Our machine has 1 12 months guarantee and our machine's cam/splitter/air distributor has lifestyle circle guarantee. The three most favored MAP approaches are fuel flushing, barrier films, and scavenger or desiccant packaging. The machine seals the packaging right away to ensure oxygen doesn’t reenter the bottle or blister pack. https://www.linpack.com/products-tray-sealing-machine-ta350-360
