A tray for Wal-Mart house brand frozen lasagna that cuts microwave cooking time in half has won an award from the Institute of Packaging Professionals.

Wal-Mart switched its Great Value Lasagna to a MicroRite tray from Graphic Packaging Int’l, which features aluminum and polyester laminated to a paperboard base. The aluminum concentrates and distributes the microwave energy, for faster, easier heating. Use of the susceptor also improved product quality by eliminating overcooked “hot spots” and undercooked “cold spots.” Cook time in the microwave decreased from 28 minutes with the former packaging to 13 minutes with MicroRite.
