Wall Height Controls Access
A tray becomes harder to use as soon as its walls rise higher than the product requires.
Low walls leave more of the product exposed, make top-loading easier and reduce how far someone must reach into the pack. Taller walls add containment and branding area but can obstruct removal, hide the product or make assembly more involved.
That wall-height decision is more important than treating a tray as a shallow version of a conventional box.
Custom Tray-Style Folding Cartons work best when the open top is intentional. The folding carton structure still uses die-cut and creased paperboard, but the tray removes the normal top closure so access and presentation become part of the structural specification.
Low Walls Favor Presentation
Shallow side walls suit products that should remain easy to see and lift.
Wrapped confectionery, cosmetic sets, apparel accessories and compact product kits can sit neatly in a tray without disappearing behind tall paperboard. The wall only needs to retain the product enough for the intended handling.
Too much height can turn an open tray into an awkward box without giving it the protection of a true lid.
Taller Walls Add Control
Higher tray walls make more sense when products need greater lateral restraint or when the tray serves as an inner component inside another pack.
The wall should still stop short of interfering with fingers, inserts or product removal.
For multi-item sets, decide how the products will be picked out before increasing tray depth merely to create more paperboard around them.
