In an era where food waste and environmental sustainability are critical concerns, preserving freshness while minimizing ecological impact has never been more important. Enter 3.5 Mylar bags—a revolutionary packaging solution designed to safeguard your products from external threats like moisture, oxygen, and light, ensuring extended shelf life without compromising quality.

The Science Behind 3.5 Mylar Bags

Constructed with a multi-layer composite design, these bags combine cutting-edge materials to create an impenetrable barrier:

Aluminum Foil Layer: Blocks UV rays and oxygen, preventing oxidation and nutrient degradation.

Food-Grade Polyethylene (PE) Lining: Provides a safe, flexible inner layer for direct food contact.

Reinforced Polypropylene (PP) Zipper: Ensures an airtight, resealable closure for repeated use.

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

Certified FDA-approved and available in biodegradable PLA/PBAT blends, these bags balance safety and sustainability, making them ideal for organic or human-grade products.

How 3.5 Mylar Bags Maintain Freshness

Airtight Seal Technology

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

Moisture & Odor Resistance

The aluminum and PE layers repel moisture, preventing mold growth and preserving texture. 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 99% of UV radiation, preserving vitamins and preventing color fading in products like dehydrated fruits or herbs.

Versatile Applications for Every Need

3.5 Mylar bags are engineered to meet diverse storage requirements:

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

Herbal Products: Cannabis, teas, and supplements.

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

Household Essentials: Bath salts, candles, or small electronics.

Available in sizes from 3.6” x 5” for individual servings to 4” x 7” for bulk storage, they offer flexibility for both personal and commercial use.

Expert Tips for Optimal Use

Sealing Techniques: Use a heat sealer or flat iron for airtight closure. Double-sealing adds extra security.

Oxygen Absorbers: Pair with these packets to eliminate residual oxygen, especially for long-term storage.

Storage Conditions: Keep bags in cool, dark environments (e.g., pantries or freezers) to maximize efficacy.

Reusability: Hand-wash and air-dry for repeated use, reducing plastic waste.
