Custom Magazine Mylar Sleeves

Film Thickness, Flaps and Closures

Mylar comes in several gauges. Thinner film is lighter and cheaper to store in quantity, while thicker film feels rigid and gives the most protection for high-value issues. Many dealers use a thinner gauge for general stock and a thicker one for their showcase copies. If you only need a simple open sleeve, flat mylar bags without gussets are the plainest option.

The opening matters as much as the film.

• Open top: the magazine slides in and out freely, fine for storage in a closed box.
• Tuck flap: a fold-over flap closes the sleeve without adhesive touching the magazine.
• Resealable strip: an adhesive strip on the flap keeps the sleeve closed for posting and handling.
• Side opening: useful for wide or oversized magazines that are awkward to slide in from the top.

Backing Boards and Branded Inserts

On its own, a sleeve protects the surface but does not stop a magazine from bending. Adding a stiff backing board behind the magazine keeps it flat on a shelf, in a box or in the post. Boards are cut to sit just inside the sleeve so they do not stretch the film.

For shops and dealers, the backing board is also a branding opportunity. We can print your shop name, logo and website on the back of each board, along with a space for a price, grade or issue number. Every customer who takes a magazine home then has your details on the back, and staff can see key information without opening the sleeve.

We can also print small header cards or labels that sit inside the sleeve above the magazine, which is handy for convention stands where copies are flicked through quickly. Our guide to board and card types explains how backing board stiffness varies.

Who Orders Mylar Sleeves for Magazines

Comic and collectables shops order them for magazine-size comics, art books and annuals. Music and film memorabilia dealers use them for back issues of specialist titles. Sports collectors use them for match programmes and football magazines, often alongside programme-sized sleeves.

Independent publishers and fanzine makers use sleeves to protect limited print runs and special editions, sometimes selling them pre-sleeved with a printed backing board. Libraries, archives and private collectors also order them for long-term storage of periodicals they want to keep in good order. Sellers who want a fully closed pack for postage sometimes choose heat-seal mylar bags for postage instead.

Storing, Handling and Selling Sleeved Stock

At a collectors' fair, buyers flick through boxes fast. Sleeved magazines with a printed board behind them stand upright in the box, show their covers clearly and carry the price and grade in the same spot on every copy, so customers can browse without asking. Dealers tell us this one change speeds up a busy stand more than anything else.

Online, the sleeve gives a cleaner photo. Shoot the magazine in its sleeve under soft, angled light to avoid glare, and the cover reads clearly while buyers can see you store stock properly. That reassurance matters when someone is paying a premium for a scarce issue they cannot inspect in person.

When posting, slide the sleeved magazine and board between two pieces of stiff card or into a rigid mailer, and mark the parcel as not to be bent. A sleeve keeps moisture and dirt off the cover in transit, but it cannot stop a parcel being folded through a letterbox, so the outer packaging still has to do that job.

Sleeved magazines are best stored upright in a sturdy box, packed firmly enough that they do not slump, but not so tightly that they are hard to pull out. Keep the box away from radiators and damp walls, and out of direct sunlight, which fades covers even through clear film.

When sliding a magazine into a sleeve, hold the sleeve open with one hand and guide the magazine in with the board behind it, so the cover does not drag against the film. Never tape a sleeve shut directly over the magazine; use a flap or resealable strip so no adhesive gets near the paper. Sleeved issues file neatly upright in printed storage boxes for comics, which also take slim magazines.
