If you’re a commercial kitchen manager, catering business owner, or even a home baker who’s ever struggled to lift a stack of damp, heavy plastic drying trays—especially one loaded with cooling cookie sheets, washed produce, or freshly laundered dishware—you know that flimsy, curved tray edges just don’t cut it. As a plastic drying tray supplier, I’ve heard this complaint so many times over the years that I stopped viewing it as a customer request and started seeing it as a design flaw we could fix for good. Plastic Drying Tray
I’m Jake, and for the past seven years, I’ve ran the small plastic manufacturing line that produces our line of commercial-grade drying trays. We don’t do cheap, flimsy plastic here—our trays are made from BPA-free polypropylene, rated to hold up to 120 pounds of evenly distributed weight, and designed to withstand 1,000+ cycles in commercial dishwashers. But even the best tray is useless if you can’t move it without straining your back or spilling half its load. That’s why I’ve spent the last two years testing every possible way to add a handle to our trays, from simple DIY fixes to industrial-grade modifications that work for our full catalog.
Now, before we dive in, let’s get one thing straight: adding a handle to a plastic drying tray isn’t just drilling a hole and jamming a stick in it. If you skip the science, you’ll end up with a handle that snaps mid-lift, leaks water all over your storage area, or creates sharp edges that can cut hands or damage dishware. Over my testing, I’ve found that the best method depends on two things: whether you’re modifying an existing tray in the field, or integrating a handle into a new tray during manufacturing. I’ll break both down, plus share the mistakes I made along the way so you don’t repeat them.
First, let’s talk about the core principles that make a good tray handle. A handle needs three non-negotiable things: it has to distribute weight evenly so you don’t put stress on one small spot of the tray, it has to be sealed so water and grime can’t get trapped between the handle and the tray (which causes mold, mildew, or handle detachment over time), and it has to be sized for comfort—no handles so big they hang over the edge of a standard storage rack, and no handles so small they cut into your palm when you’re lifting a full tray.
When I first started testing, I tried a simple DIY method: drill two ¼-inch holes on the upper rim of the tray, slide a plastic rod through, and glue it in place. That worked for light loads, but when we tested it with a full tray of stainless steel mixing bowls, the glue gave out in three days. Why? Because polypropylene, the plastic we use, is a non-porous polymer. Most glues don’t bond well to it—they just sit on the surface, and when the tray expands and contracts with temperature changes (from cold dish soap to hot drying cycles), the glue cracks. I also tried adding metal screw inserts, but those also failed because the plastic around the hole would crack under pressure, especially if the tray was bumped around in a commercial dishwasher.
After 17 failed prototypes, I landed on two methods that work, both rooted in material science and tested for real-world use. The first is our go-to for manufacturing new trays—integrated molded handles, and the second is a field-modified handle for trays that are already in use and need a boost.
Let’s start with the manufacturing method, because that’s what sets our trays apart from cheaper competitors. When we design a new tray, we don’t just cut a sheet of plastic and add a handle as an afterthought. We modify the tray’s rim during the injection molding process, which is the method we use to make all our trays (it’s the most reliable for commercial plastic parts). Here’s how that works, step by step, and why it’s durable:
First, we adjust the tray’s upper rim to be ¼-inch thick, instead of the standard 1/8-inch for budget trays. That extra thickness gives us enough material to form a solid, integrated handle without compromising the tray’s load capacity. During the injection molding process, we use a dual-cavity mold—one half forms the main tray body, the other forms the handle and the notch that locks it into the rim. The key here is that the handle is not a separate piece; it’s one continuous part of the tray, molded at the same time as the base. That means there’s no seam, no glue, no point where water can get trapped, and the handle is rated to hold 25 pounds on its own (which is more than enough, since a full tray only weighs around 15 pounds total when loaded).
We also made a small design tweak to the handle shape to make it more functional. Instead of a straight bar, we made it slightly curved, with a 2-inch grip area—big enough to fit two fingers, small enough to not hang over the edge of our standard 20×26-inch tray (the most popular size for commercial kitchens). We also added a ½-inch lip on each end of the handle that locks into the tray’s rim. That lip acts like a guard, so when you lift the tray, the force is distributed along the entire rim, not just the connection points. I tested this by hanging a 50-pound weight from the handle for 72 hours straight, and the tray didn’t bend, the handle didn’t pull out, and there was no warping in the plastic. That’s way more reliable than any glued or screwed-on handle.
Now, what if you already have a set of our trays (or any compatible plastic drying trays) and want to add a handle without sending them back to the factory? We get this request all the time from small cafes or home bakers who don’t want to replace their existing trays. So we developed a field-modified handle system that’s easy to install, no special tools needed, and durable enough for commercial use. Here’s how that works, based on my testing:
First, you need the right parts. We sell these handle kits direct, so you don’t have to guess at sizes. Each kit comes with two reinforced plastic mounting brackets, a food-grade plastic handle rod, and a tube of polypropylene-compatible adhesive that’s designed specifically for the type of plastic we use in our trays (it’s not regular super glue—regular super glue breaks down in hot water, which is a problem for commercial dishware). The brackets are made from the same BPA-free polypropylene as the tray, so they expand and contract at the same rate, which prevents cracking.
The installation steps are simple, and I’ve had new hires at my factory test this in less than 10 minutes per tray. First, you need to prep the mounting area on the tray’s rim. This is the most important step, because if you don’t do this right, the adhesive will fail. Take a piece of 200-grit sandpaper, and rough up a 2×2-inch area on the upper inner rim of the tray, on both sides where you want to mount the brackets. Don’t skip this—polypropylene is slippery, and the sanding creates a porous surface that the adhesive can bond to. Next, wipe the area with isopropyl alcohol to remove any dust, oil, or residue (even the natural oils from your fingers can prevent the adhesive from sticking). Let that dry completely—adhesive doesn’t work well on damp surfaces.
Once the area is prepped, apply a thin, even layer of the polypropylene adhesive to the back of each mounting bracket, then press them firmly to the sanded area of the tray. Hold each bracket in place for 30 seconds, then clamp them with a small C-clamp or even a pair of pliers wrapped in tape (so you don’t scratch the tray) and let them cure for 24 hours. That’s the waiting game—rushing this step is how you end up with a handle that falls off. After 24 hours, just slide the plastic handle rod into the pre-molded notches on the brackets, and you’re done.
I tested this field method on 15 trays that we sold to a small bakery in Portland two years ago. Last month, I did a follow-up call with their head baker, Maria, and she told me those handles are still on every tray, and they haven’t had to reattach a single one. The only thing she mentioned is that they clean the brackets by hand occasionally, because dishwasher cycles can wear the adhesive a tiny bit over 18 months—so we now add a small packet of extra adhesive with every kit, just in case.
But wait—before you go drilling or gluing anything, I want to share the mistakes I made so you don’t waste time or money. First, never use metal handles on our plastic trays, especially for commercial use. Metal handles conduct heat, so when you put a hot tray right out of the oven under a heat lamp, the handle gets too hot to hold, and it can also scratch the tray or the dishware. Second, never use cheap, generic glue. Most all-purpose adhesives (like Gorilla Glue) don’t bond well to polypropylene, and they break down in temperatures over 140 degrees, which is standard for commercial dishwashers. Third, don’t mount the handle on the front rim of the tray, right over the drainage holes. I did that in one test, and when I lifted a full tray, water pooled around the handle’s connection, causing the plastic to warp slightly after a month. Mount the handle on the back rim, where the drainage holes are minimal, so water can flow freely without pooling.
As a supplier, my goal isn’t just to sell you a tray—it’s to sell you a solution that works for your space, your budget, and your needs. We’ve had customers who run 100-seat restaurants buy our integrated handle trays for their dishwashing stations, and small home bakers who buy our field handle kits for their home counters. The integrated handles are more expensive upfront, but they last the life of the tray (we offer a 5-year warranty on all our trays, and the handles are part of that). The field kits are cheaper for people who already have trays, and they’re easy to swap if you ever need to move them to a different tray later.
If you’re still not sure which method is right for you, or if you have questions about the handle kits, tray sizes, or warranty details, feel free to reach out. We don’t have a fancy sales team—just a small group of people who use these trays every day, because we’re the ones designing, testing, and shipping them. We work with kitchens of all sizes, from tiny cafes to large catering companies, and we can help you pick the right size and handle type for your specific needs.
At the end of the day, a plastic drying tray is a workhorse. It holds your food, your dishware, your small kitchen tools, and it gets used dozens of times a day. Adding a good handle isn’t just a convenience—it’s a way to make that workhorse more efficient, safer, and easier to use. We’ve spent years perfecting this, and we know it works because we use our own products in our factory’s kitchen every single day.
