What Performance Should Air Cushion Packaging Products Have?

With so many types of air cushion packaging products on the market, which one has the best cushioning performance to truly protect items? To know which cushioning material is good, we must first understand what basic properties they should have.Now we will explore the hidden attributes of the air packaging category together.

The vibration reduction ability of air cushion packaging

During transportation, handling, and loading and unloading, items not only experience impact force from external forces, but also must withstand acceleration shock forces when vibrating. If the natural frequency of the goods is the same as the frequency of the vibration force, the packaging product will resonate and increase the amplitude, making it prone to damage. Therefore, the cushioning material made by the air cushion machine should have the ability to absorb vibration and achieve attenuation vibration performance.

The load capacity of air cushion packaging

The cushioning material deforms when loaded. The degree to which the deformation disappears and returns to its original shape after removing the external load is called the recovery. That is: good recovery from static loads and impact and dynamic loads that cause deformation. For materials with high energy absorption but poor recovery, they are not suitable as cushioning materials.

The absorption capacity of air cushion packaging

Generally, rigid cushioning materials have greater energy absorption capacity and are suitable for occasions with less impact force. The cushioning material should be able to absorb the energy generated by the impact, but pay attention to the size of the material's absorption capacity and adapt to the impact force received. Therefore, when selecting air cushion packaging materials, appropriate materials should be chosen based on the stress-strain curve of various materials.

Compression creep cushioning packaging material undergoes slow deformation over time under continuous static loads, and this compression creep deformation should be as small as possible.

Applicable temperature and humidity cushioning packaging materials can maintain their good cushioning performance at low temperatures, such as: polyurethane foam can be used at -20℃, and PS foam can be used at a minimum temperature of -20℃. PE foam can be used at -50℃.

Looking at the current cushioning packaging market, there are traditional cushioning materials such as foam, pearl cotton, and paper, but these materials have average impact resistance and are difficult to achieve modern transportation cushioning effects. Products are easily damaged. Secondly, the packaging of these materials is not neat with low grade.
