The Back Sealing Strip Packaging Machine is a fully automatic vertical form-fill-seal (VFFS) solution engineered for high-precision strip and small pouch packaging. It integrates film forming, dosing, filling, sealing, and cutting into one streamlined system, helping manufacturers achieve consistent pack appearance and stable output while reducing manual labor. Built around a stainless-steel frame and a variable-frequency motor crank bag-pulling structure, the machine delivers smooth film transport and reliable repeatability for small to medium-size package formats. With PLC control and photoelectric tracking, it maintains accurate film positioning and clean seals on composite packaging films, making it well-suited for liquids, powders, and granular products that require dependable barrier protection and shelf-ready presentation.
Product Introduction
Designed for continuous production environments, this back-sealing strip packaging machine focuses on efficiency, sealing integrity, and flexible formatting. The back seal keeps the front panel clean and branding-friendly, while the horizontal sealing system provides optional diagonal mesh or straight patterns to match different tactile and visual requirements. The machine supports composite films commonly used across food, pharmaceutical, daily chemical, and industrial sectors, and its heat-sealed bag pulling mechanism helps minimize film deviation for consistent bag length and neat cutting. For plants seeking stable automation with straightforward parameter management, the PLC architecture simplifies setup, monitoring, and routine operation.
Product Features
Built to balance speed, accuracy, and durability, the machine offers stable output, adaptable sealing/cutting options, and a hygienic structure suitable for demanding factory conditions.
- Stable high-throughput operation: supports 20–40 bags/min to maintain continuous production flow.
- PLC control with reliable tracking: PLC-based control logic improves stability and makes parameter adjustment intuitive; photoelectric tracking helps keep print registration and bag positioning consistent.
- Composite film compatibility: optimized for widely used laminated/composite packaging materials to support barrier performance and shelf-life protection.
- Clean, consistent sealing: twisted edge adhesive sealing enhances seal integrity and helps improve package appearance.
- Selectable horizontal seal patterns: choose diagonal mesh or straight pattern to meet different product and branding requirements.
- Accurate film feeding and bag length control: variable-frequency motor crank structure with heat-sealed bag pulling improves feeding accuracy and reduces film wandering.
- Configurable cutting formats: flat cut or serrated cut with an independent cutter design for neat separation and consistent edge quality.
- Hygienic stainless-steel construction: corrosion-resistant body supports easy cleaning and long service life.
- Integration-ready customization: overall machine dimensions can be tailored to plant layout and upstream/downstream equipment docking needs.
