Calculateur de Poids & Matière de Carton Ondulé

How to use it: enter the RSC length, width and height on one consistent basis, plus converting allowances, the two liner GSM values, medium GSM, measured or specified flute take-up, glue contribution and quantity. If your dimensions are internal finished dimensions, the allowance fields must bridge them to the supplier's scored blank; do not mix internal and external measurements.

Formula. Board GSM = outer liner + inner liner + medium x take-up factor + glue. Weight = estimated blank area x board GSM. The RSC blank uses two length and two width panels, one width of top/bottom flaps, and the entered tab/allowances.

Worked example. The starting board inputs give 175 + (140 x 1.43) + 175 + 10 = 560.2 gsm. The calculator multiplies that grammage by the estimated blank area, then by quantity, before applying the entered material cost per kg.

• Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
• Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
• When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

This estimates material weight, not compression strength or a production quotation. Trim, slots, manufacturer allowances, moisture, coatings, ink and measured take-up change actual mass. Replace every nominal input with supplier data before costing production.
