Adaptable and flexible envelopes
RAJA cardboard capacity mailers are designed to expand from flat to a thickness of up to 80mm, so they can hold thicker items than standard cardboard alternatives. This expandable cardboard envelope suits books, photo albums, CDs, DVDs, games and phones. They're made from 380gsm solid micro-flute cardboard with a recycled outer that holds its shape and protects corners and faces in transit. Used flat it suits slim items, and the gusset extends to give depth for thicker media. An adhesive strip seals the mailer securely and airtight, and a tear strip lets the recipient open it cleanly without cutting the contents. Four sizes run from 150 x 130 x 80mm to 320 x 250 x 80mm. The board is 100% recyclable.
Sold in packs of 100, priced per pack, and delivered boxed.
Where do capacity book mailers work best?
Capacity book mailers suit packing benches handling mixed media orders, from flat items to products up to 80mm thick, without changing pack format.
- Books and photo albums, where rigid 380gsm micro-flute cardboard protects corners and faces in post and courier handling.
- DVDs, CDs and games, where the expandable depth takes multiple cases.
- Mobile phones and small boxed electronics, where the carton envelope stays compact and the adhesive strip closes it securely.
- Mixed e-commerce orders, where one mailer runs flat for slim items or expands for thicker goods.
Not for
- Items thicker than 80mm. Use a postal box with the right internal depth.
- Loose fragile items without cushioning. Add void fill or wrap or use a stronger cardboard box.
- Liquids or products that can leak. Use sealed inner packaging before the outer pack.

Choose the right cardboard mailer
These capacity book mailers are perfect when media and small goods need expandable depth to 80mm.
- Choose an expandable cardboard envelope when you need to alternate between shipping flat items and items up to 80mm thick that can be sealed with an adhesive strip.
- Choose cardboard mailing envelopes when contents are under 40mm and need less depth in the same adhesive-and-tear style.
- Choose a tamper proof envelope when you need a tamper-evident closure with locking flaps rather than an adhesive strip.
- Choose a rigid mailer, with a short edge when items are flat and need solid board rather than expandable depth.
FAQs

How thick an item will they take?
Flat items up to 80mm thick, using the gusset only where the depth is needed.
