Best choice by use

- Lunch boxes and travel: stainless steel for durability, or lightweight leak-proof plastic.
- Dry storage: plastic or glass jars for dal and snacks.
- Freezer: freezer-safe plastic or tempered glass, leaving headspace.
Plastic safety tips
- Choose BPA-free, food-grade plastic and check for microwave-safe labelling.
- Avoid heating oily food in old, scratched plastic.
- Replace boxes that are cracked, warped or smelly.
