One available machine in Big Pharma is the Drug Packer, which (at its un-upgraded level) allows you to combine two identical products into a box, which can then be sold as a single unit for twice the revenue. (Profits will suffer due to the added processing cost.)
However, this machine only has one input, and can only add one product to a box per day, meaning that its output is necessarily slowed to one box (of 2 products) every two days (or 1 product per day.)
Without the Packer, your stream of products can be shipped directly to the output port at a rate of 1/day - the same as when using the Packer.
It therefore seems that packing your products has no apparent benefit over simply shipping them in single units - in fact it may be worse because you're paying to pack them.
Is there an optimal method for using the Packer in a production line (specifically a method that will reduce my operating margin and/or accelerate my revenue growth)? Is there, perhaps, another machine that should be used in conjunction with the packer to achieve optimum efficiency?
