Machine Features：

The inner and outer bag tea packaging machine (also often called a "bag-in-bag" or "integrated inner and outer bag machine") is a highly efficient, fully automatic tea packaging equipment, mainly suitable for quantitative packaging of granular or small powdery teas such as green tea, black tea, herbal tea, and health tea. Its core features are mainly reflected in the following aspects:

①Fully automated process, high efficiency and labor saving

The machine can automatically complete all packaging processes from inner bag to outer bag in one go, including material weighing, inner bag making and filling, sealing and cutting, outer bag forming, filling the inner bag into the outer bag, sealing the outer bag, and finished product output. This highly integrated design avoids direct contact between human hands and materials, which not only greatly improves production efficiency (generally reaching speeds of 30-50 bags per minute), but also significantly reduces the company's labor costs.

②Unique "thread and label" function, enhancing product quality

This is a major highlight of this type of equipment. It can automatically attach cotton thread and labels when making the inner bag.

Good user experience: The cotton thread makes it convenient for consumers to hang and remove the tea bags when brewing.

Excellent Brand Promotion:Labels can be printed with the brand logo, tea name, or brewing instructions, effectively enhancing the product's visual appeal and brand recognition.

③Double Sealing Protection, Locking in Freshness and Preventing Moisture

Utilizing a double packaging design of "inner bag + outer bag":

Inner Bag: Typically made of food-grade filter paper, non-woven fabric, or nylon, formed using ultrasonic welding or heat sealing technology to ensure the safety of the tea during brewing and maintain effective water filtration.

Outer Bag: Often made of composite film (such as PET/AL/PE) or composite paper, possessing excellent moisture-proof, oxidation-proof, and odor-blocking properties. This effectively locks in the aroma and freshness of the tea, significantly extending the product's shelf life.

④Intelligent and Precise Control, Stable and Hygienic Operation

Modern models generally employ an industrial-grade PLC control system paired with a touchscreen human-machine interface, offering simple operation and flexible parameter adjustment.

High-precision weighing: Equipped with an electronic scale or screw metering device, it ensures minimal weight error for each bag of tea (some high-precision models can control the error to ±0.1g to ±0.2g), reducing material waste.

Hygienic and reliable: All parts in direct contact with the material are typically made of SUS304 stainless steel, meeting food hygiene and safety standards. In addition, the equipment supports additional functions such as printing production dates on the outer bag and cutting easy-tear openings.

Machine Details：

Machine commonly consists of scale weighing system and the ultrasonic pyramid bagging machine.

①Customized scale system (2/4/6/8 head) is available for mixed tea types package or per packaging weight to achieve high filling accuracy of +/-1%.

②ultrasonic pyramid bagging machine automatically completes the entire process of tea metering and filling, pyramid or flat bag making, sealing, and cutting.

Technical Advantages：

Specialized Design for Dual-layer Tea Bag

Tailor-made structure adapts perfectly to inner filter bag and outer packaging bag integrated packaging. It realizes orderly bag making, filling and sealing without bag dislocation or damage, keeping finished tea bags neat and standard.

Accurate Quantitative Feeding System

Equipped with high-precision metering device, it stably controls tea leaf weight. Consistent filling volume ensures uniform product specification, meeting commercial graded tea packaging standards.

Multi-layer Tight Sealing Technology

Adopts constant temperature heat sealing structure. Sealing edges are firm and smooth, featuring excellent moisture-proof, dust-proof and fragrance-locking effect. Effectively prevent tea leaves from damp deterioration and aroma loss.

Low-break Gentle Material Handling

Buffering feeding mode avoids tea leaf crushing and fragment generation. Well preserve complete tea shape and original natural taste of tea products.
