Collin blown film machine can be used for sample preparation for polymer functional testing, multi-layer film blow molding production, quality control for color distribution or defect detection, and production of small films or hoses in the food and medical fields. Collin's unique modular system design enables production line configurations with up to 13 layers of film, and is matched with extruder screw diameters. The blown film machine can be equipped with a melt pump or a volume/weight loss quantitative feeding system to ensure real-time monitoring of the wall thickness ratio of each layer of film.

Design of blown film die head for multi-layer film blow molding production, combined withThe stable polymer plasticization process of Collin extruder and the uniform distribution design of multi melt flow channels in the die head can ensure uniform thickness and good stability of each layer of the film. The 3-layer, 5-layer, and 7-layer blown film molds can be used to produce more complex packaging product films or functional films.

The blown film tower is equipped with thin film herringbone clamps of different materials(such as carbon fiber inserts, wood inserts, etc.), consistent with the concept of Collin modular design. A huge advantage of the blown film tower is that the height of the traction roller is adjustable. This makes it possible to adjust the cooling characteristics of different polymers separately. In addition, other detection or special processing functions can be added, such as thickness measurement, annealing treatment, corona treatment, film defect detection system, and film edge cutting treatment.

The blown film machine is mainly defined by the roller diameter of each traction roller, and the corresponding roller diameter is200 mm、400 mm、600 mm、800 mm、1000 Mm, etc., 400 Mm is the most commonly used model.
