Layflat Bags

Clear layflat poly bags from 9 x 18 in. up to 48 x 54 in. — open-ended tubes with no closure, used for lining boxes and drums, bagging parts off a line, and covering finished goods.

Layflat bags are specified by width, length and mil thickness; heavier mil resists puncture, lighter mil costs less and conforms better. They close with tape, a heat sealer or a twist tie. The poly bag guide covers mil selection and sizing.

Buying by a Uline part number? See the Uline poly bag cross reference: Uline part numbers matched to our bags by size and mil. For every size we list, see the layflat bag size chart.

Questions about Layflat Bags

How many bags come in a carton?
Most of our layflat bags come 1,000 to a carton, but the count can change with size and thickness. Each size option on the product page shows its carton quantity, for example 10" x 15" in 1.5, 2, 3 and 4 mil, each 1,000 per carton.

Are these bags vented?
No. Our stocked layflat bags are non-vented, open-top bags. If you need vented bags, send a quote request with the size and thickness.

What thickness should I choose?
Thickness is listed in mil. Lighter items and parts usually go in 1 to 2 mil; heavier or sharp items in 3 to 4 mil, and 6 mil for the heaviest. Each size shows which thicknesses we stock.
