Why should you switch from polystyrene fish boxes 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 EPS or polystyrene fish boxes.

Coolseal is the industry leading alternative to help solve the polystyrene problem. Not only does Coolseal offer all the same performance characteristics as polystyrene fish boxes, but has a whole host of additional benefits for the seafood sector too:

Store up to 80% more packaging

Due to the flat-pack design of Coolseal fish packaging, storage space can be freed up when compared to bulky EPS polystyrene fish box counterparts. With 8-% more boxes per pallet, you will receive fewer inbound packaging deliveries, and can free up valuable storage space that could even allow for production expansion.

Ship 30% more product per pallet

Coolseal seafood packaging isn’t as bulky as EPS polystyrene fish packaging, which allows for a much greater amount of product per pallet. In fact, Coolseal boxes allow for 30% more fish on a single pallet. This translates to less outbound deliveries needed and a potential big reduction in your transport costs.

Low cost seafood and fish packaging

Polystyrene has always been a low-cost material – making it perfect for manufacturing fish boxes with. With a shift in the cost of raw materials, and polystyrene being an energy intensive material to make, Coolseal fish boxes now provide a more cost-effective solution.

Patented sealed edge technology

The fluted edges of Coolseal seafood packaging boxes are uniquely sealed; not only creating excellent insulation and strength properties, but removing the risk of contamination as well. In addition, Coolseal boxes are safe for food use, waterproof and don’t absorb the smell that polystyrene fish boxes can.

Helping the fishing industry reduce its carbon footprint

Sustainability is a critical factor when it comes to packaging. With an ever greater need to look at carbon cutting options, Coolseal fish boxes enable you to significantly move more product per pallet – cutting the amount of transport needed to move fish through the cold chain, cutting CO2.

Branded fish and seafood packaging

Printing options for polystyrene fish boxes are limited due to thenature of the box design. Coolseal however, uses screen printing which provides the possibility of multi-colour photgraphic images to be printed on any or all sides of the box. Therefore allowing for maximum brand exposure.
