Plastic vs Stainless Steel: Which Is Better for Your Child?

When it comes to packing your child’s lunch, what’s on the inside matters—but so does what it’s packed in. From drink bottles to cups to bento lunch boxes, the choice between plastic and stainless steel can impact your child's health, your family’s eco footprint, and even your daily routine.

More parents are moving away from plastic and making the switch to high-quality stainless steel drink bottles, cups, and lunch boxes—and for good reason. Here’s what you need to know before your next school shop.

1. Health and Safety

Plastic containers and bottles may be labelled BPA-free, but that doesn't mean they are chemical-free. Over time, even "safe" plastics can break down and leach toxins—especially when exposed to heat or acidic food and drinks.

Stainless steel is naturally non-toxic, BPA-free, and chemical-free. Whether it’s a cup of warm milk, a cold juice bottle, or a tomato pasta packed in a bento, stainless steel keeps food and drink safe without absorbing odours or altering taste.

2. Built to Last – Everyday Durability

Lunch gear gets used—and abused—every day. Plastic bottles crack, warp in dishwashers, and often require replacing each term.

In contrast, stainless steel products like Ecococoon’s insulated drink bottles, reusable cups, and leak-proof lunch boxes are built to last for years. They can handle rough play, being tossed in school bags, and repeated washing without losing functionality or style.

3. Eco-Friendly and Sustainable

Australians throw away over 1.5 billion plastic bottles every year. And lunch boxes? They're among the most commonly discarded school items by the end of term.

Switching to stainless steel means you’re helping reduce plastic waste while teaching your child the importance of reusable, long-lasting products. Every time they take a sip or unpack lunch, they’re making a small eco-conscious choice that adds up.

4. Designed with Parents and Kids in Mind

Modern stainless steel lunch gear is anything but boring. Take Ecococoon's Leak-Proof Bento 5—its removable silicone seal keeps every bite separate and fresh. The insulated drink bottles let kids sip straight from the cap (no hands or teeth needed), and the cups are perfect for smoothies, yoghurt, or fruit salad on the go.

Kids love the colours. Parents love the practicality. Everyone wins.

5. Better Value in the Long Run

It’s tempting to choose plastic lunch sets because they’re cheap up front. But between cracking lids, worn-out bottles, and constant repurchasing, the costs quickly add up.

Stainless steel options cost a little more initially—but they last. You’ll save time, money, and stress across the school year.

Final Thoughts

If you’re looking for safer, smarter, and more sustainable lunch gear, the answer is clear: stainless steel beats plastic.

From bottles to bento boxes to snack cups, Ecococoon offers stylish, functional solutions that make healthy habits easier for your child—and better for the planet.
