Speed Efficiency: Efficiency is a ratio of output over input, but in packaging production, this definition has many subtle variations. For this discussion, efficiency is used to describe a station’s or a packaging line’s actual operating time over the available time. The speed hierarchy would be as follows: 1. Design speed 2. Capacity 3. Run speed 4. Output rateSpeed Efficiency: Efficiency is a ratio of output over input, but in packaging production, this definition has many subtle variations.
