Back Sealing Strip Packaging Machine
The Back Sealing Strip Packaging Machine represents a state-of-the-art automated solution engineered for the high-volume production of sealed pouches. This integrated system seamlessly combines bag forming, precise product dosing, and final sealing into a single, continuous operation. Designed with industrial robustness and precision in mind, it utilizes a PLC-controlled framework paired with a variable-frequency motor crank pulling mechanism to ensure stable and consistent performance. Ideal for packaging liquids, powders, and granulated materials, this machine transforms composite packaging film into finished, professional-grade pouches with exceptional reliability. Its solid 350 kg construction and advanced heat-sealed bag pulling technology guarantee dependable operation in demanding production environments, while offering versatile sealing textures and cutting options to meet diverse aesthetic and functional packaging specifications.
Core Product Features
This packaging machine is distinguished by a suite of advanced features that deliver efficiency, precision, and flexibility. The fully automated workflow integrates bag forming, filling, and sealing, significantly minimizing manual intervention, boosting production throughput, and ensuring uniform package quality across extended runs. At its heart, a sophisticated PLC control system provides unwavering stability in managing all operational parameters, from sealing temperatures to motion sequences, enabling repeatable performance, quick changeovers, and seamless integration into modern automated production lines.
The film handling system is engineered for utmost reliability. A variable-frequency motor coupled with a crank structure ensures smooth and controlled bag advancement, while the innovative heat-sealed pulling method enhances traction and consistency, particularly when processing composite films at higher operational speeds. Sealing performance is both robust and customizable. The machine employs a twisted edge adhesive sealing technique and offers flexible horizontal sealing patterns. Operators can choose a diagonal mesh pattern with 1 mm spacing for superior grip and a distinctive visual texture, or a straight pattern with 2 mm spacing for a clean, classic appearance. The back sealing is executed without a pattern, yielding a neat and professional finish.
Further customization is available in the cutting phase. An independent cutter structure allows for a choice between a flat cut or a serrated cut, enabling manufacturers to tailor the pouch edge style to specific product needs, consumer convenience, and downstream packaging processes. Finally, the machine boasts wide product compatibility. It is adeptly designed to handle liquids, powders, and granular particles, making it a versatile asset for packaging a broad spectrum of items—from food ingredients and seasonings to daily chemical products—all while utilizing composite packaging materials that enhance barrier properties and extend product shelf life.

Primary Application Fields
The Back Sealing Strip Packaging Machine serves a wide array of industries requiring efficient and reliable pouch packaging. In the food and ingredient sector, it is perfectly suited for packaging powdered substances like flour, starch, and baking mixes, as well as granular products including seasonings, soup blends, sugar, and dry food additives, where consistent seal integrity and reliable film handling are paramount.
For liquid pouch production, the machine offers specific advantages. With the availability of an optional integrated leak-proof line on the horizontal seal, it provides an ideal solution for packaging liquid products such as sauces, dressings, oils, and liquid condiments into pouches, demanding enhanced seal security and production stability.
The machine also finds significant application in packaging daily chemical and general industrial products. It effectively handles powders (e.g., detergents, cleaning agents), granules, and certain liquids that utilize composite film packaging. This makes it a dependable automation solution for manufacturers who require not only consistent performance but also a clean package presentation with the flexibility to choose sealing and cutting styles that align with brand identity and market requirements.
