GLOBAL PACKAGING OUTLOOK
Global packaging is changing.
From material selection to end-of-life management, a changing market calls for both new material possibilities and product-level validation.
Market and policy research as of October 30, 2026
Designing for recycling and resource efficiency
The EU Packaging and Packaging Waste Regulation (PPWR) began general application in August 2026. Its phased requirements for recyclability, recycled content and packaging reduction increase the importance of material selection and container design.
European Commission · PPWRBrands are seeking to use less virgin plastic
L’Oréal aims to reduce virgin plastic use in product packaging by 50% by 2030 compared with 2019. Its work on refills, recycled materials and alternative materials illustrates a wider direction in the beauty industry.
L’Oréal · Circularity ambitionsConsidering packaging beyond its use
California’s SB 54 strengthens packaging reduction, recycling and producer responsibility. Product design that considers collection and recycling is becoming increasingly important alongside material performance.

FROM POTENTIAL TO APPLICATION
Assessing potential at the product level
Materials that make use of shell resources can offer another packaging option. Their competitiveness needs to be assessed through plastic use per functionally equivalent container, performance, lifecycle carbon emissions and recyclability.
Shell content is different from recycled plastic content. Mineral fillers can affect PP density and recycling processes, so the final container’s formulation and design require assessment.
RecyClass · PP container design guidelinesView our US container testing progressTariffs, packaging taxes and material selection
Using shells does not automatically reduce tariffs or packaging taxes. Import duties depend on factors such as product classification and origin. The EU CBAM currently covers specified goods such as iron and steel, aluminium and cement; a CBAM saving from using shells in ordinary plastic cosmetics containers has not been established.
For the UK Plastic Packaging Tax, additives such as calcium count as part of the plastic. Assessment requires the relevant national rules and actual product composition; any cost effects from future policy changes need separate review.
