Metalchemy embeds a natural silver additive into packaging, killing 600+ pathogens and extending shelf life - without altering products or using toxic chemicals.
About
Today’s corporate supply chains face growing pressure to cut toxic chemicals, reduce waste, and protect both people and nature - yet most products still rely on synthetic petrochemical preservatives that harm ecosystems and are increasingly restricted by regulators. This creates a critical challenge: how can we ensure product safety without compromising sustainability?
Metalchemy has developed a breakthrough solution. Our patented sustainable silver-based additive, produced using plant extracts, transforms the packaging itself into an active antimicrobial barrier, neutralising over 600 pathogens (including resistant strains) on contact. Instead of adding harmful preservatives inside the product, our additive builds protection directly into the packaging, stopping microbial contamination at the interface.
Unlike conventional preservatives, our approach is toxic-free, circular by design, and supply chain ready. We eliminate the need for synthetic petrochemicals like Methylisothiazolinone or Benzyl Alcohol, and our natural plant extracts can be sourced from agro-industrial waste - turning by-products into value. This allows companies to reduce their chemical footprint, meet tightening regulations, and align with their corporate sustainability and nature-positive goals.
In short, Metalchemy enables safer, cleaner, and more sustainable products across global supply chains - without the use of toxic chemicals.
Key Benefits
By embedding Metalchemy’s silver-based additive directly into their packaging, companies can achieve powerful antimicrobial protection without changing their product formulations or relying on synthetic chemical preservatives. This built-in barrier actively neutralises over 600 pathogens, including resistant strains, to keep products protected from the moment they’re packaged until they reach the end consumer.
For manufacturers and brand owners, this means more than just safer products: it enables clean-label offerings that appeal to health- and sustainability-conscious consumers, longer distribution windows that open access to distant markets, and dramatically fewer returns or losses from spoilage. By cutting the need for petrochemical preservatives, companies can reduce their chemical footprint, strengthen compliance with tightening regulations, and position themselves as leaders in sustainable innovation.
At Metalchemy we turn packaging into a powerful asset , transforming it from a passive container into an active shield , helping businesses reduce waste, protect margins, and build consumer trust while advancing their sustainability goals.
Applications
Metalchemy’s innovation is designed for food and beverage manufacturers, packaging producers, and FMCG brands seeking to enhance product safety and sustainability without changing their existing formulations. This includes beverage and food producers, and other perishable goods, as well as packaging suppliers serving these high-volume sectors, who are under growing pressure to reduce waste, extend shelf life, cut chemical use, and deliver on ambitious sustainability commitments.
These industries operate in massive and fast-evolving markets. The antimicrobial packaging sector alone is projected to reach $12.73 billion, while the broader food and beverage packaging market exceeds $346 billion. As companies increasingly seek cost-effective, scalable alternatives to synthetic chemical preservatives, Metalchemy is positioned to become a leading enabler of circular, silver-embedded sustainable packaging technologies across global supply chains.
