Patent number: 10576718Abstract: 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.Type: GrantFiled: June 30, 2017Date of Patent: March 3, 2020Assignee: The Proctor & Gamble CompanyInventors: April Renae Brown, Norman Scott Broyles, Gary Wayne Gilbertson, Christian Kohlweyer, Fei Wang
