12 x 15 1/2 Envelopes

This collection includes open-end and first-class envelope styles in white paper, brown kraft, Tyvek, and poly. A self-sealing flap simplifies preparation when reports or print materials need to be distributed efficiently. Tyvek shipping envelopes give offices and schools a straightforward way to organize papers that need to stay together through filing or distribution.

When documents need more durability in transit or storage, Tyvek adds tear resistance without extra bulk. The open-end layout keeps large poly and Tyvek documents easier to load for mailing, storage, or distribution. Poly and Tyvek constructions both add extra durability compared with standard paper stock. Large poly mailers offer different levels of access and durability, allowing the envelope to match the way documents are filed, mailed, or handled.

Large poly mailers suit heavier-duty filing and mailing needs across offices, schools, and studios. Tyvek shipping envelopes add tear resistance for reports and project files that travel or get handled often. The right Tyvek shipping envelopes can reduce extra handling by keeping flat documents organized through filing, transport, and delivery.
