Back Sealing Strip Packaging Machine
The Back Sealing Strip Packaging Machine represents a pinnacle of automated packaging technology, engineered to deliver precise, consistent, and high-volume packaging for liquids, powders, and granular products. This fully integrated system seamlessly combines bag forming, precise product dosing, and final sealing into one continuous, PLC-controlled operation. At its core, a robust variable-frequency motor crank pulling mechanism ensures stable film handling and bag advancement, while the heat-sealed bag pulling method provides superior traction and operational reliability. With a substantial 350 kg construction, the machine is built for endurance in demanding production environments. It offers manufacturers exceptional versatility through customizable sealing textures—including diagonal mesh or straight patterns—and a choice between flat or serrated cutting, allowing for tailored packaging aesthetics and functionality to meet diverse market and consumer needs.
Product Features
Automated, Integrated Packaging Process: This machine eliminates manual intervention by integrating bag forming, filling, and sealing into a single, streamlined automated workflow. This integration significantly boosts production throughput, minimizes labor costs, and guarantees uniform package quality and integrity across extended, high-speed production runs, ensuring every unit meets strict quality standards.
Precision Engineered with PLC Control: Central to the machine’s performance is its advanced Programmable Logic Controller (PLC) system. This provides unparalleled stability in managing all critical parameters for sealing, motion coordination, and timing. The system ensures highly repeatable operation, facilitates quick changeovers for different products, and allows for seamless integration into modern, smart production lines, enhancing overall operational efficiency.
Stable and Reliable Film Handling: The combination of a variable-frequency motor-driven crank structure and a heat-sealed bag pulling mechanism guarantees smooth, controlled, and consistent film advancement. This design is particularly effective when processing composite packaging films, preventing film slippage or misalignment and maintaining precise registration even at elevated operational speeds, which is crucial for product presentation and sealing quality.
Robust Sealing with Aesthetic Flexibility: The machine employs a reliable twisted edge adhesive sealing method for strong, durable seals. For horizontal sealing, it offers two distinct pattern options: a diagonal mesh pattern with 1 mm spacing for enhanced grip and a unique visual texture, or a clean, classic straight pattern with 2 mm spacing. The back sealing is executed without a pattern, resulting in a neat, professional, and smooth finish that elevates the overall package appearance.
Versatile Cutting Options for Functional Design: An independent cutter structure provides the flexibility to choose between a clean flat cut or a consumer-friendly serrated cut. This allows manufacturers to tailor the package edge style based on product type, brand positioning, and end-user convenience for easy opening, directly supporting downstream packing and retail requirements.
Broad Material and Product Compatibility: Designed for maximum versatility, the machine expertly handles liquid, powder, and granular products. It is compatible with high-barrier composite packaging films, making it ideal for a wide spectrum of applications—from food ingredients like flour, seasonings, and additives to daily chemical products such as detergents and industrial powders—ensuring excellent product protection and extended shelf life.
