Food Storage Containers Price Comparison 2026
Compare 215 food storage containers from Lock & Lock, ZWILLING and more — find the best price across top UK retailers, from 2 £ to 38 £.
Lock & Lock dominates this category like few brands dominate anything — 43 of the 215 products listed here carry that name, and their average price sits well below the market median. It's a telling signal: the Korean brand has essentially become the default choice for budget-conscious shoppers who want a reliable hermetic seal without overthinking it. But the story doesn't end there, and it's worth looking beyond the obvious.
What strikes us most when analysing this catalogue is the sheer spread. You'll find single containers starting from 2 £, and premium sets pushing up to 38 £ — a range that reflects genuinely different use cases rather than just brand inflation. At the lower end, polypropylene snap-lock boxes from Lock & Lock and Sistema handle everyday fridge storage perfectly well. Move up towards the median at 8 £ and you start encountering better materials: Tritan copolyester lids that resist staining, silicone gaskets that maintain their seal after hundreds of dishwasher cycles, and stackable designs that actually make a difference in a crowded fridge.
ZWILLING's Fresh & Save range sits at the premium end, averaging around 15 £, and it earns its price tag with vacuum-sealed technology that measurably extends food freshness. black+blum, with the highest average price in the catalogue, targets a different buyer entirely — one who cares as much about aesthetics as airtightness. For most households, though, the sweet spot sits firmly between 4 £ and 8 £, where brands like EMSA, OXO, and Sistema offer four-point locking systems and BPA-free materials without the premium markup.
One practical note worth making: rectangular containers consistently outperform round ones for fridge efficiency, simply because they tessellate without wasted space. If you're building a storage system from scratch, we'd recommend sticking to one brand's ecosystem — lid compatibility across sets from the same manufacturer is far more reliable than mixing and matching. For lunch boxes with leak-proof lids, or dedicated cake storage containers, we've got separate categories worth browsing. And if you're organising dry goods rather than leftovers, the kitchen storage containers section covers canisters and pantry solutions in more depth.
How to Choose the Right Food Storage Containers
Lock & Lock's dominance in this catalogue tells you something useful: most buyers prioritise a reliable seal and a low price over everything else. That's a reasonable starting point — but capacity, material, and compatibility with your appliances matter just as much once you're actually using these things daily. Here's what to focus on.
Seal quality and airtightness
This is the single most important factor. A container that doesn't seal properly is just a bowl with a lid. Look for a four-point locking system with a silicone gasket — the rubber ring you can see running around the inside of the lid. Lock & Lock's HPL range uses this mechanism reliably at a low price point. ZWILLING's Fresh & Save goes further with vacuum sealing, which is genuinely useful for marinated meats and soft fruit. Avoid containers where the lid simply press-fits without any locking mechanism; they'll leak in a bag and let air in overnight.
Material: plastic vs glass, and which plastic matters
Most containers in this catalogue are polypropylene (PP) — durable, microwave-safe, and light. That's fine for most uses. If you're storing acidic foods like tomato sauce or citrus regularly, consider Tritan copolyester, which resists staining and odour retention far better than standard PP. Borosilicate glass is the premium option: heavier, but it handles freezer-to-microwave transitions without thermal shock issues and never absorbs smells. All reputable brands here are BPA-free — but it's worth double-checking on cheaper, lesser-known units.
Capacity matched to your actual use
The range here spans from 0.18L (barely enough for a sauce portion) to 5.5L and beyond. For meal prep, 1–2L rectangular boxes are the workhorse size — they fit a standard portion of pasta or rice and stack neatly. A 0.6L round box is ideal for snacks or small leftovers. If you're batch cooking for a family, the 3.9L–5.5L Lock & Lock HPL boxes offer excellent value. Buying a set with mixed sizes is usually smarter than buying multiples of one size — you'll use the variety more than you expect.
Fridge and freezer geometry: rectangular wins
Rectangular containers use fridge space roughly 30% more efficiently than round ones of equivalent volume — they simply don't leave triangular dead zones. If your fridge is tight, this matters. Stackable designs with interlocking edges (common in the Lock & Lock HPL range and EMSA's lineup) let you build vertical columns without containers sliding. Nesting capability — where empty containers fit inside each other — is worth prioritising if cupboard space is limited.
Dishwasher and microwave compatibility
Most PP containers in this catalogue are dishwasher-safe on the top rack and microwave-safe with the lid removed. The distinction matters: some lids with metal clips or certain gasket materials degrade faster in dishwashers. ZWILLING and OXO are explicit about full dishwasher compatibility across lid and base. If you regularly reheat directly in the container, confirm microwave-safe status — it's usually marked on the base with a microwave symbol. Oven-safe containers are rarer and typically require borosilicate glass construction.
Value per litre, not value per unit
A container priced at 2 £ sounds like a bargain until you notice it holds 0.18L. Thinking in cost-per-litre quickly reveals which products offer genuine value. Lock & Lock's larger HPL boxes (3.9L–5.5L) are among the best value-per-litre options in the catalogue. At the other end, premium sets from ZWILLING or black+blum cost significantly more per litre — but if vacuum sealing or aesthetics matter to you, that premium has a rational basis. For pure storage efficiency on a budget, the mid-range Lock & Lock and Sistema options are hard to beat.
- Budget picks (From 2 £ to 4 £) : Lock & Lock's smaller snap-lock boxes dominate this tier — reliable four-point seals, BPA-free polypropylene, and multiple sizes available. Sistema also appears here with its clip-top range. Ideal for students, single-person households, or anyone building a basic set without spending much. Don't expect premium aesthetics or vacuum sealing, but the core function — keeping food fresh — is delivered competently.
- The sweet spot (From 4 £ to 8 £) : This is where the catalogue gets interesting. Lock & Lock's larger HPL boxes (2L–5.5L), Sistema multi-packs, and entry-level EMSA containers all sit here. You get better stackability, more size variety, and often improved gasket quality. Most buyers building a complete fridge storage system will find everything they need in this range. Excellent value-per-litre territory.
- Mid-range quality step-up (From 8 £ to 15 £) : OXO, Rotho, and EMSA feature prominently here, alongside Tower's Cavaletto canisters. Materials improve noticeably — Tritan copolyester, better-engineered lids, and more considered stackable designs. ZWILLING's entry-level Fresh & Save sets appear at the top of this band. A good choice if you're replacing a mismatched collection with something coherent and durable.
- Premium and specialist (Over 15 £) : ZWILLING Fresh & Save vacuum sets and black+blum's design-led containers occupy this space. The vacuum sealing technology in ZWILLING's range is genuinely useful for extending freshness beyond what standard airtight lids achieve. black+blum appeals to buyers who want their kitchen storage to look as considered as the rest of their kitchen. CARLISLE's professional-grade containers also appear here, built for durability over aesthetics. Worth it if you have specific needs — overkill if you just want to store leftovers.
Top products
- Lock & Lock HPL819 Rectangular Box 2 L Transparent 1 pc(s) (Lock & Lock) : The most-listed container in the catalogue for good reason — 2L is the ideal everyday size, the four-point seal is reliable, and the price is hard to argue with. Not the most durable plastic long-term, but exceptional value for the money.
- Lock & Lock HPL836 food storage container Rectangular Box 5.5 L Blue, Transparent 1 pc(s) (Lock & Lock) : Best value-per-litre in the entire catalogue. At 5.5L, this is the go-to for batch cooking and bulk storage. The blue lid aids quick identification in a stacked fridge. Slightly bulky for smaller fridges, but if you meal prep, this earns its place.
- Lock & Lock HPL933 food storage container Round Box 0.6 L Transparent 1 pc(s) (Lock & Lock) : A compact round box that's genuinely useful for sauces, snacks, and small portions. Round containers are easier to clean than rectangular ones, and at this price it's a low-risk addition to any storage set. Don't expect it to stack efficiently though.
- ZWILLING FRESH & SAVE Rectangular Box Grey, Transparent 3 pc(s) (ZWILLING) : The premium pick. Vacuum sealing technology puts this in a different league for extending food freshness — particularly useful for marinated proteins and soft produce. A three-piece set justifies the higher price if you cook seriously. Overkill for basic leftover storage.
- Tower Cavaletto Round Canister 1.3 L Blue 3 pc(s) (Tower) : The aesthetic outlier in this catalogue — the Cavaletto set prioritises looks as much as function, and it shows. A solid choice for countertop dry storage where you want something presentable. Less suited to fridge stacking than rectangular alternatives.

Frequently Asked Questions
What's the difference between airtight and leak-proof food storage containers?
Airtight means no air passes through the seal; leak-proof means liquids won't escape during transport — and the two aren't the same thing. A container can be airtight (good for keeping food fresh in the fridge) without being leak-proof when tilted or carried in a bag. Lock & Lock's four-point locking system with silicone gasket achieves both, which is why it's so widely recommended. If you're packing soups or sauces for lunch, check specifically for leak-proof certification rather than just assuming airtight covers it.
Are Lock & Lock containers actually worth buying, or is the brand overhyped?
Lock & Lock is genuinely one of the best value-for-money options in this category — the hype is largely justified. Their four-point locking mechanism with silicone gasket delivers reliable airtightness at a price point that undercuts most competitors significantly. The polypropylene construction is BPA-free and dishwasher-safe. Where they fall short is odour retention over time — after a year of storing strong-smelling foods, some PP containers absorb smells that don't fully wash out. If that's a concern, step up to Tritan copolyester or glass.
Can I put food storage containers in the microwave with the lid on?
Almost never — and doing so with a sealed lid can cause pressure build-up and warping, or even cracking. Most microwave-safe containers require the lid to be removed or at least vented before heating. Some lids have a small vent tab for exactly this purpose. Check the base of the container for the microwave-safe symbol (wavy lines), and always follow the manufacturer's guidance on lid removal. ZWILLING and OXO both provide clear guidance on this in their product documentation.
What size food storage containers should I buy for meal prep?
For most meal prep needs, a mix of 1L and 2L rectangular containers covers the majority of use cases. A 1L box holds a standard single-portion meal; 2L suits larger portions or side dishes. Add one or two 0.6L round boxes for snacks and sauces, and a 3.9L–5.5L box for batch-cooked grains or soups. Buying a set with mixed sizes from a single brand ensures lid compatibility and consistent stackability — far more practical than buying individual units across different brands.
Is it worth paying more for glass food storage containers over plastic?
Glass is worth the premium if you regularly reheat food in the container or store strongly flavoured foods like curries and tomato-based dishes. Borosilicate glass doesn't absorb odours or stains, handles freezer-to-oven transitions without thermal shock, and lasts significantly longer than plastic. The trade-offs are weight and breakage risk. For packed lunches or portable storage, plastic is more practical. For home fridge and oven use, glass pays for itself over time — especially if you've ever had to throw out a stained plastic container.
Which food storage containers are best for the freezer?
Look specifically for containers rated to at least -20°C with lids that maintain their seal at low temperatures — not all plastics do. Lock & Lock's HPL range and Sistema's clip-top containers are both freezer-safe and maintain their four-point seal when cold. Avoid containers with thin, press-fit lids — the plastic contracts in the freezer and the seal fails. Leave a small gap at the top of the container when freezing liquids, as expansion can crack even well-made containers if filled to the brim.
What's the trap to avoid when buying food storage container sets online?
The most common mistake is buying a large set of identical-sized containers — you'll use three of them constantly and the rest will gather dust. Sets that look impressive in photos often include six or eight containers of the same volume, which sounds like value but isn't. Prioritise sets with varied capacities. Also watch out for containers where the lid count doesn't match the base count — a surprisingly common issue with budget multi-packs. Finally, check whether replacement lids are available to buy separately; a container is useless once its lid cracks, and not all brands sell spares.
