The MR8-R series is engineered for automatic metering, filling and sealing of large-format premade bags. Three frame sizes cover bag widths from 100 to 400 mm, providing a flexible solution for granules, powders, liquids and sauces.
The MR8-R Series Large-Format Premade Bag Feeding Packing Machine is an advanced automatic packaging solution developed by Wenzhou Echo Intelligent Packaging Technology Co., Ltd. for large-size premade pouch applications. Designed for industries including food, beverage, chemical, and healthcare packaging, this series provides a flexible and efficient solution for automatic bag feeding, opening, filling, sealing, and discharge of various products.
The MR8-R series includes three models: MR8-200R, MR8-300R, and MR8-400R, covering different bag width ranges from 100 mm to 400 mm. With optimized mechanical structures and intelligent control systems, the machine can handle different product types, including granules, powders, liquids, sauces, and other packaged materials requiring large-format bags.
Based on 26 years of packaging machinery manufacturing experience, Wenzhou Echo Intelligent Packaging Technology Co., Ltd. provides complete automated packaging solutions for global customers. As a professional packaging machine manufacturer and national standard contributor for automatic premade pouch packaging equipment, ECHO Machinery integrates precision engineering, advanced automation technology, and strict quality control to deliver reliable packaging systems for international markets.
The MR8-R series is designed for manufacturers requiring high-efficiency packaging in larger premade bags. It is suitable for various industries where stable filling accuracy, reliable sealing performance, and flexible bag compatibility are required.
Typical applications include:
The machine supports multiple types of premade bags, including stand-up pouches, handbag-style bags, zipper bags, four-side sealed bags, three-side sealed bags, paper bags, and other composite packaging bags.
The MR8-R series adopts an advanced bag-feeding mechanism designed for accurate and stable pouch handling. The automatic feeding system reduces manual intervention, improves packaging consistency, and ensures smooth operation during continuous production.
The optimized structure allows the machine to handle different bag sizes and materials while maintaining reliable positioning accuracy throughout the packaging process.
The machine features a robust mechanical transmission system combined with high-performance heat sealing technology. The stable operating structure ensures consistent sealing quality, helping prevent leakage and improving the appearance and reliability of finished packages.
ECHO Machinery applies precision manufacturing technology and carefully selected components to improve machine durability and extend service life under demanding production conditions.
Equipped with a PLC control system and user-friendly touch panel interface, the MR8-R series enables convenient operation, parameter adjustment, and production monitoring.
Operators can easily manage packaging settings, adjust filling parameters, and monitor machine status through the intelligent control interface, reducing operation complexity and improving production efficiency.
One of the key advantages of the MR8-R series is its wide compatibility with different large-format premade bags. The three machine models provide different working ranges:
This flexible configuration allows customers to select the most suitable machine according to their packaging size requirements.
The machine is designed with precise bag handling technology to minimize empty bag waste and improve material utilization. It can also be integrated with different upstream and downstream equipment, creating a complete automated packaging production line.
Optional equipment can include filling systems, printing systems, conveyors, inspection equipment, and other customized modules according to production requirements.
The MR8-R series completes the packaging process automatically through the following steps:
Bag Picking → Optional Printing → Bag Opening → Filling 1 → Filling 2 → Heat Sealing 1 → Heat Sealing 2 → Forming and Discharge
The multi-stage filling and sealing process provides improved packaging accuracy and sealing performance, especially for products requiring larger filling volumes or multiple filling operations.
