Flat Mailers for Bulk Shipping

Partners Brand RM7 Flat Mailers are kraft-coloured envelopes measuring 17 by 21 inches, supplied in a pack of 50. They suit businesses that ship flat items such as documents, artwork or clothing in volume.

17 by 21 Inch Dimensions Determine Fit

The single specification that decides suitability is the 17 x 21 inch size; contents must lie flat within those edges. Buyers who need a larger or smaller envelope cannot use this pack.

Simple Seal, Watch for Overstuffing

Each mailer opens at the top and seals with the integrated adhesive strip, requiring no tools. Overfilling can split the kraft paper or prevent a secure closure, so keep contents flat and within the stated dimensions.
