Embossed plastic films for safety glazings

摘要

Plastic film comprises a surface structure made of parallel rows of isolated protrusions (a) at least on one side. The quotient of the length and width of the protrusions is 2-50 and whose parallel rows are arranged offset from each other such that a number of protrusions of are added periodically at the border of the adjacent rows and have a common valley at the height of the base surface of protrusions.
