Nylon Triangle Tea Bag Packaging Machines

Say Goodbye to Traditional Flat Bags and Tea Crushing: Create an Ultra-Fast, Crystal-Clear Packaging Experience with High-End Nylon Pyramid Bags

The Nylon Pyramid Tea Bag Packaging Machine (with Thread and Label Series) is an industrial-grade, high-efficiency automation assistant built specifically to solve premium tea packaging pain points, such as poor tea expansion in flat bags, leaf crushing, mesh burns from thermal sealing, weak thread/label adhesion, and low aesthetic appeal.

LANTU Machinery introduces tailored, full-line automated nylon pyramid tea bag packaging solutions. Featuring precision mechanical linkage drives, high-precision micro multi-head electronic scale or volumetric cup dosing, food-grade ultrasonic seamless welding, and automatic thread-and-label integration, the machine operates across five core stations (1. Precision Whole-Leaf Tea Dosing $\rightarrow$ 2. Nylon Mesh Pulling & Thread/Label Positioning $\rightarrow$ 3. 3D Pyramid Ultrasonic Forming & Sealing $\rightarrow$ 4. Precision Cutting & Thread Attachment $\rightarrow$ 5. Finished Output & Counting). It functions like an expert dedicated to tea packaging. Whether processing whole-leaf teas, botanical herbal blends, fruit teas, coarse herbal cuts, or wellness teas, it realizes end-to-end integration: automatic dosing, mesh wrapping, ultrasonic seamless welding, 3D pyramid forming, and clean cutting with zero leaf crushing, zero bag leakage, crystal-clear transparency, and no manual contact required.

As a direct source packaging machinery manufacturer, LANTU Machinery makes this complex process—whole-leaf dosing, nylon mesh ultrasonic welding, 3D pyramid orientation change, thread-and-label attachment, and high-frequency ultrasonic cold cutting—as intuitive as using a smartphone. Operators simply adjust bag length and running parameters on the PLC touchscreen and load bulk tea into the hopper. The machine automatically manages dosing, 3D pyramid forming, and product output. Accommodating a wide range of bag dimensions and fill capacities, this machine drastically shortens packaging cycles while saving labor, time, and operating costs.

Choosing a reputable source manufacturer is crucial for your return on investment. LANTU Machinery’s mature 3D pyramid forming and ultrasonic welding technologies deliver high reliability and material efficiency to keep your tea packaging line running without interruption.

Core Components & Three Key Systems (LANTU Precision Parts)

Our Nylon Pyramid Tea Bag Packaging Machine is built with industry-leading components to ensure high quality, zero defects, and extended machine lifespan.

1.Intelligent Dosing, Nylon Mesh Forming & Ultrasonic Welding System

Precision Micro Electronic Multi-Head Scale Dosing: Purpose-built 4-head/10-head micro electronic combination scales for whole-leaf tea provide millisecond response times and smooth, corner-free channels that prevent leaf tearing.

Japanese-Technology Ultrasonic Welding Unit: Utilizes high-frequency ultrasonic sealing technology without thermal glues. Seal seam widths are under 1mm, producing fine, firm, and odorless seals that withstand brewing without splitting.

One-Touch 3D Pyramid / Flat Bag Conversion Device: Innovative adjustable orientation formers allow operators to switch between “3D Pyramid Bags” and “Flat 4-Corner Mesh Bags” via touchscreen parameter selection or minor mechanical adjustment.

2.Integrated Thread/Label & Precision Film Pulling System

Automated Thread/Label Ultrasonic Spot Welding: Nylon mesh and pre-threaded label materials align with precision while ultrasonic spot welders attach cotton threads and labels securely to the mesh without detaching during pulls.

Servo Film Pulling & Optical Eye-Mark Tracking: Servo motors control nylon mesh pulling while high-sensitivity optical sensors register eye-marks and label positioning for exact alignment.

No Tea No Film Pulling / No Material Cutting Protection: Real-time sensors monitor dosing states. Film pulling and cutting pause automatically if tea is absent, eliminating mesh and label waste.

3.Central Control & Safety Protection System

Siemens / Mitsubishi PLC Central Controller: Industrial-grade multi-core CPU provides centralized line control, stable operation, anti-interference capabilities, and multi-language support.

One-Touch Specification Change & Modular Design: Changing bag dimensions or loading new mesh rolls is fast and simple, with modular structures enabling changeovers in minutes.

Fully Enclosed Safety Guarding: Thickened transparent safety doors stop operation instantly when opened, meeting GMP and food hygiene standards while protecting operator safety.

Technical Specifications

Note: Actual packaging speed depends on tea bulk density, flowability, dosing system, and mesh material. Custom engineering options are available upon request.

Complete Nylon Pyramid Tea Bag Packaging Workflow

Station 1 (Whole-Leaf Tea Precision Dosing): Whole-leaf tea is accurately weighed by micro electronic scales and glides down inclined buffer chutes into the forming zone without leaf breakage.

Station 2 (Mesh Pulling & Thread/Label Positioning): Servo film pulling systems draw pre-threaded nylon mesh while optical sensors register exact label and thread locations.

Station 3 (Ultrasonic Longitudinal & Bottom Sealing): High-frequency ultrasonic welding horns close to execute continuous seamless seals along the nylon mesh edges, forming a mesh tube.

Station 4 (3D Pyramid Orientation Conversion & Top Sealing): Orientation mechanisms rotate 90 degrees to shape the mesh tube into a 3D pyramid structure before ultrasonic horns execute top seals.

Station 5 (Ultrasonic Cold Cutting & Product Output): Ultrasonic cutters cleanly sever bag edges to produce crystal-clear 3D pyramid tea bags delivered via discharge conveyors.

Key Factors to Consider When Purchasing a Nylon Pyramid Tea Bag Machine

To select the ideal machine configuration for your production line, evaluate the following key purchasing metrics:

Tea Leaf Morphology & Dosing Method:

Whole-leaf tea / large herbal pieces / fruit cubes: Must choose micro electronic combination scales to prevent clogging and crushing.

Fine particles / uniform herbal teas: Choose electronic weighing or volumetric cup systems.

Mesh Material Type: Nylon mesh, PET mesh, or biodegradable PLA corn fiber mesh (determines ultrasonic horn frequency and power configuration).

Thread and Label Requirement: Confirm whether thread-and-label integration is required or if plain pyramid bags are sufficient.

Target Output (bags/min): Match required output (e.g., 30–50 bags/min) to determine optimal ultrasonic response speed and servo film pulling setup.

Downstream Envelope Module Integration: Evaluate needs for connecting with outer envelope machines or automated cartoning lines.

Frequently Asked Questions (FAQ)

Q1: Can the nylon pyramid machine run biodegradable PLA corn fiber mesh?

A: Fully supported. Our frequency-tuned ultrasonic welding system supports traditional Nylon and PET mesh as well as eco-friendly PLA corn fiber mesh, delivering strong seals without film damage.

Q2: Will whole tea leaves get crushed or clogged in the dosing chute during packaging?

A: No. We equip specialized micro multi-head scales with inclined buffer chutes designed specifically for whole-leaf tea. Smooth, wide-aperture channels allow leaves to glide into mesh bags by gravity, preserving leaf integrity.

Q3: Can the machine switch between 3D pyramid bags and flat bags? Is adjustment complex?

A: Switches are seamless. Equipped with patented orientation conversion mechanisms, operators select bag formats on the PLC touchscreen and adjust cutter angles in minutes to switch between 3D pyramid and flat formats.
