Tea is priced by weight. Weight accuracy, sealing quality and product changeover efficiency in the packaging process will affect raw material loss, shelf life and delivery schedule. When tea enterprises evaluate production line upgrading, full-automatic tea packaging machines, tea quantitative packaging machines and tea pre-made pouch packaging machines are often key items for comparison. Guangzhou Marchi Packaging Equipment Co., Ltd. has 27 years of industry experience in packaging equipment, and its MCGD8-200 solution offers targeted adaptation ideas for tea packaging scenarios.
I. Common Concerns of Tea Enterprises in Packaging Processes
Weight fluctuation. Strip-shaped tea, granular tea and tea powder differ in fluidity and bulk density. Semi-automatic weighing is easily affected by ambient temperature, humidity and material conditions. Accumulated deviations of individual bags will lead to a notable rise in raw material costs.
Sealing performance. Tea is sensitive to oxygen and moisture. Improper coordination of heat sealing temperature, pressure and time may result in weak seals, film scorching or micro-leakage. Tea dust residue at the pouch opening can also compromise sealing integrity.
Changeover and commissioning. Tea manufacturers often produce pouches of various specifications including stand-up pouches, zipper pouches, flat pouches and spout stand-up pouches. Traditional machine adjustment requires tuning each set of grippers separately, leading to long changeover time and disruption to continuous production.
II. Marchi MCGD8-200 Tea Pre-Made Pouch Packaging Machine Solution
Guangzhou Marchi Packaging Equipment Co., Ltd. has long focused on the R&D and manufacturing of packaging equipment. The MCGD8-200 is a tea pre-made pouch packaging machine and can also be used for quantitative tea packaging. This model is suitable for medium and large-batch continuous production, and is worth attention for tea factories handling a wide range of pouch sizes.
Model selection. The MCGD8-200 supports packaging dimensions of 100 to 300 mm in length and 100 to 200 mm in width, covering most retail tea pouch specifications. Applicable pouch types include stand-up pouches, zipper pouches, spout stand-up pouches and flat pouches.
Core configuration. The machine adopts PLC control and human-machine interface. Operators set parameters and monitor operation via the touch screen. Pouch width adjustment is motor-driven, and all groups of grippers can be synchronously adjusted with one button. Parts in contact with materials are made of 304 or 316 stainless steel or food-grade plastic to meet hygiene requirements. The machine is equipped with interlock logic: no feeding if there is no pouch or the pouch is incompletely opened; no material discharge without successful pouch opening; no sealing without pouch or feeding. Machine stop and alarm functions for door opening, missing colour band, insufficient air pressure and abnormal sealing temperature are optional.
Key parameters. Model: MCGD8-200; packaging speed: 25 to 90 pouches per minute; applicable materials: composite films such as PE composite film, aluminium foil film and aluminized film; automatic pouch width adjustment. Aluminium foil film and aluminized film feature good barrier properties against moisture and oxygen. Combined with stable heat sealing control, they help extend the shelf life of tea.
III. Packaging Process: From Pouch Feeding to Palletizing
The operating sequence of the MCGD8-200 is: pouch feeding — coding — zipper opening — pouch opening — metering and feeding — cleaning — heat sealing — shaping. The pouch feeding mechanism picks pouches from the magazine and transfers them to rotating stations. The coding station prints production dates or batch numbers. The zipper opening and pouch opening stations stretch open the pouch mouth. The metering and feeding station fills tea according to the set weight. The cleaning station blows the inner side of the pouch mouth to reduce tea dust residue. The heat sealing station seals the pouch opening. The shaping station flattens and regularizes the pouch body.
Shaped finished pouches are conveyed to downstream processes by the output conveyor. Depending on production line configuration, they can be connected to weight checking, metal detection, automatic case erecting, case packing, case sealing and other procedures. A robotic palletizing station stacks cartons according to preset pallet patterns. Finished cartons are transported to the warehouse by forklifts or AGVs. The whole workflow extends from single pouch packaging to finished palletizing, reducing manual handling and repetitive operations.
IV. Range of Applicable Materials
This solution covers green tea, Longjing tea, Biluochun tea, Huangshan Maofeng tea, black tea, Lapsang Souchong, Jinjunmei, Keemun black tea, oolong tea, Tieguanyin, Da Hong Pao, Fenghuang Dancong, white tea, Baihao Yinzhen, White Peony, dark tea, loose Pu’er tea, jasmine tea, chrysanthemum tea, tea dust, tea powder, herbal granules and other materials. For tea enterprises with multi-category production, one machine compatible with multiple tea types helps improve equipment utilization rate.
V. Customer Pain Points and Solutions
Weight fluctuation: The metering and feeding system cooperates with PLC control to adjust feeding parameters according to material fluidity. For mixed packaging of strip-shaped and granular tea, low-speed stirring or intermittent feeding can be adopted at the feeding end to reduce material segregation.
Sealing leakage: The cleaning station blows the pouch mouth to lower the risk of tea dust residue. Heat sealing parameters remain stable, and the abnormal sealing temperature alarm prompts operators to take timely action.
Changeover efficiency: One-button synchronous pouch width adjustment replaces separate tuning of each gripper group, shortening pouch type switching time.
Production line connection: Continuous configuration from the main packaging machine to case packing and palletizing enables finished products to enter warehousing without manual transfer and reduces intermediate stagnation.
For tea enterprises researching full-automatic tea packaging machines, tea quantitative packaging machines and tea pre-made pouch packaging machines, the MCGD8-200 solution from Guangzhou Marchi Packaging Equipment Co., Ltd. can serve as a reference for model selection. Specific configurations and production line plans can be further customized according to material characteristics and factory conditions.
