How Does Poly Tubing Work?
Poly tubing is a continuous tube of polyethylene film wound on a roll. Unlike pre-made bags with fixed dimensions, you control the length:
- Measure your item and add 2-3 inches for sealing
- Cut the tubing to your required length
- Seal one end with a heat sealer, twist tie, tape, or staple
- Insert your product and seal the other end
This flexibility eliminates the need to stock dozens of bag sizes—one roll of tubing handles everything.
What Thickness Do I Need?
| Mil | Thickness | Best For |
| 1 mil | 0.001" | Lightweight items, dust covers, temporary protection |
| 1.5 mil | 0.0015" | General purpose, textiles, soft goods |
| 2 mil | 0.002" | Standard industrial use, most common choice |
| 3 mil | 0.003" | Heavy items, moderate puncture resistance |
| 4 mil | 0.004" | Sharp edges, heavy parts, long-term storage |
| 6 mil | 0.006" | Maximum protection, industrial/cleanroom applications |
Poly Tubing vs. Pre-Made Bags: Which Should I Choose?
Choose poly tubing when:
- Your products vary in length (posters, rods, lumber, pipes)
- You package custom or made-to-order items
- You want to reduce bag inventory and simplify purchasing
- You need to minimize packaging waste
Choose pre-made bags when:
- You package the same-sized items repeatedly
- Speed is critical (no cutting/sealing required)
- You need printed or specialized bags
