Tea Bag Making Machine | High-Speed Packaging Equipment
Empowering global beverage packagers with ultra-precise volumetric dosing, ultrasonic pyramid and flat sachet forming, integrated string and tag attachment, and smart automated outer envelope sealing.
Advanced High-Speed Tea Bag Packaging Solutions
The international beverage packaging market demands absolute consistency, aroma preservation, and rigorous hygiene standards. Ludyway designs and manufactures industrial-grade tea bag making machines engineered to process broad spectrums of dry beverage ingredients—from broken orange pekoe and whole-leaf artisan botanicals to superfine herbal powders, matcha blends, and dehydrated fruit infusions.
Our automated equipment integrates electronic micro-weighing, servo-driven rotary web indexing, ultrasonic cold-sealing mechanics, and multi-axis robotics. By combining inner envelope manufacturing, automated string and tag fastening, and hermetic outer foil packaging into a seamless, synchronized workflow, Ludyway packaging lines eliminate operational bottlenecks while driving down unit manufacturing costs.
Industrial Efficiency Benchmark: Engineered with medical-grade 304/316 stainless steel contact surfaces and PLC multi-axis synchronization, our tea bag packaging systems maintain weight tolerances within ±0.1g while delivering sustained operational speeds of up to 120-200 sachets per minute with minimal roll waste.
Key Architectural & Technological Features
Ultrasonic Sealing Matrix
Utilizes advanced high-frequency ultrasonic transducers to achieve clean, aesthetic perimeter bonding on non-woven fabrics, PLA mesh, and nylon without adhesive degradation or thermal material scorching.
Multi-Lane Volumetric Dosing
Configured with quick-release telescopic measuring cups and high-accuracy vibratory chutes, accommodating leaf volume variances, loose botanicals, and high-density powder formulations flawlessly.
Hermetic Nitrogen Gas Purge
Integrated nitrogen flush functionality displaces residual chamber oxygen below 1% inside outer film envelopes, radically preventing essential oil oxidation and securing extended retail shelf stability.
Automated String & Tag Infeed
Fully automatic thread feeding, cold-punch knotting, and ultrasonic tag application eliminate manual interventions while ensuring consistent tensile pull-strength on delicate filter mediums.
Integrated Secondary Enveloping
Directly synchronizes inner filter pouch transfer to horizontal outer wrapping modules, producing clean 3-side or 4-side sealed barrier pouches with optional easy-open tear notches.
Intelligent PLC Touch Controls
Centralized color HMI provides real-time bag count, cycle diagnostics, optical photo-eye tracking calibration, temperature monitoring, and multi-recipe program retention.

1. Filter Substrate Compatibility: PLA Cornfiber, Nylon, and Filter Paper
When choosing a commercial tea packaging line, selecting the correct feeding mechanism and sealing technology depends largely on the filter mesh substrate. Eco-conscious global markets increasingly favor Polylactic Acid (PLA) mesh sourced from 100% biodegradable plant starches. Because PLA has a narrow melting and molecular bonding point compared to standard plastics, conventional heated sealing bars cause fraying, weak seam integrity, and aesthetic defects.
Ludyway engineers incorporate ultrasonic sonotrodes tuned to 20-35 kHz with dynamic amplitude control. This generates instantaneous localized vibrational heat that bonds PLA mesh or woven nylon seamlessly within milliseconds without scorching the delicate tea aroma or imparting synthetic smells.
2. Preservation of Whole Botanical Geometry and Volatile Aromatics
Standard high-speed auger or screw fillers frequently break delicate, large-cut whole leaves, dried rose petals, and jasmine buds during mechanical transfer. Degrading the leaf size not only diminishes visual consumer appeal inside translucent pyramid bags, but also accelerates tea dust creation, which can compromise the sealing perimeter.
To safeguard structural botanical integrity, Ludyway implements low-friction multi-head vibratory weighers paired with smooth sliding hoppers. Gentle optical metering and programmable feeding angles ensure large-leaf artisan teas, oolong pearls, and herbal tisanes maintain intact physical form from loading to individual bag release.
3. Integrated Downstream Automation: From Single Pouches to Finished Cartons
High-speed packaging line profitability relies on minimizing manual touchpoints between initial dosing and final pallet loading. Modern turnkey operations benefit from integrated automation architectures that unite:
- Dynamic Rotary Bag Pick-and-Place: High-speed vacuum articulators that transfer inner tea sachets into individual high-barrier outer pouches at zero drop-height to eliminate leaf agitation.
- Automated Counting & Collation: Batch grouping modules that accurately stack 10, 20, or 50 individual sachets into collated lots ready for cartoning.
- Automatic End-of-Line Cartoning: Horizontal continuous-motion cartoners that erect retail boxes, insert grouped sachets with product brochures, and hot-melt glue seal the carton flaps.
- Integrated Quality Control: High-resolution dynamic checkweighers, inline nitrogen concentration testers, and industrial metal detectors for fail-safe rejection.

Common Technical & Operational Inquiries
Can a single Ludyway machine switch between pyramid and flat tea bags?
Yes. Our flagship pyramid packaging lines feature one-touch digital changeover on the PLC touch screen. The servo-driven sealing jaws automatically adjust their mechanical sealing angles, allowing seamless transitions between 3D pyramid (triangle) bags and conventional flat sachets without replacing mechanical parts.
How does ultrasonic sealing compare to heat-sealing for biodegradable PLA?
Ultrasonic sealing uses high-frequency acoustic vibrations that generate molecular friction strictly at the contact joint, instantly melting and bonding PLA fibers. Heat-sealing relies on continuous thermal transfer, which easily warps, shrinks, or discolors PLA mesh and can degrade heat-sensitive volatile tea compounds.
What options are available for string, tag, and envelope branding?
Our equipment supports custom pre-printed tags welded directly to food-grade cotton string or ultrasonic tag attachments during roll feed. For the secondary packaging stage, our outer envelope wrapper supports photocell print registration, nitrogen flush, batch coding, tear notch stamping, and custom envelope sizing.
What post-sale technical support and commissioning does Ludyway provide?
Ludyway provides complete on-site engineering installation, commissioning, and operational training globally. Additionally, we provide 24/7 remote diagnostic support via encrypted industrial IoT gateways, a lifetime supply of replacement components, and comprehensive multilingual video documentation.
