A developed plant-based protective coating

Israeli company Melodea launches MelOx™, a high-performance plant-based protective coating that protects packaged products from the transfer of oxygen and oil and grease. And VBcoat™ which protects packaged products from water vapor and oil and grease transfer.

The company derives its raw material base from cellulose, which is an abundant biopolymer and is recognized by AIPIA (Active and Intelligent Packaging Industry Association) as a potential base for antimicrobial/antibacterial packaging films.

Technology creates cellulose nanocrystals (CNC) that give power to plants and can be used as a basic element for the improvement of existing materials and for the production of new ecological materials.

Food packaging solution

The company obtains its packaging coating material entirely from plant materials, and the coatings can be recycled.

In addition, it applies patented technology for the production of materials, for example, from wood pulp from trees grown in industrial forests. These water-based products can be applied as a coating various substrates, on:

  • Paper
  • Card
  • Bioplastics
  • Monoplasty

High barrier coatings can be adapted to a wide range of packaging formats, such as pouches, lids and molded pulp products, such as trays and plates for short and long storage.

barrier coating

Protective coatings can be divided into two broad categories:

  • A water-based coating usually cures at room temperature. It is generally non-hazardous and low-flammability, which makes it easy to transport and handle. The water base makes cleaning easier.
  • Powder coating is usually dried at a controlled high temperature. It is used to create the surfaces of many white appliances, such as washing machines, dryers, refrigerators, etc.

These solutions are regularly applied to metals and ceramics when they cannot withstand very difficult working conditions. Many industrial processes take place at very high temperatures under the flow of aggressive and corrosive gases.

Metals can often corrode, which can lead to catastrophic failure during operation. To prevent this and improve their lifetime and performance, metal and ceramic components are coated with a different material that can withstand these demanding environments.

Finally, with a focus on sustainability, the products that the Israeli company innovates have the necessary regulatory approvals and sustainability certificates and are completely non-toxic to humans and the environment, as well as PFAS-free.
