Airtight 3.5 Gallon Mylar Bags - Ultimate Moisture & Oxygen Protection!
Safeguard bulk food, emergency supplies, or commercial goods with our Airtight 3.5 Gallon Mylar Bags - engineered for maximum moisture resistance and long-term storage. Ideal for preppers, food brands, or households, these heavy-duty bags combine military-grade barrier technology with unmatched durability to preserve freshness and protect against spoilage, pests, and environmental damage.
Why These Bags Stand Out:
3.5 Gallon Capacity: Perfect for large-quantity storage of grains, rice, beans, pet food, coffee, or emergency supplies (e.g., freeze-dried meals).
Airtight & Moisture-Proof: Multi-layer Mylar® laminate (PET/Aluminum/PE) blocks oxygen, UV light, and humidity, extending shelf life by years.
Industrial-Strength Seals: Thick, heat-sealed edges and airtight closures prevent leaks and ensure tamper-proof protection.
Reusable & Durable: Tough, puncture-resistant material withstands rough handling - reuse for storage or transport.
Customizable Branding: Add labels, logos, or instructions (optional) for commercial use or resale.
Whether stocking a pantry, prepping for emergencies, or packaging bulk goods, these bags deliver reliable, long-lasting protection while saving space and reducing waste.
