   what is the difference between the micro corrugations ,E ,F ,N flute . 

    Although there is not a significant amount of difference between the three flutes, F-Flute is half as thick as the E-flute and the N-flute being even thinner. N-flute provides almost twice as many flutes per lineal foot than the E flute.

Therefore, F and N-type micro-flute are getting an increasing interest in the Packaging industry, which is very concerned about its carbon footprint (less fiber consumption, lighter packaging, smaller volume of the packaged good for warehousing and transportation) and still wants adequate protection for the product. This is especially true for goods requiring both particular care and elegant packaging (fine foods).

In the food and beverage, cosmetics and pharma industries, F and N-type micro-flute are becoming a material of choice because of their enhanced printability and folding capabilities and still offering a more rigid packaging than E-flute. Since F and N type cardboards have a much larger number of flutes per foot, they allow more accurate folding operations.
