Keypack Intelligent Triangle Tea Bag Packing Machine designed for high-speed automated tea packaging with ultrasonic sealing technology. It delivers 50-80 bags per minute with ±0.15g metering accuracy using a 6-head electronic weigher system and Siemens PLC control. Ideal for green tea, herbal tea, flower tea, fruit tea, traditional Chinese medicine tea, and specialty coffee packaging in pyramid and flat four-corner bag formats.
Product Overview
This vertical form-fill-seal machine (VFFS Machine) combines precision engineering with user-friendly automation for tea bag sealing operations. The pyramid tea bag packing machine features ultrasonic sealing technology that creates aesthetically superior triangle pyramid bags and flat four-corner pouches with hermetic seal integrity. Unlike traditional heat-sealing methods, ultrasonic sealing preserves material quality while producing visually flawless seams on nylon mesh, non-woven fabric, and biodegradable corn fiber materials.
The Keypack Intelligent (Kunbupack) Tea Triangular Bag Vertical Machine integrates a high-precision 6-head tea weigher with Siemens PLC touchscreen control, enabling real-time production monitoring and one-touch format switching between 3D triangular pyramid forming and flat bag configurations. The integrated machine-pneumatic architecture allows parameter adjustments during production without shutdown, maximizing overall equipment effectiveness and reducing changeover time.
Engineered with premium Airtac pneumatic components and Schneider electrical elements, this vertical packaging machine delivers reliable performance for contract packaging operations, private label tea brands, export-oriented production, and high-end tea beverage packaging applications requiring GMP-compliant quality standards.

Key Features and Machine Characteristics
1. Ultrasonic Sealing Technology for Superior Bag Quality
The triangular tea bag machine employs ultrasonic sealing and cutting to produce aesthetically superior pyramid tea bags with strong, hermetic seals. This non-heat sealing method prevents material damage and creates visually flawless seams that enhance brand perception and consumer confidence. Compatible with nylon mesh, non-woven fabric, and corn fiber materials for raw leaf triangular tea bags and herbal tea triangular bags.
2. High-Precision 6-Head Electronic Weigher System
The automated tea packaging system features a 6-head electronic scale that delivers ±0.15g metering accuracy across the 1-10g fill range. The automatic quantitative metering method allows easy fill-weight adjustments during production without stopping the machine, reducing product giveaway and ensuring compliance with weight-labeling regulations for export markets.
3. Siemens PLC Control with Touchscreen Interface
Industrial-grade Siemens PLC control system with intuitive touchscreen operation provides enhanced stability, simplified operation, and user-friendly performance. Real-time production monitoring, recipe storage, and diagnostic capabilities enable consistent quality control and rapid troubleshooting for tea bag sealing machine operations.
4. Premium Component Integration for Extended Service Life
Engineered with Airtac pneumatic components and Schneider electrical elements to extend machine service life and deliver reliable uptime. The integrated machine-pneumatic architecture enables data changes without shutdown, maximizing productivity during multi-SKU production runs.
5. One-Touch Format Switching Between Bag Styles
Switch between 3D tea bag packaging (triangle pyramid bags) and flat four-corner pouches with one-touch operation. This production flexibility accommodates diverse product lines without tooling changes, reducing changeover time and enabling rapid response to market demands for different bag formats.
6. Thread and Tag Attachment Capability
When using thread-and-tag materials, the vertical form-fill-seal machine can produce traditional hanging tea bags with attached strings and labels. This versatility supports both premium pyramid tea bag formats and conventional hanging tea bag styles within a single platform.
Application Areas
This Tea Packaging Machine excels across diverse beverage and wellness product packaging applications:
Premium Tea Processing:
Green tea, black tea, oolong tea, white tea, and specialty blends requiring pyramid bag presentation for whole-leaf expansion. The 3D triangular pyramid forming provides sufficient space for tea leaves to fully expand during hot water brewing, maintaining original flavor and natural aroma. Suitable for loose-leaf tea in granular and strip-shaped forms.
Herbal and Flower Tea Packaging:
Flower tea, herbal tea triangular bags, fruit tea, ginseng tea, and eight-treasure tea blends. The transparent nylon mesh or non-woven materials allow consumers to clearly see the tea ingredients, building trust and confidence. Nitrogen-filled fresh-keeping options available for extended shelf life.
Functional Wellness Beverages:
Traditional Chinese medicine tea, health tea, detox tea blends, and therapeutic infusions requiring precise dosing and food-grade packaging materials. The high-precision electronic weigher ensures accurate fill weights for regulatory compliance and consistent therapeutic dosing.
Specialty Coffee and Flavored Tea:
Single-origin coffee sachets, cold brew bags, flavored tea triangular bags, and specialty coffee blends in pyramid format for enhanced extraction. The ultrasonic sealing preserves aromatic compounds and prevents flavor degradation during storage.
Contract Packaging and Private Label Production:
High-volume manufacturing for private label tea brands, hotel amenity programs, gift set production, and export-oriented operations requiring consistent quality and attractive presentation. The machine supports high-end tea beverage packaging standards with GMP-compliant construction.
Multi-Format Production Capabilities:
The vertical packaging machine handles granular and strip-shaped tea materials including loose-leaf green tea, cut herbal ingredients, fruit pieces, and coffee grounds. Material compatibility extends to products with varying bulk densities and particle sizes within the 1-10g metering range.
Pyramid Tea Bag Advantages
The 3D tea bag packaging format offers distinct benefits over traditional flat tea bags:
-
Enhanced Infusion Space: After hot water brewing, the pyramid structure provides ample space for whole-leaf tea, herbal tea, ginseng tea, and fruit tea to fully expand, preserving original tea flavor and natural aroma.
-
Multiple Brewing Cycles: The robust ultrasonic seals withstand multiple infusions and extended steeping without bag damage or material degradation.
-
Visual Product Transparency: Transparent packaging materials enable consumers to clearly inspect tea leaf quality and ingredient composition, building purchase confidence.
-
Food-Grade Safety Compliance: All packaging materials undergo rigorous food safety testing to ensure hygienic, safe contact with consumable products.
