Open-Top Display Box — No Lid, Strong Base, Product on Show

The open-top display box is exactly that — four walls, a strong sealed base, and no top at all, so the product sits on show and stays easy to reach. The bottom is a full-overlap closure (all four flaps lapping over each other, doubled on board and sealed with tape or glue), and here it's doing structural work a lid normally shares: with no top tying the walls together, the base and the glued corner seam carry all the rigidity, so a well-made overlap bottom is what stops a filled box from splaying open. That makes it the go-to for anything meant to be seen and grabbed — retail dump and display bins, countertop impulse displays, shelf organisers and back-stock trays, gift-hamper and subscription-box bases, and open storage around a workshop or office. Two practical things follow from having no lid. First, height matters more than usual: the taller the walls relative to your board thickness, the more they bow outward when the box is full, so for a deep bin step up your caliper or the sides flare — a shallow tray-height box stays rigid on lighter board. Second, the top edge is the first thing a customer sees and touches, so treat it as a finished face — print or colour it if it's on display, and remember a raw cut edge exposes the board's inner liner. If you later need to close it, the same strong base comes with an integral tuck top on the overlap-bottom tuck box, or pair this open base with a separate lid using the lid box with base for a two-piece look. Set your length, width, and height — height especially, since it drives the whole feel from shallow tray to deep bin — and PackMyMan lays the overlap base and open walls out cleanly for your board, exporting a production-ready dieline in SVG, DXF, or PDF.
