The three-layer co extrusion blown film machine is a powerful and efficient packaging equipment widely used in the packaging industry. Its multi-layer extrusion technology and advanced control system make it have great market potential. In the future, with the development of the packaging industry and the increasing demand for packaging quality, three-layer co extrusion blow molding machines will be widely used and promoted.

The three-layer co extrusion blown film machine has higher production stability. Due to the three extrusion mechanisms, the parameters of each extruder can be adjusted according to product requirements, such as extrusion speed, extrusion pressure, etc., in order to achieve a more stable production process. Meanwhile, the three-layer co extrusion blown film machine can also be equipped with an automatic control system to monitor and adjust the operating status of each extruder, ensuring the stability and consistency of the production process.

What are the different models of three-layer co extrusion blown film machines to choose from?

SJM three-layer co extrusion blown film machine. The SJM model is one of the commonly used three-layer co extrusion blown film machine models in the current market. It adopts an advanced high-precision closed-loop control system in China, which has functions such as automatic constant temperature control and automatic tension control, and can achieve high-speed production and high-quality thin films. This model is mainly suitable for producing plastic packaging film, agricultural land film, protective film, etc.

SJ55/110/55 three-layer co extrusion blown film machine. The SJ55/110/55 model is a three-layer co extrusion blown film machine with double head extrusion. It uses two extrusion units to simultaneously extrude screws of different materials, and through multi-layer lamination within the die head, produces a three-layer composite film. This model has the characteristics of high production efficiency, low energy consumption, and low noise, and is suitable for factories that require large production capacity.

SJW three-layer co extrusion blown film machine. The SJW model is a high-speed three-layer co extrusion blown film machine. It adopts advanced COEX co extrusion technology, which can achieve high-speed production of three-layer composite films. This model has a high-precision temperature control system, automatic tension control system, and automatic mesh changing system, which can provide users with high-quality film products.

The working principle of the three-layer co extrusion blown film machine is to add three different plastic materials to three extrusion units, each material is plasticized through its own screw, and then the three-layer materials are extruded into three-layer thin films through the extrusion nozzle. The structure of the extrusion nozzle allows the three layers of film to be bonded together, forming an integrated film. The extruded film is cooled and stretched through cooling and traction rollers, and the finished product is rolled up and cut by a winding machine.

The three-layer co extrusion blown film machine has many characteristics and advantages. It can produce multi-layer thin films, which have great advantages in physical properties and appearance effects. Multilayer films can improve the impact resistance, penetration resistance, and heat resistance of products, while also increasing the flexibility and transparency of the film, making the product more competitive. Secondly, the production efficiency of the three-layer co extrusion blown film machine is high, which can meet the needs of large-scale production. The speed and temperature of the extruder can be precisely controlled and adjusted as needed to improve the stability and efficiency of the production line.
