Detachable coding elements let stackable containers be reconfigured for correct stacking, group separation, and easy retrofitting.
A bakery dolly deck features a peripheral lip with a ramped portion to guide stacked trays onto the support area.
A cellulose container skeleton uses alternating thin and thick zones to reduce material consumption while maintaining structural stiffness.
Preliminary perforation of flat plastic sheets reduces material consumption by 65% while maintaining tray strength during deep thermoforming operations.
Exterior channels receive interior ribs to prevent tipping of non-uniform materials during stacking.
