Besides being environmentally-friendly, Goodpack's solutions provide cost savings of about 20 per cent to clients, said Ho Pei Hwa of DBS. On top of that, Goodpack has 15 more years to its design patent for the IBC. Coupled with the stickiness of its current clients, and the estimated US$900 million needed in capital expenditure for another player to match Goodpack's fleet size, there are significant barriers to others entering the industry, pointed out OCBC analyst Yap Kim Leng. The firm was founded in 1989, when Mr Lam, who was a rubber trader then, saw the need to solve a packaging problem that plagued natural rubber buyers - splinters, sawdust and other debris from wooden crates used to package natural rubber bales were contaminating the commodity.
