Bag-in-Bag Packaging Machine

The Bag-in-Bag Packaging Machine is designed for secondary packaging of small pre-packed items into larger outer bags. It efficiently handles multiple small inner pouches — such as sauces, condiments, candies, or powders — and automatically sorts and packs them into one unified outer bag.
Integrated with automatic feeding and sorting systems, it provides a fully automated packaging solution for multi-pouch or irregularly arranged inner packs, significantly improving efficiency and reducing labor intensity.

This model supports flat pouches, stand-up pouches, and stand-up zipper bags, offering flexible adaptation for various product types and packaging requirements.

Key Features

  • Hygienic and Durable Construction:
    The machine body is made of stainless steel, with product-contact parts built from SUS403 / 316L stainless steel or other food-grade materials, ensuring high hygiene standards and corrosion resistance.

  • Smart Control System:
    Uses an advanced PLC and touch screen interface for easy operation and real-time monitoring; can be connected to the MES system for production data management.

  • Precise and Efficient Packaging:
    Automatically controls feeding and sealing synchronization to ensure no material waste. Equipped with an empty bag detection system that prevents sealing of unfilled bags, reducing packaging waste.

  • Perfect Sealing Finish:
    The sealing station is specially designed for flat and wrinkle-free seals, ensuring excellent packaging appearance and low defect rates.

  • Easy Maintenance:
    Mechanical drive system with self-lubricating bearings reduces lubrication points, simplifies maintenance, and extends equipment life.

  • Flexible Integration:
    Compatible with a variety of upstream feeding systems, weighing equipment, and automatic sorting solutions.
