Plastic water bottles cannot be frozen because the water expands when it freezes, causing the plastic to become brittle and crack. This can release harmful chemicals from the plastic into the water, impacting its safety for consumption. Additionally, frozen water bottles are more likely to deform or burst, creating a mess.
Some eco-friendly alternatives to hard plastic water bottles include reusable stainless steel bottles, glass bottles, and biodegradable plant-based bottles. These options help reduce plastic waste and are more sustainable choices for carrying water on the go.
