Advantages of three layer co-extrusion blown film machine and its main use
- Jan 31, 2019 -

In order to meet the special functions of plastic film packaging materials in the production process, a variety of characteristic materials were blown and co-extruded to form a multifunctional plastic film, and a multi-layer co-extrusion film blowing machine was developed. The three layer co-extrusion blown film machine  is one of the multi-layer co-extrusion blown film machines, the purpose is to take advantage of a variety of materials, to avoid some of the shortcomings of a single material or a single layer blown film machine.
The three layer co-extrusion blown film machine  combines the characteristics of the high hardness of the PP material with the high brightness of the PE material to produce a film combining the two characteristics. In addition to the three-layer co-extrusion blown film machine, there are five-layer co-extrusion blown film machine, seven-layer co-extrusion blown film machine, etc., which belong to such products.
Three-layer co-extrusion blown film machine adopts new high-efficiency low-energy extrusion unit, IBC bubble internal cooling system, ±360° horizontal traction system, photoelectric automatic correcting device, automatic winding and film tension control, computer screen automatic Advanced technologies such as control systems.
Compared with similar equipment, it has the advantages of higher output, good plasticization, low energy consumption and easy operation, which completely solves the problems of film ruffle and winding size. The produced film has high transparency, puncture resistance, high toughness, good low temperature hot cut property, good composite fastness and anti-curling property. The film is widely used for light and heavy packaging because of its good barrier property, preservation, moisture resistance, frost resistance, oxygen barrier and oil resistance.
