12 x 18 Envelopes

This broad size collection combines booklet, expansion, plastic, Tyvek, and X-ray envelope and mailer options across materials such as kraft, Tyvek, and plastic. Closure choices include button-and-string and hook & loop. The variety supports routine document mailing, reusable filing, protective shipping, and thicker or more specialized contents for documents and materials that require the same envelope size.

Button-and-string closures provide repeated access for filing and document storage. Hook & loop construction makes larger healthcare and document files convenient to reopen during repeated review. Tyvek is useful for medical records and documents that need a lightweight material with greater tear resistance. The mix of Tyvek, plastic, and specialty storage options supports healthcare, filing, and document workflows that need different durability levels.

X-Ray storage envelopes are designed for medical imaging film, diagnostic records, and other sensitive materials that require organized, protective storage. Clinics, hospitals, imaging centers, and healthcare administrative offices rely on this envelope style for archival filing and secure transport of patient records. The reusable construction supports repeated access while keeping film and documents protected between uses.
