What Are Mylar Bags?

Mylar bags are made from a type of polyester film known as BoPET (Biaxially-oriented polyethylene terephthalate). This material is renowned for its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation. Mylar bags are commonly used in the food, electronics, and pharmaceutical industries due to their excellent barrier properties.

Advantages of Using Custom Mylar Bags

The multi-layer construction of these bags provides an exceptional barrier against oxygen, moisture, light, and pests, ensuring that the contents remain fresh and uncontaminated.

Versatility and Customization

Custom Mylar bags can be tailored to meet the specific needs of any product. They are available in various sizes, shapes, and colors, allowing businesses to design packaging that reflects their brand identity. The ability to print high-quality graphics and information directly on the bags further enhances their appeal.
