Melamine is a coating, not a material. It’s a thin decorative surface: paper soaked in melamine resin and fused under heat and pressure onto a core board. That core can be particleboard, MDF or plywood, and the core, not the melamine, decides how melamine cabinets handle water, screws and weight.
That’s the part most “melamine vs plywood” articles skip. When people say “melamine cabinets,” they usually mean melamine-faced particleboard, the most common and most affordable version. In the video below, I compare that board with plywood, the two materials most cabinet boxes are built from, wherever you buy them. The box means the back, the side (gable) panels and the toe kick: the parts you don’t look at every day but that do the actual work.
In the videos, “melamine” means melamine-coated particleboard, the most common type.
Quick note: in the video we say the coating is glued on. Melamine is actually fused onto the board with heat and pressure.
TL;DR – Quick Summary
- Melamine is the surface. Whenever you see it on a quote, ask: melamine on what?
- Most melamine kitchen cabinets are melamine-faced particleboard. It’s affordable, wipe-clean and fine in dry rooms.
- The weak point is the particleboard core, not the melamine. It swells for good once water reaches it, and screws loosen over time.
- Plywood isn’t waterproof, but in our soak test it went back to normal while the particleboard stayed swollen.
- Our cabinets are full plywood construction, with no melamine.
Melamine Is the Finish, the Core Is What Matters
Melamine resin is a hard, durable thermoset plastic. Decorative paper is soaked in it and bonded to a board under heat and pressure, and the trade calls the result thermally fused laminate (TFL) or low-pressure laminate. It comes in almost any colour you can think of (white, grey, blue, even pink), plus wood-look prints. The surface is wipe-clean and needs no finishing.
So is melamine just plastic? The surface is a plastic resin, but in a cabinet it’s only a thin, cured layer fused to the board. It’s the same resin family as melamine dishes, which is why a search for “what is melamine” turns up food-safety pages, but a cabinet panel is a different product.
What sits underneath is a separate choice, and it changes almost everything:
| Melamine on… | What the core is | Where you’ll usually see it |
|---|---|---|
| Particleboard | Wood chips and sawdust bonded with resin. Heaviest and least water-tolerant of the three | The most common type. Budget and big-box cabinets, closets, flat-pack furniture |
| MDF | Fine wood fibres pressed into a dense, smooth board | Shelving, panels and some cabinet parts where a smooth, flat surface matters |
| Plywood | Cross-laminated layers of real wood veneer. Lighter, stronger and more forgiving of water | Boxes that want a wipe-clean surface on a sturdier core |
So melamine isn’t good or bad on its own. A melamine surface on particleboard behaves like particleboard, and the same surface on a sturdier core behaves like that core. Whenever you see “melamine” on a quote or spec sheet, ask one question: melamine on what?
One more surface detail: a cut edge of any melamine board isn’t covered, so exposed edges get edge banding, a thin strip glued or heat-applied along the cut. Remember that. It matters once water shows up.
Names You’ll See on a Quote
Quotes and spec sheets rarely say “melamine-faced particleboard” in plain words. Here’s what the common names mean. (In Canada you’ll also hear “melamine kitchen cupboards.” Same thing.)
| Name on the quote | What it actually is | Core underneath |
|---|---|---|
| Melamine / melamine board / melamine panel | A melamine surface on a board | Usually particleboard, sometimes MDF. Ask |
| TFL (thermally fused laminate) | The trade name for melamine: resin-soaked décor paper fused straight onto the board, with no glue line | Particleboard or MDF |
| TFM (thermally fused melamine) | An older name for TFL | Particleboard or MDF |
| LPL / LPM (low-pressure laminate / low-pressure melamine) | The same family as TFL | Particleboard or MDF |
| MFC (melamine-faced chipboard) | The UK and European name for melamine on particleboard | Particleboard |
| Melamine-faced or melamine-coated particleboard | The spelled-out North American version of MFC | Particleboard |
| Chipboard | Another name for particleboard | It is the core |
| Furniture board / industrial particleboard | A denser, cabinet-grade particleboard. Still particleboard | It is the core |
| Pressboard | An informal name for particleboard | It is the core |
| Engineered wood / composite wood | Umbrella terms that cover particleboard, MDF, HDF, OSB and plywood. On their own they tell you nothing | Ask which one |
One caution: some retail “melamine” is a lightweight paper glued onto the board rather than thermally fused. It’s the same name for a lesser product, so it’s worth asking how the surface is applied. If you’re weighing a big-box flat-pack, we’ve compared IKEA kitchen cabinets with ours box by box.
Melamine vs Thermofoil vs Laminate
These three get lumped together, but they’re made differently and fail differently.
| Surface | What it is | Where you’ll see it | Key difference |
|---|---|---|---|
| Melamine (low-pressure laminate) | Resin-soaked paper fused directly to the board under heat and pressure | Cabinet boxes, shelving, closets, some doors | Thin and fused on. Exposed edges need banding, and the core decides how it handles water |
| High-pressure laminate (HPL), e.g. Formica or Wilsonart | Layers of kraft paper and resin pressed at very high pressure (over 1,400 psi) into a sheet, then glued to a core | Countertops and hard-wearing surfaces | Tougher than melamine. It’s a separate sheet glued on, not fused |
| Thermofoil (RTF, 3DL) | A vinyl (PVC) film heated and vacuum-formed over an MDF door | Doors | Wraps the edges, but heat and moisture can make it lift or peel, and peeling usually can’t be repaired |
So is melamine just laminate? Yes, a low-pressure kind. If a quote says “laminate” with no detail, ask whether it means melamine or HPL. For more on doors, see our comparison of thermofoil vs painted cabinet doors, or watch our video on how thermofoil and painted doors handle moisture.
What Plywood Is
Plywood is thin layers of real wood veneer stacked on top of each other, with each layer running perpendicular to the one before it. It’s always made with an odd number of layers, which helps with strength and balance. Stacking the grain crosswise makes a strong panel that’s much less prone to warping than a solid board with all its grain running one way.
Plywood can be clear-coated, painted or melamine-faced. In the video, I hold up a maple-look melamine-faced particleboard panel next to real maple plywood under a clear top coat. To the touch and at a quick glance they’re very similar. Unless you see an exposed edge or side panel, it’s hard to tell which core you’re looking at.

Melamine vs Plywood: It’s Really Particle Board vs Plywood
When people compare “melamine vs plywood,” they’re really comparing two cores: particleboard (usually melamine-faced) and plywood. Here’s the general pattern. Products vary by manufacturer, thickness and grade, so treat it as a guide, not a promise about every brand.
| Particleboard (usually melamine-faced) | Plywood | |
|---|---|---|
| What it is | Wood chips and resin pressed into a board, usually with a melamine surface | Cross-laminated layers of real wood veneer, odd number of plies |
| Surface and cleaning | With a melamine face: smooth, wipe-clean, huge colour range | Clear-coated wood grain, paint or melamine; cleans well once sealed or faced |
| Moisture | The melamine face resists water, but once water reaches the particleboard core through an edge, screw hole or chip, the core swells and usually stays swollen | Not waterproof, but far more forgiving. It sheds small amounts of water and tends to return close to its original size |
| Screw holding | Easier to over-tighten a screw so it just spins; screws can work loose over time | Grips screws for the box, hinges and drawer slides, and doesn’t let go easily |
| Weight | Heavier for the same thickness | Lighter for the same thickness, so easier to carry, assemble and hang |
| Edges | Needs edge banding, which can chip or peel; the board can chip when cut or knocked | Layered edges; often hidden behind a face frame |
| Repair | A damaged melamine face can be painted over but not refinished; a swollen core can’t be fixed | A clear-coated plywood face can be sanded and refinished |
| Cost | Lower. Its biggest advantage | Higher for the same box size |
Are Melamine Cabinets Good? Where They Do Well
Melamine and particle board cabinets get a rough ride online, and some of that’s unfair. Melamine-faced particleboard does a few things well:
- Price. It’s one of the most affordable ways to build a cabinet box. As I put it in the video, it’s “really just a cost thing,” and sometimes cost is what matters most.
- Easy-clean surfaces. The melamine face wipes clean in seconds and never needs refinishing. That’s true of a melamine face on any core.
- Dry spaces. In a closet, office or dry storage area, the particleboard core’s weak spots rarely come into play. A laundry room sits in between: dry most days, but a washer can leak, so treat it more like a kitchen.
You may hear a salesperson say melamine is “more durable.” That’s true of the surface: it’s hard and scratch-resistant. It isn’t true of the particleboard core underneath, which is where melamine cabinets usually fail.
If the budget is tight and the cabinet will live somewhere dry, melamine-faced particleboard can be a sensible choice.
Screws, Hinges and Drawer Slides
The first place you notice the difference isn’t the surface, it’s the screws. Every hinge, drawer slide and box joint depends on the core the screw is driven into.
Plywood’s cross-grain layers grab a screw and don’t let go easily. In a particleboard core it’s much easier to over-tighten, so the screw just spins in its hole. Over years of doors opening and drawers sliding, screws in particleboard also tend to back out and loosen. That’s why a sagging door or a wobbly slide is so often the first sign of trouble in a particleboard kitchen. For a filmed comparison, watch our hinge pull test on an IKEA cabinet and a plywood RTA cabinet.
What Happens When Particleboard Gets Wet
This is the big one. In the video below, we cut melamine-faced particleboard and plywood samples and put them in water, then checked them as they dried. The melamine face wasn’t what failed. It was the particleboard core underneath.
In the videos, “melamine” means melamine-coated particleboard, the most common type.
Here’s what we saw:
- One hour in water, then 48 hours to dry.
- The plywood was very slightly swollen at the edges where water got in, then went right back to normal: maybe a 1/32″ difference and no delamination.
- The melamine-faced particleboard shrank a little as it dried but stayed almost 1/8″ thicker than an unsoaked piece. Its edges flaked, and the layers of the particleboard core started to separate. We could tear off big chunks by hand.
- Overnight, just over 12 hours.
- The particleboard sample swelled by roughly 3/16″ and crumbled when we brushed the corner with a fingernail, with a crack forming down the middle.
- The plywood was discoloured around the edges but swollen by maybe 1/32″ to 1/16″, with no delamination we could find.
- Half in, half out. We stood one particleboard sample with only its bottom half in the water for about an hour to an hour and a half. The swelling crept well above the waterline: the particleboard core acted like a candle wick, or a sponge, pulling moisture up into the panel.
That last test matters most in a real kitchen. A particleboard core doesn’t just fail at the wet edge, because it pulls moisture into the rest of the panel. As Lewis put it in the video: “When it gets dried out, that’s where a lot of the… issues happen. Kind of think of it like a freeze thaw cycle where… your garden hose freezes and expands and… blows the garden hose apart.” The core swells, never fully shrinks back, and starts to separate.
You’re probably not going to soak your cabinets, and a water bath is a harsher, faster version of real life. But think about the everyday version: a wet mop brushing the bottom of the cabinets, the cabinet beside the dishwasher getting steamed every cycle, a slow drip under the sink, or steam from a boiling pot rising into your wall cabinets. Each wet-dry cycle is a small version of that test.
To be fair, these were our own informal tests in the shop, not a lab study, and no cabinet material is waterproof. Plywood can also stain or delaminate if it sits in water long enough. The point is how the two cores fail: plywood is forgiving of the occasional spill, while particleboard tends to swell for good once water reaches it. For more on moisture and the tough Maritime climate, see most durable kitchen cabinets.
Impact, Repairs and How Long They Last
Water isn’t the only test we’ve run. In our kitchen cabinet hammer test, a big-box cabinet built from 3/4″ melamine-coated particleboard failed after absorbing about 586 joules of impact. Our plywood cabinet was still standing past 3,500 joules. That was another filmed demonstration of ours, not a lab result, but it shows the same pattern: the particleboard cracked through its core, while the plywood only began separating at the glue lines. You can watch the full hammer test on YouTube.
Then there’s the long view. Plenty of 1970s plywood kitchens are still in use and get replaced for their style, not because the boxes failed. Many melamine-faced particleboard kitchens from the late ’90s and early 2000s are already being replaced.
What BluePrint Cabinets’ Boxes Are Made Of
We sell ready-to-assemble (RTA) cabinets, and, as I say in the video, “all of our cabinetry are actually full plywood construction.” Some suppliers use plywood only at the sink and dishwasher and particleboard everywhere else. Our cabinets are plywood throughout:
- Box: 5/8″ plywood sides and a full 5/8″ plywood back, with an AA face-grade veneer on the show surface. The bottoms and shelves are plywood too.
- Interiors: clear-coated plywood. There’s no melamine anywhere in our cabinets.
- Face frame: 3/4″ solid birch.
- Joinery: the face frame locks to the box with a sliding dovetail backed by metal corner brackets. No cam locks.
- Toe kick: solid plywood to the floor, not plastic legs.
- Drawers: solid wood drawer boxes with dovetailed corners, on full-extension soft-close slides.
- Painted doors: HDF on purpose. Real wood expands and shrinks with the seasons, which opens hairline gaps in a paint film. HDF barely moves, so the paint stays intact.
- Hardware: soft-close hinges and slides on every cabinet, with a lifetime warranty on hardware and a one-year warranty on everything else.
Because every cabinet from BluePrint Cabinets is framed (here’s how framed and frameless cabinets differ), the front edges of the box sit behind solid birch rather than edge banding. For the full picture of how an RTA cabinet goes together, start with what are RTA cabinets. You can see the door styles that go on these boxes on our shaker cabinets page. To compare these specs side by side, or to order online, use the cabinet comparison in our online shop. And if you’re wondering where our cabinets are made, that page explains why the materials matter more than the country.
“The install of our BluePrint kitchen cabinets was completed just this week. The cabinets are high quality with plywood boxes, a nice finish, and soft-close hinges and drawer glides. BluePrint was very helpful with the design process and had clear and timely communication with us through the ordering, shipping, and installation process. Thanks to Patrick and John for all their help!”

Which Should You Choose?
Start by asking what the core is, then decide. As we say at the end of the water video: you decide. For the other questions to ask, use our checklist for choosing kitchen cabinets.
Melamine-faced particleboard is likely the right fit if:
- the cabinets are going somewhere dry, like a closet, office or storage room
- you’re furnishing a rental or a flip and the lowest upfront cost matters most
- you love a bright, uniform, wipe-clean surface and will be careful around water
A plywood box is likely the right fit if:
- the cabinets are going in a kitchen or bathroom, especially around the sink, dishwasher and stove
- you plan to stay for years and want the boxes to outlast the next style change
- you’re hanging heavy wall cabinets or expect to adjust hinges and slides over time
- you’re assembling RTA cabinets yourself and want boxes that are lighter to handle and hold a screw
A full RTA kitchen from BluePrint Cabinets usually lands between $5,000 and $25,000 CAD plus HST, or roughly $350 to $700 per linear foot, and orders typically arrive in 2 to 4 weeks. We publish real layouts on our kitchen pricing page so you can compare like for like. And if a particleboard box really is the better call for your project, we’ll tell you.
