Matte Black Mylar Bags

High-barrier matte black Mylar bags for packaging product that needs to stay fresh. The foil layer blocks moisture, oxygen, and UV light — the three things that degrade aroma, flavor, and potency — while the opaque matte finish keeps contents completely private.

Sizes & quantities

Larger pack sizes carry a substantially lower cost per bag — worth comparing if you're buying regularly.

Key features

• High-barrier construction — blocks moisture, oxygen, and UV light
• Matte black, fully opaque — discreet, and gives a clean surface for labels
• Puncture-resistant — won't tear or leak in transit
• Heat-sealable — seal with any impulse sealer for a genuinely airtight closure

What people package in these

• Herbs and spices — holds aroma and flavor
• Coffee and dried goods
• Edibles and consumables
• Retail products needing custom branding — the matte surface takes labels well
• Small collectibles and parts needing protection from air and light

Sealing

These need heat sealing to actually perform. Folding or taping the top leaves the barrier open and you lose the protection you paid for. An inexpensive impulse sealer handles all sizes.
