storage bottles

Storage bottles and containers are made from a variety of materials, including plastics (such as polyethylene and polypropylene), silicone, glass, stoneware, stainless steel, and recycled PET (e.g., items made with 60% recycled PET).

Capacities span a wide range, from small 5 fl oz containers up to large 105 fl oz canisters. Common sizes you’ll see include 5 oz, 6 oz, 11 fl oz, 16 oz, 18.7 fl oz, and 72 fl oz.

Many storage options are described as compact and travel-friendly; some are sized to fit bag pockets or to replace bulkier coolers. Travel suitability varies by product, so check product dimensions, insulation claims, and customer reviews to confirm fit and performance for your needs.

Common closures include threaded or screw-on lids, attached snap caps, pour spouts, and snap-on covers. Lid materials reported include plastic, wood, and stainless steel. Threaded and screw-on designs are frequently noted for reducing leaks and creating a secure seal.

Breast-milk storage options often include pump-to-bag or pump-compatible designs, pre-sterilized bags or bottles, clear measurement markings, and threaded/screw-on caps to reduce leaks. Some sets also include pump adapters, feeding nipples, and accessories for warming or thawing.
