Freezer-to-oven CPET trays
A thermoformed tray of crystallized polyethylene terephthalate holds frozen, unbaked muffin batter and can be put right in the oven to allow foodservice operators in Australia to offer fresh-baked goods on-premise.
Bakels Bake-Off which produces the frozen batter in Sydney packs muffin dough into 4- 6- and 12-count black glossy CPET trays. They are then topped with locally sourced clear snap-fit PET lids. After cryogenic freezing at Foodservice operators remove the lids and place the trays from the freezer directly into 200°C (392°F) conventional ovens. The trays which resist melting distorting or cracking have been in use for about a year. The trays permit Bakels' customers such as BP Express stores and Coles supermarkets to offer consumers fresh baked-on-premise products without the expense of running a full-scale bakery operation according to Bakels sales manager Kevin Dryland. Neither account offered baked-on-premise products previously. The trays coded with Australia's equivalent to the "1-PETE" resin recycling code are recycled by some users. Future plans for the packaging call for a retail version for consumers says Dryland.
