FlexSea is an innovative, truly compostable biopolymer material derived from seaweed and other natural, sustainably sourced products.

Proving that bioplastics do not have to be a downgrade in packaging quality or competitiveness, FlexSea’s proprietary technology allows us to create a seaweed-derived bioplastic with unseen characteristics until now.

  • Highly competitive pricing
  • Biodegrades rapidly and naturally
  • No harmful chemicals in manufacturing
  • No competition with food crops
  • No waste in production stream

Properties at a glance

1Food packaging

FlexSea is particularly suitable for the packaging of dry food items such as rice, pasta, grains, biscuits and nuts. If it is dry and traditionally comes in a flexible film packaging, FlexSea is the right alternative!

FlexSea’s excellent water vapour and oxygen barrier properties will ensure that the contents will remain safe and fresh for up to 4 months!

PROPERTIES

  • Highly efficient water vapour and oxygen barrier
  • Appropriate for dry and semi-dry foods
  • Competitive pricing
  • Printable and edible

2Dry items

FlexSea is a fantastic material for packaging any dry item, providing a tight seal from oxygen and water vapour. Its specifications are highly modifiable, meaning that any size and shape of item are within scope.

PROPERTIES

  • Water vapour and oxygen barrier
  • Customisable to product specifications
  • Competitive pricing

3Cosmetics

FlexSea is an ideal candidate for the emerging market of sustainable anhydrous cosmetics such as toothpaste bars, cosmetic powders and other sustainable dry products. The water content is removed to lower the carbon impact in their transport: that’s exactly the FlexSea spirit!

PROPERTIES

  • Water vapour and oxygen barrier
  • Customisable to product specifications
  • Competitive pricing
  • Transparent and available in a wide range of colours

Why seeweed?

We passionately believe that seaweed-derived bioplastics, such as FlexSea, are the future of bioplastics.

Exceptionally fast growth

A seaweed plant can grow up to 1 metre a day! It grows throughout the year. An entire cultivation cycle for FlexSea takes as little as 45 days – sugar cane takes over a year, and corn and beetroot many months.​

No competition with food crops

Current bioplastics compete with arable land. Starch bioplastics are most commonly made of corn, potatoes, beetroot or sugarcane. These compete with food crops and are food crops themselves. Oceans are vast sources of untapped yet sustainable resources: seaweed production is not thought to have a practical limit. ​

No freshwater required

No harm to biodiversity or habitats

The creation of arable fields for terrestrial produce destroys habitats and exacerbates deforestation.

No habitats are destroyed in the creation of seaweed farms. Seaweed farms provide stable protected areas that promote the formation of ecosystems and habitats that favour biodiversity, whilst protecting coasts from harsh waves and erosion.

No pesticides or special care required

Sugarcane, corn, beetroot, and potatoes are very chemical and labour intensive.

Seaweed is very low maintenance: it can be grown intensively in high density configurations and requires no pesticides, fertilisers or special care. It basically grows on its own, quickly and efficiently!

FLEXSEA X other solutions

Aren’t there many bioplastics already?

Where the recycling system fails to address even a significant portion of plastic waste, the most rational way to move forward with the plastic pollution issue is to explore alternative solutions.

Traditional bioplastic production results in even greater pollutant emissions than petroleum-based plastic. This is because growing the crops required to act as a base for these bioplastics have intensive growth requirements, that over-use dangerous pesticides and chemical fertilisers, depleting the soil over time and occupying valuable arable land. These crops then also need to be heavily processed with chemicals in order to turn them into usable polymers.

 

‘’Bioplastic does not mean biodegradable’’

 

Even the so called “compostable” bioplastics often require high temperature industrial composting facilities which are not widespread. They are also visibly similar to traditional plastic, meaning that consumers confuse them and throw them in the plastic recycling. However, bioplastics and traditional plastic cannot be recycled together, meaning that entire plastic recycling batches are contaminated and need to be thrown away.

FlexSea‘s use of seaweed as raw material for bioplastic production is revolutionary as it doesn’t require pesticides, fertilisers, land or freshwater, thus having a near-zero ecological and environmental impact throughout its life-cycle, whilst seaweed farming preserves ecosystems, protects coasts from erosion and sustains local economies.

“Anything is biodegradable if you think in a 1000 year span, we prefer using the terms ‘biobased’ and ‘home-compostable’.”

Why seaweed

Each existing bioplastic is deeply flawed. Bioplastics are not all truly biodegradable. The world needs us to do so much better.
