PM180L4-SYB Four-Row Automatic Snus Small Bag Back-Sealing Packaging Machine
The PM180L4-SYB is a four-row, back-seal automatic packaging solution engineered for continuous, high-efficiency production of snus granule sachets. Designed around stable film forming, accurate micro-dose metering, and repeatable heat sealing, it enables manufacturers to achieve consistent pouch geometry and clean sealing lines at scalable output. The machine integrates a four-lane rotary metering system, multi-zone temperature control, and selectable sealing/cutting configurations, making it ideal for brands expanding capacity as well as established factories seeking predictable throughput, reliable operation, and uniform packaging standards across long production runs. With compatibility for common composite films such as BOPP/PE and a maintenance-friendly layout, the PM180L4-SYB supports fast setup, steady rhythm, and dependable pouch quality for modern snus and nicotine pouch production.
Product Features
Four-lane synchronized output: Four rows run simultaneously with a stable operating rhythm, delivering 30–45 bags/min per lane. This multi-lane architecture increases total capacity while maintaining uniform forming, sealing, and cutting consistency across all lanes.
Rotary metering built for fine granules: The SYB-4-R four-row adjustable rotary dosing device is optimized for 0.4–0.6 g/bag snus granules. A self-weight adjustable measuring cup design supports stable feeding and convenient fine-tuning to match material flow, density variation, and target speed.
Intuitive PLC control and on-machine diagnostics: Inovance PLC with a 7-inch color touch screen (Chinese/English) provides clear parameter management, fault prompts, and self-diagnosis. Interlocks and alarms cover film run-out, safety door status, and abnormal operating conditions, while tri-color status lights improve line visibility on the shop floor.
Consistent back-seal quality with selectable cross-seal styles: The back sealing configuration delivers a clean back area with sealed left/right edges. Two sets of horizontal heat sealers allow selection between plain sealing and net/embossed patterns to enhance appearance, sealing strength, and handling characteristics according to film type and product requirements.
Flexible cutting for downstream preference: Dual knife sets support both flat cutting and serrated cutting, allowing fast adaptation to consumer tear preference as well as downstream cartoning, counting, and bundling processes.
Hygienic, GMP-oriented construction: Product-contact parts are manufactured in SUS304 stainless steel. The frame and electrical enclosure can be configured in SUS304 stainless steel or aluminum alloy. Key assemblies support easier disassembly for cleaning, helping reduce cross-contamination risk and supporting hygienic production expectations.
Reliable pneumatic and electrical architecture: Airtac pneumatic components and Schneider/OMRON electrical parts enhance durability and long-term stability. Omron 6-channel temperature controllers provide multi-zone temperature control with deviation alarms to help maintain stable sealing performance and reduce temperature-related defects.
Efficient film handling and reduced downtime: Gravity active film feeding helps maintain steady film tension for smoother forming and consistent registration. A fast film splicing/bonding workbench supports quick roll changes, while a four-row electric hot-knife film separation module enables neat lane separation for stable pouch forming.
Setup waste reduction support: An automatic waste-bag rejection function for debugging and commissioning stages helps reduce rework during setup, improving overall line efficiency and shortening time-to-stable production.
Cleaner sealing zone for better integrity: A dust removal unit above the horizontal sealing area (including vacuum) helps minimize granule dust accumulation near the sealing line, supporting improved seal integrity and cleaner finished pouch surfaces.

Application Areas
The PM180L4-SYB is designed for small snus pouch production using nicotine pouch/snuff-style granular materials and other fine granules that require stable micro-dosing, compact sachet forming, and reliable back sealing. It is well suited for snus and nicotine pouch manufacturing lines, contract packing operations, and factories seeking multi-lane high-speed sachet output with repeatable quality. Thanks to composite film compatibility and selectable sealing/cutting configurations, it can also be adapted for similar micro-dose granular products where consistent pouch size, sealing integrity, and clean finished appearance are critical for storage, handling, and downstream packing.
