Exciting new technologies from PVD Advanced Technologies

Exciting news from the PVD office - we have been working on Oxygen Barrier Coating Technologies and In-Line Equipment for PP containers, for the past year. Together with Cavonic Inc. we are at the point where we can offer solutions for Oxygen Barrier for plastic containers. 

Information on Barrier Coatings:

Barrier Coating claims to be one of the most efficient processes with the highest barrier results for containers. The coating process is inline directly after the injection moulding process of the containers. A robot removes the standard PP containers out of the mould area and transfers them onto a horizontal carrier system. The carrier system drives the containers through a vacuum coating channel, where the containers are coated inside or alternativly outside by barrier materials with high barrier properties similar to glas.

This process has the biggest advantages in the operating costs as well as in the barrier properties. On the one hand the process is able to also run 32 and more cavities with 10 – 15 shots per minute and therefore is very efficient compared to the existing alternatives. On the other end the coating material is attractively cheap. Finally the process is that sustainably safe that no vision control is required, which reduces investment and scrap rate.

Test results of this new development have been encouraging. At the same time economics are better than with any other of the actual substitution technologies for cans. The process is validated in a lab scale is actually on the way for industrial application. If successful this process may have the best chances to become the breakthrough for plastic applications to substitute cans and glasses in big volumes in future.
