• Ensure your mailings are protected throughout transit with our heavy duty Conformer expansion rigid mailers, made using sturdy 14pt white paper board that resists bending or folding so your documents and booklets stay secure.
• Mail documents of varying thickness using the same expansion envelopes thanks to the score lines on all four sides of each mailer, which allow the envelope to expand uniformly and conform its size to a perfect fit for the contents inside.
• Ship with confidence when you use our large extra durable Conformer envelopes, which measure 9.75 x 12.25 inches. Each glue seam is inset from the edges to increase the strength of the mailer, unlike how traditional mailers are constructed with weak glue seams along the edges.
• Create a professional, tailored look when shipping everything from thin documents or booklets to thick stacks of papers or even books up to 5/8¡± thick. The corners of Conformer mailers are uniquely constructed so they expand seamlessly at the bottom corners up to 0.625 inches thick.
• Our pack of 25 conformer envelopes stores flat while providing unmatched versatility when mailing items with varied thicknesses, replacing the need for expensive gusseted envelopes, Tyvek mailers, padded or bubble mailers, and boxes that take up a lot of room in your supply closet.
