Wiegand-Glas has developed a patented polymer coating system,"WPT" that either lightweights glass bottles by 30%, or increases their internal pressure strength by over 40%. On-line, at the end of the lehr, the glass container is dipped in polymer, receiving an extremely thin coating, which is immediately UV cured. The "WPT" system is the only on-line coating process, and the coated bottle is totally recyclable.
