Self-Seal Suffocation Warning Poly Bags

Self-seal poly bags with a suffocation warning save a step in prep. The warning is already printed on the bag, and you close it with the built-in strip. No extra tape and no warning stickers.

Here is what that means, how the bags work, and how to pick a size from our 14 options.

What "self-seal" and "suffocation warning" mean

Our bags are clear 1.5 mil polyethylene with a lip and a permanent adhesive strip. Peel the strip, fold the lip over, and press. The seal does not reopen. Length is measured below the lip.

The suffocation warning is printed on every bag in English, Spanish, and French. "Ready to Ship" is also printed on the bag.

Amazon says FBA poly bags must be at least 1.5 mil, clear, and fully sealed, and that bags with an opening of 5 inches or more need a suffocation warning. The bag should not stick out more than 3 inches past your item. (Amazon staff answer; staff answer on the 3 inch rule.) Rules can change, so check Seller Central for your item before you ship.

All 14 of our sizes are 5 inches wide or more, so each bag has the warning printed on it.

Our sizes

We sell 14 sizes, from 5x10 to 24x30, in packs of 100, 500, or 1000. Shop all of them on the poly bags order page.

To pick a size, measure your item in inches, then use: bag width = item width + item height + 1 inch, and bag length = item length + item height + 1 inch. If you land between sizes, go up one size, but keep the bag within 3 inches of the item. This is a starting point, so measure first.

• 5x10 and 6x9 for small, slim items
• 8x10 and 9x12 for kids' clothes, books, and small boxes
• 10x12, 10x15, and 11x14 for adult shirts, hoodies, and folded jeans
• 12x18 and 14x20 for pants, light jackets, and larger boxed items
