    1. 10-packs are the best  star rating

      Posted by Becky on Nov 25th 2021

      I like the 10-packs that this company sells. I freeze dry small food packages for camping, travel, and emergencies. Working with smaller 10-packs makes it much easier for me to keep the oxygen absorbers fresh, and use only what I need. I will continue to place orders with PackFreshUSA because they offer the size, quantity, and price I need.

    2. I like these OA's a lot !  star rating

      Posted by Unknown on Oct 13th 2021

      Great product for all kinds of uses, but especially for freeze dried items.
      This size is especially useful for tucking into a quart size mylar bag or even
      a quart canning jar to keep everything air-tight. I especially like the ten packs with the indicator to know these are fresh.

    3. Good price, excellent service  star rating

      Posted by Donna on Jan 6th 2021

      PackFreshUSA is our go-to for all mylar and OA's. The ten packs are perfect for our purposes and the pricing is very good. Best service from this company. Products are reliable and shipping is great.

    4. Fast delivery  star rating

      Posted by Rod on Dec 24th 2020

      PackFreshUSA delivers. I buy these in 10 packs because they are easier to seal back up after I open them for my freeze dry bags of 4. The price is close to the large bags but I feel this way doesn't expose the whole bag each time. Thanks for the great product and service.

    5. Great for Mason/Canning Jar Storage!  star rating

      Posted by Doc on Dec 11th 2020

      We use these to extend shelf life of cereals, flours, etc in large Mason/canning jars and they work great! There is no extraneous smell or taste and they certainly do the job. Also reasonably priced enough for budget minded families to use as the money saved outweighs the cost of item(s) which is great! Also, during the busiest holiday shipping season of a terrible year the shipping and delivery were crazy fast! Thanks for the great work getting them out and for a great product overall!

    6. Better Than Expected  star rating

      Posted by Unknown on Oct 22nd 2020

      Well first off, the team at PackFresh went above and beyond the call of duty in making sure my order came in a manner that exceeded my expectations. The customer service, and commitment are what service is all about.

      The prodcuct i ordered, the 300cc packets worked as advertised.
      I use these with vacuum sealed products, and the color accuracy after my testing is accurate. I will be ordering these again as they are perfect size for pint and quart sized bags.

      Thansk again!!!

    7. The best there is!  star rating

      Posted by Catherine Adlerhurst on Mar 29th 2020

      Excellent Product as well as Excellent Company. Excellent Customer Service. That's 3 Excellents! I Will be ordering more.

    8. Solid Product  star rating

      Posted by Unknown on Sep 12th 2019

      My recent order of 300cc oxygen absorbers arrived in good time. I've already mowed through several packs, and the quality is great. PackFreshUSA is a name I'm beginning to really trust.

    9. Never a fail with these!  star rating

      Posted by De Paschen on May 23rd 2019

      I have used other absorbers and have had problems but PackFresh never a fail. Third time buying from them.

    10. Very Impressed With This Company  star rating

      Posted by Unknown on Mar 22nd 2019

      I have ordered these products from other companies in the past, both no one else has provided the detailed information needed to properly use the absorbers and seal the bags. I am very happy I found this company and will order from them again.
