Global challenges have inspired us to step up and take the lead in moving our industry forward to a more sustainable future.

Results: ECOLogic

Liquidseal’s coatings have a proven track record of outperforming control groups as well as conventional coatings like wax. Citrus coated with our eco-friendly formula consistently retain a more constant quality and increased firmness, while still being able to enter their ripened stage. Results show better looking citrus that are less susceptible to contaminants like mold, as well as a significant reduction in weight loss.


Using Liquidseal cuts out wasteful expenses like overproduction to make up for losses and the harmful chemicals used to prevent them. Citrus can also be stored for longer, allowing for greater flexibility in responding to fluctuations in supply and demand. By removing the need to re-grade and re-sort upon arrival, Liquidseal is not only more effective but also more efficient.

Specially formulated coatings are used for citrus such as oranges, mandarins, limes and grapefruits to improve quality and prolong shelf-life.

How it works

Liquidseal is a post harvest coating which achieves shelf-life extension of perishable products such as fruits and vegetables. Liquidseal preserves product quality and freshness from grower to customer.


Effective barrier:

  • reduces evaporation
  • slow release system
  • controls gas exchange

Application, Post Harvest Handling, and Implementation

Liquidseal’s coatings can be easily applied in various ways and seamlessly integrated into existing production lines. Whether applied immediately after harvesting or during post harvest handling, our coatings ensure 100% coverage, providing security to citrus at different ripening stages.


This flexibility makes Liquidseal the ideal choice for growers and importers, offering a low-cost solution across the supply chain.
