The use of oxygen absorbents in plastic bottles to increase the shelf life of packaged foods is rapidly increasing. Valspar has developed Valor's range of thermoplastic oxygen absorbing materials for single-layer PET bottles and multi-layer barrier PET bottles. . Valor's application targets are fruit juice, beer and other beverage bottles. Its outstanding advantages are that it only activates when exposed to moisture, and it improves the delamination resistance of multi-layer PET bottles and prevents delamination of multi-layer bottles, resulting in significant barrier effects. Better than packaging with special nylon MXD6. Valor maintains its good oxygen absorption properties at relatively high temperatures (32°C) and humid conditions (relative humidity RH of 90%). Valor currently has 3 grades, of which 1 is for single-layer bottles and 2 for multi-layer PET bottles, packaging CSD (carbonated soft drinks) and beer.
