Your A Bait will look exactly like freshly rolled bait but it does not need freezing. It does not need any special storage but you should avoid exposing it to extremes of temperature.
Bright sunlight on the plastic will cause condensation the same as frost will. Any extra moisture that gets in the bait will stop it keeping well.
I recomend that when the bait arrives you should take it out of the plastic in case it has sweated and either dry it in the air for an hour or so or tip it into a cardboard box for a similar amount of time.
It can be dried a little more if you want a harder bait or simply put back into the bag or a bucket.
if you want to freeze it you can but at this stage it will become freezer bait and should be treated as such
