Poly mailer size guide

Start with the packed item, including any inner bag or wrapping. Measure its width, length, and thickness. A flat mailer needs extra room around the thickness and enough space to close the seal without stretching.

Illustrative measurement example (not a tested fit): an item measuring 8 × 10 × 1 inches needs more than an 8 × 10 flat bag. Compare a 10 × 13 mailer as a starting point, then test the packed item: it should slide in easily and the flap should seal flat without pulling on the seams.

These are starting points, not guaranteed fits or usable internal dimensions. Fabric, wrapping, seams, and the sealing flap affect fit. Check the product details and test one packed item before ordering in quantity. Choose protective packaging suited to fragile or sharp items.
