When a rubber part is packaged, it is for the sole purpose
of transportation from the supplier to the user. Packaging usually causes some distortion
of the rubber part which, if used in a reasonable length of time, does not permanently
affect the part. However, when rubber parts are held in a distorted position for a
prolonged period of time, permanent set may cause permanent distortion and result in
unusable parts. Any product on which distortion may make the part unusable should be
specified and packaged by such methods as will prevent distortion. However, such methods
are sometimes costly and should not be specified unless absolutely necessary. When
distortion is a problem, the product should be removed from the container when received
and stored on shelves or in a manner to perserve usability. Packaging is a complex area
and should be given serious consideration. Special packaging problems should be considered
between purchaser and supplier.
