C18 Heat Sealing Black Tea Bag Packing Machine

The C18 automatically forms, fills and heat seals inner and outer tea bags from a single roll of 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 consistent, branded packaging for black tea, medicinal tea and health tea with a visible tag and thread. The machine forms both inner and outer bags simultaneously, reducing manual handling and improving hygiene. Photoelectric positioning ensures accurate tag placement on the outer envelope.

Forms inner and outer tea bags at the same time, reducing operator contact with packing materials
Photoelectric positioning ensures precise tag and thread placement on the outer bag
Adjustable inner and outer bag sizes allow for multiple product formats on one machine
Measuring cup filling delivers consistent volume across batches without weight variation
