ProAmpac has launched its fibre-based Modified Atmosphere Packaging (MAP) RAP Sandwich Wedge to the North American market. Designed for sandwiches and wraps, the package introduces the concept of modified atmosphere packaging to a fibre-based format. ProAmpac’s RAP Sandwich wedge is said to have the capability to keep a fresh sandwich or wrap preserved for up to 28 days. It incorporates a carton board structure with a thin film lining to optimise product preservation and visibility. Irma Randles, ProAmpac's market manager for fresh food-to-go, said: "Sustainability lies at the heart of ProAmpac's business strategy and we are thrilled to unveil the fibre-based MAP RAP Sandwich Wedge. Our packaging solution represents a more sustainable alternative to conventional plastic sandwich packs while reducing food spoilage costs. “ The wedge utilises high barrier technology to extend product shelf-life, especially when incorporated with gas-flush filling technology. The RAP Sandwich wedge is said to enable longer transit and selling time, enhancing sales potential while minimising food waste.
