Executive summary A door is two flat surfaces that take damage the second anything touches them. This machine wraps door panels in corrugated cardboard instead of film, folding a board around the panel, sealing the ends with glue and taping the top, then stacking the wrapped doors on a pallet. Panel sizes and stack height are configured per project.

Why cardboard instead of film
Film clings to a shape, but it does not carry a bump. A corrugated board stands off from the panel surface, and when the corner of a door meets a forklift mast, it is the board that takes the hit.
Cardboard also gives the package a clean, flat profile that stacks square on a pallet, which keeps the load stable around turns.
What the line does
The line takes a door panel in and returns it wrapped in cardboard. In sequence it feeds a pre-sized board, loads the panel, folds and shapes the board around it, seals the ends with glue, tapes the top, and pushes the finished package to a stacking point.
We engineer the whole run to operate without an operator touching the panel. A control system tracks the process in real time and flags a missed fold or misfeed before it becomes a damaged door.
Loading and feeding
A board feed draws pre-sized cardboard sheets into the wrapping area, one per panel. The panel is loaded automatically and positioned square to the board, so the wrapper folds onto a straight panel every cycle.
Folding and shaping
The board is folded and shaped around the panel to form a uniform enclosure, edge to edge. Because folding is mechanical, the package comes out the same shape at the start of a shift and at the end, which matters when wrapping runs for hours at high rate.
Sealing method
The package is closed with glue applied at the two ends and tape across the top. That is the joint that holds the board shut, and it replaces the film seals used on shrink lines.
Stacking and palletizing
Wrapped doors are lifted to the stack point and set on the pallet. The stack is kept square automatically, so the strapped pallet leaves square and the aisle stays clear.
Typical configuration
Figures below are common starting envelopes for this machine class and are confirmed per project.
| Parameter | Typical range, confirmed per project |
|---|---|
| Panel width and height | sized to the door envelope |
| Board size | pre-sized to the panel plus fold allowances |
| Sealing | glue at the ends, tape on the top |
| Output | paced to the line and stack height |
| Electrical supply | 380 V three phase 50 Hz, or 220 V single phase for lighter lines, selected per project to the plant supply |
What the video shows
Our footage shows a carton line folding a board around a door panel and moving the wrapped package to stacking. It is a general demonstration, so panel sizes, board grade and stack height for your doors are confirmed with us per project.
Selection checklist
| Question | Confirm per project |
|---|---|
| Door sizes | panel envelope and board cut |
| Board grade | corrugation matched to transit mode |
| Output rate | panels per hour |
| Stack height | pallet pattern and load height |
| Sealing | end-glue plus top-tape standard, sealing method tuned to shipping rigors per project |
| Electrical supply | voltage, phase and frequency on site |
Controls and safety
The line is run from a control panel with an emergency stop at the operator position. Keep hands clear of the fold and seal stations while the cycle runs, and follow the machine manual for board loading and routine inspection.
Engineering FAQ
Q: Do we still need film with a carton line? A: No. The board itself is the protective layer; glue and tape close the package instead of film seals.
Q: What doors does it handle? A: The line is sized to your door envelope per project, so it suits interior and exterior door panels within that range.
Q: How fast does it run? A: Speed depends on door dimensions, board feed speed and the stack-height cycle; the exact panels per hour are set during project engineering.
Q: Can it stack different sizes in one run? A: The stack pattern is set per project; mixed sizes need a changeover of the folding setup.
Q: What if a panel is slightly out of square? A: Panel positioning squares the piece to the board before folding; grossly warped panels are caught upstream.
