What is the difference between ABA blown film machine and single layer blown film machine?

Blown film machines, also known as film extruders, are mainly used to produce plastic films and can produce film products of different thicknesses and structures. In this regard, ABA blown film machines and single-layer blown film machines are currently the most popular choices. So, what is the difference between ABA blown  film  machine and single layer blown film machine?

The main difference between the ABA blown film machine and the single-layer blown film machine lies in the structure of the extrusion head and the process changes during the film production process.

1. Extrusion structure

The extrusion head structure of the ABA blown film machine is composed of three layers. The middle layer usually uses ordinary raw materials, and the two side layers use high-quality raw materials. This structure gives the film greater strength and durability.

The extrusion head structure of the single-layer blown film machine has only one layer and uses a single type of raw material to make the film.

2. Material mixing

The three extrusion structures of the ABA blown film machine can mix different materials. For example, the outer layer (A) may be made of a different material than the inner layer (B). This results in films with desired properties, such as improved strength, elasticity or barrier properties.

Single layer blown film machines produce films from a single material, creating a uniform film with consistent performance.

3. Production and efficiency

The presence of three extruders in the ABA blown film machine enables higher production capacity compared to single layer blown film machines. Additionally, ABA machines can produce films with enhanced properties at a lower cost because they use different materials for their outer and inner layers, optimizing material usage.

4. Versatility

ABA blown film machines are widely used in film fields that require specific requirements such as high strength, puncture resistance or barrier properties. By mixing different materials in ABA machines, manufacturers can create films with unique properties to meet specific customer needs.

Single layer blown film machines are better suited for applications that do not require specific material properties, such as general purpose packaging films or bags.

Conclusion

Although there are significant differences between ABA blown film machines and single-layer blown film machines, the company's specific application needs still need to be fully considered when choosing which blown film machine to use. When making a selection, the company needs to comprehensively consider factors such as the characteristics, production costs, raw material supply, and market demand of the film products produced, to ensure that the final blown film machine selected can best meet the company's actual needs and is economically reasonable. .
