Castella Cake Thermoforming Vacuum Packaging Solution

Castella cake is delicate, airy, and highly sensitive to moisture loss. Utien Pack’s MAP thermoforming packaging solution uses flexible bottom film to form soft-supporting cavities that protect the cake’s structure while maintaining its signature moist texture. Modified Atmosphere Packaging replaces oxygen with protective gases, slowing staling and extending freshness for bakery shelf life.
