A Grimsby Collaboration for a Sustainable Future
The Coolseal team had the pleasure of visiting Jaines
Seafood – a proud Grimsby-based business with a long-standing reputation for
quality fresh fish and seafood.
As two companies rooted in the heart of the UK’s seafood industry, it was great to see our shared values in action – particularly when it comes to innovation and sustainability.
Jaines Seafood has been using Coolseal’s polypropylene packaging for some time now, and their commitment to quality and the environment makes them an ideal customer. Our visit was a fantastic opportunity to see our sustainable packaging solutions at work – keeping seafood fresh while significantly reducing environmental impact.

Traditional polystyrene (poly) boxes, long used across the industry, are increasingly being recognised as outdated. Not only are they difficult to recycle, but they often end up in landfill or worse, in our oceans. In contrast, Coolseal’s polypropylene packaging is 100% recyclable, lightweight, durable, and resistant to water – making it ideal for seafood logistics without compromising on environmental responsibility.
It’s inspiring to see fellow Grimsby businesses like Jaines leading the way in adopting smarter, greener solutions.
Together, we’re helping reshape the seafood industry from right here in Grimsby – proving that sustainability and performance can go hand in hand.
But Coolseal seafood packaging distribution doesn't stop there!
We distribute our industry leading seafood packaging across Europe and beyond.
With ever-growing interest in our seafood packaging, there’s an ocean of reasons to make the change from poly or lined cardboard boxes to a sustainable and future-thinking alternative in Coolseal.
Coolseal sustainable seafood packaging is vital for all seafood businesses due to its combination of environmental responsibility, operational efficiency, and product integrity. Crafted from 100% recyclable polypropylene, Coolseal boxes serve as a superior alternative to traditional polystyrene fish boxes, which are notorious for contributing to marine pollution.
Additionally, Coolseal’s flat-packed structure allows for up to 80% more efficient storage and enables transporting up to 30% more product per pallet, leading to significant reductions in storage and transportation costs!
