Mil thickness helps match a poly bag to the weight, edges and handling demands of the product inside. Thinner film favors flexibility and material efficiency; heavier film adds resistance to punctures, tears and repeated handling. Gauge is important, but it must be selected together with bag dimensions, construction and closure. One mil equals one-thousandth of an inch. A higher number means thicker film, not a guaranteed weight capacity. Two products of similar weight can place very different demands on a bag when one has rounded surfaces and the other has sharp corners, threads or machined edges. These ranges are selection starting points, not load ratings. Test the filled bag through the actual packing, storage and shipping process when failure would damage the product or interrupt production. Measure the product at its widest points and include depth created by stacked, folded or irregular contents. Leave usable length for the intended zipper, heat seal, tie, tape or fold. Overfilling can stress both the film and closure even when the gauge is otherwise appropriate. Choose Flat Poly Bags for open-top general packaging or compare Reclosable Poly Bags when repeated access is part of the workflow. A mil is one-thousandth of an inch and describes film thickness. No. Product shape, edges, bag size, closure and handling all affect performance. Not automatically. Thicker film can help, but exposed points may still require caps, wrapping or rigid protection. It changes film thickness, not the listed width and length; the product still needs to fit without stretching the bag or closure. We can help you compare product fit, edges, handling and closure requirements.
