They are especially well suited for food packaging and industrial usages because of their high productivity. Many studies on the stretchability with regard to crystal structure changes have been reported by various researchers because the machine speed has been increasing and the demand to produce thinner films has been becoming more important. Furthermore, a number of studies on the surface structure of BOPP films with craterlike roughnesses have been reported since the 1980s. Although a craterlike surface roughness was formed under specific film process conditions, the formation mechanism and the controlling method of the craterlike film surface are yet to be clarified. In this report, we demonstrated a new hypothesis for the craterlike film surface roughness formation mechanism by analyzing the morphology of the surface layer of polypropylene (PP) sheets and by investigating the relationship between the surface structural changes and the changes in the entire structure. As a result, we found that an overcritical crystallization time was needed to form the crater on the surface of the BOPP film, and the crater formation mechanism was closely related not only to the surface structure changes but also to the deformation phenomenon of the spherulite in the PP sheet during stretching. Furthermore, this report shows the controlling factors in the formation of the crater structure from the viewpoint of the production conditions. © 2012 Wiley Periodicals, Inc. J. Appl. Polym.
