When choosing custom mylar bags for cannabis products, design and size get most of the attention—but thickness is just as important. The wrong thickness can lead to odor leaks, damaged products, or unnecessary cost. The right thickness protects your product, improves shelf life, and enhances customer perception.
In this guide, we’ll break down mylar bag thickness options, how they affect performance, and how cannabis brands can choose the best option for flower, pre-rolls, edibles, and concentrates.
What Is Mylar Bag Thickness?
Mylar bag thickness is usually measured in microns (µm) or mil (1 mil ≈ 25.4 microns). Thickness determines:
- Odor protection
- Moisture resistance
- Tear resistance
- Overall durability
- Premium feel in hand
Most cannabis mylar bags range from 80–150 microns, depending on use.
Common Mylar Bag Thickness Options
1. 80–90 Microns (Lightweight Option)
Best for:
- Promotional giveaways
- Single-use samples
- Budget-focused brands
Pros:
- Lowest cost
- Lightweight for shipping
Cons:
- Less durable
- Easier to crease or puncture
- Reduced odor barrier
This thickness is best when cost matters more than longevity.
2. 100–110 Microns (Most Popular Choice)
Best for:
- 3.5g flower mylar bags
- Pre-roll bags
- Edibles
Pros:
- Strong odor protection
- Good balance of cost and durability
- Professional retail feel
This is the industry standard thickness and the safest choice for most cannabis brands.
3. 120–130 Microns (Premium Protection)
Best for:
- High-end flower
- Shaped mylar bags
- Multi-pack pre-rolls
Pros:
- Excellent smell-proof performance
- Strong tear resistance
- Premium hand feel
Brands using thicker bags often see higher perceived value, especially for top-shelf products.
4. 140–150 Microns (Heavy-Duty Packaging)
Best for:
- Concentrates
- Bulk flower packaging
- Long-distance shipping
Pros:
- Maximum protection
- Best moisture and oxygen barrier
Cons:
- Higher cost
- Slightly heavier
This thickness is ideal for products that require extended storage or shipping durability.
How Thickness Affects Odor Control
Odor leakage is one of the biggest complaints from consumers. Thicker mylar bags:
- Reduce air permeability
- Improve heat sealing strength
- Maintain terpene freshness
For cannabis flower and pre-rolls, 100 microns or thicker is strongly recommended.
Thickness vs Cost: Finding the Balance
While thicker bags cost more per unit, they can:
- Reduce product returns
- Improve customer satisfaction
- Support premium pricing
Smart brands evaluate cost per protected gram, not just cost per bag.
Custom Printing and Thickness Compatibility
Thicker mylar bags:
- Hold ink better
- Reduce color distortion
- Improve matte and soft-touch finishes
If branding matters, avoid ultra-thin materials.
Final Thoughts
Choosing the right mylar bag thickness is about protecting your product, your brand, and your margins. For most cannabis businesses, 100–120 microns delivers the best balance of performance and cost.
If you’re offering premium products or shipping long distances, thicker is worth the investment.
