The Pritt Glue Stick – A Genuine Success Story

The very first glue stick appeared in stores over 40 years ago, and was met with instant success. The idea for a glue stick was put forth by Henkel researcher Dr. Wolfgang Dierichs in 1967. That glue stick was sold under the Pritt brand, and it is a true example of good design – it was virtually identical to contemporary glue sticks with twist-action, convenient size, and no melting or oozing. Up to that point, all the glues available were liquid. “The trick was getting the glue to stiffen,” recalled current Henkel product developer, Nils Hellwig. A solid glue was finally created by combining a water-soluble adhesive with a soap gel. The soap created a solid and masked the adhesive’s stickiness, but the product was soft enough to be spread as a film and release the glue. Although the design of the glue stick is largely unchanged, the glue itself has undergone continuous development based on sustainability. Toda,y all Pritt adhesives are solvent free, and approximately 90% of the adhesive in glue sticks is made from natural, raw materials rather than petroleum-based materials. Hellwig explained, “Pritt has been fully committed to this environmentally compatible alternative since the year 2000, with [petroleum-based] PVP having been completely removed and replaced by natural starch compounds. Moreover, since 2012 we have been using a home-grown industrial potato in order to avoid unnecessary transportation.”
