How to dye kraft paper?

by christina•

Hey there! If you’ve ever wanted to spruce up plain kraft paper for DIY projects, custom packaging, or even decor (and you’re probably here ‘cause you just got a roll of our kraft paper and wanna experiment), this is your no-BS guide to dyeing it right. I’m gonna keep this real—no fancy jargon, just what works, plus a few pro tips I’ve picked up from customers over the years. Kraft Paper

First off, let’s get one thing straight: kraft paper isn’t like plain white printer paper. It’s made from wood pulp (mostly softwood, usually pine or spruce) and has that natural brown hue from lignin, a compound that gives wood its structure. That’s why straight-up fabric dye? It doesn’t always stick, and sometimes it leaves that splotchy, uneven mess we’ve all avoided. As a kraft paper supplier, I’ve seen so many folks mess this up ‘cause they skip the prep step—so let’s start with that.

What You’ll Actually Need

Let’s keep this simple, no specialty stuff here. You probably already have most of this lying around:

  • Roll or sheets of kraft paper (duh, obviously ours works best, but any uncoated kraft—no waxed!—will do)
  • Dye: For kraft, I recommend fiber-reactive dye (like Rit DyeMore, it’s made for cellulose materials) or even fabric acid dye. Skip acrylic paint—too thick, won’t penetrate. If you want a super cheap option, coffee, tea, or even food coloring works for light, muted tones, but don’t expect deep, vibrant shades.
  • Hot water (not boiling, like 140-160°F/60-70°C—boiling can make kraft paper super brittle, trust me)
  • A big pot or bucket (plastic is fine, metal works too, just make sure it’s clean)
  • Salt (for fiber-reactive dye, it helps the color stick)
  • Vinegar (if you’re using acid dye, this is key)
  • Gloves (your hands will stain, save ‘em)
  • A stirring stick (wood or plastic, metal’s okay too)
  • Paper towels or a drying rack (no hang-drying over a shower—too much humidity)

Prep Step That Makes All the Difference

This is the part most people rush, and it’s why their dye job looks garbage. Kraft paper has tiny bits of residual pulp and that lignin I mentioned earlier that acts like a barrier. You need to “open up” the paper fibers so the dye can seep in. Here’s how:
Tear your kraft paper into the size you wanna use (or leave it whole, just know bigger sheets are trickier to handle) and soak it in warm water for 30 minutes. I’m talking fully submerged—no floating edges. Then take it out and squeeze gently—don’t twist or wring, that’ll crease it. You want it damp, not dripping.

If you’re going for a super even color, you can also pre-wash the paper with a tiny bit of dish soap (unscented) to strip any leftover processing oils. Rinse it good afterward—no suds left, or they’ll make the dye spotty.

How to Dye It (Two Methods, Pick What Fits)

Now for the fun part. I’ve tested both hot dyeing (best for vibrant, long-lasting color) and cold dyeing (easier, less mess) — here’s the lowdown on both.

Hot Dye Method (Vibrant, Fade-Resistant)

This is my go-to, especially if you’re using kraft for packaging or something that’ll get handled a lot.

  1. Fill your pot/bucket with the warm water (140-160°F, not boiling). Follow the dye’s package directions for how much to use—usually 1 tsp of dye per 2 cups of water for a deep color, less for pastels.
  2. Add the salt (1 cup per gallon of water) and stir until it’s dissolved. Salt is non-negotiable here—it makes the fiber-reactive dye bond with the kraft paper’s cellulose fibers instead of just sitting on top.
  3. Add your damp kraft paper gently—don’t just drop it in, that’ll cause creases. Make sure it’s fully submerged. If it floats, weigh it down with a clean stone or a glass bowl.
  4. Stir it every 5 minutes for the first 15 minutes, then let it soak for another 20-30. The longer it sits, the darker the color—just check it every 10 minutes once you hit the shade you want. Don’t leave it too long, or it might get too dark, and kraft can get weak from sitting in dye too long.
  5. Once it’s the right color, take it out and rinse it with cold water until the water runs clear. This stops the dye from bleeding later.

Cold Dye Method (No Stove Needed)

Perfect if you’re doing small sheets or don’t wanna mess with warm water. It’s not as fade-resistant as hot dyeing, but it’s great for crafts.

  1. Mix your dye in a bucket with warm (not hot) water, plus the same salt ratio as the hot method. Stir until the dye is fully mixed.
  2. Submerge your damp kraft paper, weigh it down if needed. Let it soak for 1-2 hours (check every 30 minutes—color builds slower cold).
  3. Rinse it the same way as the hot method once you’re happy with the shade.

Pro Tips I Learned From Customers (No BS)

  • Avoid waxed or coated kraft paper: If it says “waterproof” or has a shiny finish, dye won’t stick. Stick to plain, uncoated—our regular kraft rolls are perfect for this.
  • Test a scrap first: Always, always dye a small, hidden piece of kraft first. Different dye brands work differently, and every batch of kraft has a tiny color variation. I once had a customer who dyed a whole roll without testing, and the shade was 2x darker than they wanted—total waste.
  • Dry flat: Don’t hang the dyed kraft paper to dry. It’ll warp and crease. Lay it flat on a drying rack, or between two layers of paper towels (put a light book on top if it’s big) for a smooth finish.
  • Lighter tones work better on kraft: If you want navy or black, it’s possible but you’ll need a lot of dye, and it might make the kraft brittle. Muted colors like terracotta, soft green, or dusty pink look way better—they complement the kraft’s natural texture instead of fighting it.
  • For packaging: Let it cure: If you’re dyeing kraft for boxes or bags, let it dry for 24 hours before using it. This makes the color set so it doesn’t rub off on products.

What to Skip (Because I’ve Seen It Go Wrong)

  • Don’t use boiling water: I know it sounds like it’ll help the dye penetrate faster, but boiling water breaks down the kraft paper’s fibers, making it super flimsy—good for a craft project that gets tossed, bad for anything you wanna keep.
  • No acrylic paint straight up: It’ll crack and peel off the kraft paper, especially if it’s folded or bent. If you wanna use paint, mix it with a fabric medium first to make it flexible.
  • Don’t skip rinsing: If you don’t rinse until the water runs clear, the dye will bleed onto everything it touches—your fingers, your furniture, whatever.

Lunch Box Wait, and one last thing: if you’re a small business looking to do bulk dyeing for custom packaging, just reach out. I work with a ton of shop owners who need consistent, large batches of kraft that’s dyed to spec, and we can hook you up with the right paper and even some quick testing samples. No awkward forms, no long wait times—just send over what you need, and we’ll make it happen.
