Black Open End Envelopes

Short-side loading suits forms, reports, photographs, and presentations with JAM Paper black open-end envelopes. Sizes include coin, 6 x 9, 9 x 12, and 10 x 13 inch document envelopes. Smooth midnight black and black linen papers create distinct finishes, while clasps and peel & seal strips address reusable or one-time closure needs. Open-end styles handle business mail, filing, school materials, event documents, portfolios, and records.

Closure selection lets black document envelopes match reusable storage or one-time mailing needs. Metal clasps permit repeated access to forms, files, and project papers, while peel & seal options close securely without tape or moisture. Smooth paper creates a clean finish and linen adds texture. A window style can display selected information. The open-end construction handles client files, certificates, reports, photographs, and office routing.

Multiple sizes reduce folding while keeping inserts from shifting. The 6 x 9 and 9 x 12 inch options handle smaller packets and letter-size papers, while the largest document style accommodates broader contents. Open-end construction allows direct loading, and dark paper gives files a polished appearance. Reports, photographs, certificates, presentations, office records, and client materials remain organized in the open-end design.
