Is Your Child's Lunch Box Hiding Harmful Chemicals?

Is Your Child's Lunch Box Hiding Harmful Chemicals?

And why "BPA-free" doesn't tell the whole story.

Most parents check for "BPA-free" before buying a lunch box. It feels like due diligence — and it is a start. But there's a question most labels still won't answer: what is your child's food actually sitting against, all day, every day?

BPA-free tells you what's not in the plastic. It doesn't tell you what the food is touching.

The Real Question Isn't "Is There Plastic?" — It's "Where Is the Plastic?"

This distinction changes everything.

A lunch box can be labelled BPA-free while still having plastic surfaces in direct contact with your child's food. BPA-free means one specific chemical has been removed — it doesn't mean the material is inert, won't leach under heat or acidity, or won't degrade with repeated washing.

When you pack fruit, tomatoes, yogurt, or anything warm, acids and heat are present. And with most plastic containers, those conditions accelerate chemical transfer from container to food.

The question to ask: is the plastic touching my child's food?

Food Contact Surfaces: What You Actually Need to Know

The food contact surface is the part of the container that directly touches the food. In most conventional lunch boxes and bento boxes, that surface is plastic.

Three factors increase risk with plastic food contact surfaces:

• Heat — warm or hot food speeds up potential leaching
• Acidity — fruits, sauces, and dressings are reactive
• Wear over time — plastic degrades with repeated use, UV exposure, and dishwasher cycles

This isn't a reason to panic. It's a reason to be specific about the material that actually meets the food.

How nom° Is Built Differently

We designed nom° around one principle: food should never touch plastic.

Stainless Steel Interior
No pores. No odour absorption. No staining. The same material used in professional kitchens worldwide — because it works.

Food-Grade Silicone Seal
Heat-resistant, odour-free, and fully removable. Pop it out, run it through the dishwasher, snap it back. No residue, no hidden buildup.

BPA-Free Structural Parts
The outer components that hold everything together are BPA-free — and they never touch food. That's the right place for plastic in a well-designed lunch box.

BPA-Free vs. Food-Safe: The Difference at a Glance

BPA-free is a start. It's just not the finish line.

Why This Adds Up Over Time

Most children eat from the same container, five days a week, for years. The material that touches their food — every single day — matters more than any single label.

We're not here to create fear around lunch. We're here to make the right choice simple. When you know what to look for, it comes down to this: stainless steel interior, food-grade silicone seal, and a brand that designed with that intention from the start.

That's nom°.
