The Ry-150KLB-F is a compact vertical sachet packaging machine designed for granule, powder, and small-item packaging at 20 to 40 bags per minute. With a measuring range of 1 to 500 milliliters and bag dimensions from 30 x 20 mm up to 200 x 150 mm, the machine serves pharmaceutical, nutraceutical, food, and chemical manufacturers who require precise portion control in small to medium sachet formats. The PLC control system with English-language interface manages the complete production cycle through a touch screen, allowing operators to adjust parameters without interrupting production.
Measuring 1140 x 1080 x 1800 mm and consuming 2 KW of power, the Ry-150KLB-F fits into production facilities where floor space is limited but automation is essential. The back-sealing architecture produces clean, professional sachets suitable for retail display, clinical trial supply packaging, and industrial sample distribution.

Key Features
- Touch Screen Operation: The color touch screen provides direct access to all machine parameters. Bag length, fill volume, sealing temperature, and production speed are adjustable on-screen, enabling rapid product changeovers without mechanical reconfiguration. The English-language interface eliminates translation barriers for international operators.
- PLC Control System: The programmable logic controller orchestrates every machine function in a synchronized sequence. Centralized control reduces the number of standalone controllers and interconnections, lowering the probability of component failure and simplifying troubleshooting when faults occur.
- Independent Temperature Control (plus or minus 1 degree Celsius): Each sealing station maintains an independent temperature control loop. The plus or minus 1 degree Celsius accuracy prevents the seal quality fluctuations that occur when shared temperature controllers cannot compensate for local heat loss or ambient temperature changes. This is particularly important when packaging powders that can interfere with seal integrity if residual product enters the seal area.
- Frequency Converter with Safety Seal Knife: The integrated frequency converter regulates motor speed across the production range. When the machine stops, the sealing knife automatically opens to prevent the heated jaws from resting on the film, which would cause burn-through and material waste. This protective action saves film and reduces the frequency of jaw cleaning.
- Enclosed Material Handling: The loading, unloading, and packaging zones are sealed during operation to contain dust within the machine. For granule and powder products, this enclosed design prevents airborne particles from contaminating the production environment, protecting both product quality and operator health.
- Single-Pass Full Automation: Measurement, bag forming, filling, sealing, date printing (optional), and product discharge are completed in one continuous operation. No manual handling is required between stages, reducing labor costs and eliminating the contamination risk associated with human contact.
- Quiet Operation: The machine operates at low noise levels, creating a more comfortable working environment for operators during extended production runs. This is particularly valued in facilities where multiple machines operate in close proximity.
Working Principle: Continuous Vertical Sachet Forming
The Ry-150KLB-F forms sachets through a continuous vertical process that integrates forming, filling, and sealing in a single material pass:
- Film Feeding: The composite film roll unwinds and feeds into the forming collar, which shapes the flat film into a vertical tube. The forming collar geometry determines the final bag width and is selected based on the target sachet dimensions.
- Back Seal Creation: The vertical sealing jaws apply heat and pressure along the overlapping film edges, creating a continuous back seal that runs the full length of the tube. The independent temperature controller maintains the sealing jaw at the optimal temperature for the specific film material in use.
- Bottom Seal and Fill: The horizontal sealing jaws close to form the bottom seal of the new bag. Simultaneously, the dosing system dispenses the programmed volume of granules or powder into the formed pouch through the central filling tube.
- Top Seal and Cut: The horizontal jaws close again to seal the top of the filled bag and form the bottom seal of the next bag in the same motion. A cutting blade separates the finished sachet from the continuous film tube.
- Discharge: The completed sachet drops onto the outfeed conveyor for collection, cartoning, or transfer to secondary packaging equipment.
The PLC synchronizes the timing of film feeding, sealing jaw actuation, and product dosing to maintain consistent sachet dimensions and fill accuracy across the full speed range.
Granule Packaging Applications
The Ry-150KLB-F is specifically optimized for granular products that flow freely and can be dosed volumetrically:
- Pharmaceutical granules: Wet-granulated and dry-granulated drug substances in unit-dose sachets for clinical trials, hospital dispensing, and retail pharmacy distribution.
- Nutraceuticals: Protein granules, electrolyte mixes, amino acid supplements, and herbal granule preparations.
- Food products: Sugar, salt, coffee granules, seasoning blends, soup mixes, desiccant packets, and confectionery portions.
- Agricultural products: Seed portions, fertilizer granules, and soil amendment samples.
- Chemical products: Detergent granules, water treatment chemicals, and industrial additive portions.
Film Material Compatibility
The machine processes standard heat-sealable composite films used in sachet packaging:
- OPP/CPP: Clear, economical film for products where visual inspection of contents is desired. Good moisture barrier for dry granules.
- OPP/CE: Stiffer film structure for sachets that need to maintain a flat, rigid shape on retail shelves. Excellent print surface for branded packaging.
- PET/PE: Superior oxygen barrier for products sensitive to oxidation, including pharmaceutical active ingredients and nutritional compounds with limited shelf life when exposed to air.
- Custom composites: Aluminum foil laminates and high-barrier multi-layer films can be processed for products requiring maximum protection from moisture, oxygen, and light.
Quality Standards and Compliance
Each Ry-150KLB-F unit is manufactured under ISO 9001:2015 certification and carries CE marking for international compliance. The machine uses SUS304 stainless steel for the frame and product-contact surfaces, meeting GMP-oriented pharmaceutical production requirements. The enclosed material handling system supports cleanroom-compatible operation for pharmaceutical and biotechnology applications.
