Cardboard Envelopes FAQs

What is a cardboard envelope?

A cardboard envelope, also known as a stiff or rigid envelope, is a mailing or packaging solution made entirely or predominantly from cardboard. These envelopes are designed to provide a sturdy and protective enclosure for documents, photographs, brochures, promotional materials, or other items that need to be sent through the mail or courier services.

Cardboard envelopes typically have a stiff and durable construction, which helps prevent the contents from bending, creasing, or becoming damaged during transit. They are available in various sizes, including standard sizes like A4, A5, and more, making them suitable for different document dimensions.

These envelopes often feature a secure closure mechanism, such as a peel-and-seal strip or a flap that tucks into a slot, to keep the contents securely in place.

Cardboard envelopes can be plain, allowing for customisation with labels, stamps, or additional branding elements. Pre-printed designs or branding can also be applied for a professional and polished appearance. Overall, cardboard envelopes are a practical and eco-friendly option for businesses and individuals looking to mail important documents or promotional materials with confidence that they will arrive at their destination in excellent condition.
