Are mylar bags smell proof?

Yes, when properly sealed. The aluminum-laminated layers block odor molecules from escaping the bag. Seal quality matters most — a properly heat-sealed or vacuum-sealed mylar bag is fully smell-proof, while an improperly sealed or punctured bag will leak. Child-resistant zipper bags retain most odor but aren't quite as airtight as heat-sealed pouches.

What size mylar bag do I need?

Match the bag size to your contents. 1-gram bags are for single-dose packaging. 1/8 ounce (3.5g) is the most common retail size. 1/4 ounce (7g) and 1/2 ounce (14g) are common for personal storage. 1 ounce (28g) is the largest standard size. For wholesale or dispensary use, choose 100-count or 1,000-count bulk boxes in the size you sell most.

Are mylar bags child resistant?

Some are. Standard heat-seal mylar bags aren't child resistant by default — they require heat sealing equipment to close. Grip-N-Pull style bags from Loud Lock and similar brands have child-resistant zippers that meet CPSC compliance standards required for legal cannabis sales in most US markets. Look for Grip-N-Pull or child resistant in the product name to confirm.

Can mylar bags be reused?

Heat-sealed mylar bags are typically single-use — once cut open, they can't be resealed without specialized equipment. Grip-N-Pull and zipper-style mylar bags are designed to be reused multiple times. For long-term storage, single-use heat-sealed bags preserve freshness longer; for daily personal use, reusable zipper bags are more practical.

What's the difference between mylar bags and glass jars for cannabis storage?

Both work well for different use cases. Mylar bags are smell-proof when sealed, light-proof, lighter, more compact, and disposable — ideal for retail packaging or travel. Glass jars are reusable, transparent (you can see contents), and offer the best long-term storage when paired with a humidity pack. For dispensary-style retail packaging, mylar bags are standard; for personal long-term storage, many users prefer glass jars with humidity control.

Exit bags are child-resistant mylar bags that licensed dispensaries use to package cannabis products when customers leave the store. They're required by state regulations in most US markets where adult-use cannabis is legal. The grip-n-pull design satisfies CPSC child resistance standards. Most exit bags are opaque mylar with simple printing — the same bags carried in this collection.

What Are Mylar Bags?

Mylar bags are heat-sealed, multi-layer plastic pouches made from polyester film (BoPET) laminated with aluminum and other barrier materials. The layered construction creates an air-tight, light-tight, moisture-proof, and smell-proof environment that preserves freshness and potency far better than zip-top baggies. Mylar bags are the industry standard for cannabis storage and dispensary packaging because they combine compliance (child-resistant designs), discretion (no smell escape), and shelf-life preservation in one product.

Types of Mylar Bags

The collection covers every major mylar bag format used in cannabis storage and packaging:

Smell-Proof Vacuum Seal Bags

The standard for everyday storage — heat-sealed pouches that vacuum-seal closed to lock in odor and preserve freshness. The Loud Lock smell-proof vacuum seal line is the most widely used in the industry, available in 1 gram, 1/8 oz, 1/4 oz, 1/2 oz, and 1 oz sizes in black, white, and clear options.

Child-Resistant Grip-N-Pull Bags

Compliance-grade mylar bags with child-resistant zippers that require a specific pinch-and-pull motion to open. Required for legal cannabis packaging in most US markets. The Loud Lock Grip-N-Pull line covers every standard size with both 100-count retail and 1,000-count wholesale boxes.

Printed Mylar Bags

Pre-printed mylar bags with custom designs for branded retail packaging. The Primate Glass Printed Mylar 3.5g line offers themed designs (Sugary Treats, Sweet Goodies, Money Moves, Astronaut) in 50-packs. Best for small-batch sellers, branded gifting, or anyone who wants the bag itself to be part of the product presentation.

Designer Mylar Bags

Premium printed mylar bags from brands like Ooze featuring distinctive design work in their Designer Series Octo line. Available in 1 oz capacity, 10-packs.

Sizes & Capacities

Mylar bags are sized to match common cannabis quantities:

1 gram — single-dose or small sample packaging
1/8 ounce (3.5 g) — the most common retail size, matches the standard 1/8 oz package
1/4 ounce (7 g) — quarter ounce retail and personal storage
1/2 ounce (14 g) — half-ounce retail and bulk personal storage
1 ounce (28 g) — full-ounce retail and bulk personal storage

For commercial use, pack sizes scale from 100-count retail boxes to 1,000-count wholesale boxes.

Why Mylar Bags for Cannabis Storage?

Mylar bags offer four advantages over glass jars and zip baggies:

Smell proof — the aluminum-laminated layers block odor escape completely when sealed
Light proof — opaque mylar prevents UV degradation that breaks down terpenes and cannabinoids over time
Moisture-proof — preserves the ideal humidity level for longer shelf life
Compact — flat heat-sealed bags take up far less space than glass jars

For dispensaries, the child-resistant grip-n-pull designs also satisfy state compliance requirements for adult-use cannabis sales.
