Grammage, yield

Determination of the grammage (e.g. plastic film and fabric or nonwoven, packaging film, paper and cardboard, aluminum foil for thickness measurement), calculation of the yield (in the dimension [m²/kg material]).

In short — AI-generated

The grammage test determines the mass per unit area of packaging materials such as plastic films, paper, or aluminum foils. A defined sample area is cut out and weighed precisely on a laboratory scale to calculate the mass in grams per square meter (g/m²).

The resulting value is used to verify material specifications and ensure consistent quality during production. By calculating the yield in square meters per kilogram, buyers and developers can accurately determine material consumption and optimize packaging costs.
