While glass is heavier and sometimes more difficult to store, there are several benefits of using glass over plastic.
For example, glass is easy to clean and is often safe to use in the microwave, oven, and freezer without the risk of harmful chemicals leaching into your food. Plus, it's less likely to stain or retain odors and more eco-friendly (1).
If choosing plastic, select a product made from BPA-free plastic. Some plastics are also more stain- and odor-resistant, so they're better options if you regularly store foods such as red sauces and curries.
