1.5 Mil Poly Bags for Amazon FBA

If you have looked up Amazon FBA poly bags, you have probably seen the words "1.5 mil." That number is the thickness of the bag, and it is one of the first rules Amazon lists for poly-bagged units.

This post explains what 1.5 mil means, how it compares with 1 mil and 2 mil, and what else still matters when you pick a bag. It is not a full requirements checklist. For that, use our Amazon FBA poly bag requirements guide, and check Amazon's help in Seller Central before you ship.

What 1.5 mil means

A mil is one thousandth of an inch. So 1.5 mil is 0.0015 inches of plastic film.

It is a thickness measurement, not a bag size. Size is the width and length, such as 10x12. Thickness is how heavy the film feels when you hold the bag.

You cannot judge thickness well by eye. If you need to confirm it, suppliers list the mil on the product page, and a micrometer can measure the film. Our bags are sold as 1.5 mil.

Why Amazon lists 1.5 mil

Amazon's packaging and prep help says the thickness of an FBA poly bag must be at least 1.5 mil (a thousandth of an inch). That is a minimum, not a target you have to stay under.

In plain terms, Amazon does not want a very thin bag that can tear too easily in a fulfillment center. Buying bags that are already made to 1.5 mil means you are not guessing with leftover thin film or a retail bag that does not list its thickness.

Rules can change. Check that help page in Seller Central for your item before you ship. We do not promise that a 1.5 mil bag, by itself, will be approved for every product.

1 mil vs 1.5 mil vs 2 mil

People also search for how 1.5 mil compares with other thicknesses. Here is the simple version, based on the number itself and on Amazon's listed minimum. This is not a lab test, and we are not claiming how any bag will perform in shipping.

1 mil. 1 mil is thinner than 1.5 mil. It is below the minimum thickness Amazon lists for FBA poly bags. If you are prepping FBA inventory, a 1 mil bag is not a match for that rule.

1.5 mil. This is the minimum thickness Amazon lists. It is a common choice for FBA poly bags used on apparel, accessories, and many boxed smalls. Supply Legends bags are 1.5 mil.

2 mil. 2 mil is thicker than 1.5 mil. A thicker bag can still meet the minimum thickness rule, because 2 is more than 1.5. Thicker film often costs more and can feel stiffer. Amazon's listed rule is "at least 1.5 mil," not "must be 2 mil." Pick 2 mil only if you want a thicker bag for your item, not because the minimum requires it.

We sell 1.5 mil bags, not 1 mil or 2 mil.

Thickness is only one of the bag rules

A 1.5 mil bag can still cause a problem if it is the wrong size, left open, or missing a warning. Amazon's packaging help also says:

  • The bag should be clear, so a barcode can be scanned through it, or the barcode should be on the outside of the bag.
  • The bag must be completely sealed, with tape or an adhesive strip.
  • The bag should not stick out more than 3 inches past the item.
  • Bags with an opening of 5 inches or more, measured flat, need a suffocation warning, printed on the bag or attached as a label.

Adult products are a separate case and need opaque bagging. Check Seller Central for that category.

All 14 of our sizes are 5 inches wide or more, so each bag has the suffocation warning printed on it, in English, Spanish, and French. "Ready to Ship" is also printed on the bag.

For self-seal bags and the printed warning, see self-seal poly bags with a suffocation warning. To pick a size, see what size poly bag you need for Amazon FBA.

FAQ

How thick is 1.5 mil plastic?

1.5 mil is 1.5 thousandths of an inch, or 0.0015 inches. It is a film thickness, not a width or length.

Are 1.5 mil poly bags thick enough for Amazon FBA?

Amazon lists 1.5 mil as the minimum thickness for FBA poly bags. Thickness is only one rule. You still need a clear, fully sealed bag that fits the item and has a suffocation warning when the opening is 5 inches or more. Check Seller Central for your item.

Is 2 mil better than 1.5 mil?

2 mil is thicker than the minimum Amazon lists. That does not automatically make it the right bag for every item. It may cost more. We sell 1.5 mil bags.

Do your 1.5 mil bags include a suffocation warning?

Yes. The warning is printed on every bag in English, Spanish, and French. A printed warning is not, by itself, a guarantee that a shipment will pass. Check Amazon's current warning rules in Seller Central.
