How to use it

  1. Enter the footage on the roll.
  2. Enter the roll width in inches (used for the weight).
  3. Enter the core outside diameter in inches.
  4. Enter the thickness of one wrap in mil. The OD, weight and 3D roll update as you type.

Example

A 24″ wide roll of 1.5 mil film, 5,000 ft long on a 3.5″ core: about 11.3″ OD and 72 lb of film.

Good to know

  • For lay-flat tubing, enter double the gauge: each wrap is two layers.
  • Check the OD against the maximum roll size your unwind stand or bagger accepts.
