Cannabis Packaging Montana. Compliant. Factory-Direct.

Legal Status

Montana legalized adult-use cannabis through Initiative 190 in November 2020. The Montana Department of Revenue's Cannabis Control Division (CCD) regulates both the adult-use and medical programs. Adult-use sales began January 1, 2022, making Montana one of the newer legal markets.

Montana's cannabis regulations are codified in the Montana Administrative Rules (MAR) under Title 42, Chapter 39. Packaging requirements appear in MAR 42.39.406 and apply to both medical cardholders and adult-use consumers.

The state has roughly 400 licensed dispensaries serving a population of about 1.1 million. Montana's market generated approximately $200 million in cannabis sales in 2024. The state's rural geography means packaging durability matters more here than anywhere—products ship long distances between producers and dispensaries across Big Sky Country.

Montana uses Metrc for seed-to-sale tracking. The Metrc UID must appear on every package label. The CCD inspects packaging during facility audits and product registration.

Montana's market has grown faster than expected. The state initially anticipated $130 million in annual sales but hit $200 million within two years of adult-use launch. That growth means regulators are scaling enforcement. The CCD has increased packaging inspections in 2024 and 2025.

One thing about Montana: the state initially had a residency requirement for cannabis business ownership, which was struck down in 2024. This change has brought new operators into the market, and many of them are learning Montana's packaging rules for the first time. The CCD is working to educate new licensees, but compliance is still the operator's responsibility.

Child-Resistant Requirements

Montana requires child-resistant packaging per CPSC standards under 16 CFR § 1700. All cannabis products sold at retail must be in CR packaging at point of sale. MAR 42.39.406 specifies ASTM D3475 as the certification standard.

Montana's CR requirements:

• CR packaging required for all retail cannabis products
• Tamper-evident features mandatory on all packaging
• CR certification documentation must be available for CCD inspection
• CR functionality must be maintained for the life of the product

Montana is strict about tamper-evident packaging. The tamper-evident feature must be visible and intact when the consumer receives the product. If the feature is broken or missing, the product is non-compliant. This means your packaging needs a visible seal that clearly shows whether the package has been opened.

Our child-resistant mylar bags meet Montana's CR and tamper-evident requirements. Each bag ships with full ASTM D3475 certification and tamper-evident tear strips.

Montana also requires that CR packaging protect products from contamination. This means the packaging must create a barrier against moisture, air, and contaminants. Mylar bags with heat-sealed edges and CR zippers meet this requirement. The contamination protection requirement is unique to Montana—most states specify CR and tamper-evident but don't explicitly require contamination barriers.

The CR certification documentation must be from a recognized testing lab. Self-certification is not accepted. CropPak provides third-party lab certification with every shipment, so you have the documentation ready when the CCD asks.

Opacity & Resealability

Montana requires opaque packaging for all cannabis products. Unlike some states that only require opacity for infused products, Montana requires opacity across the board. MAR 42.39.406 states that packaging must prevent visibility of the product from outside.

Resealability is mandatory. The packaging must allow consumers to reseal the package after opening to maintain product freshness and prevent contamination. The resealable feature must work in conjunction with the CR mechanism—closing the bag must re-engage the CR lock.

For liquid cannabis products, Montana has specific rules. Liquid products must be in containers that prevent leakage and maintain product integrity. The packaging must be designed so that the liquid does not come into contact with the CR mechanism, which could compromise functionality.

Liquid cannabis packaging in Montana must also be opaque. Clear liquid bottles, even with opaque caps, don't meet the requirement. The entire container must be opaque. If you're packaging tinctures or beverages, you need opaque bottles with CR-compatible closures.

Our custom mylar bags provide opaque, resealable, CR-compliant packaging for all Montana product types. For concentrates and extracts, we offer opaque containers with CR lids that maintain tamper-evident seals.

Montana's contamination protection requirement means your packaging needs to be durable enough for rural shipping conditions. Products traveling from Billings to Missoula go through temperature changes and rough handling. I recommend thicker mylar material (4.5 mil minimum) for Montana shipments. Standard 3-mil bags can crack in cold weather or puncture during rough transport.

The state's winter conditions also affect resealable zippers. Zippers can become stiff and difficult to engage at low temperatures. CropPak tests all zippers at temperatures down to -20°F to ensure they function in Montana winters. If your zipper doesn't reseal because it's frozen, your packaging is non-compliant.

Labeling & Universal Symbols

Montana requires the IICPS (Integrated Irradiated Cannabis Product Symbol) on all cannabis packaging. The symbol is a warning icon with a cannabis leaf that indicates the product contains cannabis. It must be clearly visible and permanently printed.

Required label elements under MAR 42.39.406:

• IICPS universal symbol
• Product name
• License number of cultivator or manufacturer
• Batch or lot number for Metrc track-and-trace
• Date of harvest or production
• Net weight or volume
• THC and CBD content (total and per serving)
• Required health warnings
• Ingredient list
• Allergen disclosures
• Serving size and servings per package
• Government warning statements

Montana requires specific government warning statements on labels, including warnings about impaired driving, risks during pregnancy, and mental health risks. The exact wording is specified in the MAR.

Labels must be in English, permanently affixed, and in a font no smaller than 6-point. The IICPS symbol must be at least 0.5 inches in size.

The CCD reviews packaging during product registration. If the IICPS symbol is missing or the government warnings don't match the specified wording, the product gets held. I've seen Montana reject packaging because the warning text was paraphrased rather than using the exact specified language.

Metrc UIDs must be scannable on the label. The CCD checks that the UID matches the product in the system. If there's a mismatch, the product is held until the label is corrected.

What's Prohibited

Montana prohibits:

• Packaging that appeals to children (cartoons, characters, toy-like shapes)
• Imitation of candy or food branding
• Clear or transparent packaging (opacity required for all products)
• Packaging without CR and tamper-evident features
• Non-resealable packaging
• Claims of health or medical benefits
• Packaging that resembles alcohol or tobacco branding
• Use of the word "candy" on labels
• Images of minors consuming cannabis

Montana's CCD is thorough in reviewing packaging. I've seen Montana reject packaging for using cartoon-style fonts and bright colors. Stick to professional design with muted color palettes.

The state also prohibits packaging that makes health claims. You cannot state or imply that cannabis treats, cures, or prevents any disease. This includes implied claims through imagery—a label showing a person in pain relief next to a cannabis product could be interpreted as a health claim.

How CropPak Helps

Montana's packaging rules are comprehensive—opacity required for everything, resealability mandatory, contamination protection built in. I've worked with Montana operators who lost shipments because their packaging didn't survive the drive from producer to dispensary in winter conditions.
