How big should the window be?

Big enough to show the product clearly, but not so big it weakens the bag or exposes uneven items. Shape matters too — tall for a baguette, wide for a row of cookies. Tell us what goes inside and we'll size and place the window around it rather than using a template.

Are window bags recyclable?

Less cleanly than a plain paper bag — the window is a film, so it's not plastic-free and the window should be separated where your local stream needs it. If a cleaner end-of-life matters, we offer compostable or glassine windows that recycle or break down far better, and we'll be straight about the trade-off.

Can I use them for warm baked goods?

You can, but warm food sealed behind a solid film can sweat and soften the crust. For warm bakery we'd usually suggest a vented or breathable window so it stays crisp. Tell us if it's served warm and we'll spec accordingly.

What is the minimum order?

It depends on size, the window and how many print colours you run. Tell us your run and the window you want and we'll give you the exact figure; plainer setups are the most flexible.

Custom printed window SOS paper bags that sell the product on sight

Custom printed window SOS paper bags are designed to showcase the product directly at the point of sale. An integrated transparent window lets customers see what is inside, turning the bag into a visual selling tool rather than just a container — the product does part of the selling, and your print does the rest. Built on a block (SOS) base, the bag still stands upright, so the window faces the shopper instead of folding away.

A window that turns visibility into sales

These block-bottom (SOS) bags are widely used in bakeries, confectioneries, cafés and food-retail environments, where product visibility directly increases impulse purchases and enhances shelf appeal. Seeing the cookie, the pastry or the roasted coffee through a clear panel is often what tips a passing shopper into a buyer, so the window earns its place by doing a job a printed panel alone cannot.

Stable base, engineered window placement

The square base structure keeps the bag stable and standing, while the window placement is engineered according to product type, filling level and presentation needs. A window set too high shows empty bag; set too low it hides the product — so we position and size it around how the bag is actually filled and displayed, making sure the best of the product is what the customer sees first.

Recyclable kraft with greener window options

Manufactured from recyclable kraft paper with optional compostable or eco-friendly window materials, these bags balance product visibility with sustainability considerations. A conventional plastic window is the cheapest route but the part most likely to complicate recycling; compostable or paper-based window options keep the pack closer to a single material stream. We are honest about the trade-off so you can choose visibility and sustainability with eyes open rather than discover it later.

Designed around food safety and storage

Each design is evaluated based on food safety, storage conditions and recycling impact. Whether the contents are dry, greasy or moisture-sensitive changes both the paper grade and the window choice, so we match the build to how the product behaves on a shelf — keeping it safe to hold food, fit to store and as clean as possible to dispose of.

Sized and laid out to your product

Paper weight, window size and print layout are adjusted to match your product requirements, ensuring both structural performance and a strong brand presentation in retail environments. The print is arranged around the window so logo, message and product frame each other rather than compete, and the grammage is set for the load the bag carries — light for a single pastry, stronger for a filled grocery bag.

Sampling, colour matching and honest guidance

Before production we provide sampling and colour matching, confirming the print and the window on a physical sample before any run is committed. We also guide material selection — including whether a windowless or compostable-window version serves you better — based on recyclability, food-contact requirements and how the bag is sold and stored. Share your artwork, sizes and the product the bag will display, and we will develop a window SOS bag that shows the product, holds its shape and carries your brand.
