Clamshell Box

Approve the exact hinge location, cavity depths and meeting edges on a structural sample. Check how the loaded pack rests when open and which half holds the product. The clamshell name does not specify every lid-wall or closing detail.

Define the intended display angle and surface, then trial the filled sample for tipping, lid movement and access. The opening should expose the product without requiring a customer to hold the lid constantly. Do not assume the hinge acts as an angle stop.

Position the insert and loose accessories away from the moving joint, then close and open a packed sample. Check soft pouches and leaflets as well as rigid items. Any hinge gap needs review in the final configuration rather than only in an empty mockup.

Inspect alignment around the closed perimeter and check whether an overfilled insert holds one side open. Trial the proposed closure and wrap together. Agree on the cosmetic meeting line while separately evaluating how the filled pack remains closed during handling.
