International Plastics offers over 400 sizes of lay flat poly bags. Lay flat bags come separated in boxes of 1,000 unless otherwise noted. Poly bags are measured width first and length second for example 8' wide x 10" long. The sizes are from side to side and seal to top but can vary due to manufacturing tolerances of up to 1/4 inch on each dimension. Lay flat bags can be bottom sealed or side sealed depending on the size and bag machines they have been converted on. Larger sizes (24” and above) are almost always bottom sealed
