摘要

The disclosure relates to a method of producing crease-lined packaging material with a high degree of accuracy as regards the placing and forming of longitudinal crease lines. A web-shaped starting material (1) is provided, in connection with the laminate production, with a pattern of crease lines (6) extending at an angle to the longitudinal direction of the web, whereafter the material is divided into part webs (9). In connection with the conversion of each part web (9) into individual packaging containers in a filling machine, each part web is provided with complementary, longitudinal crease lines (17, 18).
