Flat mailers for high-volume shipping

These flat mailers measure 13 by 18 inches and arrive in a pack of 100. They suit businesses that dispatch large batches of documents, catalogues or flat merchandise. The white surface accepts handwritten addresses and printed labels cleanly.

Practical limits of a flat paper mailer

The paper construction protects contents from creasing but offers no cushioning for fragile items. It cannot accommodate thick or rigid objects that exceed the envelope's flexible depth. Moisture resistance is minimal, so contents needing weather protection require an inner sleeve.

Replaces smaller envelopes or poly bags

Switching from smaller formats eliminates the need to fold oversized sheets or use multiple packages for a single shipment. The jump is worth it when your typical contents exceed A4 dimensions or when consolidating several items into one mailer reduces handling time. It does not replace padded mailers for breakable goods.
