Corona Treatment of Films

LDPE, HDPE, PP, mPE

Blueridge Films can Corona Treat (upon request) on Low Density, High Density, Metallocene (mPE) and Polypropylene plastic films. We can treat one side or both sides depending on which extrusion process is used.

Depending on the method of printing or coating and type of film to be treated, value of required dyne level can vary.

TIPS:

      (1) Low Density Polyethylene (LDPE) films have natural (untreated) dyne level of 31-32. LDPE generally contains slip additives which migrate to the surface over time and reduces the initial dyne level.
      (2) High Density (HDPE) films have natural (untreated) dyne level of 35-36. HDPE has no slip additives and therefore dyne level is stable over time.
      (3) Polypropylene films on the other hand, drops the dyne level very rapidly after initial treat and may require secondary post treatment to bring back the required treat level.
      (4) Films Contaminated with moisture, human skin contact, dirt, poor handling, prolong storage etc. may affect the treat level adversely.

Following are general guide lines for suggested treatment levels for Polyethylene, Metallocene and Polypropylene films:
