Which method of packing might require the use of a suspension system?

The use of a suspension system in packing is particularly relevant when transporting delicate items. Delicate items are susceptible to damage from shocks, vibrations, and impacts during transport. A suspension system helps to absorb these forces, ensuring that the items remain secure and protected throughout the journey. This method typically involves using padding, cushioning, or a framework that holds the delicate items in place while allowing some degree of movement to counteract potentially damaging forces.

In contrast, storing, shipping heavy machinery, or packing bulk items generally require different packing strategies that focus less on cushioning and more on stability and strength. While it is important to ensure that these items are well-packed, the need for a suspension system is not as critical as it is for delicate items, which must be handled with an extra level of care to prevent damage.
