Premium PET cosmetic packaging: the QIUB Packaging case study

What does this case mean for cosmetic brands?

The project demonstrates that sustainability and premium aesthetics can go hand in hand. Replacing materials that are difficult to recycle with PET improves the circularity of the packaging.

From a market perspective, it makes it possible to anticipate PPWR requirements and position brands in a category where packaging innovation will be a decisive competitiveness factor.

How can AIMPLAS help you with your packaging?

If you are redesigning cosmetic packaging to make it recyclable or incorporate recycled material, at AIMPLAS we can help you validate every step: from material selection and injection moulding trials at our pilot plants to laboratory testing to confirm that the packaging protects your product.

This innovation project was funded by the Valencian Institute of Business Competitiveness and Innovation (IVACE+I), under the PIDI-CV R&D SME Support Programme 2026, co-funded by the ERDF Funds within the framework of the ERDF Programme of the Valencian Community 2021–2027.

Frequently Asked Questions

Can a transparent PET cosmetic package be manufactured by injection moulding?

Yes, although thick-wall parts require extensive process optimisation to avoid loss of transparency, residual stresses and unwanted crystallisation. This is precisely the challenge addressed by this project, with wall thicknesses of more than 5–6 mm.

Which materials are commonly used in premium cosmetic jars?

Mainly SAN, PMMA, ABS and polycarbonate, as they offer a glass-like appearance and robustness. Their main drawback is that their recyclability is limited or non-existent according to current criteria.

What does Regulation (EU) 2025/40 require of packaging?

Among other measures, that all packaging placed on the EU market is recyclable by 2030 and that the use of recycled material increases.

What are oxidative stress tests used for in cosmetic packaging?

They are used to check that the packaging does not compromise the stability or safety of the cosmetic product it contains. They are particularly relevant when the packaging material is changed.
