C18 Full Automatic Inner and Outer Filter Paper Black Tea Machine

The C18 automatically forms, fills and seals inner and outer tea bags from a single roll of filter paper and composite material, running 40 to 60 bags per minute at 3 to 15 ml per bag. It is built for tea blenders and contract packers who need to package small granular tea blends in a two-layer structure with a thread and tag. The machine uses a volumetric cup filler and heat sealing, with photoelectric positioning for accurate tag placement and outer envelope formation.

Inner and outer bag formed simultaneously to reduce handling and contamination risk
Photoelectric positioning ensures consistent tag placement on every bag
Volumetric cup filling delivers repeatable 3 to 15 ml per bag with no manual adjustment
Adjustable inner and outer bag sizes to match different product formats and branding needs

Key Benefits

Inner and outer bag formed simultaneously to reduce handling and contamination risk
Photoelectric positioning ensures consistent tag placement on every bag
Volumetric cup filling delivers repeatable 3 to 15 ml per bag with no manual adjustment
Adjustable inner and outer bag sizes to match different product formats and branding needs
Thread and tag attachment is optional, allowing flexible configuration for different markets
Single operator can manage the line after setup, replacing manual packing teams

Application Scenarios

Tea blenders packaging black tea in a two-layer format for retail or gift sets
Contract packers producing multiple tea brands with different bag sizes and tag designs
Health tea producers needing a sealed inner bag with a branded outer envelope
Export-focused producers requiring consistent tag alignment for international retail standards

Who It Is For

Tea blenders moving from hand packing to in-house automatic inner and outer bagging
Contract packers serving multiple tea brands with varying bag sizes and tag styles
Producers who need a two-layer bag structure to protect tea from moisture and light
Buyers replacing a manual or semi-automatic system that cannot handle consistent tag alignment

Problems It Solves

Manual inner and outer bagging leads to inconsistent fill volume and tag misalignment
Single-layer bagging does not provide the moisture barrier or premium appearance of a double layer
Lack of photoelectric positioning causes tag placement errors across batches
Inconsistent inner bag size reduces product consistency and brand image
Hand threading and tagging slows output and increases labor cost

How It Compares

Single-layer filter paper tea bag machine	The C18 provides a sealed inner bag with a branded outer envelope, improving shelf life and premium appearance, but requires more setup time and material input
Manual inner and outer bagging	The C18 replaces a hand-filling team and ensures consistent fill and tag placement, but requires a fixed footprint of 1250 x 700 mm and trained operator
Flat bag machine with separate sealing	The C18 forms both bags at once and uses photoelectric positioning for tags, while flat bag machines require sequential steps and may miss alignment

Use Guide

1Connect a clean dry air supply at 0.6 MPa and a single phase 220V 50Hz outlet
2Load the filter paper roll for the inner bag and composite material for the outer envelope
3Set inner and outer bag dimensions to match your product size using the control panel
4Enter target fill volume between 3 and 15 ml and calibrate the volumetric cup with your tea
5Enable photoelectric positioning and test tag alignment with a sample run
6Run ten sample bags and check fill volume, seal integrity, and tag placement before batch start
