Common options include disposable squeeze pouches for pump-to-bag use, reusable breast-milk bottles, plastic food containers, tempered glass containers, and portable insulated coolers for transport and short-term storage.
Common leak-resistant features include threaded or twist-lock caps on pouches, screw-on solid lids for bottles, and airtight multi-latch lids on food containers.
Many systems provide direct pump-to-bag connections using twist or snap adapters that fit major pump brands. Some packages include pump and nipple adapters so pouches can attach to pumps or to feeding bottles.
