This is considered to be a better grade of rubber a still better grade called pale crepe rubber involves.
This concept can be pictured by imagining space time as a rubber sheet.
Rubber elasticity refers to a property of crosslinked rubber.
The balls on the rubber sheet bend the sheet around them somewhat as matter bends space time in its vicinity.
The 1940s theory predicts a linear relationship between the force and the amount of stretching.
While intuitively appealing however the rubber sheet picture has its limitations.
Smoked sheet is folded into large bales for shipment to the processor it has a characteristic dark brown color in some cases the sheets are dried in hot air rather than smokehouses and the term air dried sheet is used.
The jiggling is driven by heat the usual driver of molecular motion.

The theory assumes that as the rubber is stretched each crosslink remains stationary stuck to its local chunk of rubber even as the chains between crosslinks jiggle around.
It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length.
