Sizes & Microns Guide (What Thickness Do I Need?)
Poly bag thickness is measured in microns (µm). As a simple rule: lighter items = lower microns, sharper/heavier items = higher microns.
| Use Case | Typical Microns (µm) | Popular Sizes (mm) | Shop |
|---|---|---|---|
| Apparel, documents, soft goods | 30–40 µm | 100×150, 150×200, 200×300 | Standard LDPE |
| Small parts, hardware kits | 40–60 µm | 100×150, 125×200, 150×225 | Press-seal (zip) |
| Heavier/irregular items, sharper edges | 75–100+ µm | 200×300, 300×450, 460×600 | Heavy-duty |
| Custom continuous lengths | Varies by tubing | 150–600 mm widths (rolls) | Poly tubing |
Food-Grade & Heavy-Duty Options
Select sizes are available in food-grade LDPE (clear). For heavier or sharper items, choose our heavy-duty microns for extra puncture and tear resistance.
How to Seal Poly Bags
- Heat seal (recommended for speed and consistency)
- Press-seal (zip) closure for reusability
- Tape, staples or twist ties for quick close-off
