{{About/Space age}}<br />
'''Increases''' the [[transport belt]] vertical stack size by 1, up to 4. Only [[stack inserter]]s, [[big mining drill]]s and [[recycler]]s can create belt stacks. All inserters can pick individual items from stacks. Items stacked in this way do not become single "bundled" items. These stacks exist only on belts.<br />
<br />
The prerequisite [[Stack inserter (research)]] increases stack size on belts from 1 to 2. Transport belt capacity research increases the stack size on belts to 3 and then 4.<br />

== Belt throughput ==<br />
Belt stack size allows more items to stack on a belt, therefore increasing maximum belt throughput.<br />
