Is It Okay To Freeze Water Bottles?
Yes, it is okay to freeze water bottles. Freezing plastic water bottles will not harm the bottle or cause any chemical leaching. However, it is recommended to leave a little bit of room at the top of the bottle to allow for expansion when the water freezes. Additionally, it is important to note that freezing water in a bottle with a screw-on cap can cause the cap to crack or leak when the ice expands, so it is best to use a bottle with a wider mouth and lid.
