Coatings Offer High Barriers

Nanolok WR water-based barrier coatings offer high-oxygen barrier over the widest relative humidity and provide similar moisture barrier to that of PVDC-coated PET when tested at 85RH and 40 deg C, company says. Coating also provides a new level of direct adhesion to a wide variety of flexible packaging films, including many polyolefins, enabling customers to reduce the number of layers in their barrier packaging. After drying, this coating has shown excellent resistance to incidental contact with water and will maintain its barrier properties after top coating and/or application of water-based inks.
