Automatic Plastic Bag Packing & Sealing Machine (Max 450 mm Film) — 1.8 m³/min Air Consumption
Engineered for continuous, high-output bag forming and sealing, this automatic plastic bag packing & sealing machine delivers stable performance for daily factory production. Built on a heavy-duty 600 kg frame and powered by a 380V/50Hz three-phase platform, it integrates reliable photoelectric registration, precise film pulling, and an independent cutting structure to create well-shaped pouches with clean edges and controlled trim waste. The machine is designed for heat-sealable laminate films and supports consistent sealing quality across long production runs, making it a practical choice for food and general commodity packaging lines that demand dependable automation, repeatable results, and strong safety compliance.
Product Features
Accurate film tracking for consistent registration: Equipped with a JULONG dual-color photoelectric sensor (“Ronic Eye”), the system improves printed mark detection and helps reduce misalignment, off-center seals, and scrap caused by unstable tracking.
Professional sealing appearance with strong integrity: The horizontal seal is formed with an 8–10 mm width and a single-sided diagonal mesh pattern (1 mm pitch), enhancing seal strength and giving finished pouches a clean, premium look. The back seal is 4–6 mm and pattern-free for a neat, standard finish.
Twisted-edge adhesive sealing structure: The sealing form is optimized for stable bonding and repeatable sealing quality on compatible heat-sealable laminate films, supporting consistent output in high-speed operation.
Precise film pulling and synchronized sealing: Motor crank type heat-sealing bag pulling, combined with encoder-controlled sealing action, supports steady film feeding and repeatable bag length control, improving overall forming consistency.
Independent round-corner cutting with low material waste: The standalone cutting device produces smooth corners and clean pouch edges. Typical waste is kept to 2–3 mm, helping control film consumption while maintaining an attractive bag profile.
Easy-open options for better consumer experience: An independent easy-tear device supports either a point-shaped easy-tear notch or a double easy-tear notch, enabling convenient opening without compromising seal integrity.
Industrial-grade electrical configuration: Key electrical components are sourced from Schneider or OMRON for improved reliability, long service life, and easier spare-parts availability.
Safety-focused design for production environments: Standard safety configuration includes a three-color tower light, Panasonic safety door detection switches, an emergency stop switch, and clear safety labels at heating and mechanical motion areas—helping operators work with greater confidence and compliance.
Pneumatic system compatibility for factory utilities: Designed to operate at 7–8 kg air source pressure with 1.8 m³/min air consumption, suitable for common plant compressed-air systems.
Material and product adaptability: Compatible with heat-sealable laminate films and suitable for packaging particles, powders, and liquids depending on the selected filling configuration. An optional 1 mm horizontal sealing leak-proof line is available for improved liquid packaging performance.
