All _______ ______ must pass a test that includes the size, material, thickness, manner of constructions and packing, and any surface treatments used.

• A. packaging designs
• B. packaging materials
• C. container designs
• D. packaging specifications

Answer: (A)

The main idea is that the item being evaluated is the packaging design itself, because a test for packaging considers how the design will perform in real handling and transport. The test looks at the design’s size and materials, including thickness, how it is constructed and packed, and any surface treatments used. These elements determine whether the package can safely contain and protect its contents, withstand handling and stacking, and meet applicable requirements. Focusing on packaging materials would only assess material properties, not how those materials are combined and finished in the final package, and packaging specifications are a set of requirements rather than the tested object. Therefore, packaging designs best fit the description of what must pass the test.
