Executive summary Stainless coils mark easily, so a line that wraps and stacks them without hand handling protects the surface finish. Our line in this video carries stainless coils on rollers to an automatic wrapper, where an applicator arm lays clear film over each coil, then stacks the wrapped coils on pallets. For a wrap through the eye, film per coil follows from the wraps round the coil times the section perimeter.

What the video shows
Stainless coils, eye horizontal, travel on conveyors and turning platforms towards the wrapping station, with operators at the line.
At our wrapper, which has a yellow frame and green panels, the film applicator arm lays clear film across the coil until it is covered with a clear film finish. At the end of the line the wrapped coils are placed on wooden pallets and stacked, with floor markings showing the pallet positions. The Fhopepack.com label is on the wrapping machine.
How a coil goes through the line
Times are read from the video timestamps.
| Step | What happens | Video time |
|---|---|---|
| Handling | Coils travel on conveyors and turning platforms | about 2–24 s |
| Into the wrapper | The coil reaches the wrapping station | about 26–28 s |
| Wrap | The applicator arm lays clear film over the coil | about 30–66 s |
| Stack | Wrapped coils are placed and stacked on pallets | about 68–78 s |
The coil is not lifted by hand between stations, which keeps its edges and faces free of marks.
Film per coil
Illustrative example, for film wrapped through the eye:
| Item | Value |
|---|---|
| Outer and inner diameter (illustrative) | 1,200 and 508 mm |
| Coil width (illustrative) | 300 mm |
| Coil wall, (1,200 − 508) ÷ 2 | 346 mm |
| Section perimeter, 2 × (346 + 300) | 1,292 mm |
| Mean circumference, π × 0.854 m | about 2.68 m |
| Advance per wrap (illustrative) | 100 mm |
| Wraps, 2,680 ÷ 100 | about 27 |
| Film laid, 27 × 1.292 m | about 34.9 m |
A smaller advance per wrap gives more overlap and more film per coil.
Controls and safety
Coils move on powered conveyors, the applicator arm works round the coil and the stacker places full coils. Keep people outside the stations while the line runs, and enter only with it stopped and isolated.
The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines.
Selection checklist for a stainless coil wrapping and stacking line
- Coil outer and inner diameter and width range.
- Heaviest coil.
- Film type and overlap for the surface finish.
- Labelling needs.
- Coils per stack and pallet type.
- Coils per shift.
Engineering FAQ
Q: What does the line do? A: It moves stainless coils to an automatic wrapper and stacks the wrapped coils on pallets.
Q: How much film does a coil take? A: Wraps times section perimeter: 27 × 1.292 m gives about 34.9 m in our example.
Q: How many wraps go round a coil? A: Mean circumference over advance per wrap: 2,680 ÷ 100 mm gives about 27.
Q: Why avoid hand handling? A: Stainless faces and edges mark easily; rollers and the stacker keep hands off.
Q: Can it take my coil sizes? A: Send the coil diameters, widths and weights and we lay out the line.
Next step
We plan your stainless coil wrapping and stacking line in three steps:
- Submit your layout drawing with coil diameters, widths and weights to info@fhopepack.com.
- Receive a proposal within 48 hours, with film, overlap and labelling.
- Book a site survey to check stacking plan and coils per shift.
