Snap Packs

Snap packs are pressure-sealed mailers that resemble official documents and encourage higher open rates. They do not require envelopes and are opened by tearing along perforated edges. The sealed design keeps contents hidden until opened, making snap packs ideal for sensitive or important documents such as contracts, forms, or notices.
