Why should you switch your seafood packaging to Coolseal?
Polystyrene is a huge problem when it comes to marine pollution. For an industry that relies on the marine environment the fishing industry needs a more sustainable fish packaging alternative to polystyrene fish boxes.
Coolseal is the industry leading alternative to help solve the polystyrene problem. Made from 100% recyclable material, Coolseal fish & seafood packaging is made from polypropylene – a more sustainable and environmentally friendly material than polystyrene. Aside from being a more sustainable option, Coolseal seafood packaging offers a whole host of benefits for those in the seafood industry…
