In production full paper bucket At that time, we considered the convenience of production and chose rectangular shapes in most cases. But sometimes, in order to reflect a certain concept of the packaged material or manufacturer, containers are often chosen with some more peculiar shapes.
When planning the shape, the external shape and material of the container should be determined based on the standards, weight, shape, and other conditions of the packaged material, and a three-dimensional rendering should be created to provide a basis for structural planning. It should be emphasized that 3D renderings have extremely important educational significance in packaging container planning. In many cases, people may not be able to fold what they need based solely on work drawings or box items paper box Therefore, before ending the planning, it is often necessary to create a three-dimensional rendering from scratch to highlight its structural features To teach people how to properly shape containers.
The unique and innovative design is in opposition to the economy of making bento boxes, and requires careful coordination. Generally speaking, regardless of the shape, a certain structure can be used to complete or approximate it, but when completing some shapes, the difficulty and cost of production may increase significantly. For most commercial packaging, the production volume is often large, so the economy should be the primary consideration when planning the appearance, and the embodiment of product concept can also be compensated by using performance planning.
flame retardantfull paper bucketThe following requirements should be met:
Firstly, Paper bucket production After flame retardant treatment, the raw paper used should have no significant changes in performance indicators such as mechanical strength, standard stability, and color. Has good weather resistance and durability; Once burned, the amount of smoke produced is minimal, and the corrosiveness and toxicity of the smoke are minimal;
Secondly, the process is simple, the price is reasonable, and it is suitable for implementation;
Thirdly, flame retardants should have a certain degree of water solubility and excellent thermal stability, and should not cause corrosion to equipment and papermaking machinery during the processing of paper products. The flame retardant performance should not decrease too much during the incineration process.
paperboard drum The strength largely depends on the deformation planning. In addition to being related to the selected raw materials, it is also related to the thickness of the paper drum and the magnitude of the axial force on the paper drum. Under the condition of material judgment and fixed circumference, the vertical compression strength of the paper drum should be greater than 8000N, the lateral compression strength should be greater than 4000N, and the puncture strength should be greater than 10N.
Effect onfull paper bucketThe greater the lateral pressure and the longer the circumference, the greater the deformation of the paper barrel; The high elastic modulus, number of layers, and thickness of paper drums result in minimal deformation. From this, it can be concluded that in order tofull paper bucketThe conclusion is that if the stress is low, the number of layers in the paper drum and the thickness of the cardboard should be increased. The higher the stiffness coefficient of the paper bucket, the greater the stiffness of the paper bucket. The material should be selected from cardboard with high elastic modulus, multiple layers of paper thickness, and a relatively small diameter structure.
full paper bucketThe deformation of the cardboard barrel is related to its stiffness, that is, whether the stiffness coefficient during planning is reasonable.full paper bucketThe size of the deformation is proportional to the lateral pressure and circumferential length of the paper tube, and is fibre drum The elastic modulus, thickness, and number of layers of the paper barrel are inversely proportional.
