BOPP Film Weight Formula
The following formula is used to calculate the BOPP Film Weight.
BOPP = g * .254 * L * W / 63,500
Variables:
- BOPP is the BOPP Film Weight (lbs)
- g is the mil gauge
- L is the roll length (ft)
- W is the roll width (in)
How to Calculate BOPP Film Weight?
The following two example problems outline the steps and information needed to calculate the BOPP Film Weight.
Example Problem #1
- First, determine the mil gauge.
- The mil gauge is calculated to be : 250.
- Next, determine the roll length (ft).
- The roll length (ft) is measured to be: 300.
- Next, determine the roll width (in).
- The roll width (in) is found to be: 20.
- Finally, calculate the BOPP Film Weight using the formula above:
BOPP = g * .254 * L * W / 63,500
The values provided above are inserted into the equation below and computed.
BOPP = 250 * .254 * 300 * 20 / 63,500 = 6.00 (lbs)
Example Problem #2
The variables required for this problem are provided below:
mil gauge = 100
roll length (ft) = 200
roll width (in) = 100
Test your knowledge and check your answer with the calculator.BOPP = g * .254 * L * W / 63,500 = (lbs)
