Mylar Bag Thickness Guide helps buyers understand thickness measurements and choose the right barrier for their products.
Thickness is measured in microns (μm) or mils (mil). One mil equals 25.4 microns. Higher thickness generally provides better barrier protection.
Common mylar bag thicknesses include 2.5 mil (63.5 microns), 3.5 mil (89 microns), and 5 mil (127 microns) for various barrier requirements.
The right thickness depends on product shelf life, barrier requirements, handling conditions, and cost considerations.
High-barrier materials like VMPET and aluminum foil provide excellent oxygen and moisture protection for premium products.
Artwork should be created after the pouch size and dieline are confirmed to avoid layout mistakes and production delays.

Can I mix different thicknesses?
Yes. Different pouch types can use different thicknesses. Discuss your specific needs with our team.
Next step
Confirm your packaging size, material, and dieline before creating final artwork. This helps reduce printing mistakes, wrong panel layout, poor shelf appearance, and production delays.
