Hydropac, a specialist in cold-chain packaging, is urging industry leaders to take heed of growing concerns surrounding PFAS – per- and polyfluoroalkyl substances, often referred to as “forever chemicals.” Media reports highlighting widespread PFAS contamination in UK water supplies underscore a larger, urgent truth: material safety in packaging is not negotiable.
These long-lasting chemicals resist breakdown and can accumulate in ecosystems, affecting water sources, food chains, and ultimately human health. With thousands of water zones in England reported to have elevated PFAS levels, Hydropac warns that companies in sectors such as food delivery, pharma logistics, and temperature-sensitive transport must see this as more than a water issue, it’s a packaging wake-up call.
Chemical threats aren't the only danger
While PFAS contamination is drawing headlines, Hydropac stresses that biological contamination is a silent but significant threat - particularly from substandard cooling elements like ice packs. Many cheap alternatives on the market bypass essential microbial screening and water-treatment processes. Poor sealing, untreated water, or unhygienic production practices could lead to pathogens such as E. coli, Legionella, or Listeria entering the supply chain.
The risks? Compromised deliveries, brand damage, and in the worst cases, consumer illness.
Raising the bar on cold-chain safety
Hydropac recommends brands adopt a more rigorous approach to packaging, looking beyond mere compliance. Key features should include:
- PFAS-free materials and coatings
- Treated and microbially-tested water
- Advanced filtration and sterilisation steps
- Thoughtful design for reusability and recyclability
Why it matters more than ever
For companies in food, pharma, and other cold-chain dependent industries, the core question is evolving. It’s no longer just “Does it stay cold?”, it’s now:
- Was this cooling product made with safe, tested materials?
- Has the production water been treated and verified?
- Could this component become the weak link in our safety chain?
- Are we prepared for the regulatory, reputational, and consumer impact if something goes wrong?
While budget options may seem attractive short-term, peace of mind - for compliance, brand integrity, and consumer safety - is proving priceless.
Pushing for higher industry standards
With UK regulators increasing scrutiny of PFAS and similar risks, Hydropac calls on the entire cold-chain sector to raise the bar - not just in thermal performance but in full-spectrum material and hygiene safety.
“Environmental safety doesn’t begin at the water plant - it starts at the design table. Every choice counts,” said Francisco Azeredo, Commercial Manager at Hydropac.
“Function isn’t enough anymore. Brands must challenge their suppliers and ensure every part of their cold-chain is as safe as it is effective,” he added.
