Pet Film Roll Weight Calculator
To calculate the weight of a PET film roll, you will need to know the following information:
- Width of the roll in inches
- Length of the roll in feet
- Thickness of the film in mils (1 mil = 0.001 inches)
- Specific gravity (density) of the PET material
Once you have this information, you can use the following formula to calculate the weight of the roll:
Roll Weight (lbs) = [Width (in) x Length (ft) x Thickness (mils) / 1000] x Specific Gravity
For example, if you have a PET film roll that is 12 inches wide, 500 feet long, and has a thickness of 2 mils, and the specific gravity of the PET material is 1.4, the calculation would be as follows:
Roll Weight (lbs) = [12 x 500 x 2 / 1000] x 1.4 = 42 lbs
So, the weight of the PET film roll in this example is 42 pounds.

FAQ
How do you calculate the weight of a plastic film roll?
A: To calculate the weight of a plastic film roll, you need to know its length, width, thickness, and density. Multiply the length by the width by the thickness to get the volume in cubic inches. Then multiply the volume by the density of the film to get the weight in pounds.
How do you calculate the weight of a paper roll?
A: To calculate the weight of a paper roll, you need to know its length, width, thickness, and basis weight (weight per unit area). Multiply the length by the width by the thickness to get the volume in cubic inches. Then multiply the volume by the basis weight to get the weight in pounds.
What is the weight of a film roll?
A: The weight of a film roll can vary depending on the dimensions and type of film. Generally, plastic film rolls can range from a few pounds to several hundred pounds.
How do you calculate the weight of a stretch film roll?
A: To calculate the weight of a stretch film roll, you need to know its length, width, thickness, and weight per thousand feet (WPM). Multiply the length by the width by the thickness to get the volume in cubic inches. Then divide the volume by 1,728 (the number of cubic inches in a cubic foot) and multiply it by the WPM to get the weight in pounds.
How do you calculate film weight?
A: To calculate the weight of a film, you need to know its length, width, thickness, and density. Multiply the length by the width by the thickness to get the volume in cubic inches. Then multiply the volume by the density of the film to get the weight in pounds.
How much does a roll of stretch wrap weigh?
A: The weight of a roll of stretch wrap can vary depending on its dimensions and thickness. Generally, a standard roll of stretch wrap can weigh anywhere from a few pounds to around 20 pounds.
