In combination with Space Exploration, you can now use Advanced Assembly Machines in a feedback loop to create new packed cargo rocket sections out of thin air. Setup is one machine taking from a passive provider chest a packed cargo rocket section and unpacking it. Next, the machine outputs the unpacked sections directly into another machine that is set to pack them back up. The machine packing them back up puts its result into the same chest.
Starting the process requires to supply just one packed section into the unpacking machine, and 5 unpacked sections into the packing machine. From then on, the 20% passive productivity will make more. slow at first, but eventually, you end up with a chest full of packed cargo rocket sections.
