Benefits and Features of Cardboard-Backed Envelopes

Cardboard-backed envelopes provide the necessary rigidity to ensure that the contents inside arrive at their destination without folds, creases, or damaged corners.

Thanks to their high-density materials and heavyweight GSM (typically above 110g/m²), these envelopes offer superior protection. The sturdy cardboard backing enhances security, making them ideal for shipping delicate and valuable documents.

Common Uses for Cardboard-Backed Envelopes

These envelopes are widely used for sending printed materials that require extra protection, such as:

• Photographs, posters, and graphic materials
• Magazines, catalogs, and professional brochures
• Certificates, diplomas, and legal or commercial documents
• Awards, recognitions, and client or partner appreciation letters

The self-adhesive closure with a protective strip ensures a strong and secure seal, preventing accidental opening during transit.
