How to Swap to Non-Toxic tupperware:
Here's how to swap to non-toxic tupperware:
What to know about food storage containers
Food storage containers sit in direct contact with your food, often for hours or days at a time. The material they're made of matters because some containers can leach substances into food, especially when heated or used with acidic or oily foods.
- Containers used for hot food, microwaving, or long-term storage deserve the most attention since heat and time can increase what transfers from the container into food.
- Welpr prioritizes inert, non-reactive materials like glass, stainless steel, and ceramic over plastic for anything that touches your food.
Review what you already use
Take stock of the food storage containers in your kitchen and note what each one is made of. Focus first on containers you use most often or that regularly hold hot food.
- Flip containers over and check the bottom — plastic containers usually have a recycling number and may note "BPA-free," but this doesn't mean they're free of all plastics of concern.
- Set aside any plastic containers that are scratched, warped, stained, or discolored, as wear and tear can increase what leaches into food.
Use your current containers more safely
If you're not ready to replace all your plastic containers right away, a few simple habit changes can reduce what transfers from plastic into your food.
- Never microwave food in plastic containers — transfer food to a glass or ceramic dish before reheating.
- Avoid storing hot, acidic, or oily foods in plastic; let leftovers cool down first, and use glass for tomato-based sauces, soups, or fatty foods.
Choose cleaner replacements
The best food storage containers are made from materials that won't react with your food. Glass, stainless steel, and tested ceramic are all excellent choices that last a long time and keep food contact clean.
- Look for borosilicate or tempered glass containers with snap-lock lids — if the lid is plastic, make sure it's BPA-free and doesn't touch the food when sealed.
