Hey,
I need guidance about grammage of corrugated box, cardboards and plastic foil
-How to calculate?
-Used same method for all three or different method for each?
Currently, I'm try to solve this problem through this method: GSM =gm/m2
-cut sample 1 inch square
-then weight this sample cut sample
- now using formula
GSM=weight/ 0.000645m2
I'm using this method for all type of packaging. But every time reading are vary...
Kindly, packaging expert guide me for right method..
Thank you..

postedyour formula is true.
use a precision scale (analytical )
use mm not inch
cut samples 50mmx50mm
use 5 samples then take them average and use it.
be careful.
Good luck :blush:
