In our daily life, the use of paper trays is indispensable for everyone. Generally speaking, the paper support products are mainly produced by using waste paper that we do not need as raw materials at all, and then pulping and adding some pulping materials from time to time, and then responding to molding, drying, and shaping processes. An environmentally friendly paper-plastic finished product manufactured. Because paper is a softer substance, the paper support product made from it is a very small and often imaginary packaging material used for lining cushioning. It has good shock resistance. , Moisture-proof and anti-static and many other functions. So what are the common types of paper trays?
What are the common types of paper trays:
1. Borderless structure
Edge refers to the structural component between the outer edge of the structure and the side wall surface of the structure on the surface parallel to the working surface of the environmental protection paper support structure and the forming template. The edge size refers to the width value of the structural component. In the non-edge paper mold structure, the actual size of the small edge is less than 2mm. The side buffering effect of no edge is mainly used for selection and processing from the whole. The lateral wall surface of the peripheral structure can be inclined or perpendicular to the load direction, and this angle can be adjusted to obtain the required cushioning effect.
2. Small edge structure
In the small-edge eco-friendly paper tray structure, the edge size is usually 8-15mm. The force and cushioning effect of the small edge structure in the edge direction is related to the edge length and the deformable space. It is mostly used for fixing and cushioning in the bearing mode, and is suitable for the application conditions of light weight of the package.
3. Flip edge structure
In the form of the environmental protection paper support of the flip structure, the edge structure is extended to the outside and forms a skirt outward, so that the environmental protection paper support structure forms a relatively complete outer side wall in appearance. Generally, in order to make the product to be packaged contact the mesh side of the paper tray to ensure the accuracy of packaging and fixing dimensions, and at the same time to make the smoother mesh side appear on the outer surface, it is ideal to use the flipping structure.
4, heavy load structure
The environmental protection paper support in the form of heavy load structure is mainly used for bearing load. The paper support mold structure of this structure can obtain the bearing capacity of the structure and the required overall rigidity by increasing the thickness of the mold body, or by increasing the arrangement density of the sides of the mold body. Heavy-duty structural paper trays are more than collective packaging in heavy-duty product packaging and transportation packaging.
5. Chamber structure and combined structure
The paper holder of the 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 opening container in structure. The paper tray of the cavity structure needs to use special molding equipment and technology to complete its production and processing. This kind of paper tray is mostly used as a container or decoration.
The above content is an introduction to the common types of paper trays. Paper tray products have a wide range of applications. The products that use foam as the lining can basically be replaced by paper tray products. Paper tray products have good anti-static properties, which play a better role in protecting electronic products and home appliances. Paper tray products can be stacked and stored, which is 1/2~2/5 smaller than the storage space occupied by foamed plastics. The freight and storage costs are small. The paper tray products have good water and gas permeability, so as to achieve the anti-corrosion effect. It can be widely used in the food packaging market.
