A multi-laminate film includes a first biaxially oriented film having a first machine direction angle and a first spiral cut oriented film having a second machine direction angle different than the first machine direction angle. The multi-laminate film also includes at least one of a second biaxially oriented film having the first machine direction angle or a second spiral cut oriented film. The first biaxially oriented film, the first spiral cut oriented film and the at least one of the second biaxially oriented film or second spiral cut oriented film are laminated together.

A curved reflective polarizer includes a plurality of polymeric layers stretched and shaped along at least orthogonal first and second directions so that at least one location on the curved reflective polarizer has a radius of curvature in a range from about 6 mm to about 1000 mm along each of the first and second directions. For light having a predetermined wavelength and incident on the reflective polarizer along a direction parallel to an optical axis normal to and passing through the reflective polarizer at a center of the reflective polarizer, each location on the reflective polarizer has a maximum reflectance 10 greater than about 70% and a corresponding minimum transmittance less than about 5% for a block polarization state.

The present invention relates to a self-adhesive waterproof coiled material of a super-strong cross laminated film, comprising sequentially from top to bottom: an isolation protection layer, a non-asphalt-based self-adhesive layer, a strong cross laminated film, an asphalt self-adhesive layer and a PE isolation film. One side of the upper surface of the coiled material is provided with an overlap edge, and the other side of the lower surface of the coiled material is also provided with an overlap edge. The waterproof coiled material provided in the present invention has better adhesive property with post-cast concrete than an asphalt-based coiled material, and can be better bonded to a main body structure (i.e., pre-paving anti-sticking coiled material); the strong cross laminated film in the middle of the coiled material has good ductility, so that when the base layer slightly subsides or the main body structure is slightly deformed, the coiled material can continue to be well bonded to the main body structure and would not be separated; and a good waterproof effect thus can be achieved.
