Three layer and Five Layer plant

 In Modern time of manufacturing of BOPP film,

Mostly 3 Layer and 5 Layer Extruded layer Films used.

Lets understand one by one and also difference between both.

1) 3 Layer extruded film -

in three layer extruded film, there are total three layer. Main layer is called core layer which is thick, extruded by main extruder, and bounded by two skin layer both side of it to enhance its property. Lets understand by picture given below

2) Five Layer extruded Film Plant-

In Five layer extruded film, there are total five layer. Main layer is called core layer which is thick, extruded by main extruder, and bounded by two skin layer extreme outside of it and two intermediate layers adjacent to it both side to enhance its property. Lets understand by picture given below
