For many eco-conscious families, oven tray bakes are a popular choice, but the aftermath—a blackened, greasy oven tray soaking in a sink full of soapy water—is anything but. Bonnie Bio has introduced a “world first” solution that promises to end the era of scrubbing: pre-shaped, plastic-free oven tray liners.
What Makes Them Different?
Unlike traditional parchment paper that often slides around or leaks, these liners feature a continuous 2cm wall designed to contain all cooking oils and liquids. They are specifically designed to fit the standard trays that come with most ovens, making them an effortless addition to your kitchen routine.
The “Green” Factor
As a parent, you want to keep toxins out of your kitchen. These liners are made from responsibly sourced wood pulp and are entirely plastic-, chlorine-, and bleach-free.
Beyond being biodegradable, they offer a significant health benefit: they eliminate aluminum transfer. When cooking acidic or salty foods at temperatures above 200°C, metal can leach into your family’s meal. These non-stick paper trays create a safe barrier, ensuring your food stays pure.
Saving More Than Just Time
While the primary draw is the “guilt-free” convenience of binning them after a few uses, the environmental impact goes further. By eliminating the need for heavy scrubbing, your family saves on water, soap, and electricity used in long dishwashing cycles. For families with limited bench space, not having a massive roasting pan drying on the counter is a genuine win.

Family Project: The “Build-Your-Own” Pizza Station
One of the best ways to put these liners to use is a No-Mess Family Pizza Night. Because the liners have a 2cm wall and are non-stick, they act as the perfect individual “canvas” for kids to create their own masterpieces.
- Prep: Give each child their own Bonnie Bio liner on the counter.
- Create: Let them stretch their dough and pile on the sauce and toppings right inside the liner. The 2cm walls ensure that stray cheese or sauce stays contained and doesn’t end up all over your floor.
- Bake: Slide the liners directly onto your oven trays. The non-stick surface ensures the crust stays crisp and doesn’t stick to the bottom.
- The Best Part: When dinner is over, there are no floury counters to wipe or crusty pans to soak. If the liners aren’t too messy, you can even reuse them for a batch of cookies the next day!
Availability: You can find these liners at Checkers, Mambo, and Spar stores, or order them directly from the Bonnie Bio website.
