Questions about this item

Will the B-flute corrugate walls need reinforcing after repeated packing cycles?

The single-wall B-flute construction is rated at 200# board test and 1/8 in wall thickness for standard shipping durability.

At what load does the 200# board test become the limiting factor during continuous stacking?

The 200# board-test rating defines the maximum stacking strength before the corrugate begins to deform under sustained weight.

How much heat builds up inside a sealed 18x12x4 in mailer left in a delivery vehicle all day?

The white corrugate reflects sunlight, reducing internal temperature rise compared with darker mailers during extended transit.
