The cost difference between blown film stone paper and cast stone paper involves multiple aspects, including raw materials, equipment investment, energy consumption, production process, and labor costs. The following is a detailed analysis of the cost difference between these two production methods.
1. Raw material costs
The main raw materials for both methods are stone powder and polymer, but in the mixing and preparation process, more additives may be required to improve the fluidity and formability of the film when casting stone paper. Therefore, although the basic raw materials are similar, the specific amount of additives used will have an impact on the overall cost, resulting in different raw material costs for the two.
2. Equipment investment
The blown film production line needs to be equipped with equipment such as extruders, blown film heads, cooling systems, and winding devices. Due to the need to regulate the gas during the blown film process to form a film, which usually requires a high level of equipment technology, the investment cost of the equipment is relatively high. The casting equipment is relatively simple, requiring equipment such as extruders, casting molds, and roller cooling systems. Although high-level automation is also required, the overall investment is relatively low.
3. Energy consumption differences
The blown film process requires gas blowing of the molten resin, resulting in relatively high energy consumption. The casting process mainly relies on hot rollers and roller cooling, with relatively low energy consumption. Especially in large-scale production, subtle differences in energy consumption can accumulate a significant impact on the total cost.
4. Production efficiency
Under normal circumstances, blown film technology can achieve high production efficiency, especially in terms of film thickness and width uniformity, which can increase production volume and reduce unit product costs. The film thickness produced by the casting process needs to be adjusted and controlled multiple times, which may result in lower production efficiency and increase the cost per unit product.
5. Labor costs
Blowing film usually requires workers with higher technical skills in both equipment operation and maintenance, resulting in an increase in labor costs. The production process of cast stone paper is relatively simple and has lower labor costs.
6. Product market positioning
The market positioning of the final product will also affect the evaluation of production costs. If blown film stone paper is positioned as a high-end product, it can usually be priced higher to indirectly offset its higher production costs. Cast stone paper is more commonly used for general packaging or daily necessities, and its market competition is fierce with high price sensitivity.
summary
Overall, there are significant differences in production costs between blown film stone paper and cast stone paper, mainly reflected in equipment investment, energy consumption, labor costs, and production efficiency. Although blown film technology has advantages in production efficiency, its equipment and energy consumption costs are relatively high. Although the equipment investment for the casting process is relatively low, in some cases, the cost per unit product may increase due to the relationship between production efficiency and labor costs. Therefore, when choosing production processes, enterprises need to comprehensively consider market demand, product characteristics, and their own production capabilities.
