Cushion Materials

Cushion Material example

Cushion Materials are those package system components designed to absorb impact and vibration which is typical of product distribution. Cushion systems may be fabricated from a wide variety of materials but most common are polymeric foams, cellulose-based structures, and similar. All cushion systems function the same way regardless of their material or structure: they “give” or deflect in response to a shock input. By so doing, they change the shape of the shock input from something that is likely to cause damage to the product, to a different shape with a lower deceleration level - hopefully below product fragility levels. To properly engineer a cushion system, data must be available on both shock and vibration response characteristics of the material itself. Westpak is well-equipped to provide cushion shock absorption information (cushion curves), as well as cushioned vibration attenuation data (amplification/attenuation plots). Many of the cushion systems in use today have resulted from data generated by Westpak laboratories.
