Ultrahigh Barrier Coating Breakthrough From InMat®

Thursday, 07 May 2009

Hillsborough, New Jersey, May 7, 2009. InMat®, the leader in environmentally friendly, high barrier nanocomposite coatings, announces its new Nanolok™ PT ADV-7 water-based coating formulation providing a more sustainable, cost effective option for transparent, high oxygen and/or 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, EVOH. Coating thicknesses in the range of 0.5-0.8 micron provide better oxygen barrier than 10-20 microns of EVOH, and provide much better oxygen and moisture barrier 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 ft/minute have already been achieved.

Nanolok™ PT coatings do not contain halogens, VOC’s, or other hazardous materials and are compliant with food contact regulations in the US and Europe. Alternative barrier materials such as EVOH and PVDC negatively impact the ability of packaging material to be recycled. 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." says 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."

Samples of coating formulation and coated packaging film (48 gauge PET) are immediately available and can be purchased for evaluation.
