Abstract
A composite foil or laminate of two synthetic-resin foils having mutually transverse main stretch directions (orientations) is formed by bonding the foils together after they have been incised in rows of spaced-apart incisions extending in the main stretch direction of each foil. Successive alternating rows along the foil have incisions offset along the rows from one another.
