5 Gallon Mylar Foil Bag 18" X 28" Sealable End (10 Pack)

The M1828HS Mylar Foil Bag is a premium high-barrier packaging solution designed for superior protection against oxygen, moisture, and contamination. With a total thickness of 5.0 mil, this heavy-duty bag offers exceptional puncture resistance, ensuring product integrity during storage and transport. It is ideal for packaging a wide variety of food products, powders, and oily or greasy substances that require an airtight seal. Engineered with a dual-layer construction, the bag features an oxygen barrier outer layer and an FDA-approved metallocene poly inner layer, which provides enhanced puncture resistance compared to standard Mylar bags. The bag’s high hot tack strength allows for a wide sealing range, making it effective at sealing through contaminants such as fine powders (e.g., protein powders, vitamin powders). The M1828HS foil bag is heat-seal only, meaning it must be sealed using a heat sealer at 400°F with 40 PSI for 1 second to ensure an airtight closure. The bag is also compatible with de-gassing valves, making it perfect for storing organically active products such as fresh roasted coffee. With an Oxygen Transmission Rate (OTR) of 0.0006 cc/100 sq. in./24 hrs and a Water Vapor Transmission Rate (WVTR) of 0.0006 g/100 sq. in./24 hrs, the bag ensures long-term freshness for sensitive products. Additionally, its Mullen Bursting Strength of 69 PSI and Puncture Strength of >25 PSI make it a cost-effective and highly durable packaging choice for industrial, commercial, and food storage applications.
