[0002] Polyethylene foam, also known as EPE pearl cotton, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles generated through physical foaming of low-density polyethylene resin, overcoming the shortcomings of ordinary foam such as fragility, deformation, and poor resilience.

[0003] Existing pearl cotton boards with a certain shape and hardness usually have a certain thickness. When used, they use their rigid sidewalls to protect and cushion the packaged goods. The function of such pearl cotton boards is relatively simple. When used, they can only provide overall protection and shock absorption, and it is difficult to shape and protect local parts of the goods. To solve this problem, bubble wrap is usually wrapped around local parts of the goods. This solution increases the packaging difficulty and the packaging positioning effect is poor.

[0004] Therefore, this utility model provides a pearl cotton with a bubble film layer. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pearl cotton with a bubble film layer to solve the problems mentioned in the background technology. This utility model has the functions of soft and hard protection, which not only improves the protective effect, but also expands the scope of protection application, and has the advantage of being more convenient to recycle and reuse.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a pearl cotton with a bubble film layer, comprising a pearl cotton board one and a pearl cotton board two, wherein the pearl cotton board one is located on one side of the pearl cotton board two and the two are connected by a snap-fit ​​part, a shock-absorbing cavity is provided on the side of the pearl cotton board one opposite to the pearl cotton board two, the shock-absorbing cavity is filled with a bubble film, a buffer window is provided on one side of the pearl cotton board one at intervals and communicating with the shock-absorbing cavity, and a bubble protrusion is provided on one side of the bubble film, which is located in the buffer window and is uniformly distributed.

[0007] Furthermore, bubble protrusions are provided on both sides of the bubble film, and the bubble protrusions on both sides of the bubble film are symmetrically arranged relative to the bubble film.

Several snap posts are fixedly installed on one side of the second pearl cotton board near the edge and on one side of the pad. A snap groove opposite to the snap post is opened on one side of the first pearl cotton board. A clearance hole adapted to the snap post is opened on the bubble film.

[0010] Furthermore, the locking pin has a pagoda-shaped structure, and the locking slot has several annular grooves distributed axially.

[0011] Furthermore, the top of the bubble protrusion is flush with the outer layer of the pearl cotton board.

[0012] Furthermore, the buffer window contains a protective film that is bonded to the corresponding bubble protrusion.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, by sandwiching bubble film between pearl cotton board one and pearl cotton board two, the protective, shock-absorbing and cushioning performance of the pearl cotton is greatly improved. Then, a cushioning window is opened on one side of the pearl cotton board, and the bubble protrusions on the bubble film are located in the cushioning window. This arrangement gives the pearl cotton a plastic soft protection function on one side and a hard cushioning protection function on the other side, thereby improving the applicability of the pearl cotton.

[0015] 2. In this utility model, the first and second pearl cotton boards are connected by a snap-fit ​​part. Then, a shock-absorbing cavity for accommodating the bubble wrap is opened on one side of the first pearl cotton board. The bubble wrap is placed inside the shock-absorbing cavity.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a pearl cotton with a bubble film layer, including pearl cotton board 1 and pearl cotton board 2. Pearl cotton board 1 and pearl cotton board 2 are rectangular board structures. Pearl cotton board 1 is located on one side of pearl cotton board 2 and the two are connected by a snap-fit ​​part 5. That is to say, pearl cotton board 1 and pearl cotton board 2 have the function of easy disassembly and assembly.

[0023] Furthermore, a shock-absorbing cavity 3 is provided on the side of the pearl cotton board 1 opposite to the pearl cotton board 2. The shock-absorbing cavity 3 is filled with bubble film 4. The function of bubble film 4 is to increase the shock-absorbing and protective strength of the board body composed of pearl cotton board 1 and pearl cotton board 2.

[0024] The pearl cotton board 1 has a buffer window 11 that is spaced apart and connected to the shock absorption cavity 3 on one side. That is, the pearl cotton board 1 has at least two buffer windows 11 arranged in a row. The bubble film 4 has bubble protrusions 41 that are evenly distributed inside the buffer window 11 on one side. The top of the bubble protrusions 41 is flush with the outer layer of the pearl cotton board 1. The bubble protrusions 41 are composed of bubbles arranged in a matrix. The bubble protrusions 41 give the pearl cotton a plastic soft protection function. When it is necessary to protect the product as a whole, the other side of the pearl cotton board 2 can be in contact with the product. When it is necessary to provide plastic protection for the product, the bubble protrusions 41 can be in contact with the product. The bubbles on the bubble protrusions 41 will deform to adapt to the structure of the product.

[0025] Furthermore, bubble protrusions 41 are provided on both sides of the bubble membrane 4. The bubble membrane 4 uses the bubble protrusions 41 to fill the shock-absorbing cavity 3. The bubble protrusions 41 on both sides of the bubble membrane 4 are symmetrically arranged relative to the bubble membrane 4, which improves the shock absorption strength of this pearl cotton.

[0026] Among them, a pad 21 is fixedly connected to the side of the pearl cotton board 2 opposite to the shock absorption cavity 3. The pad 21 is located between adjacent bubble protrusions 41. The pad 21 can eliminate the empty part in the shock absorption cavity 3, and at the same time limit the bubble film 4, which is convenient for assembly. It can also effectively prevent the bubble film 4 from moving in the shock absorption cavity 3.

[0027] In this embodiment, the snap-fit ​​part 5 includes a snap groove 51 and a snap post 52. Several snap posts 52 are fixedly provided on one side of the pearl cotton board 2 near the edge and on one side of the pad 21. A snap groove 51 opposite to the snap post 52 is opened on one side of the pearl cotton board 1. A clearance hole 42 adapted to the snap post 52 is opened on the bubble wrap 4. When the snap post 52 and the snap groove 51 are snapped together, the pearl cotton board 1 and the pearl cotton board 2 are combined into a whole. After the two are separated, the bubble wrap 4 can be taken out, which makes it convenient to use the combined state of the pearl cotton board 1 and the pearl cotton board 2 alone and to use the bubble wrap 4 alone. It also facilitates subsequent classification and recycling.

[0028] Furthermore, the locking pin 52 has a pagoda-shaped structure, and the locking groove 51 has several axially distributed annular grooves 511. This design can improve the relaxation effect after the locking pin 52 and the locking groove 51 are engaged.

[0029] In this embodiment, the buffer window 11 contains a protective film 6 that is bonded to the corresponding bubble protrusion 41. The material of the protective film 6 is the same as that of the bubble film 4. The function of the protective film 6 is to connect the tops of all the bubbles on the bubble protrusion 41. The protective film 6 is supported by the bubble protrusion 41. When protecting the product, the protective film 6 will come into contact with the product over a large area, further improving the protective performance.

[0030] Working principle: When soft protection is needed for goods in a packaging box, place the pearl cotton inside the box, then position the bubble protrusions 41 opposite the goods, pressing them against the goods for soft protection. Simultaneously, the pearl cotton provides overall hard protection for the goods. When only hard protection is needed, simply place the pearl cotton with the bubble protrusions 41 facing away from the goods. When using bubble wrap 4 alone, manually peel off pearl cotton board 1 and pearl cotton board 2, then remove bubble wrap 4 for use.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
