What Is Mylar bag
A Mylar bag is a type of packaging made from a strong and flexible film called BoPET (Biaxially-oriented polyethylene terephthalate), which is a polyester film made from stretched polyethylene terephthalate (PET). Mylar bags are known for their excellent barrier properties against moisture, oxygen, and light, making them ideal for long-term storage of perishable items such as food, pharmaceuticals, and cosmetics.
Key Features Of Mylar bag
- Chemical and Dimensional Stability:
Mylar maintains its shape and integrity under varying environmental conditions, resisting shrinkage or deformation. It is also chemically stable, meaning it doesn’t react with most stored contents, making it safe for food and other sensitive materials. - Flexibility and Lightweight Design:
Despite their strength, Mylar bags are thin, flexible, and lightweight, making them easy to store, transport, and handle. This is a significant advantage over rigid packaging options like cans or jars. - Gas and Aroma Barrier:
Mylar bags effectively block gases and odors, preserving the flavor and aroma of items like spices, coffee, or herbs while preventing external smells from contaminating the contents.
