Will glass storage bottles be attached with active substances? The raw materials of glass bottles are natural, and plastics are chemicals. No matter how environmentally friendly plastic is advertised, it is harmful to human body, especially if the articles are left for a long time, the chemicals in the plastic will volatilize or react with the stored substances. There are rumors that glass bottles will absorb nutrients from breast milk. American experts have confirmed that glass bottles will not absorb any nutrients in breast milk and will not add any harmful substances to breast milk, so glass bottles are the safest. Plastics include PC (polycarbonate), PES (polyethersulfone resin), PP (polypropylene) and PPSU (polyphenylene sulfone resin). PPSU, PES and PC are light in weight, high in strength, not easily broken, high in transparency and good in performance. Plastic storage bottles are easy to turn yellow or opaque after a long time, so it is difficult to check whether the storage bottles have been washed. Some will be deformed after cooking and disinfection, and their service life will be short. But the biggest advantage of plastic storage bottles is that they are light, unbreakable and easy to carry.
The glass storage bottle has strong heat resistance and deformation resistance. The more heat-resistant, the less prone to deformation. The scale has good wear resistance, easy control of feeding quantity and good transparency. Large-diameter glass storage bottles are becoming more and more popular among the public. Compared with the standard caliber, the wide-caliber glass storage bottle is more convenient to clean and can be converted into a nursing bottle. Glass bottles have the longest service life, and the capacities of glass storage bottles on the market are usually 120ml, 150ml, 220ml, 240ml, etc. Mothers choose to buy according to their actual situation. Glass bottles are better than plastic bottles, but they are not strong enough and fragile.
