C18 Automatic Black Tea Small Scale Tea Bag Machine

The C18 automatically forms, fills and seals inner and outer tea bags from filter paper and composite film materials, running 40 to 60 bags per minute at 3 to 15 ml per bag. It is designed for small-scale tea producers and blenders who need consistent packaging of black tea, medicinal tea and health tea in a sealed outer envelope with a threaded tag. The machine forms both inner and outer bags simultaneously, uses photoelectric positioning for tag alignment, and supports multiple material combinations including paper, plastic and aluminum layers.

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

Key Benefits

Forms inner and outer tea bags at the same time, reducing manual handling and contamination risk
Photoelectric positioning ensures accurate tag placement on every bag
Adjustable inner and outer bag sizes to match different product formats and branding needs
Volumetric cup filling delivers consistent fill volume across 3 to 15 ml range
Supports multiple material layers including paper, plastic and aluminum for barrier and shelf-life needs
Thread and tag attachment is optional, allowing flexible configuration for different market requirements

Application Scenarios

Small tea producers packaging black tea in branded outer envelopes for retail sale
Medicinal tea manufacturers needing sealed outer packaging for product safety and shelf appeal
Health tea brands running short batches with varying bag sizes and tag designs
Contract packers handling multiple tea lines with quick format changeover between products

Who It Is For

Small to medium tea producers moving from hand packing to automated inner and outer bagging
Blenders who need a sealed outer envelope to protect tea from moisture and light
Brands requiring a professional appearance with a threaded tag and outer envelope
Producers who need to avoid direct contact with packaging materials during operation

Problems It Solves

Manual inner and outer bag assembly causes inconsistent sealing and increases contamination risk
Incorrect tag placement on hand-packed bags leads to poor brand image and customer complaints
Lack of barrier layers in single-layer packaging shortens shelf life for sensitive tea blends
Inconsistent fill volume from manual filling leads to overfilling or underfilling per bag
No integrated system for forming both inner and outer bags results in multiple machines and floor space

How It Compares

Manual inner and outer bag assembly	The C18 replaces hand packing with consistent, faster output and reduced contamination risk, but requires a fixed power and air supply
Single-layer filter paper bag machine	The C18 adds an outer envelope and barrier layers for better shelf life and brand protection, but uses more material and space
Flat bag machine with separate outer wrapping	The C18 integrates inner and outer bag formation into one process, reducing machine count and floor space, but requires more setup for multi-layer films

Use Guide

1Connect a single phase 220V 50Hz power supply and ensure stable voltage
2Load the selected inner and outer bag materials into the feeding system
3Set the inner bag size to 50-70 mm length and 40-80 mm width based on your product
4Set the outer bag size to 70-120 mm length and 60-90 mm width for your packaging format
5Adjust the volumetric cup to 3 to 15 ml fill volume and calibrate with your tea
6Enable photoelectric positioning for tag alignment and test a few bags before batch run
7Clean the filling cup and sealing area between product changes to avoid cross-contamination
