Twisted-Edge Automatic Bag Packing Machine (PLC Controlled)
Built for reliable sachet production in demanding daily operation, the Twisted-Edge Automatic Bag Packing Machine combines bag forming, dosing/filling, and sealing into a compact stainless-steel system. Designed around PLC automation and stable mechanical transmission, it supports liquid, powder, and granular products using composite packaging films. With a film width up to 180 mm and a flexible bag-size range for small to medium pouches, the machine delivers consistent sealing quality, clean cutting, and repeatable output—making it an efficient choice for manufacturers who need dependable packaging performance without excessive footprint or complexity.
Product Features
All-in-one forming, filling, and sealing: Integrates bag making, product filling, and final sealing in one continuous workflow to reduce manual steps, streamline production, and improve batch-to-batch consistency.
Leak-resistant horizontal sealing for liquid sachets: A dedicated 1 mm horizontal sealing leak-proof line (for liquid applications) strengthens seal integrity, helping minimize leakage risk during conveying, storage, and transport.
Twisted-edge adhesive sealing structure: The twisted-edge adhesive sealing method provides a firm closure and a neat seal appearance, supporting stable performance across different product states (liquid, powder, particle) and helping maintain package integrity over time.
PLC-controlled automation for repeatable cycles: PLC control enhances operational stability and repeatability, supporting consistent bag length control, coordinated sealing actions, and reliable production rhythm while reducing dependence on manual intervention.
Practical speed with controlled dosing accuracy: Designed for 20–40 bags/min, with measurement accuracy of ±1–10% depending on product characteristics and fill volume—balancing throughput and real-world packaging control for routine production.
Hygienic stainless-steel build: The stainless-steel body improves corrosion resistance and simplifies cleaning, making the machine suitable for environments that value hygiene, durability, and long-term equipment stability.
Professional sealing finish options: Horizontal sealing width is 8–10 mm, with selectable patterns such as diagonal mesh (1 mm spacing) or straight pattern (2 mm spacing) to meet different appearance and performance preferences.
Clean separation with flexible cutting modes: Supports flat cut or serrated cut via an independent cutter, with 3 mm spacing between cutters to achieve tidy bag separation and stable cutting performance during continuous running.
Adaptable format range for small sachets: Supports a wide bag-making range (bag width 20–80 mm; bag length up to 150 mm), enabling quick adaptation to different SKUs, serving sizes, and packaging presentations within the standard format capability.

Application Areas
Liquid sachet packaging: Ideal for single-serve or small-dose liquid products where seal reliability is critical. The dedicated leak-proof line supports stronger sealing performance for liquids used in food, daily chemical, and similar applications.
Powder sachet packaging: Suitable for powder products that require stable bag forming and consistent sealing, supporting both consumer goods and industrial powders where clean sealing and steady output are essential.
Granule/particle sachet packaging: Supports efficient packing of granules and small particles, delivering repeatable sealing quality and neat cutting for products that benefit from fast, consistent small-bag production.
