LAMINATION WITH HIGH LINEAR SHEARING PROPERTY

摘要

PURPOSE:To reduce lateral and vertical shearing propagation resistance and improve shearing linearity by laminating polyacetal resin film manufactured by processing method such as inflation or T die and film with low splitting property. CONSTITUTION:At least one layer of a lamination is constituted with polyacetal resin film with superior linear splitting property in an extrusion and a rectangular direction. For instance, polyacetal resin film with 25mum and 30mum of thickness prepared by an inflation method is laminated with a 12mum-thick polyethylene terephthalate resin film using a dry lamination method to manufacture a laminated film.
