The co. says that its Spectra-kote coating and WAM(TM) medium for corrugated boxes has been certified by the Fibre Box Assn. protocol standards for recyclability. As one of the first alternative coatings to be certified, Spectra-kote is a moisture barrier that holds out water and vapor while maintaining its ability to be recycled with regular corrugated containers, the co. says. The coating provides an alternative to nonrecyclable wax though a special technology. Although corrugated has one of the highest recycling rates of all materials, some of it (about 5 percent, according to the co.) isn’t recyclable. It represents about 3 billion lb of corrugated that the co. says eventually gets landfilled every year. The coatings and the WAM medium are said to prevent water absorption by the paper and with the recent certification for recyclability, that recycling rate can climb even higher, the co. reports.
