Can I customize the colors of PP woven bags?

When I first started working at my family’s PP woven bag supply business back in 2008, I could count the number of custom color requests we got on one hand. Back then, most clients wanted plain white or natural beige bags for general packaging, and if they wanted a little extra flair, they’d ask for a basic black print—nothing too bold, nothing too specific. Fast forward to 2024, and I lose count of how many times I get this question: “Can I customize the colors of PP woven bags?” Colorful PP Woven Bags

Short answer? Absolutely. But let me take you behind the scenes of what that actually means, because it’s not just picking a paint color and slapping it on a bag. As someone who’s spent 16 years standing next to our production line, troubleshooting color runs, and talking to hundreds of clients from small farms to large retail chains, I can tell you that customizing PP woven bag colors is equal parts science, art, and common sense. It’s also one of the biggest ways our clients can make their packaging stand out, and honestly, it’s one of my favorite parts of the job.

Let’s start with the basics: what even is a PP woven bag? For anyone who’s not in the packaging world, PP stands for polypropylene, a durable, lightweight plastic that’s melt-extruded into thin strips, woven into a fabric, then laminated or coated to make it waterproof and tear-resistant. That polypropylene is naturally a pale, creamy white (called “natural PP”), so when we talk about custom colors, we’re not just adding dye to fabric—we’re integrating color straight into the polymer itself, for the most part.

Wait, hold on—there are two main ways to add color to PP woven bags, right? Let’s break that down because that’s where a lot of clients get confused, and where I’ve seen too many mistakes happen if you don’t know the difference.

The first method is mass coloring, which is adding color pigment to the polypropylene resin before it’s extruded into strips. That’s the method we use for 90% of our custom color orders at our shop. Here’s why it’s better for most clients: the pigment is bonded into every fiber of the bag, so the color doesn’t fade, scratch off, or rub away even after months of being hauled around in a truck, dumped in a warehouse, or left out in the sun. We’ve had a client who uses our custom blue PP bags for bulk seed packaging, and two years later, when we got a reorder, their old bags were just as bright as the new ones. That’s not a fluke—it’s how mass coloring works.

The second method is printing color on the surface of the bag, which is what you’d do for logos, text, or small design elements. That’s not “customizing the bag’s base color,” though. If you want a bag that’s bright pink, not just a white bag with a pink logo, you need mass coloring. I can’t tell you how many times a small business owner has come to us saying, “I need 10,000 custom purple bags” and thought they could just print purple on white. When we explain that printing will wear off after a few uses, they’re usually surprised—but once they see the difference, they’re glad we brought it up.

Now, the fun part: what colors can you actually get? A lot of people think PP woven bags are limited to primary colors, but that’s not true. Our lab team has matched everything from soft pastel mint green for organic vegetable packaging to deep, rich burgundy for wine shipping to neon safety yellow for construction material bags. The key here is that we use pigment masterbatches—pre-mixed, concentrated pigments that are designed specifically for polypropylene. These masterbatches are tested to be compatible with our extrusion process, so they don’t cause the strips to break, clog the machines, or result in spotty, uneven color.

But there are a few factors that affect what colors we can pull off, and I’ve learned over the years that being upfront about these factors is way better than promising a color and disappointing a client. First, the base resin you choose matters. Natural PP is the lightest base, so it makes colors look bright and true. If someone wants a darker color, sometimes we can use a semi-opaque base PP to cut down on how much pigment we need, but for very light colors—like a pale baby blue—natural PP is non-negotiable. We once had a client who wanted a custom lavender bag, and at first they insisted they could use a recycled PP base (which is a popular, eco-friendly option for many of our clients). But recycled PP has yellow undertones, so the lavender would have come out more like a grayish mauve. We showed them a test swatch, and they switched to natural PP, and the final product was exactly what they pictured.

Second, thickness of the bag affects color vibrancy. A thin, lightweight PP woven bag (say, 70 grams per square meter, which is common for grocery or small retail bags) will show color a little differently than a heavy, 150 GSM bag used for bulk gravel or animal feed. The thicker the bag, the more pigment it can hold without looking dull. For light, thin bags, we have to adjust the pigment concentration slightly to make sure the color doesn’t wash out, and for very thin bags, we might recommend a white laminate coating under the color to make it pop even more.

Third, weather resistance matters for outdoor use. If you’re using PP woven bags for things that will be stored outside—like firewood, construction materials, or garden supplies—you need pigments that are UV-stabilized. Regular pigments will fade to a pale ghost of their original color after a few months in direct sunlight. We keep a stock of UV-stabilized masterbatches specifically for this reason, and I always advise clients who plan to use their bags outdoors to request that upgrade. It adds a small cost, but it’s nothing compared to reordering bags because the color faded and your product looks unprofessional.

Now, let’s talk about the process, because knowing what to expect when you order custom color PP woven bags takes the mystery out of it. When a client reaches out to us asking for custom colors, here’s what happens next. First, we have a 15-minute chat (sometimes longer, if they’re detail-oriented like most of our repeat clients) to get the basics: how many bags they need, what size, what weight, what the bags will be used for, and if they need any add-ons like liners, reinforced handles, or UV resistance. Then, we send them a color matching form—they can either send us a physical sample of the color they want (a fabric swatch, a piece of packaging, even a paint chip) or give us a Pantone color code, which is the universal standard for color matching.

Once we have that, our lab team mixes a small batch of pigment masterbatch, extrudes a test strip, and sends us a physical swatch of the color. We send that swatch to the client for approval. This is the step that saves us from so many headaches—no more, “That’s not the blue I wanted!” Because they get to see and touch the actual color before we run a full production order. For small orders (under 5,000 bags), the test swatch is free, and we usually get approval within 24 hours. For larger orders, we might do two test swatches to make sure we get it exactly right.

Then, production starts. A full production run for custom colored bags takes about 7 to 10 days, depending on the order size and complexity. We run a “start-up run” of the first few hundred bags to make sure the color is consistent across the whole run—this is called a color validation check, and it’s non-negotiable for us. We’ve had clients come to us after bad experiences with other suppliers who skipped this step, ending up with bags that were bright at the start and faded halfway through the order. We don’t let that happen here.

Now, let’s get practical about costs, because I know that’s on everyone’s mind. Custom color PP woven bags aren’t that much more expensive than standard ones, but there are a few factors that affect the price. The color itself: lighter, pastel colors usually cost a little less than deep, dark colors, because you need less pigment to get a consistent shade. Custom, non-standard colors (like that lavender I mentioned earlier) might cost a tiny bit more because we have to order a small batch of the exact pigment masterbatch. Volume is a big one too—ordering 10,000 custom bags is way cheaper per unit than ordering 1,000. And if you need add-ons like UV stabilization, liners, or reinforced seams, that adds a small percentage to the total cost, but it’s worth it for the durability.

I want to mention something that’s super important to me as someone who runs a sustainable business: custom colored PP woven bags can be eco-friendly too. A lot of people think “custom” means more waste, but that’s not true. We can source PP resin that’s made from recycled plastic for custom colors, as long as the color is dark enough to hide any minor discoloration from recycled material. We also print our logos and text with water-based inks, which are non-toxic and don’t leave harmful chemicals on the bags. For clients who are shipping products for food or organic agriculture, we have food-grade color pigments that are FDA-approved. That’s a big one—organic farmers won’t use bags with any harmful chemicals touching their produce, so we make sure our custom colors meet those standards.

I’ve seen firsthand how custom colored PP woven bags can make a business stand out. Last year, a small family-owned coffee roaster reached out to us. They were tired of their generic white PP bags getting lost on store shelves next to big brands. They wanted custom bags in a deep forest green, with their logo printed in gold. We matched the forest green, used food-grade pigment, and added a thin liner to keep coffee fresh. When they showed up to a local farmers market, people were stopping them just to ask where they got their bags—sales went up 18% that quarter, and they’ve been a repeat client ever since. That’s the power of custom color: it’s not just a bag, it’s a way to tell your brand’s story.

Another example: a construction supply company that uses custom neon yellow bags for their fasteners. The bright yellow makes it easy to spot the bags in a messy job site, and the UV-stabilized pigment means they don’t fade when left outside. They used to use plain white bags, but their workers were always losing them in piles of lumber and concrete. Now, they can see a neon yellow bag from 50 feet away, and they’ve cut down on lost inventory by 25%. That’s the practical side of custom colors that a lot of people don’t think about.

Now, I know there are still questions you might have. What if I need a small order, like 500 bags? Can I get custom colors? Yes, we work with everyone from small startups to large corporations. What if I don’t have a Pantone color code? Just send us a photo of the color on your phone (we’ll adjust for lighting to get the closest match) or a physical sample, and we’ll handle the rest. Can I change the color later? As long as we haven’t already ordered the pigment masterbatch for your color, yes, we can adjust. Once the pigment is mixed, though, we can’t reuse it, so it’s best to make color changes early in the process.

If you’re on the fence about whether to customize the colors of your PP woven bags, let me leave you with this: packaging is often the first thing a customer sees. If your bags are plain, generic, and the same as every other brand, you’re blending in. If your bags are a color that’s unique to your brand, durable enough to get the job done, and built to last, you’re standing out. At our shop, we don’t just sell PP woven bags—we help our clients turn their packaging into a marketing tool, a practical solution, and a reflection of their brand.
