Not necessarily. Truckers will often pick up entire new loads and chain deliveries depending on whether they're last mile/long haul/commodity/or specialized equipment haulers.
So your packaging job would likely just be another blip on another trucker's route. But it would increase the need for more truckers since you're essentially (worst-case) doubling the number of deliveries to be done per transaction.
The producer externalized this extra truck cost to taxpayers (garbage trucks, landfills and environment aka dumping/littering/pollution). If the consumers see a lot of increased costs for plastic wrapped bananas with the seller having to deal with the waste; that is actually the point and the incentive for the producer to minimize waste.
