## 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)

To calculate BOPP film weight, multiply the mil gauge by the length and width, then multiply by 0.000004.

## 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
