Soft Crease ® Scoring


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.

Our proprietary E-Z Crease® scoring, which does not use RF energy, can be used to produce PP cartons. It may also be appropriate for PET grades used in non-packaging applications.
