500Cc Oxygen Absorber Packs - 50 Pack (5 X 10) By PackFreshUSA: Non-Toxic Food Grade For Long-Term Food Storage & Preservation With Guide Included Review

I've used PackFresh for several years. I used to throw out a bunch of smoked meats every year because they went bad over time. But ever since I started using this product, I have never thrown out any more meats. I swear by this brand.

None of these worked. I tried two different types of bags thinking it was something wrong with the first bag. No it was the Oxygen absorber. Total waste of money, time, bags and food

100% perfect every time! I've ordered these many times over the last few years, sometimes from ebay and sometimes directly from the company when ebay was out. They've been excellent every time! I even found some that had been "lost in the shuffle" here for more than a year and a half and they sealed fast just like the brand new ones. I highly recommend this company and will only buy from them! KD in IL

I have used several different kinds of oxygen absorbers. Most of them have fallen short and after a few months air is allowed back in the mylar bag. I have purchased several of these for my freezedryed food. I have not had a single bag let air in with these. They work really well. I'm so glad I found them.

Arrived in a timely manner. Used them for storing food in mylar bags. When a few hours had passed, you could see that the air had been absorbed. Very happy with purchase. Will buy these again.

They shipped and was received fast but theirs no way to find out how good they are or how well they work till I open a Mylar bag in 5 years or so and then Ill know if my food is still fresh. I do have my fingers cross. If there is a way to find out there longevity at the point of perches please let me know?

This product worked great. I packed numerous types of food products for long term storage. Almost immediately the packages began to contract as the oxygen was absorbed. I would definitely buy this item again.

All the indicators were pink when they arrived, the moment I opened it up the indicator turned purple and the absorbers started heating up.the packets were not hard but powdery.out of 12 I had two fails

I just started using these this week for storing bulk foods for long term storage. They were reasonably priced. And I love that they're ten to a pack, which is convenient for how I do about ten or twenty packs a time . because I want to limit the exposure of these to the air before I seal the mylar bags. When I had extras that I didn't want to go to waste as I was packing things away, I put them in a small mason jar and closed it up quickly, and I could tell they worked because within a few…

I appreciate your packing them in smaller packages! That is awesome since I do small batches! I'll be buying more. Thanks for attention.

Using 2, 8 oz mason jars with new rings and lids, place a 500 cc quickly in one of the jars and tighten up the lid so air cannot leak. In the other jar put nothing, but tighten up the lid also. To be sure wait 24 hours, but tapping on the lids with a wood chopstick holding the narrow end (or any substitute you feel ok using) the difference in sound will tell the story. Also you should see the center 'button' of the lid with the o2 has collapsed but not on the other jar without an o2. (You may…

The oxygen indicator is purple meaning there has been oxygen. These last few batches I’ve ordered are defective and pack fresh USA does not honor replacements even though it’s defective. Find another company that sells this exact product do not shop through pack fresh USA!

This item was cheaper directly from PackFreshUSA website, plus no taxes, plus a discount code.Good quality bags, and best Oxygen absorbers I have used. Very happy with the product.

Individual packets of 10 each is so customer friendly. I used to fret about using them all up, before they "expired", or vac. packing the unused ones, in a small jar. Now, using 10 at a time, it is so easy.Thank you, PackFreshUSA

Works right. I don't have to open a big package and risk deterioration. A 10 pack is just right for sealing a single batch in mylar bags.

These arrived two weeks after my order was placed, which is just not what I'm paying a prime membership for, but at least they were still usable once they arrived. I've seen some negative reviews stating that they were already bad when received, but mine are fine. 3 starts because it took two weeks to get them.

I'd easily buy these again. We packed rice, pasta, salt, sugar and other dry goods with these. Months later everthing was still fresh.

They come vaccum sealed in batches of ten with a small reactive dot in each pack of ten which changes color when exposed to air. Im packing dry goods in 2 liter bottles, so one 500cc pack per bottle is all i need. Very happy with the product

I like the smaller packs, that way if I don't want to do too much at one time I don't have to worry about all of my absorbers being exposed at once. 5 per pack is perfect

My order arrived sooner than stated, they were well packaged and I have already been using. I love that they are packed in smaller amounts that I can use without the worry that a large batch is losing its energy. I will certainly order from here again. Thank you!
