Partners Brand B861 Poly Mailers 14 1/2 x 19

These white polyethylene mailers measure 14 1/2 by 19 inches and come in a pack of 500. They are designed for shipping and mailing operations that need lightweight, moisture-resistant packaging. The self-seal closure speeds up packing workflows. Buyers who need padded protection or larger dimensions should consider other options.

Thermals Noise Power

As passive shipping supplies, these mailers generate no heat, noise, or power draw during use. Their polyethylene construction resists punctures, water, and tears to protect contents from environmental moisture. The tear strip allows recipients to open packages cleanly without tools. No electrical or thermal management is required.

Build Quality Connectors

Each mailer features a white outer surface with a silver inner lining that accepts labels, stamps, and ink adhesion. The self-seal flap creates a tamper-evident closure once pressed shut. California Proposition 65 warnings apply due to chemicals known to cause cancer and reproductive harm. The flat, flexible design stores compactly and mounts easily on packing stations.

Questions about this item

How do I seal the Partners Brand B861 mailer and what step is often missed?

Peel the protective liner from the self-seal adhesive strip, press firmly across the full width, and ensure the silver inner lining is clean so the bond holds during transit.

Will the polyethylene material degrade or need replacement after storage?

The poly mailers resist moisture and punctures, but prolonged heat or direct sunlight can weaken the adhesive and embrittle the film; store flat in a cool, dry area and use within a reasonable period.

At what point does the 14 1/2 x 19 inch size become the limiting factor for bulky items?

The mailer expands slightly but cannot accommodate rigid or thick objects that exceed the flat dimensions; overstuffing stresses the self-seal and tear strip, risking failure during handling.
