Description

Technical Field

[0001] The utility model belongs to the technical field of bubble wrap, and particularly relates to a new type of environmentally friendly bubble wrap that is convenient for splicing. Background Technique

[0002] Bubble wrap is a material widely used in the packaging industry. It is mainly made of high-pressure polyethylene as the base material and is formed by extruding and thermoforming into bubbles at a high temperature of about 230 degrees. It can effectively isolate moisture and protect the packaged items from getting wet. It also has good shock absorption and impact resistance, and can effectively protect fragile or valuable items.

[0003] Traditional bubble wrap is extruded and thermoformed into several bubbles on a layer of plastic film, and these bubbles are used for buffering and shock absorption. After traditional bubble wrap is produced and formed, it is wound and stored in a certain width and length. When used for packaging, it is cut into small pieces. After the small piece of bubble wrap wraps the item, the edge is easy to warp and needs to be glued with tape or the like to complete the splicing.

[0004] After the small piece of bubble wrap wraps the item, it is generally adhered to each other at the edge with a magic tape. The magic tape is composed of a nylon base cloth and barbs on the nylon base cloth. The barbs need to stand vertically on the nylon base cloth, which increases the thickness at the splicing part of two adjacent small pieces of bubble wrap after the two magic tapes are adhered, and is not conducive to the smooth bending at the splicing part. Therefore, we propose a new type of environmentally friendly bubble wrap that is convenient for splicing. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new type of environmentally friendly bubble wrap that is convenient for splicing. At the splicing part, the thickness increase is not obvious when tied tightly with silk thread, and a gap is left, which is conducive to the smooth bending at the splicing part.

[0006] The technical solution adopted by the utility model is specifically as follows:

[0007] A new type of environmentally friendly bubble film that is convenient for splicing, including a film layer. On both sides of the film layer, a number of bubble sacs are fixedly arranged at intervals. Two groups of first rubber rings are respectively embedded and installed on both sides of the film layer. Each group of several first rubber rings is arranged in a longitudinal array. Two groups of second rubber rings are respectively embedded and installed on the other two sides of the film layer. Each group of several second rubber rings is arranged in a transverse array. When packaging items, take several film layers, and the first rubber rings at the edges overlap each other or the second rubber rings overlap each other. Use a single-strand silk thread to pass through these overlapping first rubber rings or second rubber rings in a wavy shape, extending to the entire edge of the film layer. Then, respectively bypass the adjacent first rubber rings or second rubber rings at both ends of the silk thread and tie them tightly. Or, align the edges of adjacent film layers, use a single-strand silk thread to alternately pass through the first rubber rings or second rubber rings in a wavy shape, and then tie the two ends of the silk thread tightly respectively, so as to tie two adjacent film layers to complete splicing. The thickness increase at the splicing part is not obvious when tied with a silk thread, and there is a gap between adjacent first rubber rings or second rubber rings, which is beneficial to the smooth bending at the splicing part. After splicing, a large bubble film is formed, which can tightly wrap items of different sizes.

[0008] On both sides of the film layer, at positions outside the two groups of first rubber rings, first rubber sheets are also fixed. The first rubber sheets are all penetrated by adjacent first rubber rings. There is a distance between the first rubber sheets and adjacent bubble sacs. The thickness of the first rubber sheet is less than 0.2 mm. Tightening can be carried out by bonding between each first rubber ring, and the two edges of the film layer are structurally strengthened to reduce the occurrence of cracking.

[0009] On both sides of the film layer, at positions outside the two groups of second rubber rings, second rubber sheets are also fixed. The second rubber sheets are all penetrated by adjacent second rubber rings. There is a distance between the second rubber sheets and adjacent bubble sacs. The thickness of the second rubber sheet is less than 0.2 mm. Tightening can be carried out by bonding between each second rubber ring, and the other two edges of the film layer are structurally strengthened to reduce the occurrence of cracking.

[0010] At least one glass nylon thread is inserted between each group of first rubber rings. Use a glass nylon thread that is close to transparent color to wind around each first rubber ring or second rubber ring, without obvious color difference, which is convenient for the appearance of the formed bubble film after splicing to maintain color consistency.

[0011] One end of the glass nylon thread is fixed with a ring-shaped part, and the outer diameter of the ring-shaped part is larger than the inner diameter of the first rubber ring and the inner diameter of the second rubber ring.

[0012] The outer edges of the first rubber ring and the second rubber ring both have rounded corners, which can contact the glass nylon thread or the silk thread with an arc surface, reduce the cutting effect during mutual friction, and reduce the occurrence of the glass nylon thread or the silk thread being cut off.

[0013] The technical effects achieved by the present utility model are:

[0014] The utility model discloses a novel environment-friendly bubble film which is easy to splice. When packaging articles, several film layers are taken, the first rubber rings at the edges of each other overlap with each other or the second rubber rings overlap with each other, a single strand of silk thread is used to pass through the overlapping first rubber rings or second rubber rings in a wavy shape, extending to the entire edge of the film layer, and then the two ends of the silk thread are respectively passed around the adjacent first rubber rings or second rubber rings to be knotted and fastened. Alternatively, the edges of adjacent film layers are aligned, a single strand of silk thread is used to pass through the first rubber rings or second rubber rings alternately in a wavy shape, and then the two ends of the silk thread are respectively knotted and fastened, so that two adjacent film layers can be tied to complete the splicing. The thickness of the splicing part is not significantly increased by using the silk thread to tie, and intervals are left between the adjacent first rubber rings or second rubber rings, which is conducive to smooth bending of the splicing part. After splicing, a large bubble film is formed, which can tightly wrap articles of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0022] like Figures 1-4As shown in the figure, a new type of environmentally friendly bubble film that is convenient for splicing includes a film layer 1. The film layer 1 can be made of high-pressure polyethylene material. A number of bubble bags 2 are fixedly arranged at intervals on both sides of the film layer 1. The bubble bags 2 and the film layer 1 are made of the same material. Two groups of first rubber rings 3 are respectively embedded and installed on both sides of the film layer 1. Each group of several first rubber rings 3 is arranged in a longitudinal array. Two groups of second rubber rings 4 are respectively embedded and installed on the other two sides of the film layer 1. Each group of several second rubber rings 4 is arranged in a transverse array. The second rubber rings 4 and the first rubber rings 3 can both be made of materials such as silica gel. When the film layer 1 leaves the factory, it is cut into sheets of a specified size, and then the first rubber rings 3 and the second rubber rings 4 are added. When packing items, several film layers 1 are taken. The first rubber rings 3 at the edges of each other overlap or the second rubber rings 4 overlap. A single-strand silk thread passes through these overlapping first rubber rings 3 or second rubber rings 4 in a wavy shape, extending to the entire edge of the film layer 1. Then, the two ends of the silk thread are respectively wound around adjacent first rubber rings 3 or second rubber rings 4 and tied tightly. Or, the edges of adjacent film layers 1 are aligned. A single-strand silk thread passes through the first rubber rings 3 or second rubber rings 4 alternately in a wavy shape, and then the two ends of the silk thread are respectively tied tightly. Two adjacent film layers 1 can be tied tightly to complete the splicing. The thickness increase at the splicing place is not obvious when tied tightly with a silk thread, and there is a gap between adjacent first rubber rings 3 or second rubber rings 4, which is conducive to smooth bending at the splicing place. After splicing, a large bubble film is formed, which can tightly wrap items of different sizes.

[0023] Among them, the size of the length of the second rubber ring 4 and the size of the length of the first rubber ring 3 are both not greater than twice the size of the thickness of the film layer 1. Compared with the traditional relatively thick magic tape, it can save space occupied during the splicing of the bubble film. It is convenient to pass two or more strands of silk thread through the first rubber ring 3 or the second rubber ring 4 in a figure-eight cross shape, and the tying effect is better, which is beneficial to improving the firmness of the splicing place.

[0024] As Figure 1 and Figure 2 shown in the figure, on both sides of the film layer 1 at the positions outside the two groups of first rubber rings 3, first rubber sheets 5 are also fixed. The first rubber sheets 5 can be made of silica gel material. The first rubber sheets 5 are all penetrated by adjacent first rubber rings 3. There is a gap between the first rubber sheets 5 and the adjacent bubble bags 2. The thickness of the first rubber sheets 5 is less than 0.2 mm. Tightening can be carried out by bonding between each first rubber ring 3, and the two edges of the film layer 1 are structurally strengthened, reducing the occurrence of cracking.

[0025] As Figure 1 and Figure 3 shown in the figure, on both sides of the film layer 1 at the positions outside the two groups of second rubber rings 4, second rubber sheets 6 are also fixed. The second rubber sheets 6 can be made of silica gel material. The second rubber sheets 6 are all penetrated by adjacent second rubber rings 4. There is a gap between the second rubber sheets 6 and the adjacent bubble bags 2. The thickness of the second rubber sheets 6 is less than 0.2 mm. Tightening can be carried out by bonding between each second rubber ring 4, and the other two edges of the film layer 1 are structurally strengthened, reducing the occurrence of cracking.

[0026] As Figure 1 and Figure 4 shown, at least one glass nylon thread 7 is inserted between each group of first rubber rings 3. The glass nylon thread 7 that is close to a transparent color is wound around each first rubber ring 3 or second rubber ring 4, without obvious color difference, which is convenient for the appearance of the formed bubble film after splicing to maintain color consistency. Especially as the outer packaging of items, it is convenient to maintain good aesthetics.

[0027] As Figure 1 and Figure 4 shown, a ring-shaped part 8 is fixed at one end of the glass nylon thread 7. The outer diameter of the ring-shaped part 8 is larger than the inner diameters of the first rubber ring 3 and the second rubber ring 4. The ring-shaped part 8 is used to limit one end of the glass nylon thread 7 to prevent the entire glass nylon thread 7 from detaching from the first rubber ring 3 or the second rubber ring 4. In this way, only the other end of the glass nylon thread 7 needs to be knotted, and the operation is more convenient.

[0028] As Figure 1 、 Figure 2 and Figure 3 shown, the outer edges of the first rubber ring 3 and the second rubber ring 4 both have rounded corners, which can contact the glass nylon thread 7 or silk thread with an arc surface, reducing the cutting effect during mutual friction and reducing the occurrence of the glass nylon thread 7 or silk thread being cut off.

[0029] The working principle of the present utility model is as follows: When packaging items, several film layers 1 are taken, and the first rubber rings 3 at the edges of each other overlap or the second rubber rings 4 overlap. A single-strand silk thread is passed through these overlapping first rubber rings 3 or second rubber rings 4 in a wavy shape, extending to the entire edge of the film layer 1. Then, the two ends of the silk thread are respectively wound around adjacent first rubber rings 3 or second rubber rings 4 and knotted tightly. Or, the edges of adjacent film layers 1 are aligned, and a single-strand silk thread is alternately passed through the first rubber rings 3 or second rubber rings 4 in a wavy shape, and then the two ends of the silk thread are respectively knotted tightly, which can tie two adjacent film layers 1 to complete splicing. The thickness increase at the splicing part tied with the silk thread is not obvious, and there is a gap between adjacent first rubber rings 3 or second rubber rings 4, which is beneficial to the smooth bending at the splicing part. After splicing, a large bubble film is formed, which can tightly wrap items of different sizes.

[0030] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special instructions and limitations.
