According to reports, Va1OR is a series of new barrier/deoxidizer resin products. The use of ValOR bottles can extend the shelf life of beer, and thus provide a basis for brewers to use large-capacity plastic beer bottles. Va1OR resin is a proprietary polyester that is not easily layered compared to other barrier resins that are often used in multilayer PET constructions.
In an interview, Adam Sarson, general manager of Wazbul said: "This is a response to the current market demand." The company has applied the resin to the limited commercial production of film and paperboard. In addition, Nature Works LLC will report on the results of its in-depth investigations on improving the barrier properties of PLA bottles. According to a press release, PLA is challenging PET in applications such as milk beverages, fruit juices, and water because oxygen barriers do not pose a problem in these applications.
The company, headquartered in B1air, Nebraska, is working with its partners to position PLA bottles for extended shelf life applications. Company officials said there are several technical solutions that can be applied to PLA bottles to improve barrier performance. These programs include multilayer structures, coatings and additives.
