Common questions
Do these envelopes require moisture or water to seal?
No. These self-seal envelopes feature a pre-applied adhesive strip protected by a tear-off backing. Simply peel and press to seal, no water, moisture, or activation needed. This speeds up mailroom operations and eliminates seal failures caused by insufficient moisture.
What types of items fit in the 2-inch expandable depth?
The expandable sides accommodate documents, catalogs, books, product samples, small parts, and promotional items up to 2 inches thick. This versatility makes them ideal for diverse shipping needs while maintaining a professional appearance.
Are these envelopes USPS and carrier-compliant?
Yes. The 9 1/2 x 13" footprint and self-seal construction meet USPS, UPS, and FedEx standards for automated mail sorting and handling. The durable 40 lb. kraft stock withstands commercial processing equipment without tearing or jamming.
How long does the adhesive stay effective when stored?
The tear-strip backing protects adhesive from dust and moisture, extending shelf life significantly compared to standard envelopes. When stored in a dry environment, these envelopes maintain reliable seal quality for 12+ months.
