With the continuous expansion of the tea consumption market, categories including green tea, black tea, oolong tea, white tea, dark tea, scented tea, fruit tea, tea bags and health-care tea have been enriched constantly, and tea enterprises have increasingly prominent demands for automation in packaging processes. Traditional manual weighing and sealing methods have limitations in efficiency, precision and hygiene control, so vertical tea packaging machines have gradually become an important option for tea enterprises to upgrade production lines. With 27 years of experience in packaging machinery, Guangzhou Marchi Packaging Equipment Co., Ltd. takes the MC5000D vertical automatic packaging machine as the core to provide tea enterprises with automatic packaging solutions ranging from single machines to complete production lines.

I. Integration Characteristics of Vertical Granule Packaging Machine Unit
The MC5000D vertical granule packaging machine consists of one 5000D vertical filling packaging machine, linear weigher and bucket elevator. It integrates weighing, bag forming, filling, sealing, coding, hole punching and counting. A three-servo system is adopted for film pulling and sealing to ensure stable and reliable equipment operation. Control components adopt mature brands with reliable performance. Reasonable design concept enables the unit to run stably with simple operation and convenient maintenance.
Equipment parameters: Model MC5000D; bag size range L×W: (50～280) × (70～200) mm; applicable bag types include pillow bag, stand-up bottom bag, punched bag, hand-held bag, box-type bag, etc.; weighing range: 10～500g; weighing accuracy: ±0.2%～0.5%; packaging speed: 25～80 bags per minute. The unit is suitable for tea materials such as black tea, green tea, oolong tea, white tea, Pu'er tea, Tieguanyin, Longjing, Biluochun, jasmine tea, Da Hong Pao, chrysanthemum tea, cassia seed tea, health-care tea and fruit tea. It is also compatible with granular materials such as coffee beans, nuts, melon seeds, seeds, white granulated sugar, edible salt, oatmeal and desiccants.
II. Packaging Process of Vertical Automatic Tea Packaging Machine
During production line operation, the packaging process of vertical automatic tea packaging machine covers multiple links. Operators feed tea to be packaged into the hopper. The bucket elevator conveys materials at a constant speed to the linear weigher for dynamic weighing, and weighing data is fed back to the control system in real time to complete metering. Afterwards, the vertical filling packaging machine completes roll film bag forming, material filling and dropping, longitudinal sealing and transverse sealing, coding, hole punching, counting and other procedures. The three-servo system drives film pulling and sealing to achieve neat bag forming.
Finished bags are transported by conveyor belt to weight inspection and metal detection links to eliminate unqualified products. Then the automatic case erector opens cartons, the case packer loads finished bags into cartons according to the set quantity, the case sealing and strapping integrated machine completes carton sealing and strapping, and finally the robotic palletiser stacks finished cartons neatly according to the preset pallet pattern. Cartons are delivered to the warehouse area by pallet conveyor. The whole process can be summarised as: feeding → lifting → linear weigher metering → vertical bag forming, filling and sealing → weight inspection and metal detection → case erection → case packing → case sealing and strapping → robotic palletising → warehousing, realising continuous operation from bulk tea to finished pallets.
III. Model Selection and Core Configuration
When selecting models, tea enterprises can comprehensively consider material characteristics, bag specifications, capacity requirements and workshop layout. The MC5000D vertical automatic packaging machine is suitable for tea and granular materials within the weighing range of 10～500g, supports multiple bag types with packaging speed of 25～80 bags per minute. Specifications of linear weigher and elevator can be matched according to actual output. In terms of core configuration, the unit adopts three-servo system to control film pulling and sealing, equipped with linear weigher for dynamic weighing, bucket elevator for material conveying, and mature brands for control components to facilitate daily maintenance and spare parts replacement.
IV. Customer Pain Points and Marchi Solutions
Pain Point 1: Tea is fragile and broken tea dust is generated during material dropping. Marchi optimises the buffer structure in the blanking channel to support materials during falling, helping reduce the proportion of broken tea and keep the integrity of tea strips.
Pain Point 2: Fluctuation of metering accuracy and unstable weight of single bag. Tea varies greatly in density, and strip tea and granular tea differ in flowability. Marchi adopts high-precision linear weigher combined with dynamic weighing technology, with stable metering accuracy of ±0.2%～0.5%. Blanking parameters can be adjusted for different tea types to ensure consistent weight of each bag.
Pain Point 3: Cumbersome switching among multiple varieties and long product changeover time. MC5000D supports various bag types including pillow bag, stand-up bottom bag, punched bag, hand-held bag and box-type bag. Bag length and weighing range can be adjusted within the set interval. Operation is simple when replacing packaging specifications, helping shorten production line switching time.
Pain Point 4: Frequent manual contact and high pressure on hygiene control. From weighing and sealing to case packing and palletising, the MC5000D unit realises full-process automatic operation, reducing links of direct manual contact with materials and packages, helping tea enterprises improve the standardisation level of production process.
Guangzhou Marchi Packaging Equipment Co., Ltd. is headquartered in Panyu District, Guangzhou. It owns two production bases in Guangzhou and Hefei with a total of more than 9,500 square metres of standard production workshops, building a two-way production and service system covering South China and East China.

Cooperative customers cover food & beverage, pharmaceutical health and other fields. Whole-plant solution design and non-standard customization are supported, as well as material test runs and factory visits.
For tea enterprises, selecting a vertical tea packaging machine adapted to their own material characteristics is not only related to the gram weight accuracy and appearance quality of single-bag products, but also affects the operation efficiency and labour cost of the whole production line. Featuring stable metering performance, flexible bag adaptability and complete production line connection solutions, Marchi MC5000D vertical automatic packaging machine provides a practical path for tea enterprises ranging from single machine to complete production lines.
