Product Advantages
Integrated Forming–Filling–Packaging Workflow
This machine consolidates bag making, filling, and final packaging into one continuous automated process, significantly reducing manual intervention, boosting throughput, and standardizing pouch quality. It is particularly suited for operations requiring repeatable bag dimensions and consistent sealing integrity, ensuring a streamlined production flow.
Stable Sealing Performance for Multiple Product Types
Featuring controlled back sealing with adjustable width, the machine provides stable pouch construction for a wide array of products. For liquid applications, an optional dedicated horizontal sealing leak-proof line enhances sealing integrity, minimizing seepage risks and ensuring cleaner, more reliable seals for fluid materials.
Dual Cutting Styles for Different Presentation Needs
Manufacturers can choose between flat cut and serrated cut, thanks to an independent cutter design with a 3 mm spacing between cutters. This flexibility allows tailoring pouch appearance and opening convenience to specific market demands and product positioning strategies.
Accurate Film Tracking and Efficient Control
Equipped with a JULONG dual-color photoelectric eye, the machine ensures precise film registration and alignment. Coupled with PLC control, it enables straightforward parameter setting, stable operational logic, and user-friendly daily operation, collectively reducing film waste and enhancing packaging consistency.
Durable Stainless-Steel Construction
Constructed from stainless steel, the machine offers superior corrosion resistance and ease of cleaning, making it a practical and hygienic choice for environments that demand long-term mechanical stability and compliance with sanitary standards.
