Work through the task
- Identify net material quantity and the original quoted unit. A reel price needs its actual net contents, not gross weight including the core.
- Use measured complete-structure GSM for mass-to-area conversions and actual web width for running metres. Keep estimated GSM visibly provisional.
- Transfer a verified price into comparison, then add the other supplier, shipment quantity and explicitly known freight and tooling.
Tools for this job
Film Price per kg to m² Calculator
Convert a film quotation from price per kilogram to price per square meter using measured GSM or a thickness and density estimate.
Open calculator →Film Price per kg to Linear Meter Calculator
Calculate the cost of one running meter from film price per kilogram, web width and GSM.
Open calculator →Roll Price to Price per kg Calculator
Divide the quoted roll price by net film weight to compare the material cost per kilogram.
Open calculator →Flexible Packaging Quote Comparison Calculator
Normalize two to four supplier quotations across weight, area, roll and pack bases, with explicit specification and currency checks.
Open calculator →A worked example
Illustrative film at 60 GSM and EUR 3/kg costs EUR 0.18/m². At 0.8 m width it costs EUR 0.144 per running metre. These conversions describe material price; delivery and setup are additional unless included in the quote.
Use your supplier specification and quotation. These numbers demonstrate the arithmetic; they are not market prices or a packaging suitability assessment.
Checks before you decide
- Original price unit and currency
- Measured GSM of the complete film
- Actual width and matching specification
