The Box Pre-Stretch Wrapper Machine is an industrial packaging machine designed to securely wrap cartons and boxes using pre-stretched stretch film. By pre-stretching the film before application, the machine provides uniform tension, better load stability, and reduced film usage, ensuring efficient, damage-free packaging.
Step-by-Step Operation:
Load Boxes: Place cartons or boxes evenly on a pallet or conveyor.
Install Film Roll: Mount the pre-stretch film on the carriage system.
Set Wrapping Parameters: Choose wrapping cycles, speed, and number of layers.
Start the Wrapping Cycle: The film carriage applies pre-stretched film while moving vertically (up and down) around the boxes.
Adjust Tension if Needed: Ensure the film holds boxes firmly without crushing them.
Cut and Clamp Film: Automatically completes the cycle.
Ready for Dispatch: The pallet or stack of boxes is stable, secure, and ready for storage or shipment.
Types and Variants
Semi-Automatic Pre-Stretch Wrapper
Operator starts and stops each cycle manually.
Fully Automatic Pre-Stretch Wrapper
Integrates with conveyor lines for continuous high-volume operations.
Best for large-scale factories and smart manufacturing setups.
Rotary Arm Pre-Stretch Wrapper
Arm rotates around a stationary pallet for tall or irregular loads.
Suitable for heavy or delicate items requiring minimal handling.
