Our custom cylindrical diploma mailer is a protective and professional paper tube container for rolled certificates and documents. The tube is made from rigid paperboard and designed to keep diplomas, certificates, scrolls, posters, and artwork safe during mailing, hand delivery, or ceremonial presentation.
The sample shown features a long printed paper tube with a removable cap and full-wrap custom artwork. This style is suitable for educational institutions, universities, tourism brands, cultural events, award programs, and corporate certificate campaigns. The tube body can be printed with logos, school names, event titles, QR codes, instructions, mailing labels, or decorative artwork.
Compared with envelopes or flat mailers, a cylindrical diploma mailer provides better protection for rolled documents and creates a more premium presentation. It can also be produced with recycled paperboard, FSC paper, soy-based ink, and water-based coating for brands looking for more eco-conscious document packaging.
