Smells slightly plastic - but is not dangerous and decreases.

When I had the bottle the smell of new plastic, I noticed.
Then I researched and compared.
The result is that all plastic bottles have such a smell. Have the business determined 10 different watched. Odor was not it.
My suspicion is that during the coating of the inside of the bottle, which is designed to protect against mold.
The processed plastic is namely polyurethane, and that's one of unbedänklichsten plastics. It is for example also used in medicine.

So the only odorless alternative seems to be a PET bottle. But does not stop at the wheel and is impractical.
