with each other. Even if one protrusion 5 is damaged, it does not affect the functionality of the other protrusions 5, thereby effectively increasing the service life. The protrusions 5 of this invention have a spherical crown structure, which can be used to increase comfort, and the space between the protrusions 5 can be used for breathability. The bottom pad layer 1 of this invention is a silicone layer or a rubber layer, preferably a silicone layer, for achieving a waterproof effect. The material of the surface layer 4 of this invention includes, but is not limited to, natural fibers, regenerated fibers, or synthetic fibers, which have good skin-friendly effects and further increase comfort.
