Equipment procurement decisions should not only consider the initial investment but also focus on the total life cycle cost. Two-fold machines have the lowest initial investment, but their limited functionality and lower efficiency must be taken into account. The total life cycle cost includes acquisition costs, installation and commissioning expenses, operator labor costs, energy consumption, maintenance expenses, spare parts consumption, downtime losses, and final disposal costs. Although the individual maintenance cost of a two-fold machine is low, their efficiency limitations may necessitate multiple machines to meet production capacity demands, thereby increasing overall operational costs.

The initial investment for three-fold machines is 30%–50% higher than that of two-fold machines, but they typically deliver better life cycle value. Higher production efficiency reduces the need for multiple machines; better quality consistency lowers scrap losses; and broader product adaptability extends the effective service life of the equipment. The maintenance cost for three-fold machines is slightly higher, but advanced predictive maintenance systems can reduce unexpected failures and downtime losses. Overall, the total cost of ownership for three-fold machines over 3–5 years is generally lower than that of multiple two-fold machines with equivalent production capacity.

As high-end equipment, four-fold machines require the highest initial investment, but their life cycle value is reflected in multiple dimensions: the brand premium they bring to high-end products, ultra-high production efficiency, exceptional quality performance, long-term precision stability, and the competitive advantage gained from technological leadership. Maintenance for four-fold machines requires more specialized technical support, but modular design and remote diagnostic technologies reduce maintenance difficulty and costs. For suitable applications, the return on investment for four-fold machines over long-term operations may be the highest.

Investment decisions must align with the specific circumstances of the enterprise: product positioning determines packaging quality requirements; production capacity demands determine the quantity and configuration of equipment; technical capabilities determine equipment availability; and financial strategies determine capital costs and return expectations. Quantitative analysis tools, such as net present value analysis, internal rate of return calculations, and payback period evaluations, combined with qualitative factors like strategic alignment, technological development trends, and supply chain risks, provide a comprehensive basis for investment decision-making.
