Micron to Gauge
Convert micrometer thickness to plastic-film gauge where 100 gauge equals one mil.
Gauge to Micron
Convert plastic-film gauge to micrometers using 0.254 µm per gauge; metal-sheet gauge is a different system.
Film Density from GSM and Thickness
Calculate an apparent film density from measured GSM and thickness as a check on material assumptions.
Film Thickness from GSM and Density
Back-calculate the thickness of a homogeneous film using known GSM and an editable density.
Roll Weight from Length

Estimate the finished roll outer diameter for a given film length, thickness and core outside diameter.
Roll Weight from Diameter
Estimate roll film weight by deriving running length from diameter and applying web width and GSM.
Roll Diameter from Weight
Convert net film weight to running length and estimate the resulting outside roll diameter.
Roll Area
Calculate the film area in a roll from web width and running length, with optional net weight from GSM.
Remaining Film on Roll
Estimate remaining length and area from the current roll diameter, and remaining weight when GSM is known.
Gross Roll Weight
Add net film, core and packaging weight for handling or transport; enter core weight or estimate it from geometry.
Core Weight
Estimate the mass of a hollow cylindrical core from outside and inside diameters, width and editable material density.
Rolls Required
Round required roll count upward from weight or running length and see the resulting excess material.
Roll Cost per Linear Meter
Allocate the film roll price over its running length to compare costs per linear meter.
Laminate GSM
Build one to six material layers and account for dry adhesive, ink and coatings to estimate total laminate basis weight.
2-Ply Laminate GSM
Calculate the combined basis weight of two films and their adhesive interface using editable thicknesses and densities.

Laminate Yield
Construct a laminate and convert its total GSM, including dry additions, into square meters per kilogram.
Laminate Cost per m²
Cost each material layer from thickness, density and price per kilogram, then add adhesive, ink and coating costs.
Adhesive Consumption
Calculate dry and wet adhesive requirements from laminate area, target dry coat weight and adhesive solids content.
Adhesive Cost per m²
Translate dry coat weight into wet adhesive consumption and material cost per square meter at the entered solids percentage.

Measure the material cost of process scrap and deduct an optional scrap recovery value to find net loss.
Units per Linear Meter
Convert pack repeat and lane count into units per running meter and meters per standard production quantities.
Stretch Film Cost per Pallet
Weigh representative actual qualified wrap cycles. Include tails and rewraps in the measurement. Measured consumption avoids guessing savings from nominal prestretch or thickness.
Pallets per Stretch Film Roll
Exclude the core and wrapping. Round complete loads down and show residual film separately; tail and rewrap consumption belong in measured grams per load.
Stretch Film Consumption Comparison
Compare representative measured consumption after performance qualification. The planning period is the entered load count, not an assumed year.
Shrink Film Cost per Bundle
Enter the full opened web width, twice the folded width for centre-fold film. Cut length comes from the actual qualified process, not a guessed product perimeter.
Before you start
Start with the job: material conversion, roll planning, laminate structure, pouch production or supplier comparison. Keep thickness, measured GSM and quotation units consistent as you move between tools.
