InMat® Inc : High-barrier transparent nanocomposite coatings
InMat’s environmentally-friendly, water-based barrier coatings contain no solvents or hazardous materials, are appropriate for food packaging applications, and can be applied to PET film via roll coating, spray or dip processes.
Said to exceed properties of conventional barrier packaging at lower cost, the large number of water-based coatings include: Nanolok PT ADV-7 which provides oxygen barrier up to 80% RH while also providing improvements in moisture barrier; Nanolok PT ADV-E, which costs 30% less than ADV-7; Nanolok EXC, which costs 50-60% less than Nanolok PT ADV-7 while still providing similar levels of oxygen barrier up to 65% RH; and Nanolok WR 301409, which provides good oxygen barrier up to 80% RH, moisture barrier similar to Nanolok PT ADV-7, superior adhesion to several polymer films eliminating the need for a primer on BOPP and PLA, and twice the solid content of InMat’s other formulations (14% vs. 7%) reducing the required drying time and enabling a higher speed, lower cost, coating process. Additional coatings are available.
