Breast milk combines the best possible nutrition with vitamins, proteins and immunological agents that help babies grow and develop and protect them from infection.Lansinoh’s Breastmilk Storage Bags are ideal for storing expressed breastmilk in the fridge or freezer, lying flat or standing up and now come with a hygienic tamper-evident and secure tear-away top, with a double seal to prevent spills or leaks. The bags also have double-sealed side seams for extra strength, and are pre-sterilised and plasticiser-free, they’re also BPA/BPS free so no harmful substances can contaminate the stored breastmilk.The double zipper provides a secure seal and the easy pour design minimises the chances of spillages - there is even a convenient tab to note the date of expression and a ‘use by’ date. They’re a great way (if possible) for mums to create a bank of breastmilk that can be stored until they are needed, and because they are made from polyethylene they are food safe which means no toxins will reach the breastmilk.
