Frequently Asked Questions

What is the difference between the 10x13 bag and the 10x13+1.5 Lip version?

The "+1.5 Lip" designation indicates the lip extends 1.5 inches above the 13-inch bag body. This longer lip provides a wider sealing surface for auto-sealing equipment and gives more material to work with when hand-sealing at speed during direct mail production. The interior capacity is the same as a standard 10x13 bag — the lip length only affects the seal area above the bag opening.

What direct mail pieces fit in a 10x13 poly mailing bag?

The 10x13 interior fits standard 8.5x11 promotional flyers, tri-fold brochures, folded newsletters, real estate postcards, and retail circulars. Multiple flyers or a flyer with a small insert can be combined as long as the total insert thickness stays within USPS flat mail limits for automated sorting eligibility.

Why use poly bags instead of paper envelopes for direct mail?

Poly mailing bags provide a moisture-proof barrier that protects printed pieces from rain, humidity, and handling during postal transit. The clear film allows envelope content to be seen before opening, which can increase engagement rates for promotional mail. Poly bags also resist tearing better than paper envelopes under the stress of automated mail processing equipment.
