Alternatives for packaging with PVDC tested on beef

17 January 2017

Researchers at DuPont Packaging & Industrial Polymers in Brazil evaluated the potential of using non-irradiated barrier-shrink bags containing ethylene-vinyl alcohol copolymer (EVOH), polyamide (PA) and ethylene ionomer in their structures to preserve vacuum-packaged fresh beef as an alternative to traditional gamma-ray cross-linked bags containing polyvinylidene chloride (PVDC). Beef was vacuum-packed using EVOH 44% mol, EVOH 32% mol and a control PVDC barrier shrink bag.
They found that the EVOH 32% mol non-irradiated and chlorine-free film is as effective for the preservation of fresh beef as traditional PVDC-irradiated shrink bags. An article about the research is published in Meat Science.
