Product Identity

Partners Brand M663K Corrugated Mailers are kraft-coloured shipping containers sold in bundles of fifty. They serve small businesses and home sellers who need rigid, flat-packed mailers for posting flat or shallow items.

Sustained Load Behaviour

The corrugated construction keeps its shape when stacked in outbound cages or loaded onto conveyor belts during peak dispatch periods. Flutes resist crushing so contents stay protected through multiple handling points without the mailer collapsing.

Thermals Noise and Power

As passive packaging the mailers generate no heat, draw no power and produce no sound. The kraft material remains stable across normal warehouse temperatures and does not degrade under typical indoor storage conditions.

Questions about this item

How much space does the 663 model take up when stored flat?

Each mailer arrives flat and measures 6 x 6 x 3 inches, so a bundle of 50 stacks to roughly three inches high and fits on a standard shelf.

What tape or sealant do I need to close these mailers securely?

The corrugated kraft flaps seal with any pressure-sensitive packing tape, water-activated tape or staples; no special adhesive is required.

Will the 663 mailers protect items already packed in thinner poly bags?

Yes, the rigid corrugated walls add crush resistance around existing poly bags, keeping contents from bending during transit.
