6" x 9" Mailing Envelopes
Avoid delay and surcharges for routine First Class Mail over 1/4" thick
Save postage on 3 ounce documents. Avoid returned mail.
USPS rules add cost to each mailing more than 1/4" thick or in a standard envelope larger than 6" x 9".
Many multi-page documents when folded to a #10 envelope incur a surcharge because they are more than ¼" thick. If you don’t include the surcharge your mail could be returned and delayed. If you mail the document without folding, in a 9"x 12" envelope, you jump out of the thickness surcharge frying pan into the first class large envelope fire of added postage. With our 6"x 9" envelopes you can fold the document once and pay only first class letter postage, saving the thickness surcharge or the extra postage for large envelopes.
Now that’s a good reason to start using our 6"x 9" envelopes.
They’re available in 14 lb. Tyvek® green diamond First Class open end (Cat. No. 817) and 24 lb. white wove open end (69OE) and booklet (69BK).
