money in nappies

This stock's been on a gradual up for a while now. They don't seem to have done much so far but my gut feeling is that something's on the horizon. Their biodegradable nappy is a timely product and with the right branding and marketing this company could go far. Last year Japan's Unicharm purchased APPP (Australian Pacific Paper Products) - Australia's second largest nappy manufacturer with 20 % of market share for $165 Million. Gresham Private Equity, controlled by Wesfarmers, was the owner of APPP. So there's money in those nappies or diapers - whatever you want to call them!
Anyone got any opinions or heard about what's going on with them? I think they look a pretty good buy.
