Sealing values N/15mm
AL / APET → N/15 mm: 12 (Brugger-HSG C 200°C, 1 sec, 460N, Tolerance ±2)
AL / PS → N/15 mm: 14 (Brugger-HSG C 200°C, 1 sec, 460N, Tolerance ±2)
AL / PP → N/15 mm: 14 (Brugger-HSG C 200°C, 1 sec, 460N, Tolerance ±2)
PET / PS → N/15 mm: 10 (Brugger-HSG C 200°C, 1 sec, 460N, Tolerance ±2)
PET / PP → N/15 mm: 10 (Brugger-HSG C 200°C, 1 sec, 460N, Tolerance ±2)
The specified values apply at 200 °C. Adhesion decreases as the temperature decreases.
The effective sealing range is between 180 °C and 205 °C.
Paper must be NC primed.
