Biodegradability Study on Films for Packaging Based on Isotactic Polypropylene Modified with Natural Terpene Resins
This chapter discusses the influence of a natural terpene resin, poly (α-pinene) on tensile behaviour, gas permeability and biodegradability of isotactic polypropylene (iPP)-based films. The presence of poly(α-pinene) confers improvement of physical and mechanical properties of films, compared to those of plain iPP.
To test the biodegradable behaviour of these innovative films for general packaging uses, several microbial communities isolated from the polluted area were used. It was found that one microbial community, C.B.1, was able to erode the blend films and not the plain iPP film.
