C18 Inner and Outer Herbal Tea Bag Packing Machine

The C18 automatically forms, fills and seals inner and outer tea bags from a single machine, running 40 to 60 bags per minute at 3 to 15 ml per bag. It is designed for herbal, medicinal and health tea producers who need to package small granular blends in a two-layer structure with a thread and tag. The machine forms both inner and outer bags simultaneously, uses a measuring cup filler, and supports photoelectric positioning for tag placement. It runs on 220V 50Hz power with a 3.7 kW motor and fits in a compact footprint.

Forms inner and outer bags at the same time, reducing handling and contamination risk
Photoelectric positioning ensures consistent tag placement on every bag
Measuring cup filling delivers repeatable volume across 3 to 15 ml per bag
Adjustable inner and outer bag sizes to match different product formats and branding needs

Key Benefits

Forms inner and outer bags at the same time, reducing handling and contamination risk
Photoelectric positioning ensures consistent tag placement on every bag
Measuring cup filling delivers repeatable volume across 3 to 15 ml per bag
Adjustable inner and outer bag sizes to match different product formats and branding needs

Application Scenarios

Herbal tea producers packaging ginseng, chrysanthemum and goji berry blends in branded two-layer bags
Medicinal tea manufacturers running small batches of multiple formulas with consistent tag alignment
Health tea brands needing a clean, professional appearance with a visible thread and tag
Contract packers handling multiple private label herbal tea lines with quick format changeover

Who It Is For

Herbal and medicinal tea producers moving from manual packing to automated inner and outer bagging
Brands that require a thread and tag on the outer bag for consumer convenience and brand recognition
Producers who need to package small granular blends without dust or spillage during filling
Buyers replacing a two-machine setup with a single integrated inner and outer bagging line

Problems It Solves

Manual inner and outer bagging causes inconsistent fill volume and high labor cost
Separate machines for inner and outer bagging increase footprint and alignment errors
Tag placement is inconsistent when done by hand or with non-photoelectric systems
Small granular blends spill during transfer between separate forming and filling stations
Lack of adjustable bag size limits the ability to match different product formats and packaging designs

Customization Options

Inner and outer bag sizes adjusted to fit specific product dimensions and branding
Tag size and position set according to customer's design requirements
Thread and tag attachment enabled or disabled based on order
Power supply configured to match destination market voltage and plug type
Packaging material type selected from available options including composite and aluminum laminates

How It Compares

Separate inner and outer bag machines	The C18 combines both steps into one line, reducing footprint and alignment errors, but requires a single machine setup for both layers
Manual inner and outer bagging	The C18 replaces hand assembly and ensures consistent fill and tag placement, but requires a trained operator and fixed power supply
Single-layer tea bag machine	The C18 provides a protective outer layer and branded tag, but uses more material and requires more setup time

Use Guide

1Connect a single phase 220V 50Hz power supply and ensure a stable voltage
2Load the inner and outer bag film rolls according to the selected material type
3Set inner bag size to 50-70 mm length and 40-80 mm width, outer bag to 70-120 mm length and 60-90 mm width
4Adjust the measuring cup to the desired fill volume between 3 and 15 ml
5Enable or disable thread and tag attachment based on product needs
6Run a test batch of 10 bags and check fill volume, seal integrity and tag position before full production
