The best material for food storage containers is typically glass or food-grade stainless steel. Glass is non-porous and does not leach chemicals, making it safe for storing acidic or alkaline foods. Food-grade stainless steel is durable, does not react with food, and is easy to clean. Both materials are BPA-free and can be used in the refrigerator, freezer, or microwave. Avoid plastics with BPA or those that can leach chemicals over time, especially when storing hot or fatty foods.
