How to Sublimate Can Coolers and Koozies

Few products sell in bulk as easily as custom can coolers. Couples order them by the hundred for weddings, families want them for reunions and vacations, and businesses hand them out at events. Sublimated can coolers are inexpensive to produce, press in minutes and give you full-color, photo-quality designs that will not crack or peel. Here is how to sublimate the most popular koozie styles.

Choose Your Can Cooler Style

Our sublimation can cooler and koozie collection includes several styles, each sold in 10-packs:

What You Need

Press Settings

Neoprene can coolers are thicker than shirts and need less pressure than hard goods. Always start with the settings provided for your specific blank. If none are listed, many decorators start around the general polyester fabric range in our sublimation press settings cheat sheet (380–400°F with light to medium pressure) and adjust time with a test piece. Too much time or pressure can flatten the neoprene or leave a shiny outline.

Step-by-Step: Sublimating a Foldable Can Cooler

  1. Design for the image area. For our foldable coozie, that is 4" x 7.5". Add a small bleed if you want the design to reach the edges.
  2. Print mirrored on sublimation paper.
  3. Flatten and lint roll the can cooler. Lint and fibers cause white specks.
  4. Decide on one or two sides. For a full wrap, you can press one side, flip and press the other, or press a single long design across both sides of the flattened cooler.
  5. Tape the transfer ink side down so it cannot shift.
  6. Place butcher paper inside the cooler if pressing one side at a time, to stop ink from passing to the back.
  7. Cover with butcher paper and press with light to medium pressure.
  8. Peel hot in one smooth motion and let the cooler cool flat.

Wrap-Around and Flat Insulators

Flat Velcro insulators are the easiest to sublimate because there are no seams or folds. Design to the 3.5" x 8.75" imprint area, tape the transfer and press like a flat textile. They are perfect for bulk orders, since you can fit several on a large press at once if the pressure is even across the platen.

Avoiding Seam Lines and Fold Marks

  • Use a koozie platen or a firm insert to keep the cooler flat and open.
  • Keep seams at the edges, not in the middle of your design.
  • Use busy backgrounds or patterns that disguise small gaps where the folds are.
  • Do not over-press. Long press times can leave permanent fold lines in neoprene.

Design Tips for Event Orders

  • Weddings: names, date and a monogram or photo. Offer two designs in one order for both sides of the family.
  • Bachelorette parties: skinny can coolers with each guest's name.
  • Family reunions: family name, year and location, matched to the reunion shirt design.
  • Businesses: logo, website and phone number for trade shows and customer gifts.
  • Sports teams: bottle insulators with player names and numbers.

Bulk orders are where can coolers shine. Our guide to sublimation gang sheets explains how to print many designs at once to save paper and ink.

Troubleshooting

  • Faded colors: increase time slightly or check printer settings. Read why sublimation colors look dull.
  • Ink on the back side: place butcher paper inside the cooler.
  • Blurry edges: the transfer moved. Tape all corners.
  • Shiny press box: too much pressure or heat. Reduce pressure and use a protective sheet.

Frequently Asked Questions

Can I use HTV or DTF on can coolers instead?

Yes, both work on fabric-covered coolers, but sublimation gives the softest, most durable full-color result on white polyester blanks.

Do I need a special platen?

No, you can press flattened coolers on a standard platen. A koozie platen just makes loading easier and helps prevent fold marks.

How do customers wash them?

Hand wash with mild soap and air dry. Sublimated designs will not peel or crack.

Can coolers are a low-cost, high-volume product that customers order again and again for events. Pick the style that fits the occasion, keep your blanks flat and lint free, and test your settings before running a big order. Browse more ideas in our sublimation blanks collection.
