Description
Our A4 postage bag is a 120gsm kraft paper mailing bag measuring 350 x 250mm with a 50mm gusset and a 96mm flap. Two peel-and-seal strips let your customer reuse it for a return, and a tear strip makes opening easy. Box of 100, made in Germany.
Same bag, other pack sizes: pack of 20, pack of 50, pack of 250. Each A4 postage bag is lighter and flatter than a box, which usually keeps postage down for clothing and soft goods.
