This type of cardboard is used to obtain greater resistance of the tube to crushing and friction with rotating pins. Grammages range from a minimum of 190 to a maximum of 450 gr/m2

Supplied in strips of 10 - 10.5 - 11 - 11.5 - 12 cm. and higher for manufacturing spiral tubes.
Supplied in rolls with heights between 210 and 230 cm. for manufacturing in-line tubes.

Rolls can be supplied in smaller measurements as long as their combination results in a total height between the minimum and maximum value, for example: 105+105, 110+100, 115+115, 110+110, 148+82, 76+76+76 cm. etc.
