Baby Feeding Bottle Making Machine
11 videos • 1,965 views • by HassanPlas PP (polypropylene) milk bottles are the most common kind of plastic feeding bottles. They are durable, flexible and economical. Used to manufacture household items, PP milk bottles are available in clear and color-tinted transparency (like those of sports water bottles). Though PP bottles can withstand heat of up to 120°C, they may lose transparency over time with frequent sterilization and exposure to boiling water. This is not a good sign as it indicates a chemical component breakdown of the bottle’s plastic makeup. For this reason, it is recommended to change your PP milk bottles once every 6 months or when you notice a change in the bottle’s texture.
