Poly Bagging Rules: Suffocation Warnings and Thickness Standards
Poly bags are one of the most common prep protections for plush, apparel, liquids, and loose units. Using incorrect bag specs can cause rejection risk and avoidable safety issues at receiving.
1) The 1.5 Mil Rule
Amazon requires poly bags to be at least 1.5 mil thick. Very thin bags tear too easily during handling. For heavier units, 2.0 mil is often more reliable.
2) Suffocation Warnings
Any bag with an opening of 5 inches or larger needs a visible suffocation warning. This can be printed directly on the bag or added as a compliant label.
Example text: "WARNING: To avoid danger of suffocation, keep this plastic bag away from babies and children."
3) Special Rules for Apparel
Apparel should be protected in transparent bags so the item can be verified without opening the unit. If hangers are used, bag selection must still allow proper sealing and safe handling.
4) Recommended Bag Sizes
These core bag sizes cover most common inventory profiles:
| Size | Best For |
|---|---|
| 6 x 9 in | Cosmetics, small toys, vitamins |
| 9 x 12 in | T-shirts, books, DVDs |
| 11 x 14 in | Hoodies, larger toys, multipacks |
| 19 x 24 in | Backpacks, bedding, coats |

Can I use Ziploc bags?
They can be acceptable if clear and thick enough, but permanent-seal prep bags are generally preferred for security and consistency.
