Food-grade silicone can release siloxanes such as octamethylcyclotetrasiloxane (D4) over time. Some siloxanes, D4 among them, are classified by the EU's chemicals agency as Substances of Very High Concern - very persistent and very bioaccumulative.
Plastic isn't always inert. Certain plastics can leach their softening additives and shed microscopic particles into food - more so with heat, oil, acidity and age. You already knew this; it's why you tried to avoid plastic, and you were right.
Silicone feels like the safe escape, so few people question it. But it's synthetic too, and it can release siloxanes over time - and some, like D4, the EU classifies as substances of very high concern. The amounts may be small, but it's a strange thing to leave unchecked on the surface that closes over your food every day.
Silicone is the same story as plastic at the end: it doesn't biodegrade, and household recycling won't take it. So it persists in the environment for generations to come — exactly like the plastic you're leaving behind.
The container that should exist
A container where the only thing that ever touches your food is 304 stainless steel — body and lid. No gasket, no liner, no coating, no soft octamethylcyclotetrasiloxane shedding silicone hiding in the rim. Nothing to shed, nothing to degrade, nothing hidden.
Four all-steel boxes in two sizes, sized by a hearty home portion. A true usable litre size are the real capacity. Most brands print a nominal, calculated figure that's larger than the box actually holds.
Each 1.0 Litre is about two hearty servings of one dish — a curry or chilli for two, or one full meal.
The 1.6 Litre is about three hearty servings ideal for bulk cooking & storages.
A secure & tight lid
The steel lid is shaped to grip the rim and lock on tight — a mechanical friction fit, no gasket, no clips, just steel on steel. It's secure and snug: laid flat it stays securely sealed, and it stays put through the fridge, freezer and a packed cupboard. Not fully airtight, so not for carrying liquids loose in a bag — but for home storage it holds firm, and dry food travels fine.
Built for the way you bulk-cook
Bulk cooking means a tower of tubs and a drawer of orphan lids. Loopware nests both ways — same size into same size, and the 1.0L down inside the 1.6L — so the whole set collapses to one footprint. Empty, they tuck away; full, they stack flat in the fridge and freezer — neat and tidy.
Out of the freezer
It can take forever to prise a frozen block out of a glass container — waiting, chipping, running it under water forever. Steel carries warmth fast, so a few seconds under the tap and the whole block drops straight out. Sounds trivial — unless you batch-cook. Then you know it isn't.
More reliable than see-through
Stainless steel containers label easily. Paper tape names the dish and date and works every time; a wax crayon is the low-waste choice, though it takes a dab of cooking oil on a towel to wipe off.
The one thing it won't do
Steel reflects microwaves — so the food heats unevenly, the energy bounces back at the oven, and a dent or sharp edge can even spark. It's simply not what steel is for. Reheat on the hob or in the oven instead — that's where this material shines.
A tip for your routine
Most people never think to put a steel box on the hob or into the oven — but Loopware is built robust for exactly that. Rediscover it as the backbone of your busy-week meal prep.
Glass vs Loopware
We say what's tested and verifiable
We sent the containers to an independent lab and put them through the tests that matter to food safety.
Report No.: CANEC26009066101
Tested under hot, acidic conditions for four hours, every heavy metal screened - aluminium, antimony, arsenic, barium, beryllium, cadmium, chromium, cobalt, copper, iron, lead, lithium, manganese, mercury, molybdenum, nickel, silver, thallium, tin, vanadium, zinc and zirconium - came back Not Detected.
Report No.: DGP26-000531
304 (18/8) is the prime food-safe stainless steel used in the kitchen — and an independent lab confirmed it's exactly what this container is made from. The full alloy composition was analysed and came back at 18.2% chromium, 8.0% nickel.
Questions & Answers
No - it's stainless steel, and steel reflects microwaves. Other brands might claim microwave-safe, but the nature of this material simply isn't suited to it. Reheat on the hob or in the oven instead; that's where it's at its best.
It's a mechanical friction-fit: the steel lid grips the rim, steel on steel. No clips to snap, no silicone seal to warp, mould or go missing.
No. Non-porous steel doesn't soak up colour or odour the way plastic does, and there's no silicone seal in the food path to trap grime - so no orange curry stains or smells that never quite wash out. This doesn't mean there's no chance a stain might stay on the stainless steel, but the situation is a world away from the experience you can get from plastic.
It's built for home - fridge, freezer and kitchen handling. Laid flat it stays securely sealed, but it isn't airtight, so it's not for carrying soup or other liquid loose in a bag. Dry food travels fine.
For everyday use, yes - keeping tomato, curry or salty leftovers in the fridge or freezer is exactly what it's built for. At those low temperatures metal migration is negligible; the concerns you may have read about come from cooking acidic food in steel at high heat for hours, which is a different thing from cold storage. Our migration test was run under hot, acidic conditions with nothing detected - so storing all type of foods is well within safety margins.
Since it's opaque, a quick label saves the guesswork. Paper tape is the most reliable - write the dish and date, and it peels off in the wash. A wax pencil is the lower-waste choice, though it takes a dab of cooking oil on a towel to wipe off. Either way, nothing gets lost at the back of the fridge.
Loopware is a brand based in London. Its mission is to use endlessly-recyclable materials - like stainless steel, which can be recycled again and again without losing quality - to replace wasteful, unsustainable products wherever that makes sense in everyday living.
Yes, we are. The company behind Loopware is Palm & Pine Living Limited (company number 16983434), based in London. This stainless steel food container is made in China to our own specification, then independently lab-tested before it reaches you.
The Neat Solution Set is 3 x 1.0L plus 1 x 1.6L for £69.99 - that's £19.99 off buying them separately. The batch is already made and shipped; estimated delivery to you by mid-August. This founding run is a limited quantity - if what you see is 'join the waitlist', the founding sets are all claimed; the waitlist is filled from the next batch, and its timing depends on that batch's delivery date.

Already made. Already shipping.
This isn't a concept waiting on a factory. The founding batch is finished, boxed, and has already left for the UK - expected to land by the end of July, with delivery to you by mid-August. Your £5 deposit reserves a set that already exists, not a project we're still hoping to build.
