Design considerations for mailer boxes

The design of a mailer box depends on the type of equipment used, the production process, the type of paper made from different materials, and the type and nature of the product contained therein. Here are some considerations for the mailer box design.

This is the list of contents.

• Compressive strength of mailer box

• Correct mailer box size

Compressive strength of mailer box

The compressive strength of a mailer box is the maximum load and deformation that can be achieved by applying uniform dynamic pressure to the mailer box in a pressure testing machine until it breaks. The mailer box compressive testing process is divided into four stages. The first is the pre-loading stage, which ensures that the mailer box is in contact with the press platen. The second is the cross-press line is pressed under the table, and the deformation changes significantly when the load increases slightly. The third is the stage where the mailer box side wall is pressed, and the deformation increases slowly when the load increases more rapidly. The fourth is when the mailer box is destroyed, which is the collapse point of the mailer box.

Correction of mailer box size

1. Corrugated cardboard generally needs to be shaped so that it can bend well. This bending variation makes the extended size of the corrugated board the basic size of the corrugated box design. Therefore, the inside diameter size of the mailer box should be slightly shorter than the distance between the press line and the press line when the mailer box is unfolded. In practice, mailer boxes also have appropriate correction factors and additional dimensions, depending on the equipment used.

2. Mailer box is generally designed according to the inner diameter. Since the inner diameter size is easier to determine, it can be determined by physical measurement or a combination of group outer diameter size and reasonable arrangement to achieve. However, in practice, both the calculation of freight and the volume marked on the box surface is based on the outer diameter size. Therefore, in the mailer box design. Not only according to the inner diameter size to determine the manufacturing size, but also according to the manufacturing size to calculate the outside diameter size.

3. Also the tray or container’s inner diameter size determines the mailer box’s outer diameter size, so that the mailer box length, width, height, and transport mode adapt to achieve mechanized transport, and improve transport efficiency. Due to the different stacking methods of mailer boxes, the vertical projection area of the stacked objects should be adapted to the pallet size. If the size of the mailer box is calculated step by step from inside to outside, matching with the size of the box calculated step by step from outside to inside, the best size of the mailer box can be obtained. Of course, the best way is still from the outside to the inside, step by step.

In practice, customers often only provide us with the size or style of the internal product, which requires us to calculate the external dimensions and manufacturing dimensions of the mailing box. The calculation of the outside diameter of the mailing box is particularly important for products transported in mailing boxes. When measuring mailboxes, although the exact dimensions can be measured directly with a tool, indentation lines can lead to less accurate results. Especially, the measurement of the used mailbox size should be strictly calculated to ensure the accuracy of the size design and the smooth loading of the later pallets or containers to protect the goods. A good mailer box design can significantly save transportation costs.

To sum up, the design of mailer boxes is an important part of mailbox production. A competent mailer box product must be protected and in good shape. Especially for mailer boxes that have both sales packaging and shipping packaging functions, reasonable size, and compression resistance are the keys to mailer boxes. This is because our company takes great care in the production and design of mailer boxes.
