About Milk Tea Sealing Machine (Bubble Tea Cup Sealer) — Manual, Semi & Automatic

A milk tea sealing machine (bubble tea cup sealer) applies heat and pressure to fuse a plastic or PLA film across the rim of a plastic or paper cup, creating a leak-proof, tamper-evident closure. Operators place the filled cup, the machine pulls film, heats and cuts a sealed disc, sometimes punching a straw hole. Used in milk tea shops, juice bars, cafés and yogurt/dessert outlets, it comes in manual, semi-automatic and fully automatic versions with custom-printed branding film.

How to Choose

  • Operation type: manual for low volume, semi-automatic for busy cafés, fully automatic for high-volume chains.
  • Cup size & material: match rim diameter (commonly 90/95 mm) and confirm PP, PET or paper cup compatibility and interchangeable molds.
  • Film type: choose PP/PET-printed film for branding or clear film; consider compostable PLA for sustainability.
  • Speed & footprint: balance cups-per-hour with counter space, power supply and workflow near the drink-finishing zone.

FAQ

Q: How does a milk tea cup sealing machine work?
A: A heated disc presses sealing film onto the cup rim, fuses it with heat and pressure, then cuts the film to form a leak-proof lid.

Q: What cup sizes do sealers support?
A: Common rim diameters are around 90 mm and 95 mm; many machines offer adjustable or multi-size molds for different cups.

Q: Which sealing film should I use?
A: Match the film to your cup plastic (PP or PET); printed film aids branding, clear film shows the drink, and PLA is compostable.

Q: Manual, semi-automatic or automatic—which to pick?
A: Manual suits low daily volume; semi-automatic balances speed and cost; automatic handles peak-hour rush with minimal labour.
