Increases the transport belt stack size by 1, up to 4. Only stack inserters, big mining drills and recyclers can create belt stacks.
Stack inserter research introduces a baseline stack size of 2, doubling the throughput compared to non-stacked belts. There are two levels of transport belt capacity research, each of which increases the stack size by 1.
Transport belt capacity 2 also increases the hand size of non-bulk and non-stack inserters by 1.

Belt throughput
Belt stack size allows more items to stack on a belt, therefore increasing maximum belt throughput.
