Automatic Inner and Outer Tea Bag Packing Machine with Thread and Tag

Product Overview

This automatic tea bag packaging system completes both the filter paper inner bag and the protective outer envelope on one machine. It is intended for small particulate products such as tea leaves, herbal tea blends, cut roots, and similar dry steeping materials within the confirmed measuring range.

The inner and outer films are advanced by stepper motors to support stable bag length and accurate positioning. A PLC coordinates the machine sequence through a human-machine interface, while PID temperature control manages the sealing temperature. During production, the machine measures the product, forms and fills the inner filter bag, applies the thread and tag configuration, seals and cuts the inner bag, then encloses it in a composite-film outer bag. These functions and packaging materials are confirmed in the supplied specification.

This format is suitable for tea processors, herbal infusion manufacturers, private-label packers, and factories that need individually wrapped tea bags for retail cartons, hospitality supply, or sample packs. Combining the inner and outer packaging stages reduces separate handling between machines and supports a more organized production flow. Final suitability should be checked for long fibers, irregular pieces, high moisture, excessive oil, or products that do not feed consistently.

Applications

This machine is suitable for dry, small-cut, granular, or particulate steeping materials that can be measured consistently and filled into filter paper inner bags. Particle size, flowability, moisture content, fiber length, and bulk density should be evaluated before confirming the final configuration.

This machine is suitable for:

• Black tea fannings
• Green tea particles
• Oolong tea particles
• Jasmine tea blends
• Rooibos tea
• Herbal tea granules
• Cut peppermint leaves
• Chamomile flower pieces
• Roasted barley tea
• Small-cut botanical roots
• Dried flower and leaf blends
• Fruit and herbal infusion blends
• Coarse ground coffee for infusion bags

A material test is recommended for products containing long fibers, excessive powder, high moisture, irregular pieces, strong oil content, poor flowability, or a tendency to bridge inside the feeding system.

Main Features

1. Integrated Inner and Outer Packaging

The machine forms, fills, seals, and cuts the filter paper inner bag before automatically enclosing it inside an individual composite-film outer envelope.

2. Thread and Tag Tea Bag Configuration

Filter paper, cotton thread, labels, and composite film are included in the documented packaging material system for producing individually wrapped tagged tea bags.

3. Stepper Motor Film Control

Separate stepper motor control for the inner and outer films helps maintain stable bag length and supports accurate packaging material positioning during production.

4. PLC and HMI Operation

The complete operating sequence is coordinated by a PLC, while the human-machine interface allows operators to view and adjust relevant production settings.

5. PID Temperature Regulation

The sealing temperature is managed through a PID temperature controller, supporting more stable heat control when processing filter paper and composite packaging film.

6. Adjustable Inner and Outer Bags

The machine supports adjustable inner and outer bag dimensions within the confirmed ranges, allowing packaging specifications to be matched to different product portions.

7. Three-Side-Sealed Package

The documented sealing format is three-side sealing, creating individual inner and outer packages suitable for tea and herbal infusion products.

8. Continuous Packaging Output

The confirmed production speed is 30–40 bags per minute, subject to product flowability, filling volume, bag dimensions, and packaging material performance.

9. Optional Coding Equipment

A coding machine is listed as an optional configuration for adding production dates, batch numbers, or other required information to the outer package.

Working Principle

The dry product is supplied to the feeding and measuring section, where the preset dose is prepared within the confirmed range. Filter paper is drawn into the inner bag-forming section while the thread and tag materials are fed through their corresponding units. The measured product enters the formed inner bag, which is then sealed and cut.

The completed inner tea bag is transferred to the outer packaging section. Composite film is drawn to the required length, formed around the inner bag, sealed, and cut into an individual outer envelope. Stepper motors control inner and outer film movement, while the PLC coordinates the operating sequence and the PID controller regulates sealing temperature. The finished wrapped tea bag is then discharged for collection or secondary carton packing.

Process Flow:

Product Feeding → Measuring → Inner Filter Bag Forming → Filling → Thread and Tag Application → Inner Bag Sealing and Cutting → Outer Film Forming → Outer Bag Sealing and Cutting → Discharge

Machine Details

1. Product Feeding and Measuring Section

This section receives tea, herbal particles, or similar dry materials and measures the required portion before the product enters the inner filter bag.

2. Inner Filter Paper Feeding System

The inner film system unwinds and advances tea filter paper according to the selected bag length before it reaches the forming and filling section.

3. Thread and Tag Feeding Unit
