C18 Automatic Filter Paper Black Tea Bag Packaging Machine

The C18 automatically forms, fills and seals inner and outer tea bags from filter paper and composite film, 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 replace manual packing or outsourced bagging with a single machine that handles both inner and outer bag assembly. The machine uses a volumetric cup filler and photoelectric positioning for tag and outer envelope alignment, reducing handling and improving consistency.

Forms inner and outer tea bags simultaneously, reducing operator contact with packaging materials
Photoelectric positioning ensures accurate tag and outer envelope placement on every bag
Volumetric cup filling delivers consistent 3 to 15 ml per bag with no manual adjustment needed
Inner and outer bag sizes can be adjusted quickly to match different product formats

Key Benefits

Forms inner and outer tea bags simultaneously, reducing operator contact with packaging materials
Photoelectric positioning ensures accurate tag and outer envelope placement on every bag
Volumetric cup filling delivers consistent 3 to 15 ml per bag with no manual adjustment needed
Inner and outer bag sizes can be adjusted quickly to match different product formats
Optional thread and tag attachment improves brand presentation and consumer usability
Single machine handles both inner and outer bag production, reducing line footprint

Application Scenarios

Tea blenders producing small batches of black tea with branded tags and outer envelopes
Contract packers handling multiple tea brands with different bag sizes and tag positions
Health tea producers packaging medicinal blends in sealed, tamper-evident outer bags
Export-focused factories needing consistent packaging for international retail channels

Who It Is For

Tea blenders moving from hand packing to in-house automatic bagging
Contract packers serving multiple tea brands with different inner and outer bag formats
Producers who need branded tags and outer envelopes on every tea bag

Problems It Solves

Manual inner and outer bag assembly causes inconsistent fill and misaligned tags
Separate machines for inner and outer bags increase floor space and operator workload
Poor tag alignment reduces brand image and consumer trust in premium tea
Lack of photoelectric control leads to mispositioned outer envelopes and rejected bags
Inconsistent fill volume across batches affects customer satisfaction and compliance

How It Compares

Separate inner and outer bag machines	The C18 combines both steps into one line, reducing floor space and operator handling, but requires a single machine with dual material input
Manual inner and outer bag assembly	The C18 eliminates hand labor and ensures consistent fill and tag alignment, but needs a fixed 1250 x 700 mm footprint and trained operator
Machine without photoelectric positioning	The C18 ensures precise tag and envelope placement, but requires clean photoelectric sensors and stable lighting

Use Guide

1Connect a clean dry air supply at 0.6 MPa and a single phase 220V 50Hz outlet
2Load the inner filter paper and outer composite film rolls according to the bag size
3Set inner and outer bag dimensions using the machine's adjustment controls
4Adjust tag size and position using the photoelectric sensor settings
5Set the volumetric cup to 3 to 15 ml and calibrate with your own tea
6Run ten test bags and check fill volume, tag position, and seal integrity before batch start
7Clean the filling cup and sealing heads between different tea types to avoid cross-contamination
