Start With the Filled Container
Custom Supplement Boxes should be sized around the production bottle, tub, jar, blister card or sachet bundle in its finished filled state. Closure height, cap diameter, label thickness, tamper band, leaflet and any accessories all affect the usable internal dimensions.
The outer carton is secondary packaging. Its job is to organize the primary container, create readable panel space, improve shelf presentation and support handling. It should not be expected to create product stability, freshness or compliance that belongs to the primary package.
Measure the Production Pack
Record the maximum width, depth, height and filled weight of the actual unit that will enter the carton. A lightweight capsule bottle and a dense powder tub can need very different board stiffness and bottom support even when their outside dimensions are similar.
Leave enough clearance for repeatable packing without making the carton so loose that the container rattles or shifts into the closure.
For conventional lightweight bottle cartons, Straight Tuck-End Cartons can keep packing simple while leaving broad printable panels around the container.
