BINGOPLAS TECHNICAL BUYER GUIDE
Stretch film roll weight and length calculator formula.
Buyers often compare stretch film by roll weight, width, gauge and length, but quote sheets do not always use the same format. Use these formulas to estimate net film weight or roll length before reviewing a written specification.

CORE FORMULA
Estimate roll weight from width, gauge and length.
For standard polyethylene stretch film, the commonly used estimate is based on film width, nominal gauge, roll length and material density. This is useful for quote review, inventory planning and checking whether a roll label is reasonable.

EXAMPLE
18 inch, 80 gauge, 1,500 ft hand stretch film.
Apply the film factor
2,160,000 x 0.000002403 = approximately 5.19 lb of net film.
Confirm net versus gross
The core, carton and packaging are not part of net film weight, so confirm what the supplier label includes.
FREQUENTLY ASKED QUESTIONS
Stretch film roll weight questions.
How do I calculate stretch film roll weight from width, gauge and length?
For polyethylene stretch film, a practical estimate is width in inches multiplied by gauge multiplied by length in feet multiplied by 0.000002403. The result is approximate net film weight in pounds before core and packaging weight.
How do I calculate stretch film length from roll weight?
Use length in feet equals net film weight in pounds divided by width in inches, divided by gauge, divided by 0.000002403. Subtract core and packaging weight before using the formula when the roll weight is gross weight.
Why do two stretch film rolls with the same size have different weights?
Roll weight can differ because of actual thickness tolerance, resin density, roll length, film width, core weight, packaging, pre-stretch level and whether the label states gross or net film weight.
