In an era where product integrity and sustainability are paramount, 3.5 Mylar bags emerge as a game-changing packaging solution for preserving freshness, flavor, and quality. Engineered with advanced materials and precision design, these bags offer an unbeatable barrier against environmental threats, making them ideal for industries ranging from food and cannabis to pharmaceuticals and retail.

Premium Materials for Unmatched Protection

Our 3.5 Mylar bags are constructed using a multi-layer composite structure that combines durability and functionality:

Aluminum Foil Layer: Blocks 99% of UV rays, oxygen, and moisture, preventing oxidation, nutrient loss, and mold growth.

Food-Grade Polyethylene (PE) Lining: A flexible, BPA-free inner layer ensures direct contact safety for edibles, while enhancing puncture resistance.

Reinforced PP Zipper: Provides an airtight, resealable closure for repeated use, maintaining freshness and convenience.

PET Exterior: Adds structural rigidity and clarity for branding visibility.

Certified FDA-approved and available in biodegradable PLA/PBAT blends, these bags balance safety, sustainability, and performance.

How 3.5 Mylar Bags Ensure Maximum Freshness

Hermetic Seal Technology

The zip-lock closure creates an airtight seal, locking in freshness and flavor while excluding harmful microbes. Paired with oxygen absorbers, these bags extend the shelf life of dry goods like coffee, grains, and herbs for up to 25 years.

Moisture & Odor Resistance

The aluminum and PE layers repel moisture, preventing texture degradation. For sensitive items like cannabis or fish-based pet food, the odor-blocking properties ensure discreet storage.

UV Protection

The aluminized layer shields contents from UV radiation, preserving vitamins and preventing color fading in products like dehydrated fruits or supplements.

3.5 Mylar bags cater to diverse storage needs:

Food & Beverages: Coffee beans, nuts, pasta, and freeze-dried meals.

Herbal Products: Cannabis, teas, and dietary supplements.

Pet Food: Dry kibble or raw diets, protected from pests and spoilage.

Retail & Pharmaceuticals: Small electronics, cosmetics, or medications requiring moisture-resistant storage.
