Corrugated packaging boxes rely on a fluted middle layer to give strength and cushioning without excessive weight. That structure is why corrugated is the default for shipping and storage: it resists crushing, absorbs knocks and holds its shape through a busy supply chain. The fluted core is what gives corrugated its strength-to-weight, which is why it remains the default for shipping and storage.
Matching flute and wall to the load
Made to your custom size in corrugated cardboard, the box can be specified with a wall strength that suits the weight and handling. Heavier or stacked loads call for more board; lighter goods can run leaner. Sizing the box closely to the product cuts both the void fill you buy and the movement that damages contents.
Specifying the box
- Internal size matched to the packed product
- Wall strength chosen for weight and stacking
- Plain or printed outer as the use requires
If you are unsure of the specification, pack a prototype at real weight and check it under a stack before you commit to a run. Getting the wall right is a balance: too little and goods are at risk, too much and you pay for board you do not need.
