What Is Mylar Printing?

Mylar printing is the process of printing on Mylar, a type of durable, polyester film that's commonly used for packaging due to its strong, moisture-resistant properties.

Mylar bag printing is popular for food, cannabis, and other perishable goods because they create a barrier that helps protect contents from light, air, and moisture.

When it comes to Mylar printing, here’s what you need to know:

Materials: Mylar is made from polyethylene terephthalate (PET), which gives it its strength and flexibility. It's lightweight but also robust enough to keep its form.
Printing Techniques: Printing on Mylar often uses processes like digital printing, flexography, and rotogravure. Each technique depends on the complexity, quantity, and quality needed for the design.
Customization: Mylar is an excellent surface for customization because it holds ink well and allows for high-quality, vibrant graphics. That’s why it's commonly used for custom bags, packaging for cannabis products, coffee, chips, and more.
Heat Sealing: Most printed Mylar bags are heat-sealable, meaning you can lock the contents safely inside once the design is printed. The printing is resistant to cracking, and Mylar can withstand temperature fluctuations, so the print remains intact.
Applications: You'll find custom printed Mylar in various industries—especially food & cannabis packaging. It’s preferred for its barrier properties that keep contents fresh while showcasing a brand’s logo, design, and essential product info.
Eco-Friendliness: While traditional Mylar isn’t biodegradable, there are now more eco-friendly variations on the market, making it a growing choice for businesses looking to go green.

Why is Mylar Printing Popular?

Mylar printing is a go-to because it offers:

High clarity: Great for showing off vibrant designs.
Durability: Resistant to tears and punctures.
Barrier protection: Keeps contents safe from moisture, oxygen, and light.

If you’re creating custom bags or packaging, printed Mylar is a prime choice because it gives you eye-catching design flexibility while ensuring the integrity of whatever’s inside.

What’s the Deal with Mylar Printing?

You ever wonder what makes that shiny, tough-as-nails packaging? Yeah, that’s Mylar. Printing on this stuff? Well, it ain’t no walk in the park, but man, the results speak for themselves. Mylar, for those unfamiliar, is a polyester film—resilient, glossy, and frankly, one heck of a game-changer when it comes to keeping your products fresh and looking snazzy. But let’s break it down.

Mylar Printing Basics:

Materials: At its core, Mylar is a souped-up version of polyester film. Not the type you wear, though (unless you’ve got a funky sense of fashion). This one’s more industrial—designed to fend off everything from air to light.
Methods: You’ve got a few ways to slap a design on Mylar. Ever heard of digital printing? Flexography? Maybe rotogravure? Fancy words, but they’re just methods of getting your logo or design onto this shiny canvas. It’s a bit like painting on glass—takes some finesse, but the end result? Absolute chef's kiss.
Customization Galore: Mylar loves ink. Seriously, it clings to those colors like its life depends on it. This means your design, be it bold, pastel, or somewhere in between, pops. It’s why you see those vibrant, loud snack bags and cannabis pouches shining from shelves. And, don’t even get me started on how flexible it is for branding. The sky’s the limit.
Heat Sealing? Heck Yeah: Oh, you thought once you printed on it, you’re done? Nope. Mylar bags are heat-sealable, which is just a fancy way of saying, “seal it up, lock in the freshness, move on.” Your contents, whether it's cannabis, chips, or dried mangoes, stay as fresh as the day they were packed. Ain’t that magic?

Mylar Bags: What’s Up With Those?

Now, if you’re sitting there like, “Cool, but what exactly are Mylar bags?” Let me hit you with some knowledge.

Oxygen’s Worst Enemy: Mylar bags don’t play. They block out air and moisture like nobody’s business. This is why people love them for food storage (think grains, pasta, or, if you're a prepper, apocalypse snacks).
Light Blocker: Some Mylar bags are completely opaque, meaning no sunlight’s getting through. It’s perfect for cannabis, where you want your product fresh and untainted by UV rays.
Tougher Than You’d Think: Mylar’s not just for show. It’s seriously hard to tear or puncture. So whether it’s tumbling around in a backpack or sitting in the back of a cupboard, it’ll hold up. I once left a bag of coffee beans sealed in a Mylar bag for a month—it tasted like I’d just roasted it that morning. No joke.
Heat-Sealable Power: You ever finish packing something up and wish you could seal it with the power of a volcano? Mylar lets you do just that. Get it under a heat-sealer, and boom—it’s locked tight, fresher than ever, like a vault for your goods.
Totally Customizable: Want to print your face on a bag? Go for it. Mylar is perfect for personalized packaging—whether you’re selling gourmet popcorn or cannabis. Designs stick like glue, and the results are eye-popping. It's no wonder brands flock to Mylar bags for that extra pop on the shelves.

Mylar Balloons: Those shiny, colorful helium balloons you see at birthday parties or celebrations? Yep, those are Mylar. Printed with fun graphics, phrases, or characters, Mylar balloons are a favorite because they’re both lightweight and airtight, allowing them to float longer than regular latex balloons.
Emergency Blankets: Sometimes called space blankets, these reflective, heat-retaining blankets are made from Mylar film. Printed with safety information or branding, they’re often included in first-aid kits or used by runners after a marathon to keep warm.
Safety Labels & Industrial Tags: Mylar is often used for printing durable safety labels, warning signs, and industrial tags that need to withstand harsh conditions. Since Mylar is resistant to chemicals, oils, and abrasions, it’s a top choice for labeling machinery or equipment in industrial environments.
X-ray Film: Mylar is also used in the medical field, particularly for X-ray film. Its transparency and durability allow it to handle repeated handling while still maintaining clear, readable images. Hospitals and clinics rely on Mylar for long-term archival storage of medical imaging.
Printed Overlays for Electronics: Mylar finds its way into electronics, too. Think of printed control panels, keypad overlays, and display screens where Mylar’s flexibility and clarity are essential. It’s also resistant to scratches, making it a reliable material for heavy use products like ATMs or industrial control panels.
Custom Decals & Stickers: Because Mylar can handle wear and tear, many companies use it for custom decals or stickers that need to last outdoors. Whether it’s for cars, windows, or equipment, Mylar printing allows for vibrant, durable designs that hold up in rough conditions.
Photographic Film: In the world of photography, Mylar serves as the backing for certain types of film. It provides excellent flatness, which is key for ensuring sharp images without distortion.
