2.3   Flexibility/Flexural Strength 

Application

When an item is ready for mailing (i.e. its contents inserted, and the flap sealed), ensure it meets these requirements.


Short and Long

Ensure that items have sufficient flexibility and strength, so that they:

Sag no more than 10 mm when freely supported between two level supports that are located 10 mm from their left and right edges.
Can be bent around a 140 mm radius without being damaged.

Single CD or DVD mailers typically meet this requirement.


Oversize

Ensure that these items have sufficient strength to remain horizontal when you hold the edge of an item in one hand.

These items do not have to bend. Package these items in either flexible or rigid materials, such as paperboard or corrugated cardboard.
