Child-resistant containers is a broader term than child-resistant packaging. Packaging often implies a complete branded retail unit. Containers refers to the primary vessel itself: the jar, the tube, the tin, the bag. For buyers in the early stages of evaluating CR packaging options, understanding the container landscape before committing to any specific format is the right sequence.
This guide covers the full CR container landscape by type, what each type is designed for, the size range available within each type, and what to confirm before sourcing.
Why the Container Decision Comes Before Everything Else
The container determines the decoration method available to you. The container determines the barrier performance the product will receive. The container determines the shelf presence and sensory signals the product communicates. The container determines the MOQ structure and the lead time. And the container determines which CR closure mechanisms are viable, which in turn affects which certification standards apply.
Changing the container after artwork is approved means restarting decoration. Changing the container after production runs means writing off inventory. The container decision is the one that cascades into everything downstream, which is why it belongs at the beginning of the sourcing process rather than at the end.
The sequence that avoids expensive corrections: product specifications first (dimensions, fill weight, barrier requirements), container type second, specific format and size third, decoration and label planning fourth.
CR Jars
Jars are the widest-mouth CR container type, appropriate for products accessed by hand or scoop rather than dispensed through a closure.
Glass CR jars are the premium standard for cannabis flower, concentrates, and edibles. Glass is completely inert: no material interaction with terpenes, cannabinoids, or active ingredients. No off-gassing. No sorption of active compounds over product contact. Amber glass provides UV blocking. Clear glass provides product visibility where state opacity requirements permit.
Glass CR jars are available in small concentrate volumes (TPC’s Square Glass Concentrate Jar at 5ml, 7ml, and 9ml) through larger flower volumes. The CR mechanism is in the push-and-turn or squeeze-and-turn lid, which must be tested as a system with the specific jar neck finish.
Plastic CR jars are the cost-efficient standard for high-volume flower, edibles, and accessible-price-point SKUs. Available in a wide range of volumes. Lighter than glass, lower per-unit cost, and available in more dimensional configurations. The CR lid mechanism is the same push-and-turn design as on glass jars. Appropriate for brands where per-unit packaging cost is the primary constraint.
Tin jars (ASTM certified, 90ml capacity at TPC) are a metal alternative for brands wanting an airtight, fully light-blocking jar format. Well-suited to edibles and concentrate formats where a metal container communicates premium and the airtight seal is a product quality priority.
What to confirm before ordering CR jars:
Volume match. The jar volume should accommodate the fill weight with appropriate headspace for the CR lid to engage correctly. A jar that is significantly oversized for the fill creates product movement and an unfavorable first-open presentation.
Lid-to-neck compatibility. The CR lid must be specified for the exact neck finish (diameter and thread profile) of the jar. Confirm this explicitly in writing, not by visual inspection.
Opacity compliance. Most state cannabis regulations require opaque packaging for retail cannabis products. Amber glass provides UV blocking but may not satisfy opacity requirements depending on how the state defines the term. Clear glass does not satisfy opacity requirements. Confirm your state’s specific language before specifying a glass jar.
CR Tubes
CR tubes are the standard format for cannabis pre-rolls and can accommodate single units or small multi-packs depending on the tube diameter and length.
Glass CR tubes with push-and-turn caps are the premium single pre-roll format. Product visibility, inert material, clean minimal presentation. Available with short cap, standard cap, and aluminum overshell cap variants. On the aluminum overshell: the CR mechanism is plastic; the aluminum is a decorative layer applied over the plastic cap.
Aluminum CR tubes provide full light blocking and an airtight seal in a metal format. Single-unit and multi-pack (K29F) configurations available. Eco-friendly and fully recyclable.
Plastic CR tubes are the volume standard for accessible-price-point pre-roll packaging. Push-and-turn and squeeze-and-pull closure options. The lowest per-unit cost in the tube category.
CR tubes for pre-rolls are specifically sized to pre-roll dimensions. Tube length and diameter must match the pre-roll spec precisely. A tube that does not engage the CR closure correctly because the pre-roll sits proud of the fill line is a compliance failure, not just a fit issue.
Note: squeeze tubes for topicals (lotions, creams, balms) are a different product category from CR tubes for pre-rolls. Topical squeeze tubes with CR screw caps live in the CR Topical Packaging category, not the CR Tubes category. This distinction matters for sourcing, because the CR mechanism, fill line equipment, and certification standard differ between the two.
CR Tins
CR tins are rigid metal containers with engineered closure mechanisms. They are the premium format in the cannabis pre-roll and multi-pack category and are increasingly used for flower, edibles, and vape applications.
Two closure systems are available at TPC:
Snap closure tins (V5 and V5E) use TPC’s corner-press mechanism. The user presses and squeezes the two bottom corners simultaneously, which releases the upper corners to open the lid. No external button, no visible hardware. The tin body is the closure mechanism. Airtight and watertight. Certified to 16 CFR §1700.20.
Squeeze/hinge-lid tins (V1, V1A, V4A, V7) use a squeeze-to-open CR mechanism with a hinged lid that stays connected to the tin when open. Available across multiple sizes for different pre-roll counts and product configurations. Dual ASTM and 16 CFR §1700.20 certified.
All TPC CR tin formats support full lithographic printing, custom interior insert trays or foam configurations per project, and a range of decoration finishes. The metal tin body is recyclable; note that insert trays and other interior components are separate materials.
The size selection for CR tins is driven by the product dimensions and count configuration:
V5 (74x58x20mm): Standard pre-rolls, 1 to 5 packs. V5E (95x57x20mm): King-size pre-rolls and larger multi-packs. V1 (102x98x14mm): 5 to 7 pack, maximum lid surface. V1A (103x98x17mm): All-metal, deeper cavity. V4A (101x63x15mm): Slim 3 to 5 pack. V7 (102x97x27mm): Up to 14 pre-rolls or high-volume edible configurations.
CR Bags (Flexible Containers)
CR mylar bags are flexible rather than rigid, which classifies them differently from the container types above but makes them the dominant CR format by volume in the cannabis market.
CR bags use a slide-lock or press-and-pull closure mechanism for child resistance. The multi-layer foil-laminate film construction provides barrier performance against oxygen, UV light, and moisture. The CR certification applies to the bag-and-closure combination as tested.
Available from 1g through 28g fill weights. Custom printing in matte, gloss, soft-touch, metallic, and specialty finishes. Opaque by default in the standard foil-laminate construction.
The considerations for CR bags are distinct from rigid containers: fill size and bag dimensions need to be matched for the specific product (excess headspace creates product movement; insufficient headspace affects closure engagement). The closure mechanism must be evaluated over repeated cycles. Opaque requirements in most cannabis markets are satisfied by the standard construction.
CR Topical Containers
The CR topical packaging category covers a distinct set of container types designed for formulations that are dispensed rather than accessed directly: squeeze tubes, pump bottles, roll-on bottles, and dropper bottles.
These are the appropriate formats for cannabis topicals, CBD tinctures, medicated creams, and regulated wellness liquid formulations. They are not interchangeable with the jar, tube, and bag formats used for flower, edibles, concentrates, and pre-rolls.
Key formats in this category:
CR Squeeze Tube (ASTM F1702 certified, 30ml/60ml/90ml, 3-layer or 5-layer aluminum laminate or all-plastic).
CR Airless Pump Bottles (standard, large format, and mono-material configurations, all 16 CFR §1700.20 certified).
CR Glass Dropper Bottle (for tinctures and sublingual oils).
CR Roll-On Bottle and Clinical Format Roll-On.
CR Lip Balm Tube and CR Syrup Bottle for additional regulated wellness applications.
Sourcing Checklist: What to Confirm Before Ordering Any CR Container
Regardless of which container type is appropriate for your product, the same sourcing questions apply:
Does the container dimensions match your product specification (fill weight or volume, dimensional clearances, count configuration)?
Does the supplier have a third-party laboratory test report confirming 16 CFR §1700.20 certification for the specific container and closure being ordered?
Have you confirmed which closure mechanism the CR certification applies to, and is that the same closure being supplied?
Can the supplier provide written confirmation at each reorder that the current production run matches the tested specification?
Have you received a pre-production sample and evaluated it with your actual product, including closure function over 20 to 25 cycles?
Does the container satisfy any additional state-specific requirements for your distribution markets (opacity, resealability, individual dose marking)?

Frequently Asked Questions
What is the difference between a CR container and CR packaging? Container refers to the primary vessel (the jar, tube, tin, bag). Packaging refers to the complete retail unit, which may include the container plus label, insert, and any secondary packaging. In sourcing conversations, the container decision comes first because it determines the decoration method, barrier performance, closure mechanism, and MOQ structure that everything else is built around.
Which CR container type is best for cannabis concentrates? Glass is the standard material for concentrates because it is completely inert and has no material interaction with terpene compounds or active ingredients. TPC’s Square Glass Concentrate Jar is available in 5ml, 7ml, and 9ml, certified to 16 CFR §1700.20, with an airtight liner cap. Tin jars are an alternative for brands preferring metal. Plastic containers are generally not recommended for premium concentrate products because of potential terpene interaction over extended contact.
What is the minimum order quantity for CR containers at TPC? MOQ varies by container type. Most CR tins, tubes, and bags start at 5,000 units. CR glass concentrate jars start at 10,000 units. CR topical formats including squeeze tubes and dropper bottles typically start at 10,000 units. Contact TPC for current MOQ and lead time for any specific container format.
Can the same CR container be used across multiple cannabis SKUs? Yes, this is a common approach for brands with multiple SKUs in the same product category. A single tin format with SKU-specific labels allows the brand to consolidate volume at the format level rather than running separate decorated production for each SKU. Pre-roll insert trays are custom-engineered per project to the specific pre-roll dimensions, so a multi-SKU tin program may have the same tin exterior with different interior configurations per product.
How do I match a CR jar lid to the correct jar? By neck finish specification. The neck finish defines the inner diameter and thread profile of the jar opening. Common specifications include 38/400, 53/400, and 70/400. The CR lid must be specified for the exact neck finish of the jar. Confirm this explicitly with the supplier in writing before ordering. Visual matching is not sufficient because similar-looking neck finishes can have different thread profiles that affect closure engagement and CR mechanism performance.
