Types of Milk Bottles

There are many different types of milk bottles in the market. Often, parents are confused about the types of milk bottles and what makes them different? And how often should we change the milk bottles?

MILK BOTTLES CAN BE DIFFERENTIATE INTO PES, PP, PPSU, AND GLASS

What exactly is BPA Free?

BPA stands for Bisphenol A. BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s. Is a chemical that had been used to harden plastic. Some research has shown that BPA can seep into food or beverages from containers that are made with BPA. exposure of BPA is a concern because of possible health effects of BPA on the brain, behavior and prostate gland of fetuses, infants, and children. Although FDA, has said that BPA is safe at the very low levels that occur in some food but they are still continuing its review and research of BPA.

PP MILK BOTTLES (transparent, milky plastic) PP (Polypropylene), tough and flexible. Can only withstand temperature up to 120°C. A plastic mainly used in household items, reasonably economical. It’s transparent or can be colored using pigments. PP milk bottles will lose their transparency over time and frequent sterilization or boiling. Limited shelf life. Advised to change every 5-6 months, or where there is a change in texture. Most commonly use milk bottles in the market.

PES MILK BOTTLES (honey-colored tint) PES (Polyethersulphone), describes the family of thermoplastic polymers. These polymers are known for their toughness and stability in high temperatures. The size change when exposed to boiling water at 180°C. Is a new plastic to replace BPA. PES bottles have a natural honey-colored tint. Advised to change every 5-6 months, or where there is a change in texture.

PPSU MILK BOTTLES (Honey tinged) PPSU (Polyphenylsulfone)is high-performance thermoplastic offering better impact resistance and chemical resistance than PP and PES. It can withstand continuous exposure to heat and still absorb tremendous impact without cracking or breaking. Commonly use in aerospace and medical devices which required repeated sterilization. It has a high melting point of 207°C. It does not absorb odor or color. Naturally BPA Free.Can change yearly. More costly compared to PES/PP.

GLASS BOTTLES Glass milk bottles have been around for many years and commonly used during our grandparents time. But it’s not widely used during our parent’s era onward because glass is heavier and may cause danger to parents or baby when we drop the glass bottles. But it’s the only milk bottles which don’t leach or released chemicals when exposed to heat. A melting point of 1400°C to 1600°C, depending on the components. No change needed unless you break the glass, or there is cracks.

PLEASE DO NOT BOIL PLASTIC MILK BOTTLES!

Extract from AVA: *Do not put boiling water in baby bottles, as hot water causes bisphenol-A to migrate out of the bottle at a higher rate.*
