Partners Brand Deluxe Literature Mailers 13" x 13" x 3" White PK50

Partners Brand Deluxe Literature Mailers

These white mailers measure 13 x 13 x 3 inches and arrive in a pack of 50. They suit offices, publishers and direct-mail operations that need to ship flat literature, catalogues or documents without folding. The rigid construction keeps contents crisp through standard postal handling. Buyers who need padded protection for fragile items or larger boxes for bulky goods should look elsewhere.

Thermals noise and power draw

As passive packaging supplies, these mailers generate no heat, emit no sound and draw no electrical power. They require no cooling, fans or external energy source during storage or transit. Their performance is unaffected by ambient temperature within normal warehouse or office ranges. There are no active components to monitor or maintain.

Sustained load behaviour

Under continuous daily use the mailers retain their structural rigidity and dimensional stability. The flat stack of 50 units stores compactly and feeds cleanly into manual or automated packing lines. Repeated folding of the self-sealing flaps does not degrade the closure integrity over the course of the pack. Long-term storage in dry conditions leaves the white finish clean and ready for branding or labels.
