The Complete Handbook of Packing Materials

Chapter 1: Understanding Packing Materials

Packing materials exist to do one thing: keep goods intact from the moment they're placed in a box until they're removed at their destination. That sounds simple. In practice, it requires understanding what forces damage goods during shipping, which properties of materials actually matter, and how to match material to scenario. Most professionals learn this through failure—a shipment arrives with broken glass, crushed electronics, or rusted metal—and then they guess what went wrong. This chapter cuts through that guesswork by explaining how packing materials work in the real world.

What Packing Materials Actually Protect Against

Goods are damaged during shipping by three primary forces: shock, vibration, and environmental exposure. Understanding these forces is critical because different materials protect against different threats, and using the wrong material—no matter how well-intentioned—leaves goods vulnerable.

Shock is an sudden, violent impact: a package dropped from a loading dock, a pallet hitting the floor during unloading, or a sudden stop during transport. A wine bottle packed in a cardboard box with no cushioning will shatter when the box is dropped three feet. Shock damage accumulates—multiple smaller impacts during transit can crack a component that survives a single large drop. Cushioning materials (foams, air pillows, paper) are designed to absorb shock by deforming under load and dissipating the impact energy over time rather than transmitting it directly to the goods.

Vibration is repetitive, smaller movements: the constant jostling of a truck driving over roads, the vibration of a conveyor system, or
