Product Description

QLF700A pneumatic vertical sealing machine adopts vertical sealing structure with roller‑type conveying table, specially designed for large‑size or overweight bag packaging. It delivers powerful sealing capacity, easily seals single‑layer plastic film or composite bags with film thickness ≤0.2 mm.

Double‑heating version is available for special sealing demands, which can handle single‑layer film thickness over 0.2 mm.

Widely applied in chemical, grain, food and feed industries.

Key Features

  1. Neat & Firm Sealing Effect

    Pneumatic forced cooling after sealing shortens cooling cycle, improves sealing strength and obtains nice sealing appearance.

  2. Labor‑Saving Pneumatic Operation

    Vertical sealing structure plus roller conveyor greatly reduces operator workload. Mechanical lifting mechanism is equipped for products of different heights. Height scale enables fast adjustment to proper sealing position.

  3. Height‑Adjustable Roller Conveyor Table

    Adjust the conveyor height freely according to bag height to reach ideal sealing position.

  4. Simple Operation

    Trigger work by momentary button or foot pedal switch, time‑saving and labor‑saving.

  5. Single / Double Heating Optional Versions

    Single‑heating for ordinary bags; double‑heating for M‑shape bags.

  6. User‑Friendly Control Panel

    Concise control panel with counting function and emergency stop switch for safe and convenient operation.
