Printed Mylar bags are composed of a polyester film known as Bopped (Biaxially-oriented polyethylene terephthalate), which is metallized with a thin layer of aluminum. This combination creates a robust, flexible, and lightweight material that effectively shields contents from external factors such as light, moisture, and oxygen.
Advantages
