Paper tray, environmentally friendly paper tray has the functions of packaging, top fixing, buffering, decoration and other packaging functions of products. After the material composition and production process method are determined, the change of the structure method is the basis to ensure the performance of these packaging. Structural methods and their modifications are an important factor in making the package have the functions of compressive strength, elastic recovery, resistance to external force impact, and absorption of vibration energy.
The environmentally friendly paper tray has the functions of packaging, top fixing, buffering, decoration and other packaging functions of the product. After the raw material composition and production process are determined, the change of the structure form is the basis to ensure the performance of these packagings. Structural form and its changes are an important factor for the packaging to have compressive strength, elastic recovery, resistance to external force impact, and absorption of vibration energy.
The structure of paper support and environmental protection paper support is mainly distinguished from the edge structure. The edge structure of paper support and environmental protection paper support includes borderless structure, flanging structure and double edge structure.
The edgeless structure is suitable for disposable tableware and some industrial inner packaging products that are light in weight and not required for strength. The flanging structure and the double edge structure are mostly suitable for industrial inner packaging products, which can improve the overall strength, cushioning performance and beautification of the paper tray. The effect of product appearance. In addition, the chamber structure and the combined structure can meet certain application requirements, and the heavy-duty structure is more than the packaging and transportation packaging of heavy-duty products.
1. Eco-friendly paper holder: small edge structure paper holder
In the small edge paper support structure, the edge size is usually 8-15mm. The force and buffering effect of the small edge structure in the edge direction is related to the length of the edge and the deformable space. It is mostly used for fixing and buffering in the storage mode, and is suitable for the application conditions of light weight of the packaged object. The buffering effect of the structure is through the edges and side walls of the paper molding product when the structure of the paper molding product is in the form of a packaging product. The top surface of the product is usually flush with the open end surface of the paper mold packaging structure or slightly lower than the upper end surface. , and its structure is shown in Figure 6-3. This type of packaging is widely used in the combined packaging of complete sets of products, and the size of the paper tray is relatively small. An example of its application is shown in Figure 6-4. When used as a buffer pad in the buffer packaging of larger products, the paper tray with a small edge structure is mostly used in the packaging method of upper top and lower bottom, and attention is paid to the protection of external forces in the vertical direction. The application example is shown in the figure shown in 6-5
2. Environmental protection paper holder: Flip along the structural paper holder
In the form of the paper support of the flip-up structure, the edge structure is extended to the outside to form a skirt eversion, so that the paper support structure forms a relatively complete outer side wall in appearance. Usually, in order to make the packaged product come into contact with the mesh side of the paper holder to ensure the accuracy of packaging and fixing the size, and at the same time to make the flatter mesh side appear on the outer surface, it is ideal to use the flip-up structure. The structure is shown in Figure 6-6.
The load-bearing and deformation of the paper support in the edge direction is not only related to the edge Chengdu and the deformable space, but also closely related to the change of the lateral structure in the flip structure. The change of the lateral structure of the flip determines the structure form. In terms of lateral bearing and cushioning properties, especially the lateral structure has many optional variations, it has great flexibility to adjust the cushioning performance in this direction, and provides convenience for cushioning design.
Although the paper tray of the flip structure pays attention to packaging performance and overall aesthetics, it will increase some complexity in structural design and mold processing, especially when the internal size of the packaging box has been limited, the structure of the paper tray buffers the effective size It will be limited on the surface parallel to the working surface due to the turning structure, and will increase the complexity of the mesh laying and increase the installation size of the mold on the working formwork.
In the form of the flange structure, the flange size can be a part of the height of the mold body, or it can be the same as the height of the mold body, see Figure 6-6 (a), (b). The height of the turning edge is related to the structural characteristics of the packaged product, the product quality, the form of the paper pallet buffer packaging and the total height of the paper pallet structure. Figure 6-7 shows an example of the application of the edge structure.
3. Eco-friendly paper holder: no edge structure paper holder
The edge refers to the structural component between the outermost periphery of the structure body and the side wall surface of the structure body on the surface of the paper support model structure parallel to the working surface of the forming template. The edge dimension refers to the width value of the structural component. In the edgeless paper mold structure, the actual minimum edge size is less than 2mm.
The buffering effect of no edge in the lateral direction is mainly used for selection and processing from the whole. The lateral walls of the perimeter structure can be inclined or perpendicular to the load direction, and can be adjusted to obtain the required cushioning effect through this angle. The paper tray buffer packaging liner with no edge structure is mainly used in the buffer packaging of the two ends of the packaged product, and most of the packaging forms are in a symmetrical structure. The application example is shown in Figure 6-2. This structure form It is convenient for the product to be placed during the packaging operation and to be taken out during consumption. The edgeless structure can effectively control the impact of structural changes on the buffering effect, and reduce the local deformation caused by the deformation of the edge and the failure of the product to be fixed in the package. The paper support in the form of an edgeless structure is convenient for the processing and assembly of the paper mold.
4. Eco-friendly paper holder: heavy-duty structural paper holder
The paper holder in the form of heavy load structure is mainly used to bear the load. The paper pallet structure of this structure can obtain the bearing capacity of the structure and the required overall rigidity by either increasing the thickness of the mold or increasing the density of the side edges of the mold. The heavy-duty structural paper tray is more than the collective packaging in the packaging and transportation packaging of heavy products.
5. Environmental protection paper holder: chamber structure and combined structure paper holder
The paper holder in the form of a cavity structure is produced and processed by a combined mold, and the paper holder is a certain form of closed cavity or formed into a small open container in structure. The paper holder in the form of the cavity structure needs to use special molding equipment and technology to complete its production and processing: this paper holder is mostly used as a container or decoration,
