The low‐density polyethylene (PE)/waste paper composites with different components ratio were prepared by extrusion. The photochemical stability of these samples and crystallinity degree of PE in blends were studied using ATR‐FTIR spectroscopy. The thermal properties of composites were estimated by thermogravimetric analysis. Moreover, the morphological changes were observed by SEM. It was found that after long‐term exposure to UV (100 h) composites undergo more efficient photo‐oxidative degradation when compared with pure PE. Also the thermal stability of composites obtained is lower than that in PE. The results indicate that such a material is characterized by high susceptibility to environmental decomposition. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 2197–2206, 2007
