Cardboard Envelopes

Printed Cardboard Envelopes

Custom printed cardboard envelopes not only protect your items but also make every delivery feel professional and thoughtful, giving you peace of mind and leaving a lasting impression on recipients. Made from durable 380gsm SBS paperboard, they are lightweight yet strong, with a rigid structure that helps prevent bending or creasing while protecting contents during transit.

Each envelope features a strong adhesive seal and an easy-open tear strip for secure and convenient delivery. Their slim, rigid design can also speed up packing compared with boxes by reducing the need for void fill or extra tape. Envelopes are offered in quantities from 25 up to 1,000.

With a high-quality print surface and the option for matt, gloss or soft-touch lamination, these envelopes offer excellent customisation to showcase your branding and create a professional unboxing experience.

These envelopes help your business deliver a polished impression while providing practical, protective mailing solutions. Their lightweight, postal-friendly format can also help reduce damage, returns and shipping bulk compared with traditional boxes.

• A4 Portrait (H 31.5 × W 22 cm) – Designed for documents, certificates and print proofs.
