In an era where product integrity and sustainability are paramount, 3.5 Mylar bags emerge as a revolutionary packaging solution designed to lock in freshness, flavor, and quality while minimizing environmental impact. Crafted with precision-engineered materials and advanced sealing technology, these bags offer an unbeatable barrier against external threats, making them ideal for industries ranging from food and cannabis to pharmaceuticals and retail.

Premium Construction for Unmatched Protection

3.5 Mylar bags feature 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.

Core Advantages for Superior Preservation

Hermetic Seal Technology

The zip-lock closure creates a hermetic 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.

Odor & Moisture Resistance

The aluminum and PE layers repel moisture and trap odors, making them ideal for strong-smelling items like cannabis or fish-based pet food.

Puncture-Resistant Design

Tested to withstand sharp edges and rough handling, these bags feature reinforced seams for load-bearing up to 20lb, ensuring safe transportation and storage.

Child-Resistant Compliance

Many versions meet ASTM and CPSC standards, offering peace of mind for households with children or sensitive products.

Versatile Applications

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.

Available in sizes from 3.5g (3.6” x 5”) for individual servings to bulk capacities, they adapt to personal or commercial use.

Customization & Sustainability

Elevate your brand with tailored designs:

Printing Options: Full-color logos, nutritional labels, or vibrant patterns using advanced offset or digital printing.
