Automatic Paper Cup Machine for Bubble Tea & Milk Tea Cups (12oz–24oz)
High-Speed Industrial Deep-Cup Forming Technology: Precision Bottom Ultrasonic Sealing, Servo Feeding, and Heavy GSM Kraft & PLA Capability
Why Milk Tea Cups Need a Dedicated Machine Setup
Handling deep draws, concentrated fluid mass, and high-tensile multi-layer substrates requires purpose-built engineering.
Heavy Caliper Substrate (250–350 gsm)
Milk tea and iced beverage cups rely on dense base stock (250 to 350 gsm) combined with dual-side polymer coatings to resist moisture softening. Conventional forming tooling is engineered for lighter paper grades (170–220 gsm). Operating dense board on uncalibrated dies generates severe sidewall creasing, incomplete blank insertion, and immediate motor strain.
Deep Hydrostatic Pressure Resistance
With heights frequently exceeding 150mm to 180mm, tall 22oz and 24oz vessels exert heavy downward liquid pressures. Ordinary coffee cup makers fail to apply uniform radial compression during heating cycles, leading to microscopic seam gaps. Dedicated machines deliver controlled tonnage and dual-step knurling to guarantee a leak-proof bottom seal.
Rigid Top Rim Curling Precision
Bubble tea operations depend entirely on puncture seals and airtight plastic injection lids. If top curling creates elliptical discrepancies or loose interior diameters, lids pop open under transport. Our dedicated cams enforce high-pressure multi-stage rim flanging, yielding strict geometric concentricity and exceptional cup rim rigidity.

🤖 Features That Cut Your Waste Rate
Engineered to eliminate scrap, minimize tool maintenance downtime, and maximize usable line yields.
Closed-Loop Servo Paper Feeding
Traditional mechanical ratchet linkages generate positional drift over prolonged operational cycles. Our equipment utilizes integrated high-torque servo motors paired with optical micro-sensors to feed bottom reels with precise step-distance tolerances (±0.1mm), reducing web trim off-cuts and saving up to 8% in paper scrap annually.
Quick-Change Tooling Architecture
Switching cup tooling from standard 16oz to supersized 22oz or 24oz units is engineered for efficiency. Modular dies, pre-aligned dowel locators, and quick-release knurling modules bring full tooling switchovers down to under 4 hours, compared to 10+ hours on dated legacy machinery.
Automated Inline Counting & Stacking
Finished cups are channeled via pneumatic tubing straight into integrated stacking tables with digital batching sensors. Eliminating physical hand-to-cup contact avoids cosmetic scuffing, maintains pristine sanitation compliance, and reduces secondary labor handling defects to virtually zero.
🌱 Eco-Friendly Coating Compatibility
Adapting precision thermal profiles for both conventional barrier films and compostable substrates.
Single & Double PE Polymers
Widely adopted for chilled beverage formulations. Dual PE liners preserve exterior walls from condensation-induced softening during humid summer seasons. Our copper heater array ensures deep polymer fusion without substrate yellowing or carbon residue deposits.
PLA Biodegradable Liners
Polylactic Acid coatings offer an environmentally certified profile but exhibit narrow thermo-bonding windows. The machine integrates dynamic ultrasonic side-sealing horns that introduce pinpoint acoustic friction, ensuring immediate molecular bonding without scorching delicate biopolymer membranes.
Unbleached Kraft & Aqueous Barriers
Earth-tone kraft paper and water-dispersible barrier formulations require stable surface tensions and controlled forming speeds. We verify material stretch limits, coating thicknesses, and humidity levels before tool sign-off to ensure defect-free curling and non-flaking performance.
