100% biodegradable caps from API and Sacmi

A 100% biodegradable cap for mineral water bottles has been produced in a cooperative venture between the raw materials producer API and the processing line manufacturer Sacmi. The cap was presented at Packology (Rimini, June 11-14) and will be featured again at Drinktec (Munich, September 16-20) and at K (Düsseldorf, October 16-23). The cap was made starting with an Apinat Bio compound produced by API. Thanks to its chemical structure, the compound is versatile and easily processed using the most common technologies and has a broad potential range of applications in many sectors. The compression moulding technology developed by Sacmi for the production of bottle closures proved optimal for the compound, especially regarding its rheology and melt behaviour, achieving an excellent outcome both in terms of production volume and quality of the finished product.
