In visual packaging, leadership stands out. HLP Klearfold has been manufacturing clear packaging exclusively for over 50 years. We are the world's largest and most accomplished producer of plastic folding cartons… our iconic Klearfold® cartons are the standard by which all others are judged. We are also a leading provider of rolled-edge tubes, custom thermoforming, and visual packaging innovations like the Klearfold® Keeper and InSight® packaging systems, and Klearfold® RPET100, plastic folding cartons made with 100% post consumer recycled PET.. No other visual packaging producer has our experience or scale. Our global approach to our niche market, that is, serving four continents from our very large facility in Southern China, allows us to invest in our business in ways that a company serving just North America cannot. Our production equipment is state-of-the-art and we continue to reinvest in the latest printing and converting technologies to expand capabilities, improve quality, reduce variability, and reduce costs.
