Panoramica
To choose a packing material combination for steel wire packing, start from how the coil is wound and how far it must travel. For short, clean trips stretch film alone protects the coil surface; for long storage or sea transport a VCI rust-protection paper is the usual answer; and strapping is planned at 1 to 3 straps per coil. Every choice is confirmed per project. This guide lays out the material options, the selection logic, and the data to send, and is written for wire processing and coil mill engineers.
The video below shows the steel wire coiling machine in the family — long wire is wound into compact coils that are then packed with the material combination you choose:
Why Material Choice Starts at the Coil
Il materiale di imballaggio deve corrispondere al modo in cui il filo d'acciaio esce dalla macchina. Una bobina avvolta strettamente mantiene la sua forma e necessita solo di una pellicola superficiale, mentre una bobina allentata o pesante richiede un fissaggio più robusto e una protezione maggiore.
| Condizione della bobina | What the packing must cover |
|---|---|
| Tightly wound, stable coil | A surface film keeps the outside clean; light strapping holds the ring |
| Avvolgimento allentato | Extra strapping keeps the layers together |
| Heavy or large coil | A stronger cover, with strap count raised where stability needs it |
| Long storage or sea transit | A rust-protection grade, not film alone |
La pellicola e la cinghia avvolgono la bobina, mantenendo i fili uniti e la superficie pulita dal momento della produzione fino al punto di consegna. Il materiale di imballaggio e il numero di cinghie vengono confermati per ogni singolo progetto.
Selecting the Material Combination
| Trip and storage | Material combination, confirmed per project |
|---|---|
| Short, clean trip, indoor | Stretch film; 1 to 3 straps per coil |
| Longer handling and stacking | Film with strap reinforcement; strap count from coil width, diameter and stability |
| Lunga conservazione | VCI rust-protection paper; 1 to 3 straps per coil |
| Trasporto marittimo | VCI rust-protection paper in a full cover; strap plan confirmed to the route |
| Coated or finished wire | Film or paper grade chosen so the surface is not marked |
VCI (volatile corrosion inhibitor) paper protects the wire surface during long storage and sea transit, while stretch film suits short, clean trips. Film and paper grades are confirmed per project.
Lista di controllo per la selezione
| La Domanda | Confermare per progetto |
|---|---|
| Gamma di fili | Wire diameter and coil outer and inner size |
| Tipo di bobina | Round coil or flat ribbon, and ring form |
| Film | Stretch film for short trips, VCI rust paper for long storage |
| Cinturini | Da 1 a 3 per bobina, selezionati in base a larghezza, diametro e stabilità della bobina. |
| Control and line | Panel layout, speed setting and emergency stop |
| Fornitura elettrica | Tensione, fase e frequenza in loco |
Cosa mostra il filmato
Our footage shows the automatic steel wire coiling machine that winds long wire into compact coils: the wire is drawn from a pay-off reel through guide rollers and tension wheels, wound onto a take-up spool, and a machine arm moves the finished ring clear. It is a general demonstration of the coiling step — it does not show a material-selection process. Your wire size, coil type and packing material combination are confirmed with us per project.
Matching Material to the Coil
| Caratteristica della bobina | Material approach (confirmed per project) |
|---|---|
| Light/medium, tidy winding, short transit | Stretch film, single layer or two passes |
| Long storage or sea transit | VCI rust-protection paper or film |
| Loose or heavy coil, high spring-back | Extra strapping (PP for light-medium, PET or steel band for heavy/high-tension coils) plus film |
| Rischio di danni ai bordi | Edge protectors or buffered guides added to the wrap |
FAQ
Q: What is the simplest packing choice for steel wire?
A: For short, clean trips stretch film alone protects the coil surface; state the trip and storage route so the film grade is confirmed.
Q: When do I need VCI paper?
A: VCI rust-protection paper is the usual choice for long storage or sea transport, where rust protection matters.
Q: How many straps does a coil need?
A: Strapping is planned at 1 to 3 straps per coil, chosen from coil width, diameter and stability.
Q: What does the coiling machine do?
A: It winds long steel wire into compact coils and transfers the finished ring for the next step.
D: Quali norme di sicurezza si applicano?
A: Ask the supplier for the machine's safety documentation and CE certification status as part of the quotation; the guide itself is about material selection, so certification is confirmed on the project, not assumed.
Passo successivo
Send your wire diameter and coil type, the transit route (short clean trip, long storage or sea transport), and the target strap count, so the film or paper grade and strap plan are confirmed for your coils.
