Compatibility testing on capsules, filter, and top lid films are being performed at IMA Coffee Lab with the precise aim to identify and achieve optimum material sealing parameters and limits as well as a suitable set up of IMA packaging machineries to handle the pods successfully.
Tests are carried out under the supervision of IMA Coffee R&D team and in close and constant co-operation with NatureWorks specialists: dedicated tools are used to simulate filter and top lid films sealing phases and adjust parameters according to testing results.
The sophisticated microleakage detection testing performed at IMA Coffee Lab has given more than encouraging and optimistic results allowing a significant step forward in the process that will proceed thoroughly towards the following coffee extraction testing phase.
At NatureWorks, development of new single-stage thermoforming processes and capsule designs continues to produce precise capsules that meet IMA’s specifications for filling and sealing on their packaging machines.
NatureWorks has also constructed a custom Data Acquisition System for K-Cup compatible pods that is being used to understand and benchmark how differing capsule designs perform under various brewing conditions.
“With the promising results we’ve seen so far, we have already begun the next phase of development by partnering with converters in North America to bring these new compostable pod designs to commercial scale making them available to brands and roasters seeking to meet consumer demands for more sustainable packaging and to circular economy directives that specify compostable packaging as a key enabler of recovering food waste for compost,” said Flavio Di Marcotullio, Global Industry Manager, Single Serve Beverages, for NatureWorks.
