Bakery and food packaging is judged in the first two hours: does the box hold its shape in a chilled cabinet, does grease reach the outside, does it fold fast at 6 a.m. when the counter is busy. Print quality matters, but it is third on the list.
The failures that show up again and again in this category — and where most of the engineering effort actually goes.
"Greaseproof" on a paper spec sheet means very little. The measurable version is a kit rating from 1 to 12 — a butter pastry and a fried item need different numbers, and a box that passes at 3 hours can fail at 24. We run the kit test with your actual product.
A PET window glued into a paper box makes it a mixed-material pack. That is fine, but it must be declared, and in some EU markets it changes the EPR fee band. Paper-only lids with a printed "window" are a real alternative for shelf appeal.
Self-locking bottoms and clear fold lines save seconds per box, and seconds per box is labour cost. We test assembly with staff gloves on — a structure that folds easily on a desk can be miserable with flour on your hands.
A chilled display cabinet sits near 80% relative humidity. Standard board softens and corners collapse within a day. FBB or a coated grade keeps the shape; the difference is invisible on a spec sheet and obvious on a counter.
Treat these as anchors, not limits. Everything is adjustable; the point is to show what the budget buys at each level so the first conversation is about substance, not about price alone.
Counter boxes, pastry boxes, takeaway. Fast to fold, cheap to repeat.
Retail bakery — product visible, grease contained.
Celebration cakes, corporate hampers, gifting.
Food contact is the one area where the paperwork is as important as the print. Every order ships with a declaration.
| Requirement | What it demands | How we handle it |
|---|---|---|
| EU 1935/2004 + GMP 2023/2006 | Materials must not transfer constituents in unsafe amounts | Food-grade board and inks; declaration of compliance (DoC) per order |
| US FDA 21 CFR 176.170 | Components of paper in contact with aqueous and fatty foods | Migration-tested coated board or liner; DoC available for US customs |
| TAPPI T559 kit test | Grease resistance matched to the food type | Tested with your product; the required kit level is written onto the PO |
| EN 13432 compostability | Only claimable if the entire pack is certified | We separate the two claims: "paper-based and recyclable" vs "certified compostable" |
Direct contact with food is a different approval path from secondary packaging. Tell us which one you need — it changes the board grade and the paperwork.
Yes, with every food-contact order — EU 1935/2004 and the GMP regulation, plus FDA 21 CFR 176.170 wording if the goods are US-bound. Ask for it at quotation stage so the board grade is chosen to match.
Usually kit level 8 or above for fried and oily items, 4–6 for baked goods. Send us the product and we run the kit test rather than guessing from the description.
Only if the window is paper or the whole pack is certified for the stream you claim. A PET window in a paper box is recyclable in most European paper streams only when the consumer removes it — so we would print a removal instruction, or quote a paper-only alternative.
Send the product, the quantity and any compliance requirement you are working to. You will get a structure proposal and a cost band, not a brochure.
