The low thickness of plastic films poses a challenge when using near-infrared (NIR) spectroscopy as it affects the spectral quality and classification. This research focuses on offering solution to classifying multilayer film materials with focus polyolefin plastics. It presents importance accurate aim is demonstrate suitability handheld NIR spectrometer in assess impact various measuring backgrounds (white tile, Teflon, aluminum, copper, silver, gold) classification accuracy wavelength range 1596–2396 nm. Metallic have been found enhance accuracy. was consistently high, ranging from 96.55% 100%, aluminum gold yielding best results theoretical In experimental classification, reached 100% any metallic were used. Conversely, Teflon showed theoretically high 96.21% but only achieved an 72.2%. These findings suggest that can improve plastics (films) complex material composition (multilayers).
