1. Starting stage
In the 1990s, some domestic equipment manufacturers developed domestic stretch film extruding machine lines with independent intellectual property rights. However, the domestically produced equipment in this period was mainly a small-scale production line of single-layer, regardless of the mechanical properties of the equipment or the production capacity. Compared to imported equipment.
2. Mature stage
Driven by the demand of the cast film market in the 21st century, domestic stretch film extruding machine has made great progress, and the international competitiveness of domestic casting equipment is increasing. Multi-layer stretch film production lines with a width of 2500mm and 3000mm have been mass-produced, and some technical indicators have reached the standards of similar foreign products. With the emergence of 5000mm high-precision ultra-wide multi-layer cast film production line, it marks that the domestic stretch film extruding machine has entered a mature stage of rapid development.
