Fully Automatic Strip Back Sealing Packaging Machine
The Fully Automatic Strip Back Sealing Packaging Machine is designed for continuous, high-efficiency strip back sealing applications where consistent bag forming, strong seals, and dependable cutting are essential. Featuring a twisted-edge vertical sealing structure paired with diagonal straight horizontal sealing, the machine produces neat, secure seams that help improve package integrity during handling, storage, and transportation. Its PLC-based automation architecture and touch-screen HMI allow operators to complete setup, recipe storage, and parameter adjustments quickly, supporting stable output while reducing reliance on manual experience.
Built with food-grade 304 stainless steel and engineered for clean, production-ready performance, the machine integrates precision temperature control across a wide 0–300℃ range to accommodate different film structures and sealing requirements. It processes flexible packaging films in the 0.04–0.08 mm thickness range and supports a broad bag size window, enabling fast changeovers between product specifications without sacrificing sealing quality. With a compact layout and automation-focused configuration, it fits well into modern packaging lines that demand throughput, repeatability, and hygienic operation.
Product Features
Stable automation with PLC control: The PLC control system ensures reliable cycle timing and repeatable process execution. The touch-screen HMI provides an intuitive interface for real-time adjustments, recipe management, and fast switching between product settings, helping minimize downtime and reduce human error.
Wide temperature adaptability: Adjustable sealing temperature from 0–300℃ supports a variety of heat-sealable material structures within the specified thickness range. This flexibility helps maintain seal strength and appearance across different film types and packaging requirements.
Premium hygiene and durability: The 304 stainless steel body enhances corrosion resistance and simplifies cleaning, making the machine suitable for environments with strict sanitation expectations and frequent washdown-friendly maintenance routines.
High-quality sealing structure: Twisted-edge vertical sealing combined with diagonal straight horizontal sealing is optimized for tidy seam appearance and secure closure performance. This design supports consistent packaging presentation while reducing seal defects caused by film drift or unstable forming.
Flexible cutting options: Flat cut and serrated cut are selectable to match different consumer-opening preferences and product presentation needs. Flat cut supports clean, sharp edges, while serrated cut enhances easy-tear functionality for convenience-oriented packaging.
Servo-driven bag pulling: Siemens servo motor heat-sealing bag pulling delivers accurate film feeding and stable bag length control. This helps maintain dimensional consistency, improves sealing alignment, and supports smooth running in continuous production scenarios.
Broad format compatibility: The machine accommodates bag lengths from 50–200 mm and widths from 25–150 mm, supporting a wide range of SKU formats. Combined with film thickness compatibility, it provides strong versatility for manufacturers with varied packaging specifications and frequent changeover demands.

Application Fields
This machine is suitable for automated strip back sealing tasks across industries that require dependable sealing strength, consistent package appearance, and efficient throughput. In food packaging, its 304 stainless steel construction and stable temperature control support hygienic operation and repeatable sealing results. In medical and healthcare-related packaging, PLC-driven control and consistent process parameters help improve uniformity and reduce variability between batches. For industrial parts and components, the machine provides reliable closure performance that supports protection during shipping, storage, and inventory handling.
It is particularly well suited for manufacturers managing multiple SKU sizes or frequent specification changes. With adjustable settings, wide bag size compatibility, and film thickness support, the system enables efficient changeovers and stable production performance—whether for long-run output or batch-based packaging where flexibility and repeatability are equally important.
