Bento Box Showdown: Stainless Steel vs Plastic

When it comes to packing lunch, not all food storage is created equal. If you’ve been comparing bento lunch boxes online, it’s easy to get lost in a sea of lookalikes. But the materials used in your lunch container matter—a lot.

Welcome to the ultimate bento box materials showdown: stainless steel (with silicone inserts) vs plastic with plastic trays.

What’s in the Box?

Let’s break down the contenders:

• Smash Stainless Steel Bento Box: Features a tough stainless steel body with a removable, food-grade silicone insert. It’s microwave safe (yes, really), non-toxic, and lets you reheat or remove sections as needed.
• Plastic Bento Boxes: Usually made from polypropylene or mixed plastics, these come with plastic trays inside. While they may look similar on the shelf, they’re not created equal when it comes to heat, durability, or long-term safety.
