Vertical bag sealing machine

Vertical bag sealing machine stands upright for tall plastic bags. Adjustable sealing height and temperature, firm leakproof seal, widely used for grain, feed, chemical powder packaging bags.

Core Advantages

  • Three-in-One Continuous Operation: Combines product conveyor transport, thermal film sealing, and batch/date printing into a single seamless, automated workflow, dramatically boosting packaging throughput.

  • Heavy-Duty Vertical Stand Design: Engineered specifically for bulky packages, heavy woven bags, and liquid-filled pouches. The vertical configuration prevents dry powders or liquids from spilling during the sealing process, supporting a massive conveyor weight limit of up to 15 kg.

  • Precise Temperature & Speed Sync: Equipped with an electronic constant-temperature control system (0-300℃) and a stepless speed regulating motor (0–10), ensuring air-tight, professional 10mm seals across diverse film materials (PE, PP, laminated foils).

  • Adaptable Structural Formats: Built on a highly modular chassis, this series can be factory-configured in horizontal, vertical, or integrated stand-feet positions to align perfectly with your pre-existing packaging line heights.
