Pad-Kraft Quick-Load® side-loading padded shipping mailers are from Astro-Valcour (Glens Falls, NY). Side loading eliminates the pushing and manipulating often associated with stuffing mailers from the top.
A peel-away strip for self sealing further simplifies loading. Available in sizes from 4" x 9" to 141/2" x 21". Cushioning material consists of a macerated liner made from recycled paper surrounded in a kraft paper outer liner.
