THERMAL SHIELD ANATOMY
Click on each material layer to reveal its engineering properties and role in locking temperature.
Seamless PEVA Lining
The innermost layer is constructed from food-grade PEVA foil. Instead of stitching, which leaves needle holes for liquids to leak, we use thermal hot-press fusion. This creates a 100% watertight barrier that prevents sauce leakages and permits direct ice loading.
