    One Quart 3.5 Mil Seal Top Mylar® Bags with PackFreshUSA LTFS Guide

    • New “Bottom-Filling” bags are tamper evident and easier to seal!
    • Other brands require you to seal in a very narrow area next to the Seal Top
    • Our same Top-Rated FDA approved Mylar® Bags with added Seal Top
    • Easily seals with a FoodSaver, iron, or hair-straightening iron
    • *BE AWARE: ALL Mylar bags MUST be heat-sealed for food storage. A re-closure seal is only for resealing food after you open it.
    • Rounded corners protect your other stored items from puncture or damage.


    Why use a Seal Top?

    You will appreciate the convenience when it comes time to open it! ALL Mylar bags MUST be heat-sealed for long-term food storage, but Seal Top bags are a handy way to reseal your food when it comes time to open it.

    Why is the Seal Top on the bottom?

    This is the way commercial product packaging is made. First, you don’t want to have to heat-seal in a narrow area next to the reseal top. Second, the result is much cleaner and easier to open and reseal.


    “If an earthquake, hurricane, winter storm, or other disaster strikes your community, you might not have access to food, water, and electricity for days or even weeks” - FEMA

    Although 4 out of 5 Americans live in counties that have been declared federal disaster areas, 53 percent do not have a 3-day supply of nonperishable food at home.

    It doesn’t have to be this way...

    You do not have to purchase expensive emergency food! Sealing food using Mylar bags and oxygen absorbers (Sold separately) protects it from mold, bugs, and oxidation for over 25 years.

    Things to consider:

    Buy from a reputable manufacturer. Importers who buy “mylar bags” off of Alibaba often don’t realize those bags are PET, which is not Mylar as claimed. They are thick and cheap, taking advantage of the common feeling that thicker must be better. It is the quality of metalization that keeps oxygen out, not PET.

    Only store food that does not need refrigeration. Buy the best oxygen barrier and use a plastic bucket or container for extra physical protection. Use extra absorption to lengthen storage time. Unused oxygen absorbers may be stored in a mason jar or vacuum sealed. All Mylar bags must be heat-sealed, which is easily done with a household iron or hair-straightening iron.

    1. Great value and easy to use with bottom fill  star rating

      Posted by Randolph Haack on Jan 4th 2022

      I really like this product. The bags are not so thick so when I vacuum pack and use OAP in bags, they lay much flatter than the Amazon zip bags I used before. These are lower cost and larger in size for a quart bag than the Amazon obtained version. The bottom fill is so much handier too since I do not have to struggle to open each zip lock to insert product. Sealing with chamber vacuum, impulse sealer and hair straightener all works perfectly.
      I purchased 400 to test the product line and now I need to order some other sizes.
