The Ry-400KLB-L is a vertical form-fill-seal (VFFS) packaging machine engineered for high-speed sachet and bag production across pharmaceutical, food, chemical, and consumer goods industries. With a packing speed of 25 to 75 bags per minute and a measuring range of 1 to 500 milliliters, the machine handles granules, powders, and small solid items in bag sizes up to 500 mm long and 400 mm wide. A PLC control system with an English-language interface manages the entire production cycle, from film feeding and bag forming through filling, sealing, date coding, and finished product discharge.
The vertical architecture saves floor space compared to horizontal packaging systems while maintaining full automation of every production stage. The closed loading, unloading, and packaging chambers prevent dust contamination during operation, making the machine suitable for environments where airborne particle control is a regulatory or quality requirement.

Key Features
- Touch Screen Parameter Control: All operational parameters, including bag length, filling volume, sealing temperature, and production speed, are adjustable through the touch screen interface. Operators can fine-tune settings during production without stopping the machine, reducing changeover-related downtime.
- PLC Control with Low Failure Rate: The programmable logic controller manages all machine sequences, from film feeding through product discharge. The centralized control architecture reduces component count and interconnection complexity, resulting in a documented low failure rate under continuous production conditions.
- Independent Temperature Control (plus or minus 1 degree Celsius): Each sealing jaw maintains its own temperature control loop with accuracy of plus or minus 1 degree Celsius. This precision prevents seal failures caused by temperature drift and ensures consistent seal integrity across different film materials and production speeds.
- Frequency Converter with Auto-Open Sealing Knife: When the machine shuts down, the frequency converter automatically opens the sealing knife to prevent heat damage to the film at the seal position. This feature saves packaging material that would otherwise be scrapped after each stoppage, accumulating meaningful material cost savings over a production year.
- Closed Material Handling System: Loading, unloading, and packaging operations are enclosed within sealed chambers to prevent dust from escaping into the production environment. This design is particularly important for powder and granule packaging, where airborne particles can contaminate adjacent equipment and create workplace air quality concerns.
- Single-Pass Complete Operation: Measurement, bag forming, filling, sealing, date printing (optional), and product output are completed in one continuous pass. No intermediate handling or manual intervention is required between stages.
- Low-Noise Operation: The machine is engineered for quiet operation, contributing to a more comfortable working environment for line operators during extended production shifts.
Working Principle: Vertical Form-Fill-Seal Process
The vertical packaging process follows a continuous sequence that forms, fills, and seals each bag in a single pass through the machine:
- Film Feeding and Tube Forming: The packaging film roll is unwound and fed through a forming collar that shapes the flat film into a continuous tube. The vertical sealing jaws create the back seal along the length of the tube, establishing the bag's longitudinal closure.
- Bottom Seal Formation: The horizontal sealing jaws close to seal the bottom of the upcoming bag while simultaneously cutting the top seal of the previous bag. This dual-action sealing approach ensures continuous production without pause between bags.
- Product Filling: The measured quantity of product, whether granules, powder, or small items, is dispensed into the formed pouch through the filling tube. The dosing system, calibrated to the programmed volume, delivers consistent fill weights from bag to bag.
- Top Seal and Cut: After filling, the horizontal sealing jaws close again to seal the top of the filled bag and form the bottom seal of the next bag. The cutting mechanism separates the finished bag from the continuous film tube.
- Product Discharge: The finished, sealed bag is discharged onto the outfeed conveyor for collection, cartoning, or downstream processing.
The PLC system coordinates the timing of each stage to maintain consistent bag dimensions, seal quality, and fill accuracy across the full speed range of 25 to 75 bags per minute.
Compatible Packaging Materials
The Ry-400KLB-L processes a range of heat-sealable composite films commonly used in pharmaceutical, food, and industrial packaging:
- OPP/CPP: Oriented polypropylene with cast polypropylene, suitable for food products requiring good moisture barrier and clear film appearance.
- OPP/CE: Oriented polypropylene with cellulose ester, offering enhanced stiffness and printability for retail consumer packaging.
- PET/PE: Polyester with polyethylene, providing excellent oxygen barrier properties for products sensitive to oxidation, including pharmaceutical powders and nutritional supplements.
- Other composite materials: Custom film structures can be accommodated based on specific product requirements for barrier performance, seal strength, and shelf appearance.
Applications Across Industries
- Pharmaceuticals: Powder and granule medications in unit-dose sachets, effervescent tablet packaging, and herbal preparation pouches.
- Food and Beverage: Coffee, tea, sugar, seasonings, snacks, dried foods, and powdered drink mixes in retail-ready sachets and bags.
- Nutraceuticals: Protein powders, meal replacement sachets, vitamin mixes, and dietary supplement portions.
- Chemicals: Detergent powders, agricultural chemicals, water treatment compounds, and industrial powders requiring moisture-resistant packaging.
- Cosmetics: Sample sachets for creams, lotions, shampoos, and personal care products.
