mylar bag vacum

Post by storm.ridley »

hi;
sorry if this is repeating, but i have done my first batch of mylar bags and oxy abs all went well. but i have left them for 24 hours now and they are still not completely vacumed - are they ok like this? they arent puffy and there is less air than more if you know what i mean. any advice helpful. and if they are alright like this why use oxy abs anyway?
stay safe

Oxygen absorbers only absorb oxygen (and probably not all of it). Oxygen is only 21% of the air in the bag, so the other 79% of gases will not be absorbed, therefore you won't get the same kind of 'hard-packed' vacuum you might expect from an actual vacuum packed bag. A bit of 'puffiness' in the bag is nothing to worry about, theres no real way to ensure it's worked properly I'm afraid ;)

Sorry for delay in replying- been painting - anyhoo -

- I have found with powdered milk can leave a thin film of powder where I need to seal - so I use a clean paper towel and wipe where I am going to seal. My bags do get rock hard with powdered mil - it takes about 24hrs

- If your leaving your bags laid out overnight, you will soon know if any of your bags are punctured with the pasta & rice - because sometimes they can puncture the bags - the hole may be very small but would result in the bag not vacuuming

- oats /oatmeal doesn't get rock hard

hope this helps :)
