In the face of the market in a variety of cushioning packaging materials, which kind of material cushioning performance is better, can the real protection of goods?
Today to understand the performance of cushioning packaging materials:
1. Determine the vibration absorption capacity of the packaging material. Goods in the transport, handling, loading and unloading process, in addition to the impact of external forces, but also to withstand the vibration of the acceleration momentum, vibration outside the packaging products produced resonance phenomenon, increase the amplitude and easy to cause damage.
Therefore, the cushioning material should have absorbing vibration force to achieve attenuation vibration performance.
2. Test the recovery capability of the packaging material. After the cushioning material plus the load produces the distortion, when eliminates the additional load, the material deformation disappears restores the original shape the degree to be called the resilience.
Material load is subjected to long-term static pressure load and shock, vibration load, the difference between the former is static recovery, the latter for dynamic recovery, the absorption of energy and poor resilience of the material is not suitable as a buffer material.
3. Assess the absorption of the impact energy of the packaging material. General hard cushioning material, with a larger impact energy absorption, adapt to the impact of small occasions, cushioning materials should be able to absorb the impact of the energy generated, but to pay attention to the material absorption capacity and the impact of the energy to adapt, is not the more absorbent material is the better. Therefore, when selecting the cushioning material, the appropriate material should be selected according to the stress-strain curve of various materials.
