S.C. Johnson uses packaging to innovate

Convinced that consumers would respond warmly to a package of plastic wrap whose film cutter bar was plastic rather than tin plate, marketers at S.C.

Johnson of Racine WI have revamped all cartons for their Saran-brand Cling Plus product. The cartons now have a “finger friendlier” PET cutter bar.

“Considering that most calls to our plastic wrap consumer response center are complaints about the unforgiving nature of the metal cutter bar we saw this as a true consumer benefit” says S.C. Johnson packaging engineer Kris Gerulski.

Why switch to a plastic cutter bar on low-density polyethylene Cling Plus but not on S.C. Johnson’s Saran Original which is polyvinylidene chloride? Because says brand manager Karen Kalman the LDPE has so much cling it’s harder to dispense cut and handle than PVdC. Therefore it needed an improved cutter bar and that’s what the plastic bar is. It has more teeth per inch than a metal blade and they’re patterned in a way that makes for a better cut.

Carton converter Rock-Tenn (Norcross GA) applies the new bar to S.C. Johnson’s packages pretty much the same way that it used to apply the steel bar. Like its steel counterpart the PET piece is supplied in rollstock form on a release liner. Equipment supplied by Carton Edge (Coventry England) pulls the material from a roll removes the PET cutter bar from its release liner and rolls it onto the paperboard carton.

At S.C. Johnson’s Bay City MI plant where Cling Plus is produced and packaged virtually no machine alterations were required when the plastic cutter bar was introduced says Gerulski. He also indicates that the revamped carton costs about the same as the one it replaced.

As for consumers says Kalman they’ve made it clear that they like the new feature a lot.
