Core Features

Multi-lane high speed, massive capacity: 2-16 lanes customizable, speeds up to 200-800 bags/min (depending on the number of lanes), each lane independently driven by a servo motor, with high synchronization accuracy and stable operation.
Four-side full sealing, no powder leakage, no air leakage: upper and lower films are matched and heat-sealed on four sides with patterned pressure, high sealing strength, suitable for warm pack iron powder / heating agents, preventing powder leakage and bloating, extending shelf life.
Precise metering, independently adjustable per lane: each lane has an independent discharge system (measuring cup / auger / electronic scale optional), metering range 0.5-50g, accuracy ±3%-±5%, parameters set independently per lane without mutual interference.
Intelligent control, easy operation, low maintenance: PLC + touchscreen with Chinese/English interface, one-touch setting of bag length, speed, and temperature; photoelectric automatic color-mark tracking; automatic fault diagnosis, automatic alarm and shutdown for film shortage / material breakage / mark abnormality; automatic counting, batch number printing, and easy-tear notch / dotted-line cutting integrated.
Strong packaging material adaptability: suitable for PET/AL/PE, PET/PE, NY/AL/PE, non-woven laminated films, etc.; automatic temperature control with independently adjustable vertical and horizontal sealing temperatures, adaptable to different materials.

Industry Advantages

5-10x efficiency improvement: multi-lane parallel operation greatly reduces per-pack labor and equipment costs.
Reliable sealing: four-side seal + pressurization prevents powder leakage and bloating, improving product pass rate.
Quick changeover: bag length, speed, and temperature adjusted with one touch on the touchscreen, no complex mold changes required.
Compliance and hygiene: 304 stainless steel, dust-free design, meeting warm pack / pharmaceutical-grade production standards.

Scope of Application

Warm packs, uterine warming patches, foot warming patches, neck patches, lumbar patches, fever cooling patches and other sheet-type heating / physiotherapy products; also suitable for four-side-sealed sheet products such as medicinal plasters, face masks, and disposable consumables.
