1) Understand the 3 key measurements
① Length
Measured laid flat. Determines how far the band stretches around an item.
② Width
Wider bands = stronger hold. Narrow bands = flexible, lightweight.
③ Thickness (Gauge)
Higher gauge = stronger, tighter. Lower gauge = softer, gentler.
Two bands with the same size number can behave differently depending on gauge.
2) Match band size to product circumference
Ideal band length = ½ item circumference
3) Choose strength
Standard, heavy-duty, or soft stretch depending on usage.
4) Choose the right material
Natural rubber, synthetic, or latex-free depending on environment.
5) Environment guide
| Environment | Recommended |
|---|---|
| Cold storage | High-latex natural rubber |
| Heat / sunlight | Synthetic / latex-free |
6) Common sizes
| Size # | Use |
|---|---|
| #16–#19 | Small items |
| #32–#33 | General packaging |
| #64–#117 | Postal & industrial |
7) Reduce breakage
- Store in cool, dry place
- Use correct length
- Choose high-latex blends for heavy use
