Description

Send A4 documents with both protection and address visibility using our White Windowed C4 / A4 Board Backed Envelopes. These are premium hard backed envelopes combining the rigidity of board backing with a clear address window — ideal for professional mailings, invoices, and documents that need visible recipient details. This listing is for bulk quantities, perfect for businesses, accounting departments, legal firms, and high-volume mailers.

Key Features & Construction

  • Dimensions: 324 × 229 mm (C4 size) — fits full A4 paper flat, no folding required

  • White outer shell: Clean, business-style appearance; printed “Please Do Not Bend” warning (if applicable)

  • Clear address window: Positioned to show address fields on A4 inserts without manual labeling

  • Rigid board backing: Protects contents from bending or creasing in transit

  • Closure: Secure peel & seal flap or gummed closure (depending on variant)

  • Bulk packaging: Available in volume packs (e.g. 125, 250, 500, 1,000 units or more)

What Fits Inside & Use Cases

This size and add-on of a window make this envelope ideal for:

  • Full A4 documents like invoices, contracts, statements, and reports

  • Certified letters and legal paperwork where address needs to be visible

  • Brochures, catalogues, and promotional literature

  • Printed proposals, quotations, and client packs

  • Photographs or art prints (kept flat by the board backing)

  • Certificates, menus, or portfolios that must look professional and flat

Because the board backing keeps contents stiff, your documents won’t bend or warp — and the window eliminates the need for address stickers or extra labeling.

Why Bulk Orders Matter

  • Reduced per-unit cost — purchasing in bulk significantly cuts cost per envelope

  • Consistent stock — always ready for mailing campaigns or monthly dispatches

  • Uniform quality — each unit meets the same protective and visual standard

  • Packing & fulfillment efficiency — easier to store, pick, and ship at scale
