The oldest trick in retail
A window is a die-cut opening in the box — classically backed with a clear PET film — that lets the customer see the product without opening anything. It is the oldest merchandising move in packaging because it works: for products whose colour, texture or craftsmanship is the selling point, a window converts better than any photograph of the same item.
Where windows earn their cut
- Soaps, candles and cosmetics — colour and texture are the pitch
- Bakery — the product is the advertisement
- Craft and handmade goods — proof of the making
- Toys and collectibles — the item sells itself to a child or a collector
- Any product where “what you see is what you get” reduces returns
The trade-offs, stated
A window weakens the panel it cuts, adds a lamination or film step, and — with PET film — blocks recycling of that panel. The alternatives: an open-top tray with a sleeve, a die-cut hole with no film for products that do not need the barrier, or recyclable film alternatives where they are genuinely accepted. We quote windows with the strength and recycling consequences visible, so the display decision is an informed one.
