Over 50 Years of Creating Klearfold® Plastic Folding Cartons
Clemson University White Paper - Clearly Disruptive Packaging
For over 50 years, HLP Klearfold has been the clear plastic packaging market leader. We are the world’s largest and most accomplished manufacturer of plastic folding cartons, as well as a leading provider of custom thermoforming and clear plastic tubes and rounds. We have created many innovations, like the Klearfold® Keeper and InSight® visual packaging systems, RPET100 folding cartons made with 100% postconsumer PET, and the Klearfold Keeper CR, a certified child-resistant package.
No other clear packaging manufacturer has our experience or global scale. And no company is more committed to technology investments and process innovation to better serve its customers. Our proprietary Soft Crease® scoring technology produces APET and RPET plastic boxes with uniform creases that fold precisely with less folding resistance, ensuring that Klearfold® plastic boxes perform efficiently on automated filling equipment or in hand-filling applications.
