Board Backed Envelopes

Board backed envelopes are protective envelopes which are backed by a rigid board. Board backed envelopes keep fragile, important or otherwise precious documents safe from damage or wear. Use board backed envelopes to send or store valued documents such as qualification certificates, contracts or maps. Peel and seal system secures the envelope neatly and without fuss.

The board backed envelope range at Paperstone

You can choose between manilla and white board backed envelopes. A wide range of sizes is available from the smaller 190x140 to C3 (457x324 which will accommodate A3 paper size documents. The most popular size is C4 (for A4-sized documents). C4 board backed envelopes are also available with an address window. Board backed envelopes are sold in boxes of 50 or 125.

Envelope fact

“To push the envelope”, meaning to exceed current levels of performance or to innovate, emerged in a corporate jargon context in the late 1980s. But the term originated about a decade before in aviation circles: “Pushing the envelope” here signified achieving higher altitudes or testing a craft's capabilities in a flight test.
