The Back Sealing Strip Packaging Machine is an automatic strip packing solution designed for stable, high-efficiency pouch forming, filling, and sealing. Built with stainless-steel construction and PLC control, it supports composite packaging films and delivers consistent back-sealed strip bags for liquids, powders, and granules. With flexible cutting options and a compact bag-making range, it is ideal for manufacturers seeking dependable packaging performance with straightforward operation and maintenance.
Product Advantages
Reliable sealing for clean, professional packs: The twisted-edge adhesive sealing structure is engineered to produce firm, neat seals suitable for continuous production. For liquid applications, a 1mm horizontal leak-proof line helps strengthen sealing integrity and reduce the risk of seepage.
Stable automation with PLC control: PLC-based control improves repeatability, simplifies parameter setting, and helps maintain consistent output quality across shifts. Automated bag making, filling, and packaging functions reduce manual intervention and support efficient line operation.
Flexible cutting for different presentation needs: Choose flat cut or serrated cut using an independent cutter configuration. The cutter spacing is 3mm, supporting tidy strip separation and better downstream handling.
Accurate film tracking and positioning: Equipped with a JULONG dual-color photoelectric eye for dependable mark detection and film tracking, improving registration accuracy and reducing material waste during continuous running.
Production-ready build quality: Stainless-steel material enhances corrosion resistance and hygiene performance, making the machine suitable for a broad range of packaging environments where cleanliness and durability matter.
Compact strip-bag format: Designed for small bag widths and lengths, the machine supports high-utility single-serve and portion packs commonly used in consumer goods and industrial sampling.
