Wrapping machines play a crucial role in the efficient and protective packaging of PU (polyurethane) sandwich panels. The primary function is to securely encapsulate bundles of panels, preparing them for storage and transportation.

wrapping machine bundle packing process for PU panels:

1. Product collation and grouping

Panel Stacking: PU panels are typically stacked together to form a bundle, creating a suitable unit for wrapping and transport.

Bundle Forming: The stacked panels are arranged into a group, creating a compact bundle ready for wrapping.

2. Wrapping

Stretch Wrapping: This method is widely used for larger items like PU panel bundles.

The machine uses stretch film (typically LLDPE) dispensed from a rotating carriage.

As the bundle passes through the machine horizontally, the film is applied circumferentially, creating a tight and protective layer.

Modern systems often employ pre-stretch mechanisms to increase film yield and load containment, improving efficiency and reducing material consumption.

3. Discharge and further handling

Outfeed: The wrapped bundle is discharged onto an outfeed conveyor, ready for stacking on pallets or further processing.

Benefits of automated wrapping for PU panels

Enhanced Protection: Wrapping safeguards panels from moisture, dust, scratches, and other damage during handling, transport, and storage.

Improved Load Stability: Wrapping unitizes the bundles, preventing shifting and enhancing safety during logistics.

Increased Efficiency and Productivity: Automated machines significantly reduce manual labor and accelerate the wrapping process, improving throughput.

Reduced Material Costs: Pre-stretch capabilities maximize film yield and reduce consumption, lowering overall costs.

Improved Professional Presentation: Consistently wrapped products present a more professional image.

Reduced Labor Costs and Strain: Automation reduces the need for manual labor and minimizes the risk of injuries.

Features:

The movement of the bundles (panels) is done by using the roller having the height of 700 mm

The circular motion packing is controlled by the electrical drive.

Two no’s of stretch film (500 – 600 mm Width) setup is used to pack the bundles.

This machine will pack all the four sides.
