Description

Technical Field

[0001] This disclosure relates to the field of packaging technology, and in particular to a cushioning device and packaging structure. Background Technology

[0002] Electrical appliances are generally sensitive to impacts and vibrations. During distribution, they are typically packaged for transport and storage. To protect them from mechanical loads like impacts and vibrations, cushioning devices are usually installed within the packaging. Traditional cushioning devices are generally made of foam materials such as expanded polyethylene (PE). However, PE is difficult to degrade in nature and easily pollutes the environment. Summary of the Invention

[0003] To address the aforementioned technical problems, this disclosure provides a cushioning device and packaging structure.

[0004] The first aspect of this disclosure provides a cushioning device, comprising: a base box, a cushioning element, and a support element, each folded from corrugated cardboard;

[0005] The bottom box has a cavity;

[0006] The buffer member forms a buffer cavity, the buffer member is disposed in the cavity and connected to the bottom box, the cavity is used to accommodate the product to be packaged and to make the buffer member abut against the product;

[0007] The support member is connected to the buffer member, with a portion of the support member embedded in the buffer cavity and a portion of the support member disposed between the buffer member and the bottom box.

[0008] In the above process, the bottom box, cushioning components, and supporting components can all be assembled through cutting, folding, and other processes. Corrugated cardboard has good processing performance and is easy to handle. Before packaging, the corrugated cardboard can be fully stacked together, occupying less storage and transportation space and saving logistics costs. When needed, the bottom box, cushioning components, and supporting components can be folded separately and then assembled together, making it convenient and quick to use.

[0009] Furthermore, the bottom box includes a first plate and a second plate;

[0010] The first plate includes a first base plate and a first connecting plate connected to both sides of the first base plate;

[0011] The second plate includes a second base plate and a second connecting plate connected to both sides of the second base plate;

[0012] The first connecting plate is provided with a first bayonet, the first base plate is provided with a connecting hole, the connecting hole communicates with the first bayonet, and the second connecting plate is provided with a second bayonet;

[0013] The first base plate and the second base plate are stacked together, the connecting hole is sleeved on the second connecting plate, the first latch is engaged with the second connecting plate, and the second latch is engaged with the first connecting plate.

[0014] In the above process, after the first base plate and the second base plate are stacked, the bottom of the box is the overlapping part of two corrugated cardboard, which improves the strength and stability of the box and transforms the horizontal pressure on the box into vertical support force, thereby maintaining the stability of the overall structure.

[0015] Furthermore, at least one of the first connecting plate and the second connecting plate includes a first folding plate and a second folding plate, the first folding plate being connected to the first base plate, and the second folding plate being folded toward the first folding plate to form a double-layer plate.

[0016] In the above process, folding the bottom box creates a double-layer board structure on all side walls, giving the first and second connecting plates strong compressive strength, enhancing the cushioning strength of the bottom box in four directions, and improving the strength and stability of the bottom box. The four side walls forming the bottom box cavity are all two-layer corrugated cardboard structures, improving the strength and stability of the box and transforming the horizontal pressure on the bottom box into vertical support force, thus maintaining the overall structural stability.

[0017] Furthermore, the buffer includes a first support plate, a second support plate, and a third support plate connected in sequence;

[0018] The first support plate and the third support plate are disposed opposite to each other, and the third support plate is used to abut against the product;

[0019] The edge of the first support plate is provided with a third bayonet and a fourth bayonet;

[0020] The side of the support member is provided with a slot, which is engaged with the third slot and the fourth slot respectively so that one end of the support member abuts against the third support plate and the other end abuts against the bottom of the cavity.

[0021] In the above implementation process, the support component ensures good load-bearing capacity of the cushioning device, guaranteeing both cushioning quality and increasing its strength. The support component allows the cushioning device to fully meet the requirements of cushioning and drop tests, ensuring product safety. The support component contacts the inner wall of the base cavity to fix the entire cushioning device to the product, achieving the purpose of cushioning.

[0022] Furthermore, the support member includes a first side plate, a second side plate, a third side plate, and a fourth side plate connected in sequence;

[0023] The first side plate and the fourth side plate are stacked to form a triangular structure around the support member.

[0024] In the above implementation process, the triangle has high stability. When the support components are arranged in a triangle, the load-bearing capacity of the buffer device is better, ensuring both the quality of the buffer and the strength of the buffer device. When the product is placed in the cavity of the bottom box, it can fully meet the requirements of buffering and drop tests, and can fully guarantee the safety of the product.

[0025] Furthermore, the card slot includes a first slot and a second slot that are connected. The first slot is disposed in one of the second side plate and the third side plate, and the second slot is disposed in the first side plate and the fourth side plate. One of the first slot and the second slot is inserted into the third slot, and the other of the first slot and the second slot is inserted into the fourth slot.

[0026] In the above implementation process, the supporting components can be unfolded before packaging, allowing them to be fully stacked, thus occupying less storage and transportation space and saving logistics costs. When needed, the bottom box, cushioning components, and supporting components can be folded separately and assembled together, making them convenient to use and quick to assemble.

[0027] Furthermore, the third support plate is provided with a cut.

[0028] In the above implementation process, the cut can be formed by cutting. The cut can communicate with the buffer cavity, so that there is enough space inside the buffer cavity to place structural components such as pulleys. Therefore, this solution can meet the needs of products with protruding structures such as pulleys at the bottom, and improve the stability of product packaging.

[0029] Furthermore, the first support plate is provided with through holes;

[0030] The bottom of the cavity is provided with a honeycomb plate, one end of which is connected to the bottom of the cavity, and the other end passes through the through hole and abuts against the third support plate.

[0031] In the above process, honeycomb cardboard is freely added to the bottom of the cavity to enhance its compression resistance. After drop testing, the packaging can meet the physical performance requirements of the product.

[0032] Furthermore, the third support plate is provided with an extension plate, and the side wall of the bottom box is provided with an insertion hole, the extension plate being inserted into the insertion hole.

[0033] In the above implementation process, the buffer and the bottom box can be connected together, which is convenient to use and quick to assemble, and is conducive to mass production.

[0034] Furthermore, the number of the support members is set to four, and the four support members are arranged in a rectangular shape on the buffer member.

[0035] In the above implementation process, the core of the buffer device is four right-angled triangles, which can leave enough space inside to place structural components such as pulleys. Therefore, this solution can meet the needs of products with protruding structures such as pulleys at the bottom.

[0036] A second aspect of this disclosure provides a packaging structure including the cushioning device described in the first aspect.

[0051] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0052] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0053] The cushioning device 6 provided in this embodiment comprises a base box 1, a cushioning element 2, and a support element 3, all folded from corrugated cardboard. Compared to traditional foam materials, corrugated cardboard has the advantages of being easily recyclable, renewable, and environmentally friendly. It is also cheaper than foam materials. Since the base box 1, cushioning element 2, and support element 3 are all folded from corrugated cardboard, there is no need for the mold-making process required for traditional foam materials, saving on mold-making costs, reducing production time, and shortening the manufacturing cycle. Corrugated cardboard is not only strong but also has good toughness, thus providing better cushioning protection for the packaged product 5 and improving shock absorption.

[0054] The base box 1, buffer 2, and support 3 can all be integrally molded, making the production of the base box 1, buffer 2, and support 3 simpler and faster, which is conducive to mass production.

[0055] Existing pure paper packaging often fails to maintain stability under clamping conditions, and its operation is complex, resulting in low production efficiency. For medium to large electrical products (10kg-20kg), packaging costs are generally high. To address these issues, this solution utilizes the directional properties of corrugated cardboard, ensuring structural stability while protecting the product. The corrugated cardboard used in this solution is folded into an integrated cushioning device, allowing for pre-preparation and direct use on the production line, effectively guaranteeing production efficiency. Furthermore, this solution primarily uses corrugated cardboard, and through its design utilizing the cardboard's directional properties and incorporating support components on the bottom, it offers higher compression and impact resistance than ordinary cardboard packaging. It can also be shaped according to the product's structure, making it more versatile. The overall design is environmentally friendly pure paper packaging at a lower cost.

[0056] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the bottom box 1 forms a cavity 14 with an opening at one end; the cushioning member 2 forms a cushioning cavity 24, and the cushioning member 2 is disposed in the cavity 14. The cavity 14 is used to accommodate the product 5 to be packaged and to allow the cushioning member 2 to abut against the product 5. The cushioning member 2 is connected to the bottom box 1. The cushioning member 2 can be snapped, inserted, or glued to the bottom box 1. In use, the product 5 is placed in the cavity 14, and the product 5 abuts against the cushioning member 2; the support member 3 is connected to the cushioning member 2. Part of the support member 3 is embedded in the cushioning cavity 24; part of the support member 3 is disposed between the cushioning member 2 and the bottom box 1. The support member 3 provides good load-bearing capacity for the cushioning device 6, ensuring both cushioning quality and increasing the strength of the cushioning device 6. The ingenious structural design maximizes the use of corrugated cardboard and simplifies the processing procedure. By folding and splicing the support member 3, the cushioning device 6, and the bottom box 1 from corrugated cardboard and assembling them together, the product 5 can be well protected.

[0057] The bottom box 1, buffer component 2, and support component 3 of the cushioning device 6 provided in this embodiment can all be assembled after cutting, folding, and other processes. Furthermore, corrugated cardboard has good processing performance and is easy to operate. Before packaging, the corrugated cardboard can be fully stacked together, occupying less storage and transportation space and saving logistics costs. When needed, the bottom box 1, buffer component 2, and support component 3 can be folded and assembled together, making it convenient to use and quick to assemble.

[0058] Combination Figure 8 and Figure 9 As shown, the bottom box 1 includes a first board 11 and a second board 12, which are two independent corrugated cardboard pieces.

[0059] The first plate 11 includes a first base plate 111 and a first connecting plate 112, with the first connecting plate 112 connected to both sides of the first base plate 111. A crease 4 exists between the first base plate 111 and the first connecting plate 112. During assembly, the first connecting plate 112 can be folded along the crease 4 towards the first base plate 111, making assembly faster.

[0060] The second plate 12 includes a second base plate 121 and a second connecting plate 122, with the second connecting plate 122 connected to both sides of the second base plate 121. A crease 4 is present between the second base plate 121 and the second connecting plate 122. During assembly, the second connecting plate 122 can be folded along the crease 4 towards the second base plate 121, making assembly faster.

[0061] The first connecting plate 112 is provided with a first bayonet 112a, which can be formed by cutting. The first base plate 111 is provided with a connecting hole 111a, which can be formed by cutting. The connecting hole 111a communicates with the first bayonet 112a. The second connecting plate 122 is provided with a second bayonet 122a, which can be formed by cutting.

[0062] The first base plate 111 and the second base plate 121 are stacked together. The connecting hole 111a is fitted onto the second connecting plate 122. The first latch 112a is engaged with the second connecting plate 122, and the second latch 122a is engaged with the first connecting plate 112. That is, the first plate 11 and the second plate 12 are folded and assembled together, which is convenient to use and quick to assemble, and is conducive to mass production.

[0063] After the first base plate 111 and the second base plate 121 are stacked, the bottom of the bottom box 1 is the overlapping part of two corrugated cardboard, which improves the strength and stability of the bottom box 1 and transforms the horizontal relative pressure borne by the bottom box 1 into the vertical support force, thereby maintaining the stability of the overall structure.

[0064] Specifically, the first base plate 111 can be positioned above the second base plate 121, that is, the first base plate 111 forms the bottom wall facing the cavity 14.

[0065] In some specific embodiments, at least one of the first connecting plate 112 and the second connecting plate 122 includes a first folding plate 15 and a second folding plate 16, the first folding plate 15 being connected to the first base plate 111, and the second folding plate 16 being folded toward the first folding plate 15 to form a double-layer plate.

[0066] Optionally, the first connecting plate 112 includes a first folding plate 15 and a second folding plate 16. A crease 4 is provided between the first folding plate 15 and the second folding plate 16. When folding, the first folding plate 15 can be folded along the crease 4 toward the second folding plate 16. After folding, the side wall of the bottom box 1 forms a double-layer plate structure, which makes the first connecting plate 112 have strong pressure resistance, can enhance the horizontal buffer strength, and improve the strength and stability of the bottom box 1.

[0067] Optionally, the second connecting plate 122 includes a first folding plate 15 and a second folding plate 16. A crease 4 is provided between the first folding plate 15 and the second folding plate 16. When folding, the first folding plate 15 can be folded along the crease 4 toward the second folding plate 16. After folding, the side wall of the bottom box 1 forms a double-layer plate structure, which makes the second connecting plate 122 have strong pressure resistance, can enhance the horizontal buffer strength, and improve the strength and stability of the bottom box 1.

[0068] Optionally, both the first connecting plate 112 and the second connecting plate 122 include a first folding plate 15 and a second folding plate 16. A crease 4 is provided between the first folding plate 15 and the second folding plate 16. During folding, the first folding plate 15 can be folded along the crease 4 towards the second folding plate 16. After folding, the side walls of the bottom box 1 form a double-layer board structure, giving the first connecting plate 112 and the second connecting plate 122 strong compressive strength, enhancing the cushioning strength of the bottom box 1 in four directions, and improving the strength and stability of the bottom box 1. The four side walls forming the cavity 14 of the bottom box 1 are all two-layer corrugated cardboard structures, improving the strength and stability of the box, and transforming the horizontal relative pressure borne by the bottom box 1 into a vertical supporting force, thereby maintaining the overall structural stability.

[0069] Combination Figure 3 and Figure 4 As shown, the buffer 2 includes a first support plate 21, a second support plate 22, and a third support plate 23 connected in sequence. A crease 4 exists between the first support plate 21 and the second support plate 22 to facilitate quicker assembly. A crease 4 also exists between the second support plate 22 and the third support plate 23 to facilitate quicker assembly. Both the first support plate 21 and the third support plate 23 are folded towards the second support plate 22, forming a U-shaped structure between them.

[0070] The first support plate 21 and the third support plate 23 are arranged opposite to each other. The third support plate 23 is used to abut against the product 5. Optionally, the first support plate 21 and the third support plate 23 are parallel. Optionally, both the first support plate 21 and the third support plate 23 are flat. Optionally, the third support plate 23 is inclined relative to the first support plate 21. Optionally, the third support plate 23 is an arc-shaped plate. By changing the degree of inclination or curvature of the third support plate 23, the third support plate 23 can be better adapted to the product 5 to be installed, making the applicability of the buffer device 6 stronger.

[0071] The edge of the first support plate 21 is provided with a third latch 211 and a fourth latch 212. The third latch 211 and the fourth latch 212 can be formed by cutting, which is simple and efficient. The side of the support member 3 is provided with a slot, which can also be formed by cutting, which is simple and efficient. The slot engages with the third latch 211 and the fourth latch 212 respectively, so that one end of the support member 3 abuts against the third support plate 23 and the other end abuts against the bottom of the cavity 14. Specifically, one end of the support member 3 abuts against the third support plate 23 and the other end abuts against the first bottom plate 111. The support member 3 provides good load-bearing capacity for the buffer device 6, ensuring both buffering quality and increasing the strength of the buffer device 6. The support member 3 enables the buffer device 6 to fully meet the requirements of buffering and drop testing, and can fully guarantee the safety of the product 5. The support member 3 can contact the inner wall of the cavity 14 of the bottom box 1 to fix the entire buffer device 6 to the product 5 and achieve the purpose of buffering.

[0072] Combination Figure 5 , Figure 6 and Figure 7 As shown, the support component 3 includes a first side plate 31, a second side plate 32, a third side plate 33, and a fourth side plate 34 connected in sequence. The first side plate 31 and the support component 3 can be assembled after cutting, folding, and other processes, offering the advantage of convenient operation. A crease 4 is provided between the first side plate 31 and the second side plate 32. A crease 4 is also provided between the second side plate 32 and the third side plate 33, and between the third side plate 33 and the fourth side plate 34. Before assembly, the first side plate 31, the second side plate 32, the third side plate 33, and the fourth side plate 34 can be folded along the creases 4 respectively, making the assembly of the support component 3 faster. Before packaging, the support component 3 can be laid flat or unfolded, and multiple support components 3 can be stacked together, occupying less storage and transportation space and saving logistics costs. When needed, the first side plate 31, the second side plate 32, the third side plate 33, and the fourth side plate 34 can be folded along the creases 4 respectively and then assembled together, making it convenient to use and quick to assemble.

[0073] The first side plate 31 and the fourth side plate 34 are stacked to form a triangular structure around the support member 3. The stacked first side plate 31 and the fourth side plate 34 can be connected by adhesive. Triangles have high stability; when the support member 3 is arranged in a triangle, the load-bearing capacity of the buffer device 6 is improved, ensuring both buffering quality and strength. When the product 5 is placed in the cavity 14 of the base box 1, it fully meets the requirements for buffering and drop tests, ensuring the safety of the product 5.

[0074] Optionally, one of the second side plate 32 and the third side plate 33 can contact the inner wall of the cavity 14 of the bottom box 1 to fix the entire cushioning device 6 to the product 5 and achieve the purpose of cushioning.

[0075] In some specific embodiments, the slot includes a first slot 331 and a second slot 341 that are connected. The first slot 331 is disposed in one of the second side plate 32 and the third side plate 33. The second slot 341 is disposed in the first side plate 31 and the fourth side plate 34. One of the first slot 331 and the second slot 341 is inserted into the third latch 211, and the other of the first slot 331 and the second slot 341 is inserted into the fourth latch 212. That is, the support member 3 can be assembled after cutting, folding and other processes, and the corrugated cardboard has good processing performance and is easy to operate. Before packaging, the support member 3 can be in an unfolded state and can be fully stacked together, occupying less storage and transportation space and saving logistics costs. When needed, the bottom box 1, the cushioning member 2 and the support member 3 can be folded and assembled together, which is convenient to use and quick to assemble.

[0076] In some specific embodiments, the third support plate 23 is provided with a cut 231. The cut 231 can be formed by cutting. The cut 231 can communicate with the buffer cavity 24, so that the interior of the buffer cavity 24 can leave enough space to place structural components such as pulleys. Therefore, this solution can meet the needs of products 5 with protruding structures such as pulleys at the bottom, and improve the stability of the packaging of product 5.

[0077] Optionally, the position of the cut 231 corresponds to the position of the support member 3. Optionally, the cut 231 can connect to the cavity enclosed by the support member 3. The triangular support member 3 has a lot of internal space, and a cavity can be opened to place the pulley. The position of the cut 231 corresponding to the position of the triangular support member 3 can reduce the impact of the cut 231 on the load-bearing capacity of the buffer device 6, so that the load-bearing capacity of the buffer device 6 is better and the buffering quality is guaranteed.

[0078] Optionally, the part of the third support plate 23 that contacts the pulley uses a cutout 231 with a semi-open window structure. The corrugated cardboard with a semi-open window can reduce the shaking of the pulley during transportation.

[0079] In some specific embodiments, the first support plate 21 is provided with a through hole 213, and the bottom of the cavity 14 is provided with a honeycomb plate 111b. One end of the honeycomb plate 111b is connected to the bottom of the cavity 14, and the other end passes through the through hole 213 and abuts against the third support plate 23. Optionally, one end of the honeycomb plate 111b is connected to the first bottom plate 111, and the other end of the honeycomb plate 111b passes through the through hole 213 and abuts against the third support plate 23. The support members 3 are assembled into one piece by means of a snap-fit. Honeycomb cardboard can be freely added to the bottom of the cavity 14 to enhance the compression resistance according to the weight of the product 5. After drop testing, the packaging can meet the physical performance requirements of the product 5. Since the core of the cushioning device 6 is four right-angled triangles, its interior can leave enough space to place structural components such as pulleys. Therefore, this solution can meet the needs of products 5 with protruding structures such as pulleys at the bottom.

[0080] In some specific embodiments, the third support plate 23 is provided with an extension plate 232, and the side wall of the bottom box 1 is provided with an insertion hole 13. The extension plate 232 is inserted into the insertion hole 13, so that the buffer 2 and the bottom box 1 can be connected together, which is convenient to use, quick to assemble, and conducive to mass production.

[0081] In some specific embodiments, the number of support members 3 is set to four, and the four support members 3 are arranged in a rectangle on the buffer member 2. Optionally, the buffer device 6 can be formed by positioning the right-angled sides of the four right-angled triangular support members 3 at the four corners, with a honeycomb board 111b pasted in the middle, forming five-point support. Taking advantage of the high edge crush strength of corrugated paper, the support members 3 are made into triangular modules and assembled into a whole by inserting clips. Since the core of the buffer device 6 is four right-angled triangles, there is enough space inside to place structural components such as pulleys, so this solution can meet the needs of products 5 with protruding structures such as pulleys at the bottom.

[0082] like Figure 10 As shown, the packaging structure provided in this embodiment includes at least one cushioning device 6 provided in this embodiment.

[0083] Optionally, the packaging structure consists of a box and a cushioning device 6 installed in the box. When the product 5 is placed in the packaging structure and comes into contact with the cushioning device 6, it can fully meet the requirements of cushioning and drop testing, fully guarantee the safety of the product 5, and provide good protection for the product 5.

[0084] Optionally, the packaging structure includes a box body and two cushioning devices 6 installed inside the box body. The product 5 is placed between the two cushioning devices 6, which are respectively engaged or abutted against the two ends of the product 5, specifically the top and bottom of the product 5. Each cushioning device 6 consists of a bottom box 1 and the cushioning device 6. When the product 5 is clamped, the product 5 is subjected to the combined action of clamping force and its own weight in the front-to-back direction. The bottom box 1 can both resist pressure and prevent the packaging material from disintegrating and failing. The overall machine weight is approximately 13KG. Based on a drop height of 600mm, the bottom box 1 needs to be equipped with a cushioning component 2. Taking advantage of the high edge crush strength of corrugated paper, the support component 3 is made into a triangular module. The support component 3 is combined with the cushioning device 6 by inserting clips. Honeycomb cardboard can be freely added to the bottom to enhance the pressure resistance according to the weight of the product 5. The drop test shows that the packaging meets the physical performance requirements of the product 5. Optionally, the buffer device 6 is provided with four right-angled triangular support members 3, and the buffer cavity 24 can leave enough space to place structural components such as pulleys. Therefore, this solution can meet the needs of products 5 with protruding structures such as pulleys at the bottom.

[0085] All parts of this invention are made of corrugated cardboard through folding, cutting, and creasing processes. The low grammage of corrugated cardboard gives it excellent cushioning performance, compressive strength, and puncture strength. In addition, corrugated cardboard has good processing performance, is easy to operate, is easy to recycle, and is environmentally friendly. Before packaging, corrugated cardboard can be fully stacked together, occupying less storage and transportation space and saving logistics costs.

[0086] The cushioning device and packaging structure provided in this disclosure solve the structural stability problem of pure paper packaging under clamping conditions, and provide cushioning protection for products 5 weighing over 10KG with complex bottom structures. By adding a honeycomb plate 111b to the bottom of the cushioning device 6, the weight limit can be further increased. Tests showed that the packaged item remained securely in place under a clamping force of 1100kgf. A 13KG product 5 passed the IS standard drop test (one corner, three sides, six sides), followed by a drop from a height of 900mm on the bottom surface; the bottom cushioning device 6 did not fail, and the product 5 remained intact. This solution has relatively low requirements for the shape of the product 5; the top and bottom surfaces of the cushioning device 6 can be horizontal or inclined, meaning the third support plate 23 can be horizontal, inclined, or an arc surface of less than 15°. Its cost is approximately 2 / 3 of that of biodegradable plastic.

[0087] In summary, the cushioning device and packaging structure provided in this disclosure are suitable for current environmentally conscious applications. Traditional EPS packaging lacks suitable options for machines weighing over 10KG, and the cost of existing bio-based biodegradable materials remains high, making paper packaging a viable alternative. This solution solves the cushioning packaging problem for products 5 in this weight class (10KG~20KG) under clamping conditions, while being relatively independent of the product 5's shape, thus meeting the needs of most complete machine products 5. Specifically: 1. A specially structured corrugated cardboard base box 1 is used as the frame, ensuring overall structural stability under horizontal clamping and providing upward support to prevent the product 5 from falling; 2. A cushioning device 6 with good load-bearing capacity and a variable surface is developed as the cushioning component 2, ensuring cushioning quality and adapting well to products 5 with different shapes; 3. Both components are easily assembled and can be used together. Before packaging, they are assembled into a single unit, and the packaging operation is not significantly different from the EPS packaging solution, ensuring online efficiency. Corrugated cardboard packaging also allows for adjustments to material usage based on the characteristics of the product 5, further reducing costs.
