The Back Sealing Strip Packaging Machine is a fully automatic solution designed for precise forming, filling, and sealing of small to medium-size strip and pouch packages. Built with a stainless-steel structure and driven by a variable-frequency motor crank bag-pulling system, it delivers stable performance for high-throughput packaging lines. With PLC control and reliable photoelectric tracking capability, the machine supports composite packaging films and produces clean, consistent seals for a wide range of products including liquids, powders, and granular materials.
Product Advantages
This machine combines efficient output with dependable sealing quality, making it ideal for manufacturers seeking consistent pack appearance and reduced labor input. The PLC-based control architecture improves operational stability and simplifies parameter setting, while the heat-sealed bag pulling mechanism enhances feeding accuracy and minimizes film deviation. Multiple sealing and cutting options help adapt the packaging style to different brand needs and material characteristics.
- High efficiency and stable output: supports 20–40 bags/min for continuous production.
- Wide material compatibility: designed for composite packaging films commonly used in food, daily chemicals, and industrial products.
- Consistent sealing performance: twisted edge adhesive sealing enhances integrity and improves shelf presentation.
- Flexible seal pattern selection: horizontal seal available with diagonal mesh or straight pattern for different tactile and visual requirements.
- Precision dosing support: measurement accuracy of ±1–10% (depending on product properties, film, and fill quantity).
- Configurable cutting style: flat cut or serrated cut with independent cutter design and defined spacing for neat separation.
- Durable, hygienic build: stainless-steel construction supports easy cleaning and long service life in demanding environments.
- Customization-ready: overall machine size can be customized to match plant layout and integration requirements.
