The right choice comes down to three simple questions: is metal allowed in your environment? How long does the label need to stay in place? Is the item handled, stored under cover or exposed outdoors? Rayon string is the clear choice whenever metal is banned or undesirable: food industry, textiles, fragile goods, products handled by hand. Metal ties take over when hold is the priority: industrial equipment, frequently moved assets, outdoor storage.
| Criterion | Rayon string | Metal wire ties |
|---|
| Material | Metal-free (rayon) | Galvanised rust-proof steel wire |
| Fitting | Knotted, no tools | Twist-on, no tools |
| Sensitive environments | Ideal food industry, textiles | Best avoided |
| Outdoor / industrial | Indoor use recommended | Suitable, long-lasting |
| Reusability | Unties and can be reused | Removed by untwisting |
| Typical use | Batches, samples, stocktaking | Pallets, equipment, exposed assets |
In the field, the two ties are complementary rather than competing: rayon string for internal flows and batch identification, metal wire ties for exposed or high-value equipment. By equipping your labelling station with both references, you cover every scenario without improvising. Structuring the traceability of a warehouse? RFID labels complete this setup, and a well-run RFID inventory makes your stock counts more reliable.
