Unutilized packs can be placed in a mason jar or re-sealed to minimize waste during non-use. Oxygen absorbers, surpassing vacuum sealing in oxygen removal, can prolong shelf life. Ideal for various storage containers like mylar bags, vacuum bags, and mason jars. When heat sealing both food and non-food items, employ oxygen absorbers to eliminate oxygen from sealed vacuum bags. Suitable for preserving items like rice, pasta, beans, oatmeal, coffee, jerky, nuts, dried meats, and flour. Also vintage items, collectibles, and possessions. Each oxygen absorber package includes an oxygen indicator. The indicator, pink when properly sealed, may display varying shades from bright pink to reddish when sealed correctly, signifying the absence of oxygen. Once opened, the indicator transitions to blue. › See more product details
