TRANSIT
A parcel is dropped, stacked and left in the rain.
A pack is asked to do several different jobs in sequence, and the order matters. What follows is what actually happens to a parcel and which decision answers each stage.
- Filling
- The pack is loaded and closed. Void here becomes movement later
- Palletising
- Weight is stacked above it. This is the longest-acting load
- Loading
- It is thrown and caught. Each transfer is a drop of some height
- Carriage
- It vibrates for hours. Contents settle and abrade
- Storage
- It sits in humidity, and board loses stiffness as it takes up water
- Unloading
- It is dropped again, on a surface that is usually harder than the last
Illustrative transit record
| Stage | What is tested | How it is tested |
|---|---|---|
| Drop | Whether the pack and contents survive | Drops onto a hard face, at the declared height |
| Stacking | Whether it holds the load above it | Held under load for a period, in humidity |
| Vibration | Whether contents abrade or settle | Shaken at the frequencies of carriage |
| Humidity | Whether the board is still stiff | Conditioned, then re-tested |

Why humidity is the test most often skipped.
Because it takes time and changes nothing visible. Board that has taken up water is measurably weaker, and a container journey supplies the humidity for free.
The question worth asking instead.
What the stacking strength is after conditioning, not before. A supplier who can answer that has tested the pack in the condition it will actually be in.
