5 Top Printing Techniques for Mylar Bags

Printing on black Mylar bags can result in eye-catching designs only if done using the right techniques. Some popular printing techniques include:

  • Digital Printing on Mylar Bags

One of the most popular types of printing methods used to print excellent designs on Mylar bags is digital printing. It can be done on Mylar bags directly or indirectly using heat transfer. Direct printing involves using specialized inkjet or laser printers to apply ink to the kraft Mylar bag. 

On the other hand, the indirect digital printing method uses a heat press to transfer a printed design from a specialized paper onto the Mylar bag. The best method depends on the desired quality, quantity, and available equipment

  • Offset Printing on Mylar Bags

Want to produce Mylar bag printing for bulk orders? Offset printing is one of the reliable options because it produces sharp, vibrant, and consistent graphics. Plates are used to transfer ink to the Mylar bags. Offset printing is proven to be cost-effective for high-volume jobs. 

You can rely on this process for printing logos, intricate designs, and information on Mylar bags. Food, pharmaceutical, and retail industries often choose offset printing for Mylar bags.

  • Flexographic Printing on Mylar Bags

Flexographic printing uses flexible, photopolymer plates to transfer ink for high-speed, high-volume production of custom mylar bags. It resembles offset printing and is an economical method for large orders of Mylar bags. 

The best thing about flexo printing on Mylar bags is that it produces durable and vibrant results suitable for products across various industries. The process of flexographic printing involves creating a raised image on the plate, applying ink to it, and then pressing the plate against the Mylar bags. 

  • RotoGravure Printing

Rotogravure printing exclusively uses cylindrical plates that are engraved and rotate at high speed on Mylar bags to produce high-quality prints. It is suitable for large runs to transfer ink, resulting in durable, photo-quality prints with excellent color accuracy. 

The per-unit printing cost is low when applying rotogravure printing on custom-shaped Mylar bags. However, the initial setup cost for the cylinders is high.

  • Silkscreen Printing on Mylar Bags

Silkscreen printing is all you need to consider for effective results. It uses a stencil to apply thick, vibrant, and high-grade ink layers to the Mylar bag's surface. This process involves preparing a design, creating a screen, and transferring the ink through the screen onto the Mylar bag. 

It is done before heat-curing to ensure it sticks properly and prevents smudging. Silkscreen printing requires a significant initial investment in screen and setup for long-lasting results, making it less cost-effective for small print runs.

Discovering Packaging Finishes and Special Effects

Explore a variety of custom finishing options, especially designed to boost your brand awareness, enhance your product packaging protection, and justify your premium and high pricing for your luxury products. Continue to explore the following finishing options and specialty effects for your brand benefits:

  • Matte: Matte finish is a flat, non-reflective option that absorbs light and provides a smooth, elegant appearance, and creates a lasting impression on prospects, customers, and users.
  • Gloss: In contrast to the matte, gloss finishing is a highly reflective, shiny coating used to pop colors and stand out. This is one of the best choices used for vibrant, high-energy products that need to grab attention on crowded retail shelves.
  • Soft-touch Matte: A premium finish that creates a velvet-like texture and a soft, tactile feel. Choose this finishing technique for your custom mylar bags for high-end cosmetics, luxury electronics, and premium unboxing experiences.
  • Spot UV: Like gloss, it produces a shiny, clear coat on specific areas of a matte surface to create a contrast look. This technique is one of the best options to highlight logos, brand names, or specific design patterns.
  • Holographic Film: Holographic film is a multi-colored, light-refracting film that changes color depending on the viewing angle. Give this technique priority for eye-catching, futuristic, or youthful products.
  • Clear Window: A die-cut cutout patched with transparent film to reveal the physical product inside. Use this technique for food, toys, or items where visual confirmation builds buyer trust (Window Packaging Page).

Custom Mylar Bag Artwork & Dieline Requirements

For excellent packaging for your branded custom mylar bags printed with your brand logo, custom text, and personalized theme, consider the following dieline and layout requirements:

Die Line and Layout Requirements

  • Dieline Source: Must use the template supplied by TCB.
  • Bleed Area: Leave 3 mm outside the cut line to prevent unprinted edges.
  • Safe Zone: Secure your design print by leaving a 3 mm margin inside the cut line and keeping all critical text and graphics within this boundary.
  • Non-Printable Zones: The zipper and seal areas are completely non-printable, so leave them unprinted and blank.

Color and Resolution Specs

Choose the color and resolution specs to effectively use the printing technique for your vector elements and other allied requirements.

  • Color Mode: For printing, CMYK color mode is the perfect choice; choose it only and do not use RGB.
  • Image Resolution: Keep a minimum of 300 dpi for all raster graphics and images to create vibrant, clear, and high-quality printing output.
  • Vector Elements: Logos and brand graphics must be in vector format to ensure sharpness.

Typography and Text

  • Font Treatment: Convert all text to outlines/paths to avoid font substitution errors.
  • Minimum Size: Avoid fine text under 6 pt to prevent ink bleeding or unreadable copy.

Special Material Requirements

  • White Underprint: A dedicated white underprint layer is required if you are printing on metallized or kraft film to ensure color opacity and vibrancy.

5 Considerations to Make When Printing on Mylar Bags

The following are some important considerations you must make when printing on Mylar bags. 

  • Budget
  • Turnaround time
  • Design complexity
  • Volume of production
  • Environmental impact

When choosing the right printing methods, one of the most important factors to consider is your brand’s budget. Know whether investing in a particular printing method offers value for money or not. 

For example, digital printing could be more cost-effective if you want to get bags printed in small quantities, and it is also ideal for brands that change designs frequently due to no setup costs. And when digital printing is done using water-based or low-VOC inks, it becomes environmentally friendly.
