MagniF for metal-detectable and recyclable polymers
Packaging manufacturers are under growing pressure to meet stricter safety standards while improving sustainability. For many applications, metal detectability is essential to protect consumers and brands. At the same time, packaging materials must increasingly support recycling and circular economy goals.
MagniF from LKAB Minerals has been developed to help manufacturers meet both requirements in a single, practical solution.
The challenge of metal detection
Metal-detectable packaging components are widely used in food, pharmaceutical and industrial applications. If fragments enter the production process, they must be detected and removed quickly and reliably.
Traditional approaches often rely on metallic additives or components that can create challenges, including:
- Reduced compatibility with recycling processes
- Increased material weight
- Compromised mechanical properties
- Limited flexibility in polymer design
As sustainability expectations grow, these trade-offs are becoming harder to justify.
Introducing MagniF
MagniF is a functional mineral filler designed to impart metal detectability to polymer compounds without relying on conventional metallic additives. It integrates evenly into polymer matrices, providing consistent detectability while supporting efficient processing and recyclability.
Because it is mineral-based, MagniF offers a more balanced approach to safety and sustainability.
Improving production safety
When incorporated into packaging components, MagniF allows reliable detection using standard metal detection equipment. This supports robust quality control and reduces the risk of contaminated products reaching the market.
For manufacturers, this means:
- Improved product safety
- Stronger compliance with customer and regulatory requirements
- Reduced risk of costly recalls or line stoppages
Consistent dispersion within the polymer ensures that detectability is maintained throughout the component, not just at the surface.
Supporting recyclable polymer design
Sustainability is now central to packaging development. MagniF supports recyclable polymer systems by avoiding discrete metal components that can disrupt recycling streams.
Its use can help manufacturers:
- Maintain compatibility with existing recycling processes
- Support mono-material packaging strategies
- Reduce the likelihood of rejected recyclate
This makes MagniF particularly relevant for producers aiming to align safety performance with environmental objectives.
Processing and performance benefits
MagniF is designed to integrate into standard polymer processing routes, including compounding and moulding. With appropriate formulation, it delivers metal detectability without significantly impacting mechanical performance or processing efficiency.
This allows manufacturers to enhance safety performance without major changes to production equipment or workflows.
A balanced solution for modern packaging
As packaging requirements continue to evolve, manufacturers need materials that deliver multiple benefits without compromise. MagniF offers a practical route to safer, smarter packaging – supporting metal detection, recyclability and efficient production in a single solution.
