Premium Materials for Uncompromising Protection

Constructed with a multi-layer composite structure, our 3.5 Mylar bags combine the strengths of aluminum foil and food-grade polyethylene (PE):

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

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.
