BOPP Tape Roll Output Calculator

BOPP Tape Jumbo Roll Output Calculator (Dynamic Roll Variants)

Smart Calculator for Packaging Tape Slitting

In a BOPP tape manufacturing or slitting unit, one of the most common questions is: how many small rolls can be produced from one jumbo roll? Doing these calculations manually for different customer sizes (width × length) is time‑consuming and often leads to mistakes.

This BOPP Tape Roll Output Calculator helps you solve that problem. You can enter your jumbo roll details once and instantly see the output for multiple roll size variants.

What does this calculator do?

• Calculates usable jumbo width from jumbo width and trim loss per side.
• Lets you set one main roll size as Variant 1 (width in mm × length in meters).
• Allows you to add extra sizes using the “+ Add Variant” button for additional roll variants.
• Shows rolls per width, rolls per length, total finished rolls, and leftover width/length for every variant.

Calculation logic (simple formulas)

• Usable width = Jumbo width − 2 × trim loss per side.
• Rolls per width = Usable width ÷ required roll width.
• Rolls per length = Jumbo length ÷ required roll length.
• Total finished rolls = Rolls per width × Rolls per length.

In this calculator, the core ID is considered as 53 mm fixed, which is a common standard size for packing tape cores. It is shown for information only.

Who should use this tool?

• BOPP packing tape converters and manufacturers planning jumbo roll utilization.
• Slitter‑rewinder operators who need quick on‑floor calculations before job setup.
• Job‑work units preparing quotations for different customer sizes and checking feasibility.
• Production planners looking to maximize output and minimize waste from each jumbo roll.

Jumbo Roll Details

Jumbo Width (mm) Jumbo Length (m) Trim Loss per Side (mm) Usable width = Jumbo width − 2 × trim. This usable width will be used for all variants.

Roll Sizes

By default only Variant 1 is available. This version uses only the main standard size.

Variant 1 (fixed) Main standard size

Roll Width (mm)

Roll Length (m)

For this variant: Rolls per width = Usable width ÷ roll width, and rolls per length = Jumbo length ÷ roll length.
