The three-layer co extrusion blown film machine is an efficient, energy-saving, and environmentally friendly plastic film production equipment with broad application prospects and market demand. With the continuous improvement of people's requirements for packaging material performance and environmental protection, three-layer co extrusion blown film machines will be widely used and developed in the future. In the field of agricultural coverage, three-layer co extrusion blown film machines can produce UV resistant and wear-resistant films, which are used for fruit tree protection, greenhouse covering, etc.

The three-layer co extrusion blown film machine is widely used in the food packaging industry, which can produce various shapes and functions of food packaging bags, cling film, frozen bags and other products. At the same time, the device is also used in the medical and health field, and can produce products such as medical fresh-keeping bags and disposable surgical packaging films. In addition, the three-layer co extrusion blown film machine can also produce insulation films, thermal insulation films and other products in the field of building materials, with broad market prospects and application potential.

What is the production efficiency of the three-layer co extrusion blown film machine?

The production speed of the three-layer co extrusion blown film machine is fast. Driven by an extruder, molten plastic is extruded through a die, and with the assistance of a cooling roller, a thin film is formed. Due to the use of multiple extruders in the three-layer co extrusion blown film machine, multiple films can be produced simultaneously, which can produce a large amount of films in a unit time and improve production efficiency.

Secondly, the operation of the three-layer co extrusion blown film machine is simple, and the operator only needs to control the operation of the extruder, die head, and auxiliary equipment to complete the production process. The high degree of machine automation ensures stable and reliable production processes, reduces opportunities for human intervention, and improves production efficiency.

In addition, the three-layer co extrusion blown film machine has high film quality, good tensile and heat resistance, and can meet the needs of different fields. The surface of the produced film is smooth and uniform, without obvious bubbles or defects, which improves the quality and market competitiveness of the product.

The working principle of the three-layer co extrusion blown film machine is to heat and melt different types of plastic particles through the extruder, extrude them through the die and form a film, cool them through the air ring, stretch them through the stretching system, and finally roll the film up through the winding system. A three-layer co extrusion blown film machine usually consists of three parts: an inner layer, a middle layer, and an outer layer. The inner and outer layers are usually made of plastic particles of different colors, while the middle layer is usually made of transparent material. This produces films that are more aesthetically pleasing and have better performance.

The operation process of a three-layer co extrusion blown film machine generally includes raw material preparation, extrusion production, extrusion adjustment, winding, and cutting. In the raw material preparation stage, operators need to proportionally place plastic particles of various colors or functions into the three extrusion mechanisms of the machine, and adjust the temperature and pressure of the extrusion mechanisms to ensure that the plastic particles can melt smoothly and mix evenly. During the extrusion production process, operators need to monitor temperature and pressure changes and adjust the parameters of the extrusion mechanism in a timely manner to ensure that the quality and thickness of the film meet the requirements.
