Oven Kraft by Convertech
Fiber-based baking & food packaging
G-Flute is an ultra-thin corrugated material we make ourselves from paper rolls, built for continuous industrial production lines. Trays made from it are fiber-based and dual-ovenable, from −28 to +220 °C: an alternative to aluminium foil and plastic trays that holds its shape through baking, freezing and transport, and lowers the cost of every unit that leaves the line.

Certified materials and production
Produced under Convertech’s certified quality and food safety management systems.
Solutions
Each line is built on the same G-Flute material and is engineered for a specific process, a specific product and a specific production environment.
Bakery
Loaf, rectangular, individual and specialty formats that run on filling lines, go through the oven and reach the shelf in the same tray.
Fresh produce
Treated corrugated material that manages the gases fruit releases in storage and transport, to reduce waste between grower and shelf.
Meat & seafood
Fiber-based bases for meat, fish, poultry and deli. They run on existing automated lines and finish with shrink or vacuum packing, replacing the plastic tray.
Bakery
We qualify each format against the tray it replaces, on the customer’s own line, with the same filling, oven profile and packing step.
Uniform trays for high-volume continuous lines, wet and dry batters.
Small formats matched to depositors and automatic filling lines.
One tray from oven to shelf, serving as baking form and retail display.
Traditional cakes and desserts baked in dedicated paper forms.
Total cost of production
Every pilot runs against your current tray and reports the full picture per baked unit. You see the numbers before you commit to volume.
