Abstract:
Polymeric films, which may be adhesive films, and display devices including such polymeric films, wherein a polymeric film includes: a first polymeric layer having two major surfaces, wherein the first polymeric layer includes a first polymeric matrix and particles. The first polymeric layer includes: a first a polyolefin-based low WVTR adhesive polymeric matrix having a refractive index n 1 ; and particles having a refractive index n 2 uniformly dispersed within the first polymeric matrix; wherein the particles are present in an amount of less than 30 vol-%, based on the volume of the first polymeric layer, and have a particle size range of 400 nanometers (nm) to 3000 nm; and wherein n 1 is different than n 2 .
Abstract:
A method of web cleaning, particularly relatively soft polymeric webs, without using dipping baths or ultrasonic energy. The method includes conveying the web against a backup roller and spraying the web with a high pressure liquid while the web is supported by the backup roller. Thereafter, residual fluid from the high pressure stream is stripped from the web by a gas curtain while the web is supported by the backup roller. In many convenient embodiments, the web is contacted with a cleaning roller while the web is in contact with the backup roller.

Abstract:
In one embodiment, a computer implemented system and method for selecting dimensions of a die is disclosed. The method may include prompting a user to select a coating uniformity required to produce a particular coated product with the die. The user may also be prompted to select a slot height of the die. In some embodiments, the user may specify a value for one or more dimensions of the die. The method may then determine the total indicated run-out (TIR) of the coated product as a function of the dimensions of the die not having a user specified value. In certain embodiments, the method provides a thermal treatment process for reducing the number of finishing (e.g., grinding) cycles needed to produce a desired die flatness. In another embodiment, a computer implemented method for designing a coating die to achieve a desired coating uniformity with a particular coating fluid having a specified rheological characteristic is disclosed.
