The Heavy Duty Book Wrap Mailer (350mm x 260mm x 70mm) is designed to provide secure and reliable protection for larger books, documents and flat products during shipping. Made from strong corrugated cardboard, these mailers help safeguard items from damage throughout the delivery process.

Featuring an adjustable wrap-around design, the mailer expands to accommodate the height of your contents while maintaining a snug and secure fit. This helps minimise movement inside the package and provides added protection during postal and courier handling.

Quick and easy to assemble, these mailers are ideal for busy packing environments and are widely used by e-commerce businesses, publishers and fulfilment centres sending larger flat items.
