The Tightvac patented system is able to preserve goods for 1 year and beyond by allowing products to breath and degas.  Almost all food goods are smell proof inside the Vacs , however some products like freshly roasted coffee and MEDICAL HERBS may degas, leaking their odor. Our 2 way valve allows gas build up to slowly escape – without letting oxygen in. This is one of the main reasons it can preserve goods for long periods of time.

Note:  Medical herbs that are sticky & smelly we recommend using a strong zip lock bag or for a more serious situation a Reynolds oven bag inside the Vac. This helps contain the smell and keeps the area clean where the body and the cap meet. This is essential to create a smell proof situation. The sticky resin often created by these products can compromise the open and close system, causing the caps to crack when opening and closing under such pressure of a glue like substance. Keep these areas free from resin buildup. Use a product like GRUNGE OFF. Thus maximizing the efficiency of use and longevity of the Vacs.
