How Does Smellproof Packaging Work?
Smellproof packaging works by creating a sealed environment that blocks terpenes and odor molecules from escaping. This involves both material composition and construction. At Black Unicorn, we develop packaging with multi-layered barriers that prevent scent leakage, no matter the product inside.
Our packaging achieves this through a combination of:
- High-density barrier films that trap odor at the molecular level
- Laminated layers that resist penetration from gases and oils
- Hermetic seals, both heat-activated and zip-style, that eliminate air exchange
- Interior linings that isolate the cannabis from exterior surfaces
- Precision seam construction to prevent gaps and air leaks
Each of those plays a role in keeping scent inside the packaging where it belongs. Whether you’re storing flower, pre-rolls, concentrates, or infused edibles, our smellproof cannabis packaging holds up in storage, transport, and retail environments.
Today’s cannabis retailers need packaging that preserves quality, meets regulatory standards, and appeals to increasingly savvy customers. One of the most important features in this equation is odor control. Our cannabis packaging is specifically engineered to be smellproof—designed to trap even the strongest aromas and keep them from escaping.
What materials do you use to make your packaging smellproof?
The effectiveness of packaging that’s smellproof starts with the materials. We source high-grade films and laminates that are designed to resist scent transmission. These are not just standard plastics—they are engineered specifically for cannabis and food-safe use.
Some of the materials used in our packaging include:
- Mylar (biaxially-oriented polyethylene terephthalate) – Known for its barrier strength, light resistance, and durability
- Foil laminates – Add another layer of protection against scent, moisture, and air
- Polyethylene and polypropylene linings – Help preserve freshness while preventing terpene transfer
- Multi-layer films – Bonded together to enhance odor-blocking without compromising flexibility
These materials are carefully tested and paired with closures that lock in the product’s aroma, making sure scent doesn’t escape even after the seal is broken and resealed multiple times.
How do seals and closures affect smellproof performance?
One of the most overlooked elements in cannabis packaging is the seal. Even the best barrier materials can’t work properly if the closure allows air or vapor exchange. That’s why Black Unicorn’s smellproof packaging includes high-performance seals and closures to ensure security from every angle.
Our options include:
- Heat-sealed tops – Ideal for dispensaries and processors; this creates a tamper-evident, airtight seal until the consumer opens it
- Dual-track zippers – Provide a tight reseal after opening, maintaining odor control for multi-use products
- Gusseted seams – Designed to hold shape and reinforce the seal, preventing stretching or breaking under pressure
- Child-resistant zippers – Combine smellproof security with compliance, especially useful for pre-roll multipacks or edibles
A good closure does more than lock in scent—it also supports shelf life, protects potency, and delivers a better experience for the end user.
What cannabis products benefit most from smellproof packaging?
While almost every cannabis product benefits from odor protection, some are especially vulnerable to scent leakage. Our packaging is particularly effective for:
- Flower and pre-rolls – Known for strong terpene profiles, these products require robust containment
- Infused edible packaging – Items like cannabis chocolates or gummies can emit odor through oil or flavor release
- Resin, rosin, and wax concentrates – These can produce strong, lingering aromas even in small quantities
- Multi-unit packs – Products that contain several pieces or servings need secure reclosure and lasting odor control
Our packaging is designed to address each of these formats while offering flexibility in size, style, and branding options.
What are the real-world benefits of smellproof cannabis packaging?
Our odorproof packaging doesn’t just keep the air clear—it plays a strategic role in retail success, customer satisfaction, and compliance. The right packaging can enhance your product’s performance in several ways.
Some key advantages include:
- Preservation of potency and freshness – Trapped scent often means trapped terpenes, which are key to both flavor and effect
- Discreet transportation – Your customers want to take their cannabis home without drawing unwanted attention
- Improved customer trust – Packaging that keeps aroma inside signals quality and professionalism
- Stronger retail relationships – Store owners appreciate packaging that helps them meet local odor control regulations
- Reduced product returns – Cannabis that smells too strong—or smells off—often gets rejected or returned. Smellproof bags reduce that risk
The containment of odor isn’t just about aroma—it’s a form of quality control. And in cannabis, quality sells.
Does smellproof packaging help with branding?
Absolutely. Smellproof packaging enhances branding by preserving the user’s first sensory experience: the scent. A bag that leaks scent before the customer opens it weakens the impact of that initial “open and inhale” moment that so many buyers anticipate.
Black Unicorn’s smellproof packaging options are designed to showcase your brand while protecting the product. Our offerings include:
- Printed pouches with matte, gloss, or soft-touch finishes
- Full-color art across both front and back panels
- High-resolution printing that resists smudging and fading
When your product smells fresh only when it should—when it’s first opened—it creates a better impression. That builds loyalty and increases word-of-mouth appeal.
Can odorproof packaging meet compliance standards?
Yes. In many areas, cannabis regulations include odor control. Dispensaries may be required to store products in packaging that does not allow aroma to escape. Smellproof packaging helps retailers meet these standards while also improving operational efficiency.
With Black Unicorn’s solutions, your packaging can:
- Reduce in-store odor build-up, which can cause compliance issues or complaints
- Support safe transportation in regulated states or provinces
- Lower exposure during delivery or restocking by minimizing scent leakage
- Help prevent theft or tampering by eliminating scent trails
We build our odorproof packaging with these real-world use cases in mind, so you don’t have to compromise between style and legality.
Can customers still reseal the smellproof bags?
Yes. Most of our smellproof packaging includes resealable closures that preserve odor control after opening. This is especially useful for multi-use items like flower, gummies, or pre-rolls. Once the top seal is broken, the inner zip-lock or child-resistant zipper takes over.
The resealability of our packaging offers:
- Longer-lasting freshness
- Better daily use experiences for consumers
- More discreet storage at home
- A higher perceived value for the product
We also offer single-use formats for dispensaries that prefer tighter control over first-time opening or are working with sample sizes.
What sizes and styles are available?
Our smellproof packaging is available in a variety of shapes, sizes, and closures to fit nearly every cannabis product. Whether you're packaging a single pre-roll or a full ounce of flower, we have options that combine aroma control with style and function.
Common formats include:
- Small mylar pouches for joints and samples
- Medium bags for eighths and edibles
- Large stand-up pouches for multipacks or bulk flower
- Custom-shaped pouches and die-cut window options
- Vertical or side-load entry bags with resealable options
