The Zoro Select M744 is a white corrugated cardboard mailer with inside dimensions of 7 by 4 by 4 inches. Each box uses single-wall B-flute construction rated at ECT-32 and supports a maximum load of 65 lb. The pack contains 50 flat mailers made from 100 percent post-consumer recyclable material.

Questions about this item

Will the corrugated cardboard degrade if I store the mailers in a humid warehouse?

The single-wall B-flute construction uses 100 percent post-consumer recyclable cardboard; prolonged moisture exposure can weaken the flutes and reduce the 65 lb load rating, so keep the flat pack dry until assembly.

At what weight does the ECT-32-B rating stop protecting the contents during a long transit?

The edge-crush test rating of 32 supports a maximum load of 65 lb; exceeding that limit risks box failure under sustained stacking pressure.

How much heat builds up inside a sealed 7x4x4 mailer left in a delivery truck all day?

Corrugated cardboard provides modest insulation; internal temperature will track ambient conditions, so avoid shipping heat-sensitive items without additional thermal lining.
