Ultrahigh Barrier Coating Reduces Food Packaging Costs

HILLSBOROUGH, NJ - Nanolok™ PT ADV-7 water-based coating formulation, a new product from InMat®, provides a more sustainable, cost-effective option for transparent, high-oxygen and moisture-barrier food packaging. By reducing the amount of barrier material needed and using only non-hazardous materials, this technology enables food companies to produce long shelf life products with reduced carbon footprint and environmental impact.
Nanolok PT ADV-7 reduces both material and process costs when compared with the lowest cost transparent high-oxygen-barrier material. Coating thicknesses in the range of 0.5-0.8 micron provide a better oxygen barrier and provide much better oxygen and moisture barriers when compared with PVDC-coated PET. These transparent coatings can be applied using commercial roll coating equipment while providing performance competitive with more expensive vacuum and plasma deposited coatings. Coatings speeds of up to 900 feet per minute have already been achieved.
Nanolok PT coatings do not contain halogens, VOCs or other hazardous materials and are compliant with food contact regulations in the United States and Europe. The very small amount of Nanolok barrier material needed to achieve the required shelf life will improve the recyclability of barrier packaging. Nanolok technology will also reduce the total amount of material sent to landfills. In addition, Nanolok PT ADV-7-coated bio-derived polymer films meet compostibility standards.
“What is unique is that our Nanolok coatings can be applied at low thickness and high speed, using standard roll coating equipment while achieving high barrier levels at lower cost." said InMat CEO Harris Goldberg. “This provides new options for film producers, converters and end users to design and produce more sustainable, cost-effective, high-barrier packaging.”
Since 1999, InMat Inc., The Innovative Nanocomposite Materials Co., has led the development and commercialization of nanocomposite barrier coating technology. The company is committed to providing environmentally friendly coatings to improve product performance for both industrial and consumer product applications.
