For over 45 years, HLP Klearfold has been the clear plastic packaging market leader. We are the world's largest and most accomplished clear plastic box manufacturer. In addition to producing clear plastic boxes, HLP Klearfold is a leading provider of custom thermoforming, clear plastic sleeves, clear plastic tubes and rounds, and other clear packaging innovations like our Klearfold® Keeper and InSight® visual packaging systems, and our Duofold® plastic/paperboard combination packaging.
No other clear packaging manufacturer has our experience and global scale. And no one is committing more to technology investments and process innovation to better serve their customers. Our proprietary Soft Crease® scoring technology produces APET and RPET plastic boxes with uniform creases that fold precisely with less folding resistance. And the precision and uniformity of Soft Creasing ensures that Klearfold® plastic boxes perform efficiently on automated filling equipment or in hand-filling applications.
