Quick Answer

To use your KARAT Boba Sealer, place a filled cup under the sealing head, align the film, and press down for a few seconds. Clean it after each shift to avoid sticky residue and ensure a tight seal every time.

Why proper sealing and cleaning matter

A good seal keeps your boba drink fresh and leak-proof, which is especially important if you offer takeout or delivery. The KARAT Boba Sealer is designed for cafe and food service environments, so it’s built to handle frequent use—but only if you maintain it.

Residual syrup or tea on the sealing head can cause weak seals or film that sticks to the machine. Regular cleaning prevents these issues and extends the life of your equipment.

How to Use and Clean Your KARAT Boba Sealer

  1. Prepare the cup and film: Fill your cup with the drink, leaving about 1 cm of headspace. Place the cup on the sealing platform and pull the film over the top, ensuring it covers the entire rim. Check that the film is centered before lowering the head.
  2. Seal the cup: Pull the handle down firmly and hold for 2-3 seconds. The heat will bond the film to the cup rim. Release the handle and lift the cup to check the seal. If the film doesn’t stick, increase the sealing time slightly or check the temperature setting.
  3. Clean the sealing head after use: Unplug the sealer and wait for it to cool. Wipe the sealing head and platform with a damp cloth to remove any syrup or residue. Avoid submerging the machine in water. Clean after each shift to prevent sticky buildup that can weaken seals.
  4. Troubleshoot common issues: If the film doesn’t seal, check that the cup rim is dry and the film is not wrinkled. If the film sticks to the head, the temperature may be too high—reduce it slightly. Keep a small brush handy to remove film scraps from the sealing head.
