Automatic Inner and Outer Tea Bag Packing Machine with Envelope

Why Do Premium Tea Brands Use Inner and Outer Tea bags? 

Filter paper alone cannot protect tea aroma. Moisture and air quickly degrade the quality of tea in simple filter bags. The LTC Inner & Outer Machine solves this by adding a secondary layer of protection. It packs the filter bag into a Plastic or Paper/PE Outer Envelope, sealing in the freshness and aroma for a longer shelf life.

Features

• Dual Bagging: Forms the inner filter bag and outer wrapper in one continuous process.

• Tag & Thread: Automatically attaches the thread and tag to the inner bag (using mechanical knotting or heat seal).

• Versatile Outer Bag: Can use heat-sealable foil, paper/PE, or plastic laminates for the outer envelope.

• High Efficiency: One operator can manage multiple machines, significantly reducing labor costs.

Ideal Applications

Designed for fine tea granules and powders:

• CTC Black Tea (Lipton Style)

• Broken Green Tea

• Herbal Medicine Tea / Slimming Tea

• Tieguanyin (Fine grade)
