Product Features
Zero-Misalignment Sealing – Even on Jumbo Bags
Traditional sealers rely on mechanical gears and chains that wear out, causing crooked seals on large bags. Our gear motor + stepper motor dual-drive system synchronizes upper and lower belts electronically-not mechanically. The result: dead-straight, consistent seals every time, with dramatically fewer rejects and less downtime.
Built for Heavy-Duty Industrial Environments
Seals bags weighing up to 50kg-ideal for:
25–50kg flour, sugar, grain, and feed bags
Chemical powders, fertilizers, and resin pellets
The vertical orientation prevents spills from liquids or fine powders, keeping your work area clean and safe.
Versatile Material Compatibility
Dual PID controllers deliver stable heat from 0–300℃, so you can switch between:
PE, PP, laminated films
Mylar, cellophane, and other heat-sealable thermoplastics
Adjustable pressure rollers and PTFE non-stick belts ensure a strong, wrinkle-free seal on every material.

One Machine, Two Jobs – Seal & Code Simultaneously
Eliminate separate printing steps. Built-in coding options let you print batch numbers, expiry dates, or lot codes directly on the seal line during sealing:
Hot‑stamp coding – crisp 2-line text (up to 20 characters)
Inkjet printing – high-speed variable data
No extra equipment, no extra labor.

FAQ
Q: What is the maximum bag size and weight this machine can handle?
A: Up to 100×100cm bags, with conveyor supporting 30–50kg loads depending on model.
Q: Can it seal liquid-filled or powder-filled bags?
A: Yes-the vertical orientation is specifically designed for liquids, powders, and granular products that would spill in horizontal sealers.
Q: How does the dual-motor system improve sealing quality?
A: It synchronizes upper and lower belts electronically, eliminating the misalignment common with mechanical chain/gear drives-critical for large bags where even slight drift causes crooked seals.
Q: What types of coding/printing are available?
A: Options include hot‑stamp coding (2 lines, up to 20 characters/line) for batch/date, and inkjet printing for high-speed variable data.
Q: What materials can this machine seal?
A: PE, PP, laminated films, cellophane, Mylar, and most heat‑sealable thermoplastics.
Q: What maintenance is required?
A: Regular cleaning of PTFE sealing belts; periodic checking of belt tension and replacement of heating tubes (typical lifespan 2000+ hours).
Q: Can the sealing height be adjusted for different bag sizes?
A: Yes-the conveyor stand is height‑adjustable from 100 to 1000mm, and the pressure rollers adjust automatically for varied bag thickness.
Q: What is the typical ROI period?
A: Most customers achieve ROI within 6–12 months through reduced rejects, eliminated secondary coding steps, and increased packaging line speed.
