DuPont™ Surlyn® Relieves Pain of Delamination for Salonpas
DuPont Surlyn® resin improved seal integrity
Hitsamitsu Vietnam Pharmaceutical Co. Ltd. of Bien Hoa, Dong Nai Province, Vietnam, manufactures Salonpass, a medicated muscle pain reliever for topical applications. But the high levels of camphor and menthol -- the active ingredients in Salonpas that make it so effective -- were causing the packaging structure to delaminate and the foil to corrode. Replacing the low density polyethylene in the package with DuPont Surlyn® resin improved seal integrity and protected the foil -- as well as allowing higher line speeds, a low sealing temperature and better hot tack.Because DuPont cannot anticipate or control the many different conditions under which this information and/or product may be used, it does not guarantee the applicability or the accuracy of this information or the suitability of its products in any given situation.
