What are Board Backed Envelopes?


Quite simply they are paper fronted envelopes that have card backs to add rigidity & protect their contents. The card back or grey board back can seriously enhance the strength of the envelopes & also lends itself to another name for them - card backed envelopes.


We produce board backed envelopes in various sizes to suit a range of items that clients post.


Different manufacturers & distributors of board backed envelopes produce them in a range of qualities. Here at Defendapack we produce premium quality envelopes with strong paper fronts and heavy duty board backs. When deciding on which board backed envelopes to purchase pay particular attention to the specification: as poorly specified envelopes will perform poorly & fail to protect their contents sufficiently.


We supply C6 A6 Classic Board backed envelopes,  C6 A6 PiP or postcard size board backed envelopes, C5 A5 Classic board backed envelopes, C5 A5 PiP board backed envelopes, C4 A4 board backed envelopes and C3 A3 board backed envelopes.
