What Are 3.5g Mylar Bags?
3.5g Mylar bags are small, high-barrier, resealable pouches specifically designed to hold 3.5 grams (or one-eighth of an ounce) of dry goods—most notably cannabis flower. In the cannabis industry, “3.5g” is a standard unit often referred to as an “eighth,” and packaging in this size has become a staple for dispensaries, cultivators, and cannabis brands.
Made from durable, multi-layered polyester film (PET) combined with a metallic foil or clear laminate, Mylar bags offer exceptional protection against moisture, air, light, and odor—essential for maintaining product freshness, potency, and shelf life.
Why Use 3.5g Mylar Bags?
Whether you’re a startup cannabis brand, a distributor, or an established dispensary, 3.5g mylar bags offer a cost-effective, customizable, and compliant solution for product packaging. Here’s why they’re essential:
✅ Ideal for Cannabis Packaging
3.5g is the industry standard for retail cannabis flower. These bags are designed to perfectly fit an eighth ounce of product without excess air space, ensuring freshness and presentation quality.
✅ High Barrier Protection
The multi-layer film structure offers smell-proof, moisture-resistant, and UV-blocking capabilities—protecting delicate products like cannabis, herbs, tea, or even powdered supplements from degradation.
✅ Heat-Sealable + Resealable
Most 3.5g mylar bags are heat-sealable for tamper-evidence, with a zip-lock feature for customer convenience. This dual-layer sealing ensures compliance while improving consumer experience.

Lightweight, flat when empty, and easy to store or ship in bulk, these bags help reduce shipping costs and shelf footprint.
