Glass-clear PET with Oxygen Scavenging.
Mullinix showcased its innovative, glass-clear, PET/scavenger packaging – maintaining zero oxygen permeation for over four years – at the recent Pack Expo Las Vegas exhibition. The company says the container performs better than metal cans or glass to prevent oxidation of foods and beverages and is ideal for convenience of prepared foods. 
The contents can be seen by consumers and product flavour and consistency is not degraded over time by the packaging material performance. The OxyRx™ material enhances traditional PP/EVOH packaging used since the 1980’s and can be thermoformed into stock or custom shapes as well as lidded with film or foil.
The material can also be crystallized into CPET packaging for retort applications and heating in both microwave and conventional ovens up to 400 degrees. Traditionally, packaging comprised of oxygen-scavenging materials costs more. Because of its efficacy, the new OxyRx™ PET/scavenger material is competitive with many of the commercial PP/EVOH containers and may offer cost savings for higher EVOH percentage applications, claims Mullinix. Advantages of the OxyRx™ containers include better flavour, odour, shelf life and overall performance. The material used can be recycled with most other PET.
