Why this one
The mylar bag category has a lot of soft material being sold as mylar. Real mylar is a specific polyester film, and the aluminum middle layer needs to be a real metal barrier. We source from a maker that meets the spec, and we test every run.

What people use it for
“Use these for long-term grain storage. Oxygen absorbers and a heat sealer and they last for years.”
“Great for packaging my small-batch granola for the farmers’ market.”
“Lightweight enough for shipping but tough enough they do not tear in the mail.”
Common questions
Do I need oxygen absorbers?
For long-term dry storage (more than a few months), yes. The mylar blocks oxygen migration but does not remove the oxygen already inside. An absorber inside the bag does that job. We sell them as an add-on or you can source separately.
What seals these?
A standard impulse heat sealer at 4 to 6 seconds on most models. The zip-lock works for daily-access bags without sealing.
Are these recyclable?
The film is a composite, which makes most curbside recycling impossible. Specialty mylar recycling programs accept them in some regions. For most users, mylar is reusable several times before disposal.
