Wax paper has been used for twist wrapping candy and cough drops for nearly a hundred years. The Model K twist wrapper was introduced in 1919 and ran 140 pieces a minute of taffy. But over the decades, machines have advanced, speeds have increased, and many manufacturers have abandoned the material as alternatives with different properties have come on the market, including cellophane, and later CPP and UltraWrap. While wax paper is still a very cost-effective material, there are several inherent problems that cause headaches for manufacturers. For example, wax has a tendency to build up on machine parts, which requires regular shutdowns for cleaning. Wax paper naturally contains water (upwards of 6 percent depending on the grade), and strives to keep that water in the film. In dry conditions, the paper will actually absorb water from the candy, and will dry out the candy. Conversely, in high humidity, wax paper will transfer excess moisture to the candy, making it sticky and unappetizing. Lastly, wax paper in storage is likely to dry out over time, creating rips and tears when wrapping candy.
Regardless, salt-water taffy, cough drops, and a few other candies are still wrapped in wax paper, and for years, we have been asked if we have a film that looks and feels like wax paper, but without the problems associated with wax paper. Introducing PaperEx, a new twist wrap material from Multifilm that looks and feels like wax paper, but performs like a plastic film. No ripping or tearing, no candy sticking to the wrapper, and no need to shut down the line to clean the wax build-up.
PaperEx has been in development at Multifilm for close to a decade, and a recipe has been perfected that offers the matteness of wax paper with the ease of use and simplicity of cast extruded film.
