Double-Layer Blown Film Extrusion Machine

 

Machine Introduction:

Equipped with two extruders, the two-layer blown film machine can produce two-layer film with different materials/colors on each layer. The die-head design ensures good color separation on each layer.
Application: Agricultural film, mulch film, construction, detergent bags, heavy-duty bags, shopping bags, garment packaging, shrink film, consumer packaging, and many others.

 

1.It is used for blowing HDPE/LDPE,which has been widely used for producing compound film,agricultural covering film,and film for textile, clothing and other packing material.
2.Good quality screw & barrel, die head and air ring
3.Single winder or double winder
4.Main motor adopts frequency control of motor speed to improve the speed regulating stability of main motor and save power by 30%
5.The screw and material barrel adopt 38 CrMoAl which has been nitridized. The traction frame adopts lifting type. no matter what size the film is, it can achieve the best effect of cooling.

 

 

 

How does multilayer blown film extrusion work? What is the difference compared to the single-layer technology?

Multilayer blown film extrusion is a process for producing plastic films with multiple layers. The process involves extruding molten plastic through a circular die and then blowing it up into a tube shape using compressed air. The tube is then cooled and collapsed, resulting in a flat plastic film. The main difference between multilayer and single-layer blown film extrusion is the number of layers in the final product. In multilayer extrusion, multiple layers of different types of plastic are extruded simultaneously and then combined into a single film. This allows for the creation of films with unique properties, such as improved strength, flexibility, and barrier properties. In contrast, single-layer extrusion only produces a single layer of plastic.
