Is the BMF tray microwave-safe?
Yes, that's precisely its purpose. Polypropylene can withstand temperatures up to 120°C, allowing for prolonged heating without deformation or migration. This is the fundamental difference compared to standard polystyrene deli trays.
Can it be frozen?
Yes, down to -20°C. Freezing and then reheating in the microwave is possible without transfer — one of the major commercial advantages of this format.
Is the hinged lid airtight?
Yes, for standard transport (home delivery, carrying). For complete sealing or prolonged inclined transport, use an additional film or choose a heat-sealable tray.
What is the difference between this and a polystyrene deli tray?
The deli tray (BC) is made of polystyrene (-40°C to +70°C) and is not microwave-safe. The BMF is made of polypropylene (-20°C to +120°C), microwave- and freezer-safe. The BMF is more technically advanced and more expensive.
