Packing hot curry for delivery is not the same job as packing a cold salad or a ready-to-eat dessert. The heat, the moisture, the way the lid needs to hold - all of it changes depending on what's going into the box and how long it has to sit before someone opens it. Kitchens running a mixed menu know this well. Hot mains, cold sides, ready-to-serve extras - many end up testing two or three different container types before settling on one that actually handles all of it without constant complaints.
RE Series Containers exist for that exact reason. They're a food-grade container line built for everyday packing across hot, cold, and ready-to-serve categories, which is why restaurants, cloud kitchens, and caterers tend to reach for them instead of stocking a different container for every section of the menu.
RE Series Containers are rectangular, food-grade plastic containers made from polypropylene (PP 05). They're built for storing, packing, and transporting prepared food, and the range runs from smaller formats suited to single portions up to larger containers around 1250ML. Every size comes with a fitted lid meant to hold contents securely once the container is closed.
What makes the range work across temperatures is fairly simple - consistent wall thickness and a stackable shape that doesn't behave differently just because the food inside is hot instead of cold. A kitchen can pack a hot rice dish at lunch and a cold dessert box later the same day using the same container family, without switching product lines in between. Single-purpose packaging usually can't do that. It's built around one food type and tends to perform less predictably outside it.
Hot food puts real pressure on the lid. Pack hot curry or rice and seal the lid, and steam builds up inside almost immediately. If the seal isn't tight, that steam either escapes and the food goes lukewarm faster, or it condenses and drips back in, changing the texture by the time it reaches the customer. RE Series lids are built to sit snugly, which cuts down on this kind of moisture buildup over short transit windows.
Cold food runs into the opposite problem - condensation, caused by the temperature gap between the container and the air around it. This gets worse in summer deliveries. A flat lid surface, like the one on RE Series Containers, tends to manage this better than an irregular one, simply because there are fewer gaps for moisture to gather.
Ready-to-serve food is different again. Salads, snacks, portioned desserts - these are meant to be opened and eaten right away, so presentation and easy handling matter more than insulation. Here, what counts is a clear container, decent stacking, and a lid that opens without spilling.
Businesses handling all three on the same day tend to standardize on one or two RE Series sizes instead of juggling separate packaging for each. It's a small decision that makes order picking and stock management noticeably simpler, because staff aren't stopping mid-shift to figure out which container goes where.
Size isn't just about capacity. It's about matching the container to how a dish actually behaves once it's packed.
A few questions tend to settle this quickly:
Restaurants and cloud kitchens with a broader menu often keep a smaller RE Series size for sides and ready-to-serve items, and a larger one for mains, rather than forcing every dish through the same container.
Packing one order that has both hot and cold items in it is its own kind of headache, and no container fixes that entirely. But the right one takes a few problems off the table.
For businesses that also handle bulk orders - large catering events or supplying multiple outlets - it's common to pair RE Series Containers for individual dishes with RO Series Containers for bulk or family-style portions. The two ranges suit different order scales.
Using one container size for everything. It seems simpler, but it usually means overfilled lids on saucy mains and half-empty containers on sides - and both create their own handling problems.
Skipping the lid-stress test on hot food. Hot dishes build internal pressure, and a lid needs to hold that without warping or lifting. Businesses that don't check this ahead of time often find out the hard way, after a delivery complaint about a leak.
Forgetting about condensation on cold items. Chilled food generates moisture inside a sealed container, and for ready-to-serve items especially, that moisture affects how the food looks when it's opened.
Not planning reorders for multiple sizes. Stocking two or three RE Series sizes means tracking two or three reorder points. Skip that, and it's easy to run out of one size while sitting on plenty of another.
Ace Packaging has also written about the material and reusability side of RE Series Containers for businesses curious about the sustainability angle beyond day-to-day packing.
Ace Packaging manufactures RE Series Containers alongside a wider catalog that includes Deli Series Containers and Round Containers, so businesses can source different shapes and use cases from one supplier instead of several. A few reasons food businesses keep coming back:
If you're weighing up RE Series sizes, or comparing them against another range entirely, it's worth reaching out to the Ace Packaging team before placing a bulk order - sizing questions are usually easier to sort out over a quick conversation than through trial and error.
Getting hot, cold, and ready-to-serve packaging right comes down to matching the container to how the food actually behaves, not just how much it holds. RE Series Containers cover that range with a consistent, stackable design across sizes, so a kitchen can run one container family across a mixed menu instead of managing separate packaging for every temperature category. Before committing to a full bulk order, it's worth testing the size you're considering against real dishes - hot, cold, and ready-to-serve - to see how it actually holds up.
