The plastic bar productivity research increases the productivity of machines that craft plastic bars by 10% (flat) per level.
The cost formula is 1.5L * 1000 where L = current level.
Note that the 300% productivity limit does apply to this technology. You can research past level 30, but it will have no practical effect.
