5. Are All Plastic Bottles Unsafe?
You may be wondering now if all plastic bottles are unsafe to be reused. The good news is that not all plastic water bottles are unhealthy to be reused. You can use bottles made out of polypropylene, which is typically a white plastic. They are the types of non-reactive plastic bottles that are mostly used in the labs.
However, little is known about the manufacturing process and other additives that go in the making of such bottles and hence it is always better to wash them properly and regularly to keep the bacterial growth at bay.
