Mylar Comic Bags
Archival polyester — chemically stable, so the bag does nothing to the book over decades.
Here mylar means what it originally meant: polyester film free of the plasticisers and acids that migrate out of cheaper sleeves. That distinction is the entire purchase decision.

Every detail. Intentional.
Chemically stable film
No yellowing, embrittling or off-gassing.
Not PP or PVC
Cheaper sleeves migrate into the paper.
Sized by era
Current, Silver, Golden and magazine trims differ.
2 mil or 4 mil
General storage, or long-term archiving.
Boards do the bending work
The sleeve alone will not stop a flex.
Acid-free throughout
Including whatever sits behind the book.
Built like architecture.
Each Mylar Comic Bags is an engineered object — measured, dieline-cut, and hand-wrapped to spec. Below: the standard build sheet.

The full kit of capabilities.
Sizing & dieline.
Every Mylar Comic Bags is made to your fill, not pulled off a shelf. A pouch is quoted width × length — tell us what goes inside and how much of it, and we return a measured spec, free, before you commit to anything.
A pouch is sized by what goes in it, not by outside dimensions. Give us the fill weight and, if you can, the bulk — 500 g of granola needs far more bag than 500 g of powder.
We quote width × length. Flat pouches need no gusset figure — the bag lies flat when empty.
Zipper or heat seal only, valve or no valve, window or full barrier. These change the film and the bag height, so they belong in the spec rather than added afterwards.
✦ Not sure of your size? Send us the product — we measure it and build the dieline.
Pricing & minimums.
Mylar Comic Bags is priced per specification rather than from a fixed list — the same box in two different finishes can land at very different numbers. Below is what actually moves the price, so you can shape the spec before you request a quote.
The single biggest lever. Unit cost falls sharply as volume rises, because setup and tooling spread across more pieces.
Board weight and stock choice change both the raw material cost and the shipping weight of the finished run.
Foil, spot UV, embossing and soft-touch each add a pass on press. One or two lift the box; five compound the cost.
Full-bleed print inside and out costs more than a one-sided design on natural stock.
Foam, moulded pulp, velvet pillows, magnets and ribbon are priced per piece on top of the box itself.
Standard production is the base rate. Rush moves you up the production queue and carries a surcharge.
