What Are 3.5 Gram Mylar Bags?

A 3.5 gram mylar bag is a packaging pouch sized specifically for the cannabis “eighth” — one-eighth of an ounce, the most widely sold flower weight in the U.S. cannabis retail market. While 1 ounce technically equals 28.3495 grams (making a true eighth 3.54g), the industry has long standardized on 28g per ounce, so an eighth is sold and packaged as 3.5 grams.

This isn’t just a smaller version of a generic mylar bag. The 3.5g format has developed its own dimensional standards because the volume of 3.5 grams of flower — depending on density — needs a bag that displays the product properly, leaves room for compliance labeling, and seals tightly without crushing the trichomes.

Engineered for the Eighth Format Sized precisely for 3.5 grams of cannabis flower — enough room for proper presentation and compliance labels, without excess space that misrepresents product volume.

Multi-Layer Barrier Protection PET/AL/PE laminate construction delivers moisture resistance, light blocking, and oxygen barrier performance, helping preserve terpene profile and flower freshness over extended shelf life.

Resealable Zipper Closure Top zipper closure allows consumers to reseal the bag after each use, maintaining a stable internal environment between sessions.

Stand-Up, Shelf-Ready Structure Bottom gusset enables the bag to stand independently on dispensary shelves, maximizing front-panel visibility for brand artwork and strain identification.

Premium Custom Printing Full-color CMYK printing combined with finishes such as soft-touch matte, gold foil, holographic effects, and spot UV — giving each strain its own distinct shelf identity within a unified brand system.

Compliance-Friendly Label Layout Designs can be structured with reserved zones for THC/CBD content, batch numbers, warning statements, and state-required symbols, ensuring regulatory information doesn’t disrupt brand visuals.

3.5g mylar bags are built for the U.S. cannabis retail supply chain, where each use case carries its own packaging demands.

Dispensary Retail Display The eighth is the highest-volume flower SKU in most U.S. dispensaries. 3.5g bags are typically shelved front-facing in display cases, where consistent dimensions and bold front-panel artwork drive purchase decisions. Brands often release multiple strains under one visual system — same size, same structure, distinct artwork per strain — creating a recognizable shelf identity.

Multi-Strain SKU Management for Cannabis Brands Cannabis brands frequently manage dozens of strain SKUs, each requiring its own packaging artwork. Because 3.5g is the most frequently restocked weight, brands need a packaging partner capable of handling small batches, fast artwork turnarounds, and frequent reprints. Digital printing options support this workflow with low setup costs and quick changeovers between SKUs.

State-Specific Compliance Labeling U.S. cannabis packaging regulations vary by state — covering THC potency disclosure, warning statements, traceability codes, and universal symbols. 3.5g bag designs are typically planned in advance to balance brand visuals with these required compliance elements, avoiding the need for sticker overlays that obscure artwork.
