Vacuum Packaging Material

Vacuum pouches are usually multi-layered nylon and polyethylene. All plastic materials has an oxygen transfer rate (OTR). The OTR of the pouch you use for long term storage is important because the longer the product stays oxygen free, the longer it will last. As the environment is kept anaerobic for a longer period of time. Some pouches has added materials to increase the effectiveness of the barrier. Commercial products such as smoked beef jerky uses such pouches.
