  • Drums
  • Jerricans (rectangular drums)
  • Boxes (if no inner packagings are used)
  • Bags
  • Barrels

This involves preparing samples of the packaging design, and running them through a gauntlet of tests that simulate common causes of package failures. These tests include a drop test and a stacking test, as well as others aimed at specific packagings, such as fibreboard components or wooden barrels.

Types of Single Packaging

Single packagings are divided into two types – those that will be used for solids only, and those that also can be used to ship liquids. The main difference is that those suitable Continue Reading…
