The display window

When a window helps the sale and when it just weakens the box — and the right balance between them.

The display window

A window lets the customer see the product itself, a clear selling advantage. But every window is also a hole in the board — and it affects strength and production.

The question isn't whether to add a window, but where and how large, to keep a stable structure and a clean look.

The display window

A good window shows exactly what it needs to — and not a centimeter more.

01. When a window works

A window pays off when the product is the selling point: a sweet, a beauty product, an item with distinctive color or shape. There the window shortens the customer's decision at the shelf. Place it to show the product's best part, not the inner packaging.

02. The structural cost

Every window weakens the wall and sometimes needs a PVC pane or extra reinforcement. A window that's too large or too close to a fold line can warp the box in transit. Good design keeps clearance from the folds and balances product visibility against box stability.
