dc.abstract.enLinear low-density polyethylene (PE) containing an inclusion complex composed of β-cyclodextrin and d-limonene (CD-lim) is proposed as an innovative food wrapping material with antimicrobial features. PE/CD-lim composites are prepared by conventional, high-volume processing, and the optical and mechanical properties of the developed formulations appear suitable for their use as food packaging materials. Compared to plain PE, the PE/CD-lim films have improved haze and UV–vis outcomes, but also decreased gloss values. Addition of CD-lim slightly increases water uptake, up to levels suitable for the foreseen application. It also allows to improve performance of PE as food packaging material, since the PE/CD-lim composites provide barrier to ultraviolet light, an added value for packaging of fatty acids-containing food items, whose shelf life is often limited by oxidation caused by UV light. Most importantly, PE/CD-lim composites exhibit significant antimicrobial properties against a wide range of microorganisms, including fungi and bacteria. Hence, PE films containing CD-lim display suitable properties to play a role as active food packaging films.
