Filter Tea Bag with Envelope Packing Machine
Automated inner filter paper bag forming, volumetric tea dosing, cotton thread & paper tag attachment, and protective outer envelope sealing engineered by Spartan Machine Co., Ltd.
Precision Tea Packaging for Commercial Production Lines
Designed specifically for global tea processors, co-packers, and commercial brand owners who require consistent dosing, reliable thread knotting, and hermetic outer pouch sealing.
Engineered to Eliminate Bottlenecks in Fine-Cut & Herbal Tea Lines
The SPM-T100 industrial platform provides complete automation from raw tea dosing to finished individual envelope discharge. By pairing heat-sealable filter paper forming with an integrated mechanical thread dispenser and outer envelope wrapper, Spartan Machine Co., Ltd. ensures high productivity while preserving delicate tea aroma.
Compatible Leaf & Granule Categories:
- CTC & Fine-Cut Black Tea: Consistent filling with adjustable volumetric cups.
- Broken Green Tea & Oolong: Minimal leaf degradation during feeding cycles.
- Herbal Blends & Infusions: Handles mixed piece sizes without component segregation.
- Dried Fruit & Flower Pieces: Configurable feed routes to prevent material bridging.

Integrated Process Sequence & Station Details
Every station is precision-machined to ensure continuous alignment, clean heat seals, and zero thread tangling during high-speed runs.
Precision Volumetric Dosing
Features adjustable volumetric cups made from food-grade 304/316 stainless steel. Eliminates product degradation while ensuring volumetric dose variance remains strictly within target ranges.
Filter Paper Forming & Sealing
Custom-milled heat-sealing jaws create robust vertical and bottom seals on heat-seal filter paper. Constant temperature controllers maintain precise thermal output for leak-free inner bags.
Automated Thread & Tag Feeding
Mechanical knotting or heat-tack dispenser feeds food-grade cotton string and paper tags directly into the inner bag seal structure without adhesive contamination.
Envelope Transfer & Insertion
High-accuracy mechanical arm transfers the finished inner filter tea bag into the outer envelope forming collar without tearing the filter paper or catching the tag string.
Hermetic Outer Envelope Sealing
Supports 3-side seal or pillow envelope styles. Photo-eye registration system aligns pre-printed rollstock graphics accurately for clean brand representation on shelf.
Discharge & Batch Coding
Integrated date/lot coding system (ribbon or ink-jet) imprints clear batch numbers on the outer envelope prior to discharge onto optional collection conveyors.
Quality Assurance & Post-Sale Commitment
Purchasing machinery overseas demands strict quality control, verified electrical compliance, and responsive technical support.
Factory Acceptance Testing (FAT) & Sample Testing
Prior to shipping, Spartan Machine Co., Ltd. conducts comprehensive FAT protocols. We invite overseas buyers to submit representative tea samples and envelope film. Our engineers run dry-cycle and actual-fill tests, providing full video proof and dimensional verification before your equipment leaves our floor.
- Compliance Standards: Built in accordance with international CE standards and food safety hygiene practices.
- 12-Month Warranty: Complete technical coverage extending 12 months from machine arrival at your facility.
- Remote Technical Support: Video diagnostics, electrical schematics, and operator video guides ensure fast troubleshooting.
- Spare Parts Supply: Critical wear parts (heating elements, cutting knives, thermocouple sensors) included with shipment.

Spartan Machine Co., Ltd. itemizes every quotation transparently. We explicitly list machine components, PLC controller brands, spare part packages, and site utility requirements so your engineering team experiences zero budget surprises during commissioning.
Frequently Asked Questions by Overseas Buyers
Direct, unvarnished answers regarding machine capabilities, material choices, and commissioning.
Can this machine run my tea blend in my specific outer envelope material?
Product behavior and film structure determine compatibility. Cut teas, fine CTC, and uniform herbal blends run reliably on volumetric cup feeders. Filter paper must be heat-sealable grade (16.5–21 gsm), while outer envelope film can be paper/PE, foil laminates, or plastic structures.
Spartan Machine Co., Ltd. verifies your tea flow characteristics and film sealing temperature using physical sample testing before finalizing machine tooling specifications.
Is thread and tag attachment mandatory on the SPM-T100 series?
No. While the SPM-T100 includes automatic thread dispenser and tag feeder assemblies as standard, the system can be configured or disengaged to produce plain filter bags without string/tag inside an outer envelope if required by your product line.
What is excluded from a standard equipment quotation?
Common exclusions include external factory utility lines (main power drops, compressed air piping), secondary cartoning/case packing lines beyond the discharge chute, raw packaging consumables (filter paper rolls, thread, tags, envelope film), and civil site modifications.
All itemized quotes from Spartan Machine Co., Ltd. outline explicitly what is included, what is optional, and what must be supplied by the customer site.
How is overseas operator training and post-warranty service handled?
Machines are fully assembled and pre-tested prior to dispatch. Upon arrival, training is conducted remotely via comprehensive video guides, step-by-step documentation, and live video sessions with our engineering staff.
Should on-site technician commissioning be requested, Spartan Machine Co., Ltd. dispatches field engineers under mutually agreed terms covering daily service fees, travel, and accommodation.
