A breast milk collection system includes a storage bag and at least one coupling member formed separately from the storage bag and defining a first side and a second side. The storage bag includes a storage chamber, a closure strip for selectively closing the storage chamber, two bag flaps each extending away from the closure strip, and two coupling components each coupled to a different one of the two bag flaps. Each of the two coupling components includes a plurality of flap protuberances. The first side of the at least one coupling member includes a plurality protuberances extending therefrom, and the second side of the at least one coupling member is at least partially covered with adhesive for selective application of the at least one coupling member to a breastpump apparatus. At least one of the two coupling components selectively couples with the at least one coupling member.
