Pella Corp. is widely recognized as the country's second-largest producer of prime windows. What's not so well known is that the firm is exercising a leadership position in packaging and shipping innovation. The Pella IA-based company is now completing a major packaging change for its windows that has taken several years to implement in all window styles and in all plants. Today the company is using a minimum of paperboard and stretch film that not only protects the costly windows but allows truckers and other distribution employees to see exactly what they're handling. This has led to a noticeable damage reduction though the company declines to quantify. Pella first applies corrugated die-cut telescoping corners that protect the window jambs. With these protective corners in place the individual window is stretch wrapped in 80-ga Mobilrap(TM) S film from Mobil Chemical (Pittsford NY). Each wrapped window is then loaded into trailers vertically on end much like books in a bookshelf. This technique not only reduces the amount of packaging used it also has reduced handling damage and cut costs.
