Let me set the scene…You are shaking a bottle of ketchup for the last drops when a disturbing farting noise ruins your appetite, not to mention your popularity. We’ve all been there. Not only can these sticky condiments be embarrassing, but they also pose problems for plastics recyclers. According to Sciencedaily.com (full article here), researchers from the Fraunhofer Institutes for Process Engineering and Packaging IVV are working with Munich University of Technology to develop non-stick packaging. In three years time you may never have to shake, tap or beat the bottle to get the last drops because it will slide right out. Sounds like progress.
