Back Sealing Strip Packaging Machine
Built for efficient bag forming, filling, and sealing in one streamlined process, this Back Sealing Strip Packaging Machine is a stainless-steel, PLC-controlled solution for packaging liquids, powders, and granules with consistent performance. Designed for stable daily production, it supports flexible bag sizes within a compact range, delivers dependable sealing quality, and offers clean, precise cutting options. A dual-color photoelectric tracking system helps maintain accurate film positioning and reliable operation across different packaging materials.
Product Advantages
Integrated forming–filling–packaging workflow
The machine combines bag making, filling, and final packaging into a single automated cycle to reduce manual handling, improve throughput, and standardize finished pouch quality. It is well-suited for continuous operation where repeatable bag dimensions and consistent sealing strength are required.
Stable sealing performance for multiple product types
Back sealing with a controlled sealing width supports stable pouch construction for a wide range of products. For liquid applications, a dedicated horizontal sealing leak-proof line option helps enhance sealing integrity, supporting cleaner seals and reduced risk of seepage when processing fluid materials.
Dual cutting styles for different presentation needs
Choose between flat cut and serrated cut using an independent cutter design with a 3 mm spacing between cutters. This allows manufacturers to match pouch appearance and opening convenience to different markets and product positioning.
Accurate film tracking and efficient control
A JULONG dual-color photoelectric eye supports precise registration and alignment, while PLC control enables straightforward parameter setting, stable running logic, and easy operation for day-to-day production. Together, they help reduce film waste and improve packaging consistency.
Durable stainless-steel construction
The stainless-steel build supports improved corrosion resistance and easier cleaning, making the machine a practical choice for environments that demand hygiene-friendly equipment and long-term mechanical stability.
