This series combines automatic premade-pouch filling with vacuum extraction, optional nitrogen flushing and heat sealing. Dual rotating systems separate filling and vacuum operations for continuous and reliable production.
The MRZK Series Vacuum & Nitrogen-Flushing Premade Pouch Packing Machine is an advanced automatic packaging solution developed by Wenzhou Echo Intelligent Packaging Technology Co., Ltd. for products requiring vacuum protection, nitrogen flushing, and high-quality sealing performance. Designed for food, agricultural products, medicines, hardware, electronics, and other industries, this series integrates automatic pouch handling, product filling, vacuum extraction, optional nitrogen flushing, heat sealing, and finished product discharge into one complete packaging system.
The series includes three models: MRZK12-161, MRZK12-162, and MRZK10-241, providing flexible solutions for different pouch sizes and production requirements. With dual rotating systems that separate filling operations from vacuum processing, the machine achieves continuous operation, improved packaging efficiency, and stable sealing performance.
By combining vacuum technology and optional nitrogen flushing, the MRZK series helps reduce oxygen exposure inside the package, protect product quality, and extend storage stability. It is an ideal solution for manufacturers requiring reliable protective packaging with attractive appearance and consistent performance.
With 26 years of experience in packaging machinery manufacturing, Wenzhou Echo Intelligent Packaging Technology Co., Ltd. specializes in automatic packaging equipment and complete packaging line solutions. ECHO Machinery integrates precision engineering, intelligent control systems, and customized service capabilities to support global customers across food, medical, industrial, and consumer product industries.
The MRZK vacuum and nitrogen-flushing pouch packaging machine is suitable for products requiring enhanced protection against oxygen, moisture, and environmental factors.
Typical applications include:
Compatible packaging materials include:
The flexible machine configuration allows customers to select suitable models according to product characteristics, pouch dimensions, and production capacity requirements.
The MRZK series combines vacuum extraction technology with optional nitrogen flushing to create a controlled packaging environment.
During the packaging process, air inside the pouch can be removed and replaced with nitrogen according to product requirements. This helps minimize oxidation, maintain product freshness, and improve storage performance.
The technology is especially suitable for products sensitive to oxygen exposure or requiring extended shelf life.
The machine adopts a dual rotating structure that separates filling operations from vacuum and sealing processes.
This optimized design provides:
The separated working stations help maintain reliable performance during long-term production.
The MRZK series features an automatic bag-width adjustment system that improves machine adaptability when handling different pouch specifications.
This reduces manual adjustment requirements and helps simplify production changeovers.
Product-contact components are manufactured from 304 stainless steel, meeting hygienic requirements for food and sensitive product packaging applications.
The corrosion-resistant structure provides:
The machine is equipped with a Siemens PLC control system and intuitive touch-screen interface for convenient operation.
Operators can easily monitor production status, adjust packaging parameters, and manage machine functions through the centralized control system.
The intelligent control platform improves operating efficiency and supports stable automated production.
The machine is designed with an intelligent protection function:
This function helps reduce packaging material waste, improve production efficiency, and maintain consistent packaging quality.
The MRZK series uses an instant heating sealing system combined with water cooling technology.
This design provides:
The optimized sealing process ensures reliable package integrity for different composite pouch materials.
The MRZK series completes the packaging workflow through the following steps:
Pouch Picking → Optional Printing → Pouch Opening → Filling → Secondary Filling → Transfer → Vacuum / Nitrogen Flushing → Heat Sealing and Discharge
The multi-stage process ensures accurate filling, effective air removal or nitrogen replacement, reliable sealing, and consistent finished package quality.
