HLP Klearfold products

We are the world leader in radio frequency (RF) creasing. While other methods produce clear plastic boxes with stiff or fragile scores and sharp edges, our proprietary Soft Crease scoring technology uses RF energy to cause a controlled displacement of material from the score lines. This results in more uniform creases, with less folding resistance, ensuring that Klearfold^® clear plastic boxes fold precisely, have clean lines, and maintain their crisp shape. We are unique in our ability to RF crease APET and RPET box-grade plastics, to produce environmentally-preferred plastic boxes with superior strength and performance characteristics.

Having developed proprietary gluing systems, HLP Klearfold is extremely proficient at producing Soft Crease auto-bottom style clear plastic boxes. And for hand-fill applications, nothing compares. Our clear plastic boxes set up quickly and easily by hand, and time and motion studies reveal significant labor cost savings (up to 30%) over standard tuck cartons.
