These bags offer useful barrier properties and can help protect products from moisture, oxygen, light, and odors. Custom Mylar bags can also be tailored by thickness, size, closure, printing, finish, and overall structure to meet specific product and branding requirements. To know more about how Mylar bags can be customized, keep reading till the end.
Understanding the Mylar Material
Mylar bags are made of mylar sheets that are essentially polyester films. These films are produced from PET, polyethylene terephthalate. PET sheets are very stretchable and have high tensile strength. Which is (largely) stretched to form a long and thin chain of small blocks of the same size.
PET is a fully transparent polyester sheet, but can be modified into different colors by blending it with aluminium foil, which ultimately forms the Mylar sheets.
Mylar strictly prohibits light and gases from entering the bag, giving food-safe and food-preserving properties to the Mylar bags.
Commercial Mylar bags typically use multiple laminated layers rather than PET alone. This construction combines strength, barrier protection, printability, and heat-sealing performance.
Mylar Bag Layer Structure
- Outer PET: Print surface, strength, and abrasion resistance
- Barrier layer: Aluminum foil or metallized PET protects against light, oxygen, and moisture
- Inner PE or LLDPE: Heat-sealing and suitable product-contact layer
Foil provides a higher barrier and complete opacity, while metallized PET is lighter and generally lower cost.
Benefits Not Easy to Overlook
Mylar bags offer diversified and flexible packaging because of their unavoidable benefits, the reason why these bags are used in a number of industries. These bags are mostly used to pack plenty of diverse food items. Some essential/vital properties, due to which Mylar bags are highly food-safe, are:
- Water Resistant
