What Is Mylar and Why Do You Need It?
Mylar is the thin, transparent film that transforms a printed paper design into a finished, durable button. During the pressing process, the mylar disc locks into place between the metal shell and your artwork. Creating a crystal-clear protective layer that resists scratches, moisture, fingerprints, and fading.
For the 1-1/4" size specifically, mylar is what separates a homemade-looking button from a professional one. This is the button size most buyers associate with retail pins and band merch — which means the quality of the mylar covering matters more here than at any other size. A clean, flat mylar disc gives you the glassy, professional finish customers expect from a button they'd pay for.
Who Uses 1.25" Round Mylar?
The 1-1/4" size is the most versatile and commercially popular button dimension — which makes it the workhorse of high-volume button operations:
- Campaign and political buttons — 1.25" is the classic campaign button size. Political candidates, advocacy groups, union organizers, and ballot initiatives rely on this size because it fits a slogan and graphic cleanly while staying affordable in the thousands. Stock up before election season. Campaigns burn through mylar fast.
- Craft fairs and Etsy sellers — If you sell handmade buttons, pins, or flair on Etsy, craft markets, or convention floors, 1.25" is your bread and butter. Buyers recognize this size as the standard "button" size. 1,000 mylar discs covers roughly a full season of weekend markets.
- Schools, libraries, and PTAs — Bulk 1.25" mylar is ideal for school spirit buttons, reading-program rewards, library summer challenges, homecoming merchandise, and PTA fundraisers. The larger surface gives teachers room for a logo plus student art without squeezing the design.
- Promotional and corporate swag — Marketing teams, trade show booths, event planners, and branded merch shops use 1.25" buttons as a low-cost giveaway that doesn't feel cheap. A printed logo looks sharp at this size, and a glossy mylar finish makes the button feel premium in hand.
- Replacement stock — Mylar is the part of the button-making process most prone to getting scratched, stuck together, or lost. Every serious button operation keeps a backup pack of 1,000 on the shelf.
How to Use Mylar in Your Button Maker
Mylar loads as the final layer in your button press. Here's the sequence:
- Print and cut your artwork to a 1-5/8" circle. A circle cutter or punch makes this fast and consistent.
- Load the metal shell face-down into the top die of your 1-1/4" button maker.
- Drop your artwork on top, design-side up so it faces out when finished.
- Add a single mylar disc on top of the artwork. One disc only — two mylars pressed together is the number-one cause of misfires.
- Rotate the die, insert the back piece, and pull the press handle. The mylar seals around the shell edge to lock in your design.

Pro Tips for Working with Mylar
- Watch for static cling. 1.25" mylar discs are notorious for sticking together because of static electricity. Flex the stack and fan the discs apart before loading. This single habit prevents most jams.
- Keep the dies clean between runs. Paper dust and tiny ink particles build up on the press dies during long production runs and can get trapped under the mylar, creating visible specks. A quick wipe with a dry microfiber cloth every 100 buttons keeps finishes crystal clear.
- Buy in bulk for production jobs. The 1,000-count pack is priced for serious users. If you're running campaign jobs, wholesale orders, or large craft inventory, two or three packs on hand is cheap insurance against a mid-run shortage.

Frequently Asked Questions
What is the actual size of 1.25" mylar?
The actual diameter is 1.629" (roughly 1-5/8"). This is deliberately larger than the finished 1-1/4" button so the mylar has material to wrap around and seal the edge during pressing. If the mylar were cut to exactly 1.25", it wouldn't cover the full surface of your finished button.
Why is 1.25" a popular button size?
1-1/4" hits the sweet spot between visibility and cost. Large enough to fit readable text and detailed artwork, small enough to pin comfortably to a t-shirt, backpack, or lanyard. It's the go-to size for political campaigns, band merch, craft fair sellers, and retail promotional buttons.
What's the difference between 1" and 1.25" mylar?
The two sizes are NOT interchangeable. 1" mylar measures 1.313" across and fits only 1" buttons. 1.25" mylar measures 1.629" across and fits only 1-1/4" buttons. Using the wrong size will jam your press or produce an incomplete seal. Always match mylar size to your button shell size.
Will this mylar work with Badge-A-Minit or other 1-1/4" machines?
This is industry-standard 1-1/4" mylar, compatible with most standard 1.25" button maker presses including American Button Machines, Tecre, and similar brands. Badge-A-Minit uses non-standard sizing on some of their machines, so if you own a BAM press, confirm the required mylar diameter in your machine's documentation before ordering.
How should I store mylar to keep it flat?
Keep mylar in its original packaging, laid flat, in a cool and dry spot. Heat can warp the discs, and humidity can cause them to cling together more aggressively. Avoid storing near windows or heating vents. Stored properly, mylar has essentially an unlimited shelf life. You can buy in bulk without worrying about it going bad.
