Seal & Go — Leakproof, Plastic-Free Food Containers

The Elephant Box Seal & Go range is our answer to the plastic tub drawer everyone has hiding in their kitchen. These leakproof, BPA-free food containers swap yellowing, stained plastic Tupperware for food-grade stainless steel and silicone instead — nothing that leaches, stains or holds onto smells. Whether you need a snack pot for a toddler's lunchbox or a leakproof pot for salad dressing on the go, the range is built to be a genuine non-plastic alternative for everyday food storage, not just an occasional-use novelty.

Dressings, dips, sauces or small portions on the go → Dressing Pot Pair (2 x 50ml)

Why choose a stainless steel food container over plastic Tupperware?

Plastic Tupperware stains, holds onto smells, and eventually gets binned once the lid warps or the seal stops working. Elephant Box food containers are BPA-free from the outset, but they go further than that: the base is 304 stainless steel, so it's non-porous and won't stain or absorb flavours no matter how many times you use it for last night's curry or this morning's dressing. It's a genuinely non-plastic alternative, not just a plastic-free label on a plastic product.

Are these food containers really leakproof?

Yes — both the Snack Pots and the Dressing Pot Pair use a food-grade silicone lid that creates a proper leakproof seal, not just a loose-fitting cover. That means dressing, sauces, yoghurt or milk can go in a bag or lunchbox without a second thought.

What are they made from?

Every pot in the Seal & Go range has a base made from 304 grade stainless steel, with a lid made from food-grade LFGB certified silicone. No plastic touches your food at any point — it's BPA and phthalate free by design, not just by certification.

Are they dishwasher and freezer safe?

Yes — every pot in the range is dishwasher and freezer safe, so you can wash up on a busy day or freeze small portions ahead of time. Keep the lid off if you want to put a pot in the oven, up to 200°C.
