Utility Flat Mailers for High-Volume Shipping

Partners Brand Utility White Flat Mailers measure 13 1/2 by 11 inches and arrive in a 200-count pack. The white finish gives parcels a clean, professional look for daily dispatch. They suit offices, warehouses and online sellers who process large batches of documents or flat goods.

Consistent Performance Through Long Mail Runs

Each mailer maintains its shape and rigidity across the full 200-piece quantity, so the last envelope seals as cleanly as the first. The flat profile feeds smoothly through postage meters and conveyor sorters without jamming. Bulk packaging reduces reorder frequency during peak shipping periods.

Replaces Smaller Packs and Mixed-Size Stock

Switching from assorted smaller boxes or padded envelopes to this single 13 1/2 by 11 inch size streamlines packing stations and cuts inventory complexity. The jump is worth it when daily ship volume makes per-unit cost and restock time the primary constraints. Buyers needing padded protection or custom branding should look elsewhere.

Questions about this item

How much space do the 13 1/2 x 11 inch mailers take up when storing a full pack of 200?

A pack of 200 flat mailers measuring 13 1/2 by 11 inches stores flat and fits easily on a standard office shelf or in a shallow drawer.

Do I need any tape, labels or a scale before I can use these white flat mailers?

The mailers arrive ready to load; you only need your contents, a sealing method such as tape or labels, and a scale if you are calculating postage.

Will documents printed on older A4 or Letter paper fit flat inside the 13 1/2 x 11 inch envelope without folding?

Yes, both A4 and US Letter sheets are smaller than the 13 1/2 by 11 inch interior, so they slide in flat with no folding required.
