Can you please let me know as how to calculate the take up factor of flute? We are producing B flute. I know the pitch formula but a bit confused calculating the take up factory.

Please help.

I will be glad to determine the individual weights of the two boxes. To accurately determine the full size of the sheets from which the RSCs are made we need to have the height of the box. If you can provide those dimension we can calculate the weight of the two boxes.

]]>can you help me out

today i am calculate the box weight for bottom box and top box weight.

bottom size is length is 720 mm width is 930 mm

top size is length 555 mm and width is 1200 mm

paper gsm is kraft is 130 gsm and flute B 125 gsm and text liner is 127 gsm

i am using formula is

kraft paper wt Sheet length * width*gsm= wt /1000000000

Flute B Sheet length * width*gsm *1.4= wt /1000000000

test liner Sheet length * width*gsm= wt /1000000000

finally i got one box weight

i am using this formula sir

please help me out

]]>This calculator is designed to calculate in imperial measurements (pounds per thousand square feet) instead of grams per square meter. This is where your confusion, or incorrect answer, is coming from. Also, our take ups are hard coded constants that are considered fairly standard in North America. They are represented in pounds per thousand square feet of fluted medium. As you change the flute type in the calculator, the take up will automatically change.

Basis Weights:

Basis weights are in pounds/msf (thousand square feet). It looks like you’re entering gm2. So that will certainly not give you the answer you’re looking for.

RSC Size:

The calculator only uses the flat dimensions (length and width) not erected “3D” dimensions L, W, H. Folded means two panels of the RSC has been folded and glued… but not erected… so it is still flat.

So if you want to use this calculator to calculate weight in grams you must first convert your basis weights from g/m2 to lbs/msf . Then, convert the results from pounds (or ounces) to grams (or kilograms).

]]>Thanks for the RSC weight Calulator for single wall & double wall.

But i dont know why the weight calculated is coming wrong when i enter the following:-

Size of the box is (Inches) Length15.27XWidth10.15XHeight10.31

Liner 1- 120gsm

medium1- 120gsm

liner 2- 120gsm

medium 2- 120gsm

liner 3- 120gsm

Take off is 1.35

RSC width inches- 10.15

RSC length inches-15.27 (THERE IS NO OPTION ON HEIGHT)

Unfolded

Optional dimensions

Slot depth inches- 5

Slot width inches- 14.90

Glue tab width inches-1.50

Glue tab length inches-10

The weight of box is coming wrong.

Also how can i adjust the take off factor.

Please guide with all figures & let me know if i have entered all figures correctly or not.

Awaiting reply

Thanks
