Cannabis Packaging Maryland. Compliant. Factory-Direct.

Maryland legalized adult-use cannabis on July 1, 2023, when the Cannabis Reform Act took effect. The state's medical program has operated since 2013, making it one of the earlier medical states on the East Coast. The Maryland Cannabis Administration (MCA), formerly the Maryland Medical Cannabis Commission, oversees both programs and enforces packaging standards that are specific about container construction.

Maryland's rigid container requirement for extracts and oils is the detail that catches packaging suppliers off guard. Most states say "opaque" and leave it at that. Maryland says opaque AND rigid with a rigid bottom. That eliminates thin mylar bags for concentrate products and requires specific container engineering. I've helped brands redesign their entire concentrate packaging line to meet this requirement.

Legal Status of Cannabis in Maryland

Maryland operates dual adult-use and medical programs under the MCA. Adult-use sales launched July 1, 2023, following voter approval of Question 4 in November 2022. The state generated approximately $250 million in adult-use sales in its first 12 months, exceeding initial projections.

The medical program serves over 30,000 registered patients and has been operational for over a decade. Medical cannabis is exempt from the state sales tax, while adult-use products carry a 9% state sales tax plus applicable local taxes. As of 2026, Maryland has over 100 licensed dispensaries.

The market is growing as new licenses are issued, particularly for social equity applicants. Maryland has prioritized diversity in licensing, and many new dispensary operators are entering the market for the first time. These operators need packaging partners who can guide them through compliance requirements — which is where we come in.

Maryland's adult-use market launched with strong consumer demand, generating over $25 million in sales in the first month alone. The state has since seen steady month-over-month growth. By 2024, combined medical and adult-use sales exceeded $500 million, and the MCA projects continued growth as more dispensaries open.

The Maryland market benefits from its location between Washington DC and Pennsylvania. DC residents can purchase adult-use cannabis in Maryland, and many Pennsylvania medical patients travel to Maryland for product availability. This cross-border dynamic creates demand for brands that can supply consistent packaging across the region.

Child-Resistant Requirements in Maryland

Maryland requires child-resistant packaging for all cannabis products. While Maryland does not explicitly cite CPSC 16 CFR 1700.20 by statute, the CR standard in practice aligns with the federal protocol. Packaging must prevent children under five from accessing the contents within a reasonable time frame.

Tamper-evident packaging is also required. The consumer must be able to identify whether the package has been opened or compromised before purchase. Tear strips, breakaway zippers, and heat-sealed closures with visible evidence of entry all satisfy this requirement.

We provide 16 CFR 1700.20 test certification for all CR packaging we sell in Maryland. Even though Maryland's statute doesn't name the specific standard, our documentation exceeds the requirement and satisfies any inspector. View our child-resistant mylar bags with full certification.

Maryland's CR requirement applies to all product categories including topicals and tinctures, which some states exempt. If you're selling a cannabis-infused lotion or oil in Maryland, it must be in CR packaging. This is a common oversight for brands that sell topicals — they assume CR only applies to flower and edibles, but Maryland's rule is universal.

The MCA also requires that CR packaging maintain its child-resistant properties for the shelf life of the product. A CR zipper that degrades after 6 months doesn't meet the requirement if the product has a 12-month shelf life. We test our CR zippers through accelerated aging to ensure they maintain child-resistance throughout the product's usable life.

Opacity Requirements — Universal Mandate

Maryland requires opaque packaging for all cannabis products across every category. Flower, edibles, concentrates, topicals, and tinctures must all be packaged in opaque materials that prevent the product from being visible through the packaging.

The opacity mandate in Maryland is universal — there are no exceptions for specific product types. This is stricter than states that only require opacity for edibles or flower. If you're selling any cannabis product in Maryland, the packaging must be opaque.

Our opaque mylar bags use a multi-layer construction with an opaque inner film that blocks 100% of visible light. This prevents both UV degradation and visual identification of the product. View custom mylar bags in opaque finishes for all sizes from 1g to 1lb.

For brands selling in Maryland, the opacity requirement means you cannot use clear window patches, transparent label sections, or any packaging element that allows visual identification of the product. This includes partially opaque bags where the product silhouette is visible through the material under bright light. The MCA tests opacity by holding the package up to a standard light source and checking for any visible product.

Rigid Container Requirements for Extracts & Oils

This is where Maryland stands apart from most states. The MCA requires that extracts, oils, and concentrate products be packaged in rigid opaque containers with rigid bottoms. The purpose is to prevent leakage — thin, flexible packaging like standard mylar bags does not meet this requirement for concentrate products.

Rigid containers that meet Maryland's requirement include:

• Glass concentrate jars with opaque or UV-blocking glass and CR lids
• Rigid plastic containers with opaque walls and rigid bottoms
• Metal tins with opaque construction and CR closures

The rigid bottom requirement means the container cannot be squeezable. A container that is rigid on the sides but has a flexible bottom does not meet Maryland standards. The entire container, including the bottom, must be rigid enough to prevent the product from leaking under normal handling conditions. This is an engineering specification, not a preference.

Our concentrate jars and dab containers are available in rigid, opaque construction that meets Maryland's requirements. We also offer CR-certified lids for these containers.

The rigid container requirement applies specifically to extracts, oils, waxes, shatters, and other concentrate products. Flower can still be packaged in resealable mylar bags, and edibles can use standard opaque packaging as long as it meets CR and opacity requirements. The rigid rule is narrow — it targets products that could leak through flexible packaging under normal handling conditions.

Brands that sell both flower and concentrates in Maryland need two different packaging types: flexible mylar bags for flower and rigid containers for concentrates. This means your packaging supplier needs to offer both product lines with CR certification. We produce both, so you can source all your Maryland packaging from one supplier with one all-in quote.

Labeling & What's Prohibited

Maryland requires cannabis packaging labels to include THC potency, CBD content, net weight, batch number, and warning statements. The state universal symbol must be displayed. Packaging must also include the licensee information and harvest or production date. For edibles, allergen information and serving size must be clearly marked.

Maryland prohibits packaging that is attractive to minors. No cartoons, no imagery appealing to children, and no packaging that resembles commercial food or candy. The MCA evaluates packaging designs for youth appeal during product approval, and designs that don't pass cannot be sold.

False or misleading health claims are prohibited. Medical cannabis products can reference qualifying conditions but cannot claim to treat, cure, or prevent disease without FDA approval. Non-compliant packaging can result in product seizure, fines up to $10,000 per violation, and license suspension.

Maryland's labeling rules also require that the universal symbol be printed in a specific size relative to the package. Small packages need proportionally smaller symbols, but there is a minimum size below which the symbol is not considered readable. We design labels that meet Maryland's size requirements for every package format.
