LimitX and Amcor Launch Commercially Available 51% LIMEX Cosmetics Bottles

LimitX Group, the exclusive distributor of LIMEX across the UK, Europe and the Gulf region, is proud to announce a major packaging breakthrough developed in collaboration with global packaging leader Amcor. Following over a year of rigorous testing, formulation trials, and technical collaboration, the teams have successfully created a new generation of extrusion blow moulded (EBM) bottles for the cosmetics sector using LIMEX, a limestone-based alternative to conventional plastic developed in Japan by LimitX’s partners, TBM.

Now commercially available through Amcor, the newly developed bottles reduce plastic content by an impressive 51%, using a formulation that blends 51% LIMEX (CaCO₃) with 49% recycled HDPE (rHDPE). An alternative variant with virgin HDPE is also available. Both options are fully exempt from the UK Plastic Packaging Tax (PPT)—offering significant regulatory and financial advantages to brands focused on sustainability.

Scalable, Sustainable, and Ready for Market

Thanks to Amcor’s global production capabilities, scaling up volumes will not be a constraint. Clients are already engaged and in discussions to integrate this solution into their product lines, marking a key milestone in sustainable packaging for the beauty and personal care sector.

Beyond plastic reduction, the solution delivers:

• Significant production efficiency: LIMEX’s thermal properties enable faster cooling by up to 50% resulting in reduced cycle times —saving energy and increasing throughput.
• A high-end, porcelain-like finish: Brands have praised the premium look and tactile quality of the bottle, describing it as “ideal for the luxury cosmetics space.”
• Reliable colour retention with rHDPE: Colour performance has proven consistent, even when using recycled polymers.
• Leak-proof assurance: The bottles have passed Amcor’s stringent quality control tests, including leak testing with existing caps and closures.

In addition, third-party brand validation has been secured. A potential cosmetics client independently tested the bottles for compatibility and stability under commercial storage conditions—with successful results after 90 days.

Sustainable Credentials and Compliance

LIMEX offers a wide range of environmental and regulatory advantages:

• Lower CO₂ footprint: By replacing fossil fuel-derived plastics with calcium carbonate—abundant, naturally occurring, and non-toxic—LIMEX supports substantial GHG emissions reductions.
• Recyclable in multiple streams: LIMEX can be recovered via closed-loop postindustrial recycling, or through standard mechanical recycling systems when detected by optical scanners in material recovery facilities.
• Compliant and compatible material with various industries including cosmetics, LIMEX requires no changes in machinery, equipment or infrastructure to be used.
• The future for LIMEX will include sourcing CaC03 through direct Carbon Capture and indirect utilisation which is already available for injection moulding and soon will be available for EBM too.

Collaboration at Its Best

The development of this solution was made possible by the combined expertise of LimitX and Amcor, supported by technical veterans such as Chris Cutts, whose 40year background in plastics played a critical role in adapting LIMEX to EBM applications.

Coordinating the cross-functional teams and managing trial oversight was Jordan Humphreys, who ensured smooth execution across formulation, testing, and validation phases.

“This launch proves sustainable innovation doesn’t require compromise,” said Omar Anwar, Managing Director from LimitX Group. “We’ve combined lower plastic content, faster production, a premium finish—and it’s ready for market.”
