Biaxial orientierte Laminat-Folie aus Polyester

摘要

A biaxially oriented laminate polyester film in which each of the layers contains at least two different lubricant particles, and each of two members out of the lubricant particles of one layer and each of two members out of the lubricant particles of the other layer have the same substrates and the same average particle diameters, respectively, the biaxially oriented laminate polyester film enables the direct recycling of the recovered polymer for production of the film.
