Anyone who has handled comics for a while knows the difference between good storage and just “something to put them in.” Mylar doesn’t sag, doesn’t yellow, and doesn’t trap moisture the same way low-grade plastics do.

Anyone who has handled comics for a while knows the difference between good storage and just “something to put them in.” Mylar doesn’t sag, doesn’t yellow, and doesn’t trap moisture the same way low-grade plastics do. That’s why collectors, comic shops, and grading services prefer it.
With our custom mylar comic bags, you get a protective sleeve that stays rigid, keeps colours bright, and shields pages from the air and oils that wear them down. Whether you’re storing key issues, selling new releases, or archiving back-issues, these sleeves give your books a stable home.
We also offer graded comic mylar bags, resealable options, and heat-seal compatible mylar bags for long-term archiving.
Not all sleeves are equal. Many basic polypropylene or poly bags bend over time, trap humidity, or start sticking to covers if the environment gets warm. That’s where mylar shows its strength.
Here’s what makes it work:
If you’re selling online, mylar sleeves also help keep books presentable during shipping. Customers see a clean, sharp presentation before they even flip a page.
Collectors deal with different formats, and we build bags with that in mind. Our custom mylar comic bags can be produced for:
Whether you need 2 mil for simple protection or 4 mil mylar comic bags for archival stability, we’ll match you with the right thickness.
If you don’t know your best fit, we can check your measurements and recommend the most suitable option.
Collectors and retailers use sleeves differently. So, our bags come with multiple closing styles and film types:
Ideal for sellers and collectors who frequently open and re-store books.
Best for high-volume back-issue storage or comic shop display boxes.
Used by collectors archiving valuable issues or sellers shipping signed/graded books.
We can add branding, numbering, or event-exclusive artwork without affecting archival quality.
We manufacture everything in-house, so your order runs through one workflow:
Our team works with publishers, independent artists, and long-term collectors across the UK, and we follow the same consistency standards used in high-end archival packaging.
Are mylar comic bags better than poly bags?
Yes — they hold shape longer, stay clear, and protect pages from moisture and acids better than basic plastics.
Do you offer sizes for different comic eras?
We can make bags for modern, Silver Age, Golden Age, prestige formats, and oversized issues.
Can I get backing boards with the bags?
Yes, we supply matched boards cut for each bag size.
Can these bags be heat-sealed?
If you choose heat-seal compatible bags, they can be sealed for long-term preservation.
Do you print on mylar comic bags?
We can add branding, numbering, or artwork for shops, publishers, or events.
