Mylar Bag Sizes Explained: How to Choose the Right Size for Your Cannabis Brand

Choosing the right mylar bag size is one of the most important packaging decisions a cannabis brand can make. The wrong size can hurt product presentation, cause excess air in the pouch, or fail to meet compliance requirements. This guide breaks down the most common cannabis mylar bag sizes — from single-gram pouches to full-pound bags — so you can confidently stock the right packaging for your product line.

Why Mylar Bags Are the Industry Standard

Mylar bags dominate cannabis packaging for good reason. Their multi-layer barrier technology blocks moisture, UV light, and oxygen — keeping flower, edibles, and extracts fresh far longer than standard plastic bags or paper. For wholesale buyers, mylar bags also offer superior print quality for branding, making them the go-to choice for dispensaries, brands, and cultivators looking to stand out on the shelf.

1g Mylar Bags — Single-Serve Samples and Pre-Packs

Typical dimensions: approximately 3" × 4" (varies by supplier).

One-gram bags are ideal for single-dose pre-packs, sample programs, and budget-friendly grab-and-go retail formats. They're popular with dispensaries running loyalty or intro programs. Because they hold just one gram, headspace is minimal — important for freshness. If you're offering trial sizes or premium single-strain SKUs, 1g bags are your go-to.

3.5g Mylar Bags — The Eighth Ounce Standard

Typical dimensions: approximately 4" × 5" to 4" × 6".

The 3.5g (one-eighth ounce) is the most popular cannabis retail weight in the U.S. These bags strike the balance between affordability and premium presentation. Most dispensary shelf SKUs ship in 3.5g mylar bags, and they're the workhorse of branded cannabis packaging. If you're launching a line, this is likely your highest-volume bag size.

7g Mylar Bags — Quarter-Ounce for Value Buyers

Typical dimensions: approximately 5" × 7" to 5" × 8".

Seven-gram bags serve the quarter-ounce segment — popular with value-focused buyers who want more product per purchase. These bags offer a noticeably larger canvas for branding while keeping unit economics favorable. Brands running multi-tier product lines (budget, mid, premium) often stock 7g as their mid-tier format.

14g Mylar Bags — Half-Ounce for Regular Consumers

Typical dimensions: approximately 6" × 9".

Half-ounce bags appeal to repeat customers who know what they like. At 14g, bags need to be sturdy enough to hold meaningful weight without stressing seams. Look for reinforced bottom gussets and resealable zippers. Child-resistant press-and-pull closures are increasingly common at this size for compliance.

28g Mylar Bags — Full Ounce, Maximum Brand Impact

Typical dimensions: approximately 7" × 10" to 8" × 10".

One-ounce mylar bags are a premium retail format — often used by top-shelf brands that want to command attention. The larger surface area gives your designer room to tell your brand story. For cultivators selling direct, 28g bags reduce packaging SKU complexity while appealing to connoisseur buyers.

Pound Bags — Bulk Wholesale and Commercial Transfers

Typical dimensions: 12" × 16" and larger; often available in heat-seal-only format.

Pound-sized mylar bags are typically used for commercial cannabis transfers, long-term storage, or bulk wholesale. These are not retail-facing — they prioritize barrier performance over aesthetics. If you're a cultivator moving product between facilities or storing harvests, pound bags offer the best cost-per-gram protection.

MOQ and Ordering Considerations

• Match your volume: Higher-volume sizes (3.5g, 7g) typically have the best wholesale pricing tiers at low MOQ.
• Custom printing: Custom-printed mylar bags usually require higher MOQs — plan SKUs before committing to print runs.
• Child-resistant closures: Many states require CR packaging — confirm compliance requirements in your market before ordering.
• Stock vs. custom: Stock mylar bags with your own labels are fastest to market; custom-printed bags offer the best shelf presence.
