Mylar bags · Packaging buyer’s guide
A barrier requirement should describe what the product needs protection from and for how long under specified conditions. The words foil, metallized, or Mylar are not a complete performance specification.
The short answer
Define the relevant barrier properties and conditions in the project specification. A metallized appearance, film thickness, or marketing term does not establish a product’s shelf life. Review material documentation, seals, and product validation together.
What to review before approving production
Ask for the proposed film construction and relevant test information. Evaluate the formed package, including seals and any opening features, as part of the protection system. The brand should establish shelf-life claims through appropriate product and package validation.
