What Are Mylar Bags?
Mylar bags are flexible packaging pouches primarily made from biaxially-oriented polyethylene terephthalate (BoPET). They are often combined with layers of aluminum or polyethylene, creating a strong barrier against light, air, and moisture.
Unlike regular plastic bags, Mylar bags help preserve freshness, extend shelf life, and protect sensitive products. At Packaging Ship, we offer custom Mylar bags designed to meet your unique product and branding requirements.
