Custom Mylar bags are high-barrier, flexible pouches that lock out moisture, oxygen, light, and odors — the four things that quietly destroy food, herbs, coffee, and supplements. Printed to your exact size and artwork, they keep products fresher for longer and make your brand look instantly premium on a shelf.
What Makes Mylar a True Barrier
Mylar bags aren't single sheets of plastic. They're multi-layer laminates — typically a PET outer layer for structure and print, an aluminum foil core that blocks oxygen and light, and a PE inner layer that heat-seals safely. That metal core is what makes the bag smell-proof, UV-blocking, and airtight.
Thickness matters: our standard range is 3.5 to 7.0 mil. Thinner film suits light retail items like tea and cosmetics; mid-range film handles snacks, coffee, and dried goods; heavier 6.0-7.0 mil film is for bulk, high-odor, and child-resistant packaging that has to survive handling.
Types of Mylar Bags We Make
- Flat Pouches — slim 3-side seal bags that store flat and ship cheap.
- Stand-Up Pouches — a gusseted base that sits upright on the shelf, ideal for retail.
- Side-Gusseted Bags — extra capacity for bulk snacks, pet treats, and large orders.
- Zipper / Resealable Pouches — customers tear, reseal, and use again while freshness stays locked in.
- Child-Resistant Pouches — compliant zipper closures for cannabis and CBD edibles.
Closures: Heat Seal, Zipper, Valve & More
Pick the closure that matches how your product is used:
- Heat Seal — airtight, tamper-evident, ideal for one-use packs.
- Resealable Zipper — for products consumed over multiple servings.
- Child-Resistant Zipper — for regulated markets.
- One-Way Degassing Valve — lets roasted coffee release CO₂ without letting oxygen in.
- Tear Notch & Hang Hole — easy open and peg-wall retail ready.
Printing & Finishing
High-resolution digital printing for short to medium runs, plus CMYK and Pantone matching when your brand color has to be exact. Finish with matte for a soft premium feel, glossy for vibrant pop, soft-touch, or metallic/holographic for a standout shelf presence. Add windows for product visibility or full-wrap artwork that uses every panel.
