The paper aims to research effects of polyethylene (PE) film, polylactic acid (PLA) film, polyhedral oligomeric silsesquioxane (POSS) modified PLA film, silicone rubber (SR) film and modified SR film on carrot protection were studied with freshly cut carrots as packaging objects. The structure and properties of the packaging film were tested by Fourier transform infrared spectroscopy and ultraviolet-visible spectroscopy, and the change of carotene content and the weight loss rate of carrot in different packaging were determined. Different packaging films had different protection effects on freshly cut carrots, especially on the retention rate of carotene. The modified SR film had a low UV spectrum transmittance. It had the best protection function for the freshly cut carrot carotene and a high water retention rate. The PE membrane had high UV permeability and poor protection for carotene, but the weight loss rate of freshly cut carrots in packaging was the smallest. POSS-PLA membrane and PLA membrane had a moderate protective effect on carotene, and high weight loss rate of freshly cut carrots. In the actual packaging application, the combined use of modified SR film and PE film can be considered.
