How to Choose a Cup Sealing Machine: Semi-Automatic vs Automatic, Rim Size, Film and Voltage

Quick Answer

Bubble tea cup sealers come in semi-automatic (manual cup loading and pressing) and automatic (load the cup and it seals and ejects automatically, 10+ cups per minute) models. Check the rim size (commonly 90 or 95 mm), that the sealing film (PP, PET or paper-cup film) matches your cups, and the voltage and plug: North America commonly uses 120 V while Taiwan uses 110 V, so confirm specs and certification needs before export.

Semi-Automatic vs Automatic

	Semi-automatic	Automatic
Operation	Manual loading and pressing	Seals and ejects automatically
Speed	Depends on staff	10+ cups per minute
Price	Lower	Higher

4 Things to Check

Rim size: 90 / 95 mm; a different rim needs a different mold.
Sealing film: PP film for PP cups, PET film for PET cups, special film for paper cups. See boba cups in bulk.
Voltage and plug: 120 V in North America; some locations require electrical safety certification (such as UL or CSA), so check locally.
Parts and service: heating plates and blades should be replaceable.
