3. How To Pick The Best Mylar Bag Mil Thickness To Maximize Product Shelf Life?
Combining lab test data and decades of industrial experience, OK Packaging delivers accurate commercial-grade mylar bag thickness selection standards.
3.1 Commercial-Grade Mylar Bag Thickness Grading & Scenario Application
4–5mil standard commercial mylar bags: The most versatile option, balancing barrier performance and unit cost for coffee, nuts, supplements and medium-term preserved goods
5.7–7mil heavy-duty aluminum foil mylar bags: Ultra-high barrier blocks oxygen, UV rays and odors, supporting 25–30 years of long-term fresh-keeping storage
7.5mil ultra-thick industrial mylar bags: Superior puncture and tear resistance for industrial precision materials and ultra-long-term sealed storage
3.2 Professional Identification: AL Foil VS VMPET Metallized Mylar Bags
Many suppliers disguise low-cost VMPET metallized film as pure aluminum foil, causing barrier failure after folding and extrusion. OK Packaging strictly distinguishes the two materials to safeguard client interests:
AL-PET/AL/PE full aluminum foil mylar bags: Solid integrated aluminum layer with zero light and oxygen penetration, delivering stable barrier performance for high-value long-term packaging
VMPET metallized mylar bags: Lightweight and low-cost, only suitable for short-term display and regular packaging, not for long-term preservation or odor-proof use
