Peak Fresh Preserving Bags work by: Removing ethylene gas - most fruit and vegetables release ethylene gas after harvest. Exposure of the produce to the gas accelerates aging and ultimate deterioration. Peakfresh Preserving Bags remove ethylene gas to prolong the life and freshness of the produce. Unlike ordinary plastic bags, Peakfresh Preserving Bags 'breathe' so that damaging gases produced by the fresh produce are removed.

Peak Fresh bags minimise moisture formation through the anti-fogging treatment of the film surface. This minimises moisture formation to inhibit bacteria growth. They also maintaining Vitamin C levels.

Peakfresh Preserving Bags are certified by NASAA (National Association of Sustainable Agriculture Australia) and Biological Farmers of Australia for the packaging of Level A organic produce. Accredited to the International Federation of Organic Agricultural Movements (IFOAM). Peakfresh Preserving Bags are manufactured in Australia.
