The water containing granulation series is suitable for water containing film materials, woven bags, ton bags, airbag fabrics, and cup materials. The screw barrel adopts a special feeding design with an upper opening, which allows for fast feeding, smooth drainage, and high output. Commonly used second-order and third-order formulas. The commonly used specifications for screw barrels are Φ 120- Φ 280, with a length to diameter ratio of 15-26
