Grivory G 21 natural is a high viscosity amorphous PA 6I/6T (Tg 125°C) suitable for production of rigid packaging (EBM or ISBM bottles), coextrusion of tubes, coextruded blown and cast films. The key properties are high O2-barrier, outstanding transparancy, high surface gloss, high chemical resistance, very good abrasion resistance, excellent resistance to heat distortion, excellent flavour and aroma barrier. Furthermore it offers low transmission of UV-radiation with improved gas and aroma barrier at elevated relative humidity. Grivory G 21 natural is used as barrier layer food and cosmetics packaging, tubes and multilayer films of flexible meat/cheese packaging but also used as an additive for PA6 and different copolyamides to improve film properties.
