Premium Sublimation Coffee Koozie Blanks & Wholesale Sleeves

• Yes. Our blanks are pre-audited for flatness and heat resistance—just print and press.

• Logo clarity is a synergy of the material base and the printing process. While we provide a specialized 200g+ double-white polyester base to prevent rubber-core bleed-through, a perfect result also depends on professional execution.
• Our Factory Standard: We use 300+ DPI high-definition transfer paper and calibrated industrial heat presses to ensure the exact balance of temperature, pressure, and time.
• Troubleshooting: If you are sourcing material for your own printing, please ensure your transfer paper resolution is sufficient and your machine parameters are audited to prevent “ghosting” or fading.
• The “Pro” Solution: For logos requiring extreme detail or placement over complex patterns, we recommend Offset Heat Transfer (DTF) on top of the sublimated base. This provides a crisp, raised-texture logo that “pops” against any background.

• For maximum color vibrancy and production efficiency, we recommend 210°C – 220°C (410°F – 428°F)

   for 15 – 17 seconds with medium pressure. Our industrial-grade SBR core is specifically engineered to withstand this high-temperature rapid process without scorching or losing its signature 4-way stretch

• Yes. Our blank magnetic koozies feature a heat-shielded sandwich construction. The N52 magnets are protected by neoprene layers on both sides, ensuring they stay secure, functional, and won’t damage your heat press plates.

• Unlike foam, our sublimation neoprene koozies use a high-density SBR core that doesn’t “pancake” or shrink under heat. The 200g+ double-white polyester facing is also far superior for ink absorption, ensuring 100% color vibrancy and a professional retail finish.

Yes. Our blank neoprene coffee sleeves are engineered with a 12cm height and superior 4-way stretch elasticity. The tapered design ensures a snug, non-slip fit for 16oz (Grande), 20oz (Venti), and 24oz (XL) cups from major chains like Starbucks and Dunkin. The 6.3cm base diameter is specifically chosen to lock onto the lower half of most standard paper and plastic cups. For bulk sublimation blanks for coffee cups projects requiring specific heights or unbranded options, we also provide custom-cut unsewn neoprene koozies.
