  • Patent number: 10576718
    Abstract: An improved multilayer polymer film is disclosed. The film may include a first skin layer, a second skin layer, and an intermediate layer between the skin layers. The first, second and intermediate layers may be formed of respective first, second and intermediate polymer compositions. Each layer may have distributed therein particles of titanium dioxide to a weight content of from 6 percent to 14 percent. One or both the second skin layer and the intermediate layer may have distributed therein non-white pigment particles to a weight content of from 0.050 percent to 0.15 percent of such layer(s). The contents and distribution among layers of the pigments may provide for relatively disproportionate improvement of opacity while preserving a neutral white color surface to receive ink-printing, enabling high conformity of printed colors with target colors, and preserving weldability of the film to itself.

  • Publication number: 20190001660
    Abstract: The present invention relates to a process for flexographic printing of ink onto a thin polymeric film substrate. In particular the process relates to printing using a central impression cylinder press, wherein the width of printed substrate is greater than 800 mm, to provide a high opacity printing process. According to the present invention the printing process comprising: transferring ink from an ink reservoir to an anilox roll; transferring the ink from the anilox roll to a printing plate wherein the ink volume transferred by the anilox roll is from 9-20 cm3/m2; and applying the ink to the surface of the substrate by applying pressure between the printing plate and an impression surface and passing the substrate between the printing plate and the impression surface wherein the printing plate is a high definition printing plate comprising at least 40 lines per centimeter.
