CNC Glass Interlayer provides non-adhesive smart films for glass lamination using EVA film. The films come in standard fixed widths of 120cm, 150cm, or 180cm and any length. The quantity purchased is based on the standard size needed to cut the required custom size, including any waste. Examples show how a size of 110cmx80cm would use 120cmx80cm, and 50cmx50cm would require two cuts from 120cmx50cm. Optional electrical transformers for powering the films are also available.
