Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and particularly to a paper buffer packaging layer and packaging paper.

Background Art

[0002] With the rapid development of logistics, more and more wrapping papers and packaging bags are used for the packaging and transportation of articles. Most of the wrapping papers and packaging bags use bubble wrapping paper containing plastic. This bubble wrapping paper has excellent buffering and protection performance and can well protect the internal packages.

[0003] Wrapping paper is widely used in envelopes, packaging bags, etc., and it is necessary to provide excellent sealing performance and buffering effect. However, this conventional bubble wrapping paper containing plastic also has defects such as non-degradability, environmental pollution, and difficulty in recycling.

[0004] Currently, the bubble film packaging materials used in the market are all products made mainly from high-pressure polyethylene, and on top of that, auxiliary materials such as whitening agents and releasing agents are added and extruded at a high temperature of about 230 degrees to blow-mold into bubbles. The inside of the bubbles is filled with gas, and the stress is buffered by the bubbles to protect the product. It is widely used in shock-resistant buffer packaging for electronics, instruments, ceramics, handicrafts, household appliances, car dealerships, kitchens, furniture and lacquer products, glass products, and precision instruments. It can be made into products such as bubble bags and bubble kraft paper envelope bags. However, since the raw materials used in the production of bubble film are non-recyclable and non-degradable materials, it will also bring great pressure to environmental protection in China.

[0057] Note that the embodiments shown in the drawings are only examples for specifically and visually interpreting and explaining the concept of the present invention, and are not necessarily drawn to scale from the perspective of dimensional structure, nor do they constitute a limitation to the concept of the present invention.

[0058] The directional terms such as up, down, left, right, front, back, surface, back surface, top, bottom, etc., mentioned or that can be mentioned in this specification are relative concepts defined with respect to the structures shown in each drawing, and can be appropriately changed according to different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0059] Referring to FIGS. 1 to 4E of the drawings of the present specification, the paper buffer packaging layer according to the first preferred embodiment of the present application will be clarified in the following description. For the convenience of description in the present application, hereinafter, the paper buffer packaging layer will be referred to as the buffer packaging layer.

[0060] The buffer packaging layer includes a base layer 10 and a plurality of buffer bags 20 formed on the base layer 10. The buffer bag 20 and the base layer 10 have an integrated structure, and the buffer bag 20 is formed on one side of the base layer 10. In the preferred embodiment of the present application, the base layer 10 has a front surface 11 and a back surface 12. Here, the buffer bag 20 protrudes from the front surface 11 and / or the back surface 12 of the base layer 10. Since the buffer bag 20 protrudes from the base layer 10, it is understood that when the buffer packaging layer receives a lateral force, the buffer bag 20 deforms by receiving the force so that a buffering effect is formed.

[0061] In addition, in the preferred embodiment of the present application, the buffer packaging layer is made of paper material. Here, the buffer bag 20 of the buffer packaging layer is a buffer structure integrally formed on one side of the base layer 10 by stamping, extrusion or roller pressing. In the preferred embodiment of the present application, the buffer bag 20 of the buffer packaging layer preferably has a hemispherical foam structure. Here, the buffer bag 20 provides a buffering effect by the support of the base layer 10.

[0062] In the preferred embodiment of the present application, the buffer packaging layer is further provided with a plurality of air chambers 201. Here, the air chamber 201 is formed inside the buffer bag 20, and the inside of the air chamber 201 is filled with gas, or filled with other buffer materials such as sponge, or filled with gas. The air chamber 201 of the buffer packaging layer can support the buffer bag 20 of the buffer packaging layer, which is advantageous for improving the buffering and supporting effects of the buffer packaging layer.

[0063] As shown in FIGS. 1 to 4E, the base layer 10 of the buffer packaging layer is a paper structure. Here, the base layer 10 may be cardboard having a certain hardness or paper having a certain flexibility. The buffer bag 20 protrudes from the upper side and / or the lower side of the base layer 10, that is, the bottom end of the buffer bag 20 is connected to the base layer 10, and the top end protrudes from the front surface 11 and / or the back surface 12 of the base layer 10.

[0064] The buffer bag 20 of the buffer packaging layer includes a bottom portion 21 and a top portion 22 integrally extending outward from the bottom portion 21. The bottom portion 21 of the buffer bag 20 is connected to the base layer 10 and provides a supporting action to the buffer bag 20 through the base layer 10. The top portion 22 of the buffer bag 20 is located outside the bottom portion 21, and when the buffer packaging layer receives a force, the top portion 22 of the buffer bag 20 is deformed by the force so as to provide a supporting and buffering action. Since the buffer bag 20 protrudes from the base layer 10, it is understood that when the buffer packaging layer receives an external force, the top portion 22 of the buffer bag 20 is first affected by the force and deformed.

[0065] In the preferred embodiment of the present application, the buffer bag 20 preferably has a hemispherical shape. In another alternative embodiment of the present application, the buffer bag 20 has a cylindrical structure or a shape of a heart-shaped protrusion. Thus, in the present application, the shape of the buffer bag 20 is only used as an example here and is not limited. The bottom portion 21 of the buffer bag 20 integrally extends upward or downward from the base layer 10 to the top portion 22 of the buffer bag 20. In a preferred embodiment of the present application, the bottom portion 21 of the buffer bag 20 preferably extends vertically upward or downward from the base layer 10. When the top portion 22 of the buffer bag 20 receives a force, the bottom portion 21 of the buffer bag 20 conducts the force along the direction perpendicular to the base layer 10, which is advantageous for improving the supporting action of the buffer bag 20.

[0066] As shown in FIGS. 3A and 3B, at least one rib groove 23 is further provided in the buffer bag 20 of the buffer packaging layer. Here, at least one of the rib grooves 23 is formed on the surface of the buffer bag 20. By improving the strength of the buffer bag 20 by the rib grooves 23, the supporting action, torque, and buffering action of the buffer packaging layer when the buffer bag 20 receives force are improved.

[0067] The rib groove 23 is formed on the outer surface of the buffer bag 20 so as to be recessed inward from the outer surface of the buffer bag 20. In other words, the rib groove 23 is a groove structure formed in the buffer bag 20. The rib groove 23 is a groove structure formed by the outer surface of the buffer bag 20.

[0068] As shown in FIGS. 3A and 3B, in the preferred embodiment of the present application, the rib groove 23 further includes a weft rib groove 231. Here, the weft rib groove 231 is formed in the buffer bag 20 in an annular structure. The plane where the weft rib groove 231 is located is substantially parallel to the base layer 10. When the top 22 of the buffer bag 20 receives force, the weft rib groove 231 of the rib groove 23 will be deformed by the force so as to provide a buffering action. The rib groove 23 further includes a warp rib groove 232. The warp rib groove 232 is formed in the buffer bag 20 in a semi-annular structure. Here, the plane where the warp rib groove 232 is located is substantially perpendicular to the base layer 10. When the top 22 of the buffer bag 20 receives force, the warp rib groove 232 of the rib groove 23 provides a supporting action.

[0069] In the preferred embodiment of the present application, it is understood that the number of the rib grooves 23 may be singular or even. In the preferred embodiment of the present application, the warp rib grooves 232 of the rib groove 23 are preferably 3, 5, 7, etc. Here, the interval distances between the warp rib grooves 232 are equal. When the number of the warp rib grooves 232 of the rib groove 23 is 2, 4, 6, each of the warp rib grooves 232 is symmetrically formed on the outer surface of the buffer bag 20.

[0070] Specifically, the vertical yarn rib groove 232 extends from the bottom 21 of the buffer bag 20 to the top 22 of the buffer bag 20. Optionally, in another alternative embodiment of the present application, the length of the vertical yarn rib groove 232 is one-third or two-thirds of the length from the bottom 21 to the top 22 of the buffer bag 20.

[0071] The horizontal yarn rib groove 231 further includes at least two horizontal yarn rib walls 2311. Here, at least two of the horizontal yarn rib walls 2311 extend integrally from the buffer bag 20, and a groove body of the horizontal yarn rib groove 231 is formed between at least two horizontal yarn rib walls 231. In the preferred embodiment of the present application, the horizontal yarn rib walls 2311 of the horizontal yarn rib groove 231 overlap each other. When the buffer bag 20 receives a force, two adjacent horizontal yarn rib walls 2311 of the horizontal yarn rib groove 231 are separated by the force, thereby providing a buffering effect for the force.

[0072] The vertical yarn rib groove 232 further includes at least two vertical yarn rib walls 2321. A groove body structure of the vertical yarn rib groove 232 is formed between at least two of the vertical yarn rib walls 2321. At least two of the vertical yarn rib walls 2321 of the vertical yarn rib groove 232 are provided in the vertical direction along the buffer bag 20. When the top of the buffer bag 20 receives a force, at least two of the vertical yarn rib walls 2321 of the vertical yarn rib groove 232 provide a supporting force so that the supporting effect of the buffer bag is improved.

[0073] In the preferred embodiment of the present application, at least two of the horizontal yarn rib walls 2311 of the horizontal yarn rib groove 231 and at least two of the vertical yarn rib walls 2321 of the vertical yarn rib groove 232 extend from the outer surface of the buffer bag 20 to the inside so as to form a structure from the outside to the inside, which is understood to be advantageous for improving the structural characteristics of the buffer bag.

[0074] In addition, in the preferred embodiment of the present application, the horizontal yarn rib grooves 231 and the vertical yarn rib grooves 232 of the buffer bag 20 have a linear, curved or wavy structure. The shapes of the horizontal yarn rib grooves 231 and the vertical yarn rib grooves 232 are used only as an example here and are not limited.

[0075] As shown in FIGS. 4A to 4E, according to another aspect of the present application, the structure of the buffer packaging layer will be further described. Here, the buffer bags 20 of the buffer packaging layer are uniformly formed on the base layer 10. As shown in FIG. 4A, in the preferred embodiment of the present application, the buffer bags 20 of the buffer packaging layer have a uniform size. An intermediate space 202 is further provided in the buffer packaging layer. Here, the intermediate space 202 is formed on one side of the base layer 10 so as to be located outside each of the buffer bags 20. The intermediate space 202 of the buffer packaging layer is formed on the same side of the buffer bags 20, and it is understood that the intermediate space 202 is used to fill a buffer filling material so as to provide a better buffer effect. When the buffer packaging layer is sealed, gas can be filled so that gas storage chambers are formed in the intermediate space 202 of the buffer packaging layer and the air chambers 201 of the buffer bags 20 that are spaced apart from each other. When the buffer packaging layer receives a force, it is understood that the intermediate space 202 and the air chambers 201 of the buffer bags 20 provide a reverse force by pressure, which is advantageous for providing a gas buffer effect.

[0076] As shown in FIG. 4A, let the outer diameter of the bottom 21 of the buffer bag 20 be H1, and the distance between the bottoms 21 of two adjacent buffer bags 20 be H2. Here, H1 and H2 satisfy the condition of 0≧H1≧H2. That is, in order to improve the buffer effect of the buffer packaging layer, a plurality of the buffer bags 20 spaced apart from each other are arranged on one side of the base layer 10. And buffer bags 20 spaced apart from each other with good support and pressure resistance effect are provided.

[0077] As shown in FIG. 4B, in the preferred embodiment of the present application, the buffer bags 20 of the buffer packaging layer have different sizes (diameters). Specifically, in the preferred embodiment of the present application, the buffer bag 20 further includes a first buffer bag 20A and a second buffer bag 20B. Here, the bottom diameter of the first buffer bag 20A is larger than the bottom diameter of the second buffer bag 20B. In this way, when the two layers of the buffer bag layer are stacked one on top of the other, the first buffer bag 20A can be stacked above the second buffer bag 20B, and the second buffer bag 20B is provided inside the first buffer bag 20A. The first buffer bag 20A and the second buffer bag 20B of the buffer bag 20 provide a double buffer protection effect, and thus the buffer and support effects are improved.

[0078] As shown in FIG. 4C, in the preferred embodiment of the present application, different from the above-described first preferred embodiment, the outer diameter of the bottom 21 of the buffer bag 20 is defined as H1, and the distance between the bottoms 21 of two adjacent buffer bags 20 is defined as H2. Here, H1 and H2 are different in that they satisfy the condition of Hl ≦ H20. When the two buffer packaging layers are provided opposite to each other, the buffer bag 20 of one buffer packaging layer can be provided in alignment with the space 201 of the other buffer packaging layer. As a result, the two buffer packaging layers can be provided in alignment. It is understood that the two buffer packaging layers provided in alignment can provide buffer and support effects in two directions (from the front and back surfaces of the base layer 10).

[0079] As shown in FIGS. 4A to 4C, the buffer bag 20 is formed on one side of the base layer 10, that is, the buffer bag 20 is formed on the front surface or the back surface of the base layer 10. As shown in FIG. 4D, the buffer bag 20 is formed on both the front surface and the back surface of the base layer 10. Therefore, the buffer bag 20 further includes a front surface buffer bag 20C and a back surface buffer bag 20D. Here, the front surface buffer bag 20C is formed on the front surface 11 of the base layer 10, that is, the front surface buffer bag 20C protrudes upward from the front surface of the base layer 10 and extends. The back surface buffer bag 20D is formed on the back surface 12 of the base layer 10, that is, the back surface buffer bag 20D protrudes downward from the back surface of the base layer 10 and extends.

[0080] It is understood that the front surface buffer bag 20C located on the front surface of the base layer 10 can provide a buffering and supporting function from the base layer 10, and the back surface buffer bag 20D located on the back surface of the base layer 10 can provide a buffering and supporting function from the base layer 10.

[0081] In addition, in the preferred embodiment of the present application, the front surface buffer bag 20C and the back surface buffer bag 20D of the buffer bag 20 are spaced apart from each other and integrally extend from the base layer 10.

[0082] As shown in FIG. 4E, the buffer packaging layer in the above preferred embodiment is different in that the front surface buffer bag 20C of the buffer bag 20 integrally extends from the back surface buffer bag 20D, that is, the front surface buffer bag 20C and the back surface buffer bag 20D have an integrated structure.

[0083] As shown in FIGS. 5 to 8, the wrapping paper according to another preferred embodiment of the present application will be clarified in the following description. The wrapping paper includes an inner layer 100, an outer layer 200, and at least one packaging buffer layer 300 provided between the inner layer 100 and the outer layer 200. Here, the structure of the packaging buffer layer 300 is the same as that of the packaging buffer layer in any of the above preferred embodiments and will not be described here.

[0084] The packaging buffer layer 300 is located between the inner layer 100 and the outer layer 200. Here, the packaging buffer layer 300 is adhered to the inner side of the inner layer 100 and the outer layer 200 by adhesion. The top of the buffer bag 20 of the packaging buffer layer 300 is adhered to the inner side of the inner layer 100 or the inner side of the outer layer 200, and the gap space 202 of the packaging buffer layer 300 is sealed by the inner layer 100 or the outer layer 200, thereby forming a sealed gas storage structure. Thereby, the base layer 10 of the packaging buffer layer 300 is adhered to and sealed by the inner layer 100 or the outer layer 200, thereby forming a sealed gas storage structure.

[0085] When the packaging buffer layer 300 of the wrapping paper is multilayered, it is understood that a multiple buffer structure is formed by the packaging buffer layer 300. As shown in FIG. 6, in the preferred embodiment of the present application, the packaging buffer layer 300 of the wrapping paper further includes a first buffer layer 300a and a second buffer layer 300b. Here, the first buffer layer 300a and the second buffer layer 300b have the same structure and are provided in alignment. Here, the buffer bag 20 of the first buffer layer 300a corresponds to the gap space 202 of the second buffer layer 300b and is provided in the gap space 202 of the second buffer layer 300b. Here, the buffer bag 20 of the second buffer layer 300b corresponds to the gap space 202 of the first buffer layer 300a and is provided in the gap space 202 of the first buffer layer 300a.

[0086] The base layer 10a of the first buffer layer 300a and the base layer 10b of the second buffer layer 300b of the packaging buffer layer 300a are adhered between the inner layer 100 and the outer layer 200. In the preferred embodiment of the present application, it is understood that the two-layer packaging buffer layer 300 provides a buffering effect from the inner layer 100 and the outer layer 200.

[0087] As shown in FIG. 7, in the preferred embodiment of the present application, the packaging buffer layer 300 further includes an inner buffer layer 300c and an outer buffer layer 300d. Here, the size of the buffer bag 20c of the inner buffer layer 300c is smaller than the size of the buffer bag 20d of the outer buffer layer 300d. In this way, when the inner buffer layer 300c and the outer buffer layer 300d are provided in alignment, the buffer bag 20c of the inner buffer layer 300c is provided inside the outer buffer layer 20d.

[0089] In the preferred embodiment of the present application, the inner buffer layer 300c and the outer buffer layer 300d of the packaging buffer layer 300 are adhered to form a two-layer buffer structure. Here, the inner layer 100 is adhered to the base layer 10 of the inner buffer layer 300c, and the outer layer 200 is adhered to the top of the outer buffer layer 300d. Thereby, the packaging buffer layer 300 forms a two-layer air chamber structure, that is, an inner air chamber 101 is formed by the inner buffer layer 300c and the inner layer 100, and an outer air chamber 102 is formed by the inner buffer layer 300c and the outer buffer layer 300d. A double-air chamber buffer structure is formed by the inner air chamber 101 and the outer air chamber 102 of the packaging buffer layer 300.

[0090] In the preferred embodiment of the present application, it is understood that the inner air chamber 101 of the packaging buffer layer 300 is a sealed air chamber structure formed by the inner buffer layer 300c and the inner layer 100, and the outer air chamber 102 is a sealed structure formed by the inner buffer layer 300c and the outer buffer layer 300d.

[0091] When the side surface of the wrapping paper receives a force, the multi-layer support structure formed by the inner buffer layer 300c, the outer buffer layer 300d of the packaging buffer layer 300, and the inner air chamber 101 and the outer air chamber 102 formed in the packaging buffer layer 300 provides double support and a buffer structure for the wrapping paper, which is understood.

[0092] In the preferred embodiment of the present application, the wrapping paper is preferably a paper structure. Here, the inner layer 100 is a non-bubble paper such as kraft paper, which is advantageous for reducing friction and flattening the internal structure. The outer layer 200 is a paper structure such as kraft paper.

[0093] Referring to FIG. 8 of the drawings of the present specification, according to another aspect of the present application, a manufacturing method of the packaging buffer layer is provided.
