What Exactly Are Mylar Bags?

Mylar, a trademarked name for BoPET (biaxially-oriented polyethylene terephthalate), is a type of polyester film created by DuPont in the 1950s. It’s a superhero material—strong, clear, and capable of shielding its contents from moisture, light, and gases. When this film is crafted into bags, it transforms into an incredibly versatile packaging solution.

Why Print on Custom Mylar Bags?

Printing on Mylar bags isn’t just about looks. Here’s why it’s a game-changer:

1. Brand Power: Custom mylar bag printing turns your bags into mini billboards, showcasing your brand’s logo, colors, and message.
2. Regulatory Compliance: Industries like pharmaceuticals require clear labeling. Printing directly on the bag ensures you meet these strict standards.
3. Shelf Appeal: Eye-catching designs make your product stand out, attracting more customers.
4. Information Hub: Custom printing provides essential details about the product, usage instructions, and any other relevant info.

Printing Methods: The How-To of Custom Mylar Bags

There are several methods to print on Mylar bags, each with its own perks. Your choice depends on your budget, design complexity, and the quantity of bags you need.

1. Flexographic Printing

The Lowdown: Also known as flexo printing, this method uses a flexible relief plate to transfer ink onto the bags.

Pros:

• Economical for large runs.
• High-speed production.
• Works on various substrates.

Cons:

• High initial setup costs.
• Not ideal for highly detailed designs.

2. Gravure Printing

The Basics: This technique involves engraving the image onto a cylinder, which then transfers ink to the Mylar bags.

Pros:

• Produces high-quality, detailed images.
• Best for long runs.

Cons:

• Expensive setup. Not cost-effective for small batches

3. Digital Printing

The Scoop: Digital printing uses digital files to print directly onto the bags without needing plates.

Pros:

• Great for short runs and quick turnarounds.
• Easy customization and variable data printing.

Cons:

• Higher cost per unit for large runs.
• Limited substrate options.

4. Screen Printing

The Gist: This method uses a stencil (or screen) to apply layers of ink on the bags.

Pros:

• Excellent for bold, vibrant colors.
• Cost-effective for small to medium runs.

Cons:

• Not suitable for intricate designs.
• Slower than other methods.

The Printing Process for Custom Mylar Bags

1. Designing Your Bag
   Begin with a killer design. Collaborate with a graphic designer to create something that reflects your brand’s identity—think logos, colors, and any other elements that scream “you.” Make sure to include all necessary regulatory info.
2. Choosing Your Printing Method
   Decide on the best printing method based on your needs. Discuss your options with your printing service provider to find the perfect fit.
3. Prepress Preparation
   Before printing, you’ll need to prepare:

• Proofing: Review a proof of your design for errors or tweaks.
• Color Matching: Ensure the colors in your design match your brand standards.
• Plate Making: If using flexo or gravure printing, create the necessary printing plates.

4. Printing
   The actual printing process varies:

• Flexographic and Gravure Printing: Set up the press, load the Mylar film, and run the print job.
• Digital Printing: Load your design into the digital printer, and print directly onto the Mylar bags.
• Screen Printing: Prepare screens for each color and manually or automatically feed the bags through the screens for ink application.

5. Post-Printing Processes
   After printing, several post-printing steps may be necessary:

• Lamination: Add a protective layer for extra durability.
• Cutting and Sealing: Cut the printed film into individual bags and seal them as needed.
• Quality Control: Inspect the bags to ensure they meet quality standards.
