Nowadays business is not just for profit making. Rather, business houses across the globe are realizing their stake in the society and hence they have started undertaking various CSR initiatives voluntarily. As per the clause 135 of the Companies Act, 2013 any company having a turnover of Rs 1000 crore or more or a net worth of Rs 500 crore or more or a net profit of Rs 5 crore or more should mandatorily spend at least 2% of their net profits per fiscal year on various CSR activities. Presently in India, CSR initiatives are taken by many companies. Especially, in the FMCG companies where reducing the packaging material is posing a major challenge. Hence, these companies are working in the field of environment, community welfare, health care, education, women's empowerment and girl child care. The present study explores the existing literature available on Corporate Social Responsibility. The contribution of various renowned researchers towards CSR, starting from the first definition given by Bowen (1953), has lead to the development of existing concept of CSR. Further, the study also elaborates upon the various CSR initiatives taken by the two leading Indian FMCG companies: Dabur India Limited and Hindustan Uniliver Limited in different areas.

AbstractCorn starch/polyvinyl alcohol (PVA)/glycerol composite films incorporated with ε-polylysine were prepared, and their properties were investigated. The Fourier-transform infrared (FTIR) spectroscopy indicated that the interactions happened between the amino group of ε-polylysine and hydroxyl group starch/PVA composite films. X-ray diffraction (XRD) analysis showed that the addition of ε-polylysine decreased the intensity of all crystal peaks. Thermogravimetric (TGA) analysis suggested that ε-polylysine improved the thermal stability of composite films. Scanning electron microscopic (SEM) analysis showed that the upper surface of composite films incorporated with ε-polylysine presented more compact and flat surface. The antimicrobial activity of the composite film progressively increased with the increasing of ε-polylysine concentration (P < 0.05). The tensile strength, elongation at break and water absorption significantly increased, whereas water solubility decreased with the increasing of ε-polylysine concentration (P < 0.05). Therefore, the corn starch/PVA/glycerol composite films incorporated with ε-polylysine had good mechanical, physical and antimicrobial properties and could have potential application as a novel antimicrobial packaging material.
