Double chamber tea bag machine factory prices vary wildly, from basic models around $1,000 - $6,000+ USD for simpler, slower machines (often from China) to advanced, high-speed, fully automated systems costing $20,000 - $100,000+ USD, depending on speed, features (string/tag, ultrasonic sealing, outer envelope), brand, and automation level (semi vs. full). Expect basic models to be at the lower end ($1k-$10k) and high-capacity, integrated lines to be much higher ($50k-$300k+).
