Product Overview
The Automatic Cardboard PE Bundling Machine is an end-of-line packaging machine designed for bundling stacks of corrugated cartons with PE strapping. It integrates automatic conveying, carton alignment, pressing, double-head PE strapping, and bundle output into one continuous process.
The machine is commonly installed after automatic folder gluers, folder gluer stitchers, or carton stitching machines to automate the final bundling process. It is suitable for corrugated carton manufacturers seeking stable bundle quality, reduced manual handling, and continuous production.
Key Features
PLC-Controlled Automatic Operation
The machine adopts a PLC control system for automatic operation. Carton size adjustment is simple, accurate, and suitable for production order changeovers.
Double-Head PE Strapping System
Two strapping heads tie PE straps simultaneously, improving bundling efficiency while providing secure and consistent bundle formation.
Automatic Conveyor System
The conveyor section automatically transports carton bundles from the previous production process to the bundling position.
Optional intermittent or continuous conveyor operation is available according to production requirements.
Servo-Driven Pusher Positioning
A servo-driven pusher transfers carton bundles accurately to the strapping position.
The pusher position is automatically adjusted through the touch screen according to carton dimensions.
Automatic Carton Alignment
The left and right alignment units automatically square the carton stack before bundling, helping improve bundle consistency.
The machine is suitable for cartons produced by folder gluers and carton stitchers.
Pneumatic Pressing Before Strapping
A pneumatic pressing device compresses the carton stack before bundling, helping maintain stable bundle shape during PE strapping.
PE Strapping
The machine uses PE strapping tape.
Compared with PP strapping, PE strapping provides lower consumable cost while meeting carton bundling requirements.
Flexible Production Integration
The machine can be connected with:
- Automatic folder gluer machines
- Automatic folder gluer stitchers
- Semi-automatic carton stitchers
- Other compatible carton finishing lines
Optional Functions
Optional configurations include:
- Side knot transfer system
- Dual electric pressing mechanism
- One-touch automatic size adjustment
- Telescopic delivery conveyor
- Powered or non-powered infeed conveyor

FAQ
1. What is an Automatic PE Bundling Machine used for?
An Automatic PE Bundling Machine is used to bundle stacks of corrugated cartons with PE strapping after the gluing or stitching process, preparing the finished cartons for storage or shipment.
2. Which machines can it be connected with?
It can be connected with automatic folder gluers, folder gluer stitchers, semi-automatic carton stitchers, and other compatible carton finishing equipment.
3. Why does the machine use PE strapping instead of PP strapping?
According to the machine design, PE strapping offers lower consumable cost than PP strapping while providing secure bundling for corrugated carton stacks.
4. How does the machine position carton bundles before strapping?
The machine uses a servo-driven pusher together with automatic alignment units to position and square the carton stack before the strapping operation.
5. Does the machine support different carton sizes?
Yes. The carton size can be adjusted through the control system, and optional one-touch automatic adjustment is available depending on the machine configuration.
6. Is the machine fully automatic?
Yes. After cartons enter the machine from the previous production line, conveying, positioning, alignment, pressing, PE strapping, and bundle output are completed automatically.
7. What optional configurations are available?
Optional configurations include a side knot transfer system, dual electric pressing mechanism, one-touch size adjustment, telescopic output conveyor, and different infeed conveyor types.
