A system for laminating an adhesive to a component includes a liner including a first major surface facing the component and a second major surface opposite to the first major surface. An adhesive is disposed on the first major surface. The adhesive is configured to be laminated to the component. A support pad engages the second major surface of the liner for laminating the adhesive to the component. Each of the support pad and the liner undergoes deformation upon engagement of the support pad with the liner. The support pad includes a body made of an elastic pad material and includes an upper surface facing the component, a lower surface opposite to the upper surface, and a lateral surface disposed between the upper surface and the lower surface. The liner includes a conformable liner material having a liner elastic modulus from about 5 megapascals (MPa) to about 650 MPa.

System and method of lamination

An optical film includes a plurality of alternating first and second polymeric layers, such that the first polymeric layers have a smaller average in-plane index of refraction than the second polymeric layers and the first polymeric layers have a glass transition temperature of at least 107 deg. C. The optical film may be a reflective polarizer. An optical stack includes a linear absorbing polarizer and the reflective polarizer disposed on, and bonded to, the absorbing polarizer. The reflective polarizer has an optical reflectance of at least 60% for a first polarization state and an optical transmittance of at least 60% for an orthogonal second polarization state. When heated at 105 deg. C. for 15 minutes, a difference in shrinkage of the reflective polarizer and the absorbing polarizer along the first and second polarization states is greater than about zero and 0.2%, respectively.
