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, which can help present it. But every window is also a hole in the board - and it affects strength and production.

Consider whether a window suits the product and, if so, where to place it and how large to make it, to keep a stable structure and a clean look.

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 can help the customer assess the product on the shelf. Place it to show the product's best part, not the inner packaging.

02. The structural cost

Cutting a window can reduce wall stiffness, depending on its size and the structure. A transparent film or additional reinforcement may be used to suit the product. 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.
