Which container type houses the primary container?

• A. Primary
• B. Shipping
• C. Secondary
• D. Outer

Answer: (C)

In packaging design, containers are organized in layers. The primary container is the innermost unit that directly holds the product. The container that surrounds and protects this primary unit, and often groups multiple primaries for retail, is the secondary container. The outer container, used mainly for transport, surrounds the secondary units to protect them during shipping. So, the container that houses the primary container is the secondary container.
