C4 A4 Board Backed Envelopes Manilla 12" X 9"

In many instances, documentation, files and certificates can be just as important as products and physical items, which is why you should invest in hard-backed envelopes to afford a high level of rigidity and protection.

Featuring a hard-wearing manilla Kraft exterior (measuring at 115 GSM), these hard-backed envelopes are one of the safest ways to send certificates and other sensitive documents. They even incorporate hot melt peel & seal strips for extra tamper prevention and increased peace of mind. As standard, “Please do not bend” is also printed on each envelope in a bold red typeface for added protection throughout the delivery process.

Designed to be written directly on, or used with stick-on address labels, our hard-backed envelopes are a quick and easy packaging method with a professional finish, helping to make sure your important documents make the right impression.
