Strongest Defenda Brown All Board Mailers or Capacity Book Mailers.
Defenda premium strength brown all board envelopes are designed to further improve protection levels for items you don’t want bent in the mail. The 400 gsm board used in their construction provides a rigid mailer that delivers fabulous protection & will withstand all but the harshest treatment. The convenient peel & seal closure makes large mail-outs simple & quick — like with our board backed envelopes — but with improved strength, and extra capacity for thicker items. They can of course be combined with C5, C4 & C3 stiffeners for customers wishing to enhance rigidity still further. So if you are looking for the strongest C3, C4 or C5 envelopes then Defenda Brown All Board Envelopes will be the perfect choice for you. All of our Capacity Wallets come with a red ripper strip for easy opening.
All of our brown all board envelopes / capacity book mailers are manufactured from 100% recycled board.
