How to choose the right size
Bubble mailer numbers explained
Bubble mailers are sold by bag number: #000 is the smallest (4" x 8") and the numbers go up with size, through #7 (14.25" x 20") and the large #8, #9 and #10. The numbers are an industry convention, so check the actual inches before you order; sizes can vary slightly between brands.
Poly or kraft?
Poly bubble mailers are water-resistant and tear-resistant, and come in many colors. Kraft bubble mailers have a paper outside and use the same bag numbers, #000 to #7; see each kraft page for its exact size. For items that don't need padding, like clothing, flat poly mailers are lighter and cost less per mailer.
