Packaging systems are generally not known for consuming significant amounts of energy compared to other categories such as HVAC systems, compressed air, and motors, pumps, and fans. While packaging processes are essential in many industries, they tend to be more focused on materials and operations that do not require extensive energy input relative to the energy demands of these other systems.

HVAC systems often require large amounts of energy for heating, cooling, and ventilation, making them a significant category in overall industry energy consumption. Similarly, compressed air systems are known for their inefficiencies and can be major energy consumers due to leakage and the energy intensity of producing compressed air. Motors, pumps, and fans also account for a significant portion of energy use in industrial operations, as they are essential for various mechanical processes.

In comparison, while packaging systems are important for production and logistics, their energy demands are typically lower and more variable depending on specific processes and materials used. Thus, this context highlights why packaging systems are categorized differently regarding energy consumption.
