C18-2 Heat Sealing Herbal Tea Bag Filter Paper Machine (Upgrade Version)

The C18-2 forms and fills inner and outer tea bags simultaneously from filter paper and composite materials, running 40 to 60 bags per minute at 3 to 15 ml per bag. It is designed for tea blenders and health-tea producers who need to pack small granular blends with a visible inner bag and a branded outer envelope. The machine uses a measuring cup filler and heat sealing to close both bags in one cycle, with optional thread and tag attachment and photoelectric positioning for accurate tag placement.

Forms inner and outer tea bags at the same time, reducing manual handling and improving hygiene
Heat sealing ensures a tight closure without adhesive, suitable for dry granular products
Photoelectric positioning allows accurate tag placement on the outer bag for consistent branding
Adjustable inner and outer bag sizes to match different product formats and packaging designs

How It Compares

Manual inner and outer bag formation	The C18-2 automates both bag formation and sealing, reducing labor and improving consistency, but requires a fixed power and air supply
Flat bag machine with separate sealing	The C18-2 forms both bags in one cycle, reducing handling, but uses heat sealing which may not suit heat-sensitive materials
Machine without photoelectric positioning	The C18-2 ensures accurate tag placement, but requires a tag with a detectable edge for the sensor

Use Guide

1Connect a clean dry power supply at 220V 50Hz and ensure the 3.7 kW motor is supported
2Load the inner filter paper and outer composite film rolls according to the bag size settings
3Set the measuring cup to 3 to 15 ml based on the product density and desired fill
4Adjust inner and outer bag dimensions to match the required bag format
5Enable photoelectric positioning and test tag placement with a sample run
6Run ten test bags and verify fill volume, seal integrity, and tag alignment before full batch
