GardaPack 15” x 20” Heavy-Duty 5 Mil  Vacuum Seal Bags 400 Pack (Clear & Black)

Optimize the quality, flavor, texture, and aroma of your products with our Heavy-Duty line of vacuum sealer bags. These bags provide excellent barrier protection against oxidation and moisture imbalance. Suitable for a wide range of applications including farming, hunting, sous vide cooking, and food processing. Also ideal for protecting non-perishable items such as electronics, collectibles, parts, tools, and other product categories.

Our Heavy-Duty proprietary material features a co-extruded, multi-layer construction that offers exceptional resistance to oxygen transmission (OTR) and moisture/water vapor transmission (MVTR), while maintaining a high level of puncture resistance. Say goodbye to concerns about leaks, odors, or environmental damage.

The clear side allows for easy viewing and identification of contents. The black side offers complete privacy and protects contents from light exposure. For full opacity, a double-bag technique can be used to create black on both sides.

Key Benefits:

• Prevents oxygen transmission for excellent oxidation control
• Retains original moisture levels and product weight
• Humidity control prevents mold, dryness, and staleness
• Slows the growth of bacteria and other contaminants
• Preserves aroma while containing odors
• Puncture-resistant to avoid tears and leaks
• Maintains texture, color, nutritional value, and potency
• Keeps products fresh 5x–10x longer than conventional storage
• Ideal for infusing flavor and advanced culinary techniques
• BPA-free, food-grade, FDA- and LFGB-compliant
• Versatile for storing perishables, non-food items, organizing, and travel

This line of GardaPack Heavy-Duty vacuum seal bags extends shelf life, preserves quality, and ensures optimal performance—keeping your products fresh and protected until you’re ready to use them.

MATERIAL

GardaPack Heavy-Duty bags are high-performance vacuum seal bags produced using a co-extrusion manufacturing process, similar to leading brands—but with a superior material composition and enhanced performance.

While our Super Heavy-Duty line uses a solvent-free composite lamination process, the Heavy-Duty line is our co-extruded option, engineered for affordability without compromising quality.

Key Features of the Heavy-Duty Line:

• Made from GardaPack’s proprietary co-extruded film, GP51HD, which combines multiple layers of polymers—primarily nylon (PA) and polyethylene (PE)—into a single, flexible, high-strength structure with excellent barrier properties.
• Contains more nylon than competing 5 Mil co-extruded brands, resulting in superior puncture resistance and a lower oxygen transmission rate (OTR).
• Includes advanced polyethylene that delivers a lower water vapor transmission rate (WVTR/MVTR) than comparable 5 Mil co-extruded brands.

Ideal for demanding applications, GardaPack Heavy-Duty bags offer a reliable, flexible, and durable solution for industries that require strong barrier protection and high performance from co-extruded materials.
