Description

Protect your large documents with our C4 / A4 board backed envelopes — premium hard backed envelopes engineered for rigidity and postal resilience. This listing is for bulk quantities, perfect for businesses, publishers, print shops, galleries, or any operation needing a dependable supply of rigid mailers.

Key Features & Specifications

  • Outer size: 324 × 229 mm (C4 format), sized to accept A4 sheets without folding.

  • Construction: 1000 µm board backing combined with a 120 gsm paper shell, striking a balance between stiffness and weight.

  • Closure: Peel & seal flap for fast, secure sealing.

  • “Do Not Bend”: Often printed on the face to warn handlers and reduce mishandling.

  • Bulk packaging: Available in multiples (e.g. 125, 250, 500, 1000+) to deliver economies of scale.

What Fits Inside & Use Cases

Because of its generous dimensions and rigid build, the C4 / A4 board backed envelope is ideal for mailing:

  • Flat A4 documents (e.g. reports, brochures, contracts, legal papers) without folding

  • Artwork, drawings, and prints up to A4 size

  • Certificates, diplomas, menus, portfolios

  • Magazines, catalogs, booklets (if thickness allows)

  • Mounted photos or mounted art prints (provided total thickness fits)

The hard backing ensures your contents remain flat, protected from creases, bends, and postal damage.
