Pre-opened Bag Making Machines

Model 550 Packing Machine with computer and printer

The Model 550 Packing Machine converts pre-opened PE bags on a roll into sealed, labelled bags at speeds up to 1800 bags per hour. It is designed for use in automated bagging lines where consistent, high-speed packaging is needed. The machine integrates a touch screen control system, label printer, and air pump to handle bag width from 200 mm to 550 mm and length from 250 mm to 800 mm. It supports continuous operation with minimal operator intervention.

  • Automates bag sealing and labelling with a single operator, reducing labour costs
  • Operates at up to 1800 bags per hour, matching high-volume e-commerce and fulfilment demands
  • Touch screen interface allows quick setup and real-time monitoring of production
  • Integrated label printer supports variable label sizes up to 100 mm wide with no length limit
  • Static elimination system prevents material jams and ensures smooth operation
  • Compact footprint and low air consumption (0.05 m³/min) reduce site infrastructure needs
Problems It Solves

Why Buyers Choose It

  • Manual bagging is slow and inconsistent, leading to labour bottlenecks during peak periods
  • Lack of labelling capability on pre-opened bags makes traceability difficult for compliance
  • Static electricity causes bags to stick together or misfeed, disrupting the line
  • Existing bagging lines lack integration between sealing and labelling steps
  • Operators must be trained repeatedly due to complex or non-intuitive machine controls
Who It Is For

Who Runs This Machine

Process

How The Machine Runs

Step 1Load a roll of pre-opened PE bags onto the machine’s unwind stand
Step 2Set bag length, label position, and speed via the touch screen interface
Step 3Start the machine and allow the air pump to build pressure
Step 4Feed the bag through the double-track membrane conveyor to the sealing and cutting station
Step 5Apply label at the designated position using the integrated printer

Materials

  • Pre-opened PE bags on a roll
  • Label stock compatible with the integrated printer
  • Air supply for pneumatic components (0.05 m³/min required)

Quality Control

  • Static elimination system ensures consistent bag feeding and prevents jams
  • Double-track membrane conveyor maintains alignment and reduces wear
  • Sealing temperature and pressure are stable across runs to prevent leaks
  • Label printer is tested with sample stock before shipment to verify print clarity
  • Machine is run with customer-provided bags during final testing

Customisation

  • Label printer can be configured for different label formats and print speeds
  • Conveyor height and output angle adjusted for integration with downstream systems
  • Control panel language can be set to match operator preference
  • Optional safety enclosures or guards added for high-risk environments
  • Power supply can be adapted to local voltage and frequency if required

Certifications

  • ISO9001:2000 certificate obtained in 2005
  • CE certificate obtained in 2006
Comparison

How It Compares

Manual bagging with hand sealersThe Model 550 increases output from 100-200 bags/hour to 1800 bags/hour with one operator
Basic automatic baggers without printersThis model includes integrated labelling, which reduces the need for a separate printer station
Larger industrial autobaggersThe Model 550 has a smaller footprint and lower power requirement, suitable for smaller facilities
Use Guide

Running It On Your Floor

  1. Ensure the air pump is connected and pressurized before starting the machine
  2. Load the pre-opened PE bag roll onto the unwind stand and align the web
  3. Set the desired bag length and label position on the touch screen
  4. Run a test cycle with a few bags to verify sealing, cutting, and label placement
  5. Adjust the sealing temperature or pressure if the seal is weak or the bag tears
  6. Keep the label printer head clean and replace labels when the roll is empty
