Production process of the bioplastic cartridge
The video content in detail: Sustainable packaging for natural cosmetics? Yes, that's possible too! Hannah and Patrick from freemee cosmetics have been working with us for three years to develop packaging that consists partly of reusable materials and partly of a single-use bioplastic component from NaKu. The basic idea behind the bio-packaging project was to make the entire packaging as sustainable as possible. That's why freemee cosmetics approached us. It was immediately clear to both freemee cosmetics and us that this collaboration would work very well. And that has proven to be true. Soon, freemee cosmetics' natural cosmetics will be available in sustainable cosmetic jars – natural cosmetics in a bioplastic refillable cartridge.
A glimpse into production – Several bioplastic parts are required to manufacture the cartridge. Sometimes a triple injection molding tool is used that - as the name suggests - can produce three injection molded parts of the biocartridge in one operation. We like this project very much because in this project reusable and renewable or natural plastic/bioplastic can be combined. The major challenge in production is that the bio-cartridge consists of five different components that have to be very precisely matched to each other.
After a meticulous development period, the first cartridges could now be produced, and various bioplastic mixtures were tried out and analyzed. Small changes will still take place in the next step so that the end product really meets the high requirements and all components work together optimally. This precise adaptation and coordination of the individual components of the bio-cartridge is necessary because there are also moving parts in the cartridge, which of course have different requirements than if it is only a component with rigid connections.
The sustainable cosmetic jar from freemee cosmetics consists of three main components. The core, the bio-cartridge made of polylactic acid (PLA), i.e. a bio-plastic, is located in the square outer shell made of wood (nut or oak). The respective cream is in this cartridge, by turning the rotating glass attachment, a slide moves through a threaded part made of bioplastic inside the bio-cartridge, which in turn transports the cream to the opening upwards. The big advantage of this principle: there are no cream residues left in the bio-cartridge and the annoying scraping out of the last cream residues is no longer necessary. This means that valuable resources are not thrown away unused, as is unfortunately still the case with many packaging solutions, even today. With this sophisticated dispenser system for the natural cream, the optimal dosage of the cream quantity is also guaranteed.
Feedback from freemee cosmetics
Hannah and Patrick from freemee cosmetics have specialized in developing and producing natural cosmetics in a sustainable jar. Hannah makes the cosmetics and has decided to put the rose at the center of natural cosmetics. Patrick is busy developing the packaging. The packaging is a combination of glass, wood and our bioplastic inner cartridge. Hannah and Patrick work with us because we can produce the inner cartridge for the creams from bioplastics. The company philosophy of freemee cosmetics is that everything is produced sustainably and regionally. After the first appointment with freemee cosmetics and NaKu, it was already clear to Hannah and Patrick that they simply had to implement this packaging project with NaKu.
