Package cushioning

Vibration and impact shock during shipment and loading/unloading are controlled by cushioning to reduce the chance of product damage.

Depending on the specific situation, package cushioning is often between 50 and 75 mm (2 and 3 in) thick.

Internal packaging materials are also used for functions other than cushioning, such as to immobilize the products in the box and lock them in place, or to fill a void.

It is often best to use a trained packaging engineer, reputable vendor, consultant, or independent laboratory.

This can be based on an existing specification, published industry standards and publications, field studies, etc.

[13] The process for vibration protection (or isolation) involves similar considerations as that for shock.
