Did you pack that yourself?
Bread from the in-store bakery often comes in thin film or open wrappers and will probably need to be repacked in a good freezer bag with a clip before freezing. A good clip on the end of a freezer bag containing uneaten garlic bread will also help prevent the smell tainting other food.
We always try to convince ourselves that we will remember what’s in the freezer containers, but after a few weeks we really won’t. Labels and a good thick black pen are worth investing in as they prevent horrible combinations of food being defrosted by mistake!
