Three screw co-extrusion film blowing machine

A three-layer co-extrusion film blowing machine is a type of machine used in the package business to produce multilayer films with specific characteristics. These machines are used to create films with a combination of different materials, such as polyethylene (PE), polypropylene (PP), and other polymers.

The film blowing extruder consists of three extruders, each of which melts and extrudes a different polymer through a separate die, producing three distinct layers of film. These layers are combined into a single film as they pass through a co-extrusion die, which fuses the layers together into a cohesive film.

The blown film machine is used to produce films with specific properties such as high strength, excellent barrier properties, improved heat resistance, and good printability. These properties are achieved by combining different materials with different properties in specific layers. A film produced with a three-layer co-extrusion machine may have a layer of PE on the outside for its excellent sealing properties, a layer of PP in the middle for its rigidity, and another layer of PE on the inside for its heat-sealability. This combination of materials and layers results in a film that has improved properties and is suitable for packaging products such as food, pharmaceuticals, and chemicals.

Usually we design this machine with advanced features such as automatic thickness measure system, automatic winding, which ensure that the produced films are of consistent quality.

Our plastic film blowing machine is easy to operate, energy-efficient, and capable of producing films with high optical clarity and mechanical strength. It is able to handle a wide range of plastic materials, including low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE).

With a reliable PE film extruder , our machine can meet customers’ production goals with ease and produce high-quality plastic films that meet their customers' expectations.
