Make sure none of the peaches are touching, or they'll freeze together. Cover the baking sheet with plastic wrap. Place the baking sheet in the freezer and leave it there until the peach wedges are frozen solid. You can use either tubs or freezer bags. Fill the container with the peach wedges, leaving a little room at the top. Since the wedges were pre-frozen, they shouldn't stick together. Label the container with the date the peaches were processed and stored. They should keep for 8 to 10 months.

Summary:
Place the peach wedges in a single layer on a baking sheet. Freeze the peaches. Put the peaches in a freezer food storage container. Store the peaches in the freezer.
