In the production of stone paper, the casting process and blown film process are two common production methods. They each have different characteristics and applicable scenarios, and choosing the appropriate process is crucial for improving product quality, reducing production costs, and meeting market demand. The following is a detailed comparison and selection suggestion for the two processes of production line for stone paper.
1. Casting process
advantage:
Thickness uniformity: The casting process ensures uniform thickness of the entire film material by pressing the molten polymer (resin part of stone paper) into a thin film. This is suitable for manufacturing stone paper products with relatively consistent thickness.
Surface smoothness: The casting process can provide a high smoothness surface, suitable for applications that require high printing quality and aesthetic appearance, such as packaging, advertising materials, etc.
Performance flexibility: This process can achieve precise control of product performance by adjusting the gap between the casting blades, cooling methods, etc., to meet the needs of different applications.
Disadvantages:
Slow production speed: Compared with blown film technology, the production speed of cast film technology is usually lower, which may appear insufficient under high production demand.
High equipment investment: The investment in casting equipment is relatively high, especially when high precision and efficiency are required.
Fast production speed: The blown film process can produce a large amount of thin films in a short period of time, making it suitable for large-scale production. Therefore, it has advantages in meeting large-scale market demand.
Strong adaptability: By adjusting equipment parameters, the blown film process can produce thin films of different thicknesses and widths, with good flexibility.
Lower equipment investment: Compared to the casting process, blown film equipment usually has lower investment, maintenance costs, and operational complexity.
Disadvantages:
Uneven thickness: During the blown film process, due to factors such as inflation, the thickness of the film may not be very uniform, which may affect the quality of some high-end products.
Surface treatment difficulty: Blown film is usually not as smooth as the casting process in terms of surface smoothness and printing adaptability, so it may not be suitable for certain applications that require high surface quality.
Casting process is suitable: If your target market is mainly focused on high-quality, high smoothness products such as high-end packaging, paper products, or artistic printing, casting process may be more ideal.
The blown film process is suitable: If the market demand is high and production speed is the primary consideration, and the requirement for thickness uniformity is not high, the blown film process will be a more suitable choice.
Economic considerations:
When the budget is limited and the product demand is stable without requiring particularly high surface quality, choosing blown film technology can reduce initial investment and operating costs.
If the product is positioned in the high-end market, although the initial investment is high, the casting process can significantly improve the competitiveness of the product, which may bring better economic benefits in the long run.

2. Film blowing process
