For normal newborns, it is not required ( at least by most) to have the bags
sterile for storage of BM.  They can store in baggies, etc. if they so
desire, along with double bagging.  Some even use ice trays, again placing
them in a large zip lock bad freezer bag.  We don't require bottles to be
sterile.
 Do not forget that milk bank guidelines are only for NICU, hospitalized
infants.
