Dovy Segev, CEO of Valentis, describes how the company’s nanocrystalline cellulose-based formulation (NCC) improves polymeric films.

The Need

Thermoplastic films are everywhere from food packaging and agriculture to defense. To meet the demand for new products and greater functionality, layers are added to the film, which makes them thick and heavy, and increases the cost; however, manufacturers are always looking for ways to make it thinner and cheaper. High-barrier food packages, for example, integrate multiple layers – including one of aluminum foil — to prevent food deterioration due to oxidation, moisture, and UV penetration. Manufacturers of thermoplastic greenhouses add layers and ingredients that block infrared (IR) light from escaping to optimize growing conditions.

The market need and opportunity for improved thermoplastic films — thinner, stronger, greener — with added functionality is tremendous.

The Technology

The technology developed by Valentis Nanotech combines nanocrystalline cellulose (NCC), a biodegradable, transparent material made from plant pulp waste, with additional nanoparticles to produce highly improved polymeric films.

Embedding different nanoparticles into Valentis’ composites adds new functionality (for example, piezoelectric or antibacterial properties) that can be tailored to specific applications and needs.

The Company’s first product is a coating for use in the food industry to create packaging material that is thinner, transparent, stronger, and provides a high barrier against UV rays, oxygen, and moisture.

The Advantages

  • Super strong: Strength-to-weight ratio 8x greater than stainless steel
  • Thin and lightweight: Reduces packing, transport, storage costs
  • Friendly: Produced from plant pulp, safe and biodegradable
  • Functional: Transparency, better oxygen barrier, spectral control (UV, IR)
  • Customizable: Tailored to specific requirements
  • Cost-effective

  • Prof. Yossi Paltiel, Inventor: Hebrew University of Jerusalem, Center for Nanoscience and Nanotechnology; research focus: quantum nanostructures

The Market

NCC is coming into focus as a material of the future, projected to create a $600 billion industry by 2020 (U.S. National Science Foundation). The Valentis technology has enormous potential in multibillion-dollar markets, including food packaging, agriculture sheeting, antibacterial packaging, defense, home and garden, and transportation.
