PPSU bottles are a great choice for babies as they are made of an extremely safe, non-toxic material that is completely free from BPA and phthalates. They offer superior thermal stability and have excellent resistance to high temperatures, allowing them to be boiled for sterilisation without the risk of cracking or warping. Additionally, PPSU offers the best hygiene and safety protection of any baby feeding bottle available due to its high heat resistance. PPSU bottles also last longer than many other types, offering a durable solution that will save you money over time.
