LyondellBasell selected Norner to evaluate their latest recycled PP materials in Caps&Closures.
We evaluated the recycled materials in various end applications. One important segment is caps for household chemicals, cosmetics and personal care containers.
The joint venture between LyondellBasell and Suez, established in The Netherlands, has introduced a set of recycled Polypropylene and Polyethylene’s to the market. This joint venture – QCP – has teamed up with the innovation/R&D centre of LyondellBasell in Ferrara-Italy for tailoring their recycled materials for important end markets.
Norner has been assigned by LyondellBasell in Ferrara to evaluate the recycled materials in various end applications. One important segment was caps for household chemicals, cosmetics and personal care containers.
Recycled PP in flip-top cap end use
Norner operate a 4 cavity flip-top cap mould with very important features for the market that can be evaluated. This includes:
Integrated hinge performance (Cyclic test)
Response to colour MB
We carried out trials with Moplen QCP300P and Moplen QCP540S and tested them with a Moplen hompolymer mfr 15 as a reference.
Processing of the materials by injection moulding was very good and showed consistent and reliable operation.
Emanuele Burgin - Application Development, Technical Service and Innovation manager PP Europe, Rigid Packaging and Caps and Closures says “Very interesting and positive results for our recycled PP produced by our Joint Venture QCP”.
The summary of results are showed in the table and clearly demonstrate that the tested materials process very well and achieve very good mechanical strength. The caps also looks very good and has good dimensional stability.
These samples shows the white colour achieved with increased loading of white masterbatch.
