Tea Filling Machine——Tea Bag & Small Sachet Packaging System
Tea packaging is not limited to bottled beverages. A large portion of the tea industry relies on small-dose packaging formats, including tea bags, filter sachets, inner pouches, and single-serve portion packs. These products require a completely different type of equipment compared to liquid filling systems.
The Tea Filling Machine developed by MIC Machinery is designed specifically for dry tea products such as loose-leaf tea, herbal blends, flower tea, and functional tea powders. The system focuses on accurate weighing, clean bag forming, and stable high-speed packaging rather than liquid metering.
In real production environments, consistency of weight, sealing quality, and material protection are more important than filling speed alone.
The tea packaging process is designed to ensure accurate weighing and clean sealing without damaging tea leaves or producing excess dust.
Material Feeding
Loose tea or blended herbs are fed into the hopper system. For powder-based tea products, an auger feeding system is used to maintain stable material flow.
Weighing or Dosing
A multi-head weighing system calculates the target weight for each sachet. For fine powders, auger dosing ensures stable measurement even when density fluctuates.
Bag Forming
Packaging film is automatically shaped into small bags or sachets. Depending on product requirements, pyramid tea bags or flat filter bags can be produced.
Filling Process
The measured tea is filled into each formed bag. Dust control systems reduce airborne particles during filling, keeping the working environment clean and stable.
Sealing and Cutting
Each bag is sealed using heat or ultrasonic sealing technology. The sealing method is selected based on packaging material and desired shelf life. After sealing, individual tea bags are cut and discharged automatically.
Secondary Packaging (Optional)
Finished tea bags can be grouped into inner boxes or outer cartons depending on production requirements.

Applications
The Tea Filling Machine is widely used in tea processing and herbal product industries.、
The system is suitable for both mass-market tea production and high-end specialty tea brands.
Machine Overview
Tea filling systems are generally based on automatic weighing and packaging technology, not volumetric liquid filling. Depending on product form, the machine can be configured for pyramid tea bags, flat filter bags, or small inner sachets packed into outer envelopes.
MIC Machinery designs the system around multi-head weighing units or auger dosing systems for fine tea particles and powder blends. The equipment ensures that each bag contains a precise amount of tea, even when particle size or density varies between batches.
All product-contact parts are made of food-grade stainless steel to maintain hygiene standards. The structure is designed to minimize dust dispersion, which is a common issue in dry tea packaging lines.
For high-end tea products, nitrogen flushing and aroma protection systems can also be integrated to preserve freshness during sealing.
Customization Options
Tea packaging requirements vary significantly depending on product type and branding needs. MIC Machinery provides multiple customization options.
Pyramid Tea Bag System
Supports three-dimensional tea bags that improve infusion quality and visual presentation.
Nitrogen Flushing System
Helps preserve aroma and prevent oxidation in premium tea products.
Dust Collection System
Reduces airborne tea particles during filling, improving hygiene and working conditions.
Multi-Head Weighing Upgrade
Increases accuracy and production speed for large-scale operations.
Different Sealing Technologies
Heat sealing or ultrasonic sealing can be selected depending on filter material.
Secondary Packaging Integration
Can be connected to cartoning machines or overwrapping systems for retail-ready packaging.
Custom Bag Size Adjustment
Supports different tea bag sizes without major mechanical modification.
Maintenance
Tea filling systems handle dry and often dusty materials, so regular cleaning is essential for stable operation.
Daily maintenance includes cleaning hoppers, removing residual tea dust, and checking sealing temperature stability. Accumulated dust can affect weighing accuracy if not removed regularly.
Weekly inspection should focus on dosing system calibration, sealing unit condition, and sensor alignment. For auger systems, screw wear should also be monitored.
Electrical and pneumatic systems should be checked regularly to ensure consistent operation in high-speed production environments.
With proper maintenance, the system maintains stable accuracy and sealing quality over long production cycles.
