Know before you buy
These absorbers are specifically designed for use with Mylar bags. They are not recommended for use in glass jars or rigid plastic containers, as those materials can be damaged by the vacuum pressure created during the oxygen absorption process.
Since the outer packaging is not resealable, you must store any unused absorbers in an airtight container, such as a small Mason jar or a vacuum-sealed bag, immediately after opening. If they are exposed to air for too long, they will activate and lose their effectiveness.
No, a vacuum sealer is not required. The oxygen absorbers will naturally remove the oxygen from the sealed Mylar bag, creating a vacuum effect on their own.
These absorbers have a shelf life of one year from the date of manufacture. It is best to use them within this timeframe to ensure they maintain their full absorption capacity.
Yes, the iron powder is contained within a food-safe Mylar pouch. The pouch is designed to allow oxygen to pass through while keeping the contents securely inside, so they can be placed directly in contact with your food items.
