Teach you how to improve the practicality of product packaging design

First, let's examine the load that these accessories experience during transportation. When a package is subjected to horizontal forces (X-direction), such as sudden braking, the internal items may move forward due to inertia. This can result in impacts against the front and rear walls of the accessory. Since corrugated cardboard has some cushioning properties, it helps reduce the damage caused by these impacts. Additionally, the internal components might rub against the side walls of the accessory or the top and bottom of the package. This friction can slow down or stop the movement of the contents, which also applies to vertical movements (Z-direction).

If the package is exposed to vertical vibrations or impacts (Y-direction), the internal items may move up and down, causing impacts on the top and bottom of the packaging box. Again, the cushioning properties of the top and bottom materials help absorb these shocks. The internal parts may also come into contact with the four walls of the accessory, further preventing or reducing their upward or downward movement.

Except for special cases, these accessories do not provide structural support to the entire package. Therefore, during stacking, they mainly serve to separate items rather than contribute significantly to the structural integrity of the package.

Now, let's consider the risk of damage to both the accessories and the packaging container during transit. Since these accessories fill most of the space inside the package, there is very little room for the contents to move. This minimizes the chances of the product coming into direct contact with the inner walls of the container. Due to the friction between the product and the accessory walls, any movement is restricted, reducing the likelihood of damage. Furthermore, the accessories are protected by the outer packaging, so under normal conditions, they are unlikely to be damaged.

The analysis above shows that the accessories must have good cushioning properties and an appropriate coefficient of friction. In addition, they should have sufficient fold resistance to maintain their shape during handling. During storage and transport, these accessories are generally not subjected to heavy pressure, so they don't need to bear much load. The edge compression strength and burst resistance of corrugated board, as specified in national standard GB/T 6543-2008 (S-2 and B-2.1), are usually sufficient for most applications, unless specific requirements are present.

A well-designed packaging system ensures that all necessary protective properties are provided without excess. Over-packaging leads to unnecessary waste and is not sustainable. To achieve the best balance between product protection and resource conservation, it's essential to use raw materials efficiently, design thoughtfully, and apply appropriate technologies. Based on practical experience, this article offers some suggestions for discussion and improvement in the field of packaging design.
