The problem
The brand ran its hot line in PP clamshells. Two pressures made that untenable.
The first was regulatory: single-use plastic restrictions and the packaging waste regulation pushed every food service operator in Germany to justify plastic on the menu. The second was commercial — their retail partners began asking for a plastic-free claim in writing, and "recyclable PP" was not the answer they wanted.
The obvious swap was bagasse. The non-obvious part was that bagasse is not a drop-in replacement: it is thicker, it stacks differently, and its oil resistance depends entirely on the fibre and the pressing, not on a coating you can add later.
What we specified
Three formats, all molded, all the same fibre source so the colour stays consistent across the menu.
- GR-C06 — 8-inch clamshell, three compartments, hinged lid, for the hot main plus two sides
- GR-P15 — large 5-compartment tray for the sharing and family SKUs
- GR-H04 — 800 ml single-compartment lunch box for the cold line
The lid was the hard part. A bagasse clamshell that does not latch is worse than a PP one that does, because it opens in the bag. We asked for the hinge and the two locking tabs to be checked on the actual filled weight, not on an empty sample.

How it was produced and checked
- Tooling from the buyer's existing PP footprint. The tray had to fit the same cooler bags and the same sealing film, so the outer dimensions were fixed and the compartments were arranged inside that envelope.
- Oil resistance test. Hot chicken and a cream sauce at serving temperature, held for the length of a delivery window, checked for wicking at the corner radius.
- Microwave check. Two minutes at 800 W, then a stack test while still hot — this is where thin-walled bagasse fails.
- Stack and load. Pallet pattern rebuilt for the new wall thickness; the case count per pallet drops, which is the part buyers underestimate.
- Pre-shipment. AQL sampling, plus a retained filled sample per lot for the buyer's own shelf-life trial.
What changed for the buyer
- The plastic-free claim became documentable. Compostability certificate and declaration of compliance per SKU, in the format their retail partners accept.
- No lining to declare. The oil resistance comes from the fibre and the press, so there is no coating to interrogate under PFAS rules.
- A real cost trade-off. Bagasse takes more cube per unit than PP. Freight per meal goes up; the brand absorbed it because the plastic-free claim was worth more than the delta at their price point.
Documents supplied with each order
- Declaration of compliance (EU 1935/2004)
- Migration test report for the finished article
- Compostability certificate — checked per SKU, not per material; a certified fibre does not make a certified box
- BRC A-grade certificate of the producing plant
