A blank is provided for making an insert that satisfies the USPS requirement that a flat-sized mail piece be uniformly thick so that any bumps, protrusions or other irregularities do not cause more than ? variance in thickness. In one embodiment, when folded, the blank forms an insert with spacers about a quadrant that receives a good to be mailed. In other embodiments, when folded, the blank forms an insert with sleeves into which goods may be slid, or an insert with sleeves with closed ends and into which goods may be inserted into cutouts in the sleeves.

A method for manufacturing flexible bags, including: a first strip of flexible material is unwound as a continuous sheet in a longitudinal direction; a hem is formed on each edge of the first strip and the hems are glued over at least one length of a first or a second flap on one stitching face; a fold is formed in the first strip along a transverse folding line to fold down the first flap over the second flap against an internal face of the first strip, the fold bringing, for each edge, hem against hem so as to obtain the bonding of the hems, the strip is cut along a transverse section to form the bag at the end of the operations. Machine implementing the method and bag thus obtained.
