In composite packaging labeling, what does the second letter represent?

• A. Outer Receptacle
• B. Inner Receptacle
• C. Packaging Color
• D. Cap Material

Answer: (A)

In composite packaging labeling, the letters indicate which part of the packaging the mark refers to—the inner and outer receptacles that make up the composite package. The second letter identifies the outer receptacle, meaning the outer container that surrounds the inner receptacle and provides the primary barrier to the contents. This helps anyone handling or inspecting the package know which layer’s integrity and conformity to standards is being addressed. Packaging color or cap material aren’t part of this labeling designation, so they aren’t indicated by the letters.
