Information about tests

Curvature of films

This method is used to measure the curvature of a flat film in relation to the longitudinal direction. This so-called curvature can be the result of an aslope bubble during the blown film process, for example. The film then tends to have lobed edges on the reels or to wrinkle during lamination. We will be happy to send you our test specification on request.
