Details
Rigid polycarbonate extruded 24" wide with deep moire embossing creating a dramatic, 3-dimensional effect. Sommers Plastics Lenticular in Rolls “LIR”
Material Description
Lenticular in Rolls “LIR” is a multi-lenses effect thermoplastic film manufactured of polycarbonate, flexible PVC and PETG. LIR gets its effects of motion and dimension from thousands of minute parabolic lenses that are molded into the surface on both sides of the film. These lenses create a pattern of absorption and reflection that are remarkable and unique. Shimmering silk, stardust sparkles; geometric repetition and three dimensional are some of the ways to describe LIR
Sommers’ materials also lend themselves to many downstream processing methods. Printability is the key to LIR applications. Silk screening, litho and flexo are just a few of the printing methods that have been successfully utilized on Sommers’ LIR. Polycarbonate and PETG can be easily hot stamped for rich and varied effects. LIR can also be easily die cut and adhesively bonded to many different substrates.
Applications
Applications for LIR are as varied as the imagination allows. It has been used in packaging, point-of-purchase displays, vending machines, clothing, apparel and accessories, business cards, decals, home furnishings, CD packaging, sporting goods and many other ingenious applications.
Material Form and Supply
Sommers’ LIR is available in both rolls and sheets. Material is produced at 25 3/8” wide (24” of useable surface guaranteed) and 0.015” think. Polycarbonate, flexible PVC and PETG are all available in roll form. Polycarbonate and PETG are all available in a standard sheet size of 25 3/8” x 54”. Custom sheet sizes are also available
