How do you calculate roll scrap cost?

Multiply scrapped length by the loaded value per meter and by the unrecoverable share, then add the disposal fee. For 3,000 m at $0.85/m, 85% unrecoverable, plus a $300 fee: 3,000 x 0.85 x 0.85 + 300 = $2,467.50.

What is the cost per meter in the example?

Total scrap cost of $2,467.50 divided by 3,000 scrapped meters gives $0.8225 per meter, which blends the unrecoverable material value with the fixed disposal fee spread across the footage.

Why apply an unrecoverable share instead of the full value?

Much film scrap can be reground, reclaimed, or sold to a recycler, recovering part of its value. The unrecoverable share (85% here) counts only the value you truly lose, so you do not overstate the cost of scrap that gets reprocessed.

What should loaded film value per meter include?

Roll it up from resin cost, any coating or lamination chemistry, and the conversion labor and overhead already added at the point of scrap — a coated, slit meter is worth far more than raw extruded web.

How can I reduce roll scrap cost?

Cut startup waste with faster line-out procedures, tighten gauge and coat-weight control to reduce off-spec footage, improve edge-trim recovery, and route more scrap to regrind or reclaim to lower the unrecoverable share.

Roll scrap cost vs web break cost — how do they differ?

Roll scrap cost prices the wasted material itself by length; web break cost prices the downtime and restart penalty of the tearing event. A single break usually generates both, so track them together but do not double-count the scrapped film in both tools.

Specialty Films, Membranes & Barrier Materials calculator

Roll Scrap Cost Calculator

Roll scrap cost captures the true dollar loss when film has to be discarded — startup waste, off-gauge footage, coating defects, and edge trim — weighted by how much of that material is genuinely unrecoverable rather than reground or reprocessed. On a specialty film line the loaded value per meter can be substantial once resin, coating chemistry, and conversion labor are baked in, so accurate scrap costing tells you where to aim yield projects. Production and cost engineers use it to price a scrap event, justify regrind or reclaim investments, and set realistic yield targets. It converts meters of waste into a total you can defend and a per-meter cost you can benchmark.

What this calculator does

Estimate the cost of scrapped film rolls including off-spec web, edge trim and core ends that cannot be reclaimed.
A converting plant prices its roll scrap to target the biggest yield-loss source on a barrier film line.
It computes total roll scrap cost as scrapped length times loaded value times the unrecoverable share plus a fixed disposal fee, then divides by length for a per-meter cost.

Formula used

Total roll scrap = scrapped length x loaded value x unrecoverable share + disposal fee
Cost per meter scrapped = total roll scrap / scrapped length

Inputs explained

Scrapped film length:
Loaded film value:
Unrecoverable share:
Disposal and handling fee:

How to use the result

Use it whenever you cost a scrap event, set yield targets, or evaluate whether reclaim or regrind capital is worth funding.
It uses one blended loaded value per meter, so it will misprice scrap when startup waste (low value) and finished coated web (high value) are lumped together at a single rate.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
