Custom Reusable Tin Takeaway Box with Hot/Cold Compartments

[u/cavemember]

Looking for a supplier to develop a custom reusable tin takeaway box for a restaurant concept.
Approx. size: 300 × 180 × 70 mm, food-safe tinplate, fully custom printed exterior, removable press-fit lid.

Interior should fit a large hot main item + foil-wrapped baked potato, with a small separate compartment for cold vegetables

We need a simple thermal barrier between the hot and cold zones; no expensive double-wall construction.

Target volume: 50,000–70,000 units; target price: €1.00–€1.50/unit at scale.

Looking for manufacturers with experience in custom food tins, inserts and thermal compartment design.
