If your microwave model has a glass tray or turn table, then follow the instructions printed on the popcorn label and place the bag on the turn table.

In some instances, if you have a metal turn table (instead of glass), you do need to set the popcorn bag on a popcorn/bacon plate.

This plate will lift the popcorn bag off of the microwave’s metal turntable, which can otherwise interfere with the metal contained in the popcorn bag.
