Glass cannabis jars affect more than product appearance. They also influence odor control, light protection, sealing, child resistance, and filling efficiency. For cannabis brands, cultivators, and packaging distributors, supplier selection should go beyond unit price. Buyers should also confirm jar-and-closure compatibility, actual fill capacity, customization processes, compliance documentation, and long-term replenishment capability.
This article presents eight manufacturers and suppliers with strong visibility in searches related to “glass cannabis jar” and “wholesale cannabis glass jars,” together with relatively complete product specifications and company information. EasyJars is placed third according to the editorial arrangement of this article.
Search results vary by time and location. The order below does not represent third-party certification or an absolute quality ranking. Buyers must still complete their final assessment through samples, documentation, and practical testing.
What Should You Compare When Selecting a Glass Cannabis Jar Supplier?
A reliable supplier should be able to explain the complete packaging system rather than simply provide an empty glass jar. Buyers should compare the following points:
- Capacity and actual fill weight: The same nominal volume may hold different amounts depending on flower density, bud size, and required headspace.
- Jar-and-closure compatibility: The neck dimensions, thread, liner, and closure structure work together to determine sealing performance.
- Child resistance: Require test documentation that corresponds to the complete jar-and-closure combination. Do not rely only on the words “CR lid.”
- Light protection: Clear glass displays the product, while amber, black, tinted, or coated glass is better suited to products that require reduced light exposure.
- Customization methods: Common options include screen printing, UV printing, hot stamping, spray coating, frosting, etching, labels, and custom molds.
- MOQ and replenishment model: In-stock wholesale products suit smaller orders, while factory customization is more appropriate for brands that require a distinctive shape, stable specifications, and ongoing replenishment.
- Sampling and quality control: Use the actual flower to test fill capacity, closure engagement, label placement, drop-resistant packing, and transport protection.

1. Roetell
Roetell is a glass container manufacturer based in Jiangsu. It has glass production, existing molds, closure-support capabilities, and glass-finishing resources, serving brand owners, wholesalers, and other packaging suppliers.
Its glass cannabis jar range includes common capacities such as 60, 90, 110, and 180 ml, with the broader selection extending to approximately 1000 ml. Available appearance directions include clear, black, and dark violet glass, and specified jar models can be paired with child-resistant closures.
In addition to existing jar formats, Roetell offers screen printing, color spraying, frosting, labeling, electroplating, and 3D printing. The manufacturer lists a minimum order quantity of approximately 3,000 pieces for surface customization on certain existing jars, while the stated MOQ for fully customized glass jars is 50,000 pieces.
Roetell is therefore better suited to brands or packaging distributors with stable sales, the ability to purchase in larger quantities, and a need for consistent specifications and long-term replenishment.
Best suited for: Medium- to large-volume projects, dark or UV-protective appearances, and ongoing replenishment.
Confirm before ordering: Stock products and new molds have different MOQs. Confirm sampling, tooling, closure documentation, and lead times separately.
2. YPC Packaging
YPC Packaging positions itself as an integrated glass packaging manufacturer and supplier and states that its production system covers glass, closures, and downstream finishing processes.
Its cannabis jar range covers round, square, straight-sided, and wide-mouth structures, with listed capacities including 3 oz, 4 oz, 5 oz, 8 oz, 10 oz, and 16 oz. Specified jar models can be paired with black, white, or dome-style child-resistant closures, while available appearance directions include clear, amber, and matte black.
YPC Packaging’s advantage is its relatively broad selection of existing jar models. Buyers can begin with an established specification and then add printing, labels, or color treatment, reducing the time required to develop a structure from the ground up.
The manufacturer is suitable for flower packaging projects that need to compare multiple capacities and shapes while retaining a degree of brand customization. Buyers should not select a jar solely by its ounce or milliliter rating. Actual flower should be used to confirm internal space, fill weight, and closure depth.
Best suited for: Multi-SKU product lines, square or wide-mouth glass jars, and bulk brand customization.
Confirm before ordering: The supported closure, liner, certification documents, and minimum order quantity may vary by jar model.
3. EasyJars
EasyJars is a cannabis packaging production factory in Guangzhou. Its core products include flower jars, concentrate containers, pre-roll tubes, and Pop-Vac packaging.
Its glass cannabis jar capacities range from 30 to 1000 ml. Existing directions include round, square, triangular, and hexagonal forms, while new molds can also be developed around capacity, grip, neck finish, and a brand-specific shape. Glass options include clear, tinted, frosted, coated, and thick-wall effects.
EasyJars can coordinate the jar body, child-resistant closure, screw-cap liner, and Pop-Vac vacuum closure as one complete packaging system. This approach helps reduce compatibility problems among the jar, neck finish, closure, and liner.
Branding processes include screen printing, UV printing, hot stamping, spray coating, water transfer printing, heat transfer printing, etching, electroplating, and labels. Logos can be applied to the jar body, closure, and other areas suitable for printing or decoration.
EasyJars’ main production factory is located in Guangzhou. According to company information provided by EasyJars, it also has a local office and warehouse in New York, making it suitable for buyers that need factory customization capabilities together with communication support for the U.S. market.
Best suited for: Distinctive shape development, integrated jar-and-closure customization, and multiple logo and surface-finishing processes.
Confirm before ordering: Provide the target fill weight, actual flower, closure requirements, destination, and artwork so that the sampling and mass-production plan can be determined.
4. Finished Goods
Finished Goods is a packaging project supplier and integrator based in Los Angeles. It should not be described directly as a glass-melting factory.
Its child-resistant glass jar series includes 1, 2, 3, 4, 5, and 6 oz sizes, together with 10 oz Slim and 10 oz Wide formats. Jar-body options include clear, black-pigment, white-pigment, and custom-painted glass. Applications include flower, edibles, topicals, and CBD products.
Finished Goods lists ASTM D3475 and CPSC 16 CFR 1700 child-resistant information for this glass jar series. It also offers induction seals, PTFE, PE, and pressure-seal liner directions.
This supply model is attractive to brands that prioritize compliance documentation and local U.S. project communication. Buyers should nevertheless confirm that the test report covers the exact jar, closure, and liner combination they intend to purchase. Test information for one product series should not be extended automatically to other SKUs.
Best suited for: Regulated U.S. markets, projects requiring child-resistant documentation, and standardized 1-10 oz product lines.
Confirm before ordering: The exact SKU covered by the certification, the MOQ for custom colors, and liner compatibility with the product.
5. King Custom Cones
King Custom Cones is a Houston-based wholesale supplier best known for pre-rolled cones and pre-roll packaging. Glass cannabis jars form part of its flower packaging range, and the company should not be described as a specialized glass jar manufacturer.
The range includes clear, UV amber, and colored options that can be paired with child-resistant, tamper-evident, or continuous-thread closures. Existing products include 2 oz and 3 oz jars, as well as elongated glass jars suitable for multiple pre-rolls. Certain products are sold in quantities of 100 or 200 pieces.
The supplier’s advantage is a relatively accessible threshold for purchasing in-stock products, together with tiered volume pricing. It is suitable for brands that have not yet reached the order quantities required for large-scale factory customization.
For projects that need an urgent launch, replenishment, or validation of a new specification, an in-stock glass jar with a label is usually faster than developing a new mold. A stock jar’s stated capacity does not automatically equal a fixed flower weight, so actual flower must still be used to test fill weight, headspace, and sealing.
Best suited for: Smaller quantities, U.S. stock supply, rapid product testing, and replenishment.
Confirm before ordering: Inventory, actual lead time, closure type, whether the closure is included, and the separate MOQ for customization services.
6. Green Tech Packaging
Green Tech Packaging is a wholesale supplier of food, hemp, and cannabis packaging based in Santa Fe Springs, California. Its core strengths are in-stock inventory and volume replenishment rather than glass jar production.
Its products include 4 oz child-resistant glass flower jars positioned for approximately 7 g, as well as 5 ml and 9 ml small glass concentrate jars. Related products include tamper-evident shrink bands, pressure seals, humidity-control packs, and state-compliant labels.
Green Tech Packaging operates more like a comprehensive packaging wholesaler. Buyers can source glass jars, sealing components, labels, and other retail consumables together, reducing the number of suppliers involved in routine replenishment.
This centralized purchasing model is convenient for dispensaries, processors, and buyers that require ongoing small-volume replenishment. If a project requires an exclusive shape, complex coating, or extensive structural development, buyers should confirm the company’s customization scope, partner factory, and division of quality responsibility in advance.
Best suited for: In-stock dispensary purchasing, flower and concentrate replenishment across multiple categories, and consolidated accessory sourcing.
Confirm before ordering: Inventory allocation, volume discounts, the scope of custom printing, and child-resistant documentation.
7. STD Glass
STD Glass is a glass packaging manufacturer and bulk supplier based in Shandong, serving fragrance, home, and cannabis packaging projects.
Its cannabis jar directions include clear, white, black, frosted, and other tinted glass. It supports screw closures, child-resistant closures, and custom closure solutions. Existing products include 5 oz clear jars, thick-wall jars, and glass containers designed with a light-protective appearance.
STD Glass provides customization for dimensions, colors, logos, labels, frosting, coating, and closure appearance. It is suitable for buyers that want to work directly with glass manufacturing and OEM services.
As with other cross-border factory projects, buyers must define glass weight, dimensional tolerances, neck specifications, closure torque, transport packaging, and inspection criteria before mass production. Orders should not be approved solely from product images.
If a new mold is required, buyers should also confirm tooling costs, mold ownership, the number of sample revisions, and conditions for future replenishment.
Best suited for: Factory-scale purchasing, OEM colors and surface finishes, and export projects.
Confirm before ordering: Consistency between the sample and mass production, mold ownership, breakage-prevention packaging, and quality-acceptance standards.
8. Feel U / Canna Custom Supply
Feel U / Canna Custom Supply is a Shenzhen-based OEM/ODM cannabis packaging manufacturer and supplier. Its main capabilities cover Mylar bags, paper boxes, labels, jars, and pre-roll tubes.
Its glass jar program lists flower-fill directions of 3.5 g, 7 g, 14 g, and 28 g, with clear, amber, and UV-protective glass options. Closure directions include child-resistant screw caps, standard screw caps, pop-top caps, and cork lids, together with airtight, smell-proof, and tamper-evident solutions.
Feel U states that selected custom projects can start at 100 pieces and offers label layout, mockup, and prepress-file support, making it more suitable for startups and new-product trials.
The company’s description of its own production lines mainly concerns Mylar bags and paper boxes. This does not establish that all glass jars are melted in-house. When sourcing glass jars, buyers should further confirm the origin of the jar body, the party responsible for closure testing, and the division of quality responsibility.
Lower MOQs generally rely more heavily on existing jar models and label-based decoration. If a project requires a custom glass mold, special color, or complex closure structure, the quantity, price, and production time will usually need to be recalculated.
Best suited for: Startups, low-volume trial runs, and rapid customization based primarily on labels.
Confirm before ordering: The specific processes covered by the 100-piece MOQ, sample fees, mass-production lead time, and closure test documentation.
Which Type of Supplier Is Better Suited to Your Project?
Different purchasing stages are better suited to different types of suppliers:
- Market testing or a small-volume launch: Prioritize King Custom Cones, Green Tech Packaging, or Feel U, which offer in-stock products or relatively low MOQs.
- U.S.-based projects and child-resistant documentation: Focus on Finished Goods and other suppliers that can provide test documentation for specific SKUs.
- Large-volume purchasing for established brands: Roetell, YPC Packaging, and STD Glass offer stronger glass-manufacturing and bulk-customization capabilities.
- Custom shapes, Pop-Vac closures, and multiple branding processes: EasyJars is better suited to developing the jar, closure, and decoration as one complete packaging system.
What Information Should You Prepare Before Contacting a Supplier?
To obtain quotations that can be compared directly, send the same project information to every shortlisted supplier:
- Product type and target fill weight, such as 3.5 g, 7 g, or 28 g of flower;
- Expected capacity, jar shape, and dimensional limitations;
- Requirements for clear, amber, black, frosted, or custom-colored glass;
- Requirements for child-resistant, standard screw, or Pop-Vac closures;
- Logo files, label dimensions, and the intended decoration process;
- Initial order quantity, estimated annual volume, and destination;
- Required test documentation, sample quantity, and lead time;
- Transport packaging, inspection standards, and an acceptable process for handling breakage.
The more complete the information a supplier receives, the more closely its pricing, samples, and production recommendations will reflect the actual project. Asking only for a general unit price usually does not capture the full cost of closures, liners, printing, packing, and transportation.
How Can You Verify Whether a Supplier Is Reliable?
Inspect samples
Use the actual flower to test fill weight, access space, closure operation, sealing performance, and label placement. Do not evaluate only the appearance of an empty jar.
Review child-resistant documentation
Confirm that the jar body, neck finish, closure, and liner in the documentation match the combination you intend to purchase. Test documentation for a closure alone does not necessarily prove that the final packaging combination meets the requirements of the target market.
Define production responsibility
Determine whether the supplier is a glass manufacturer, a packaging integrator, or an in-stock wholesaler. Each company type has advantages, but buyers must establish who is responsible for the jar body, closure, printing, inspection, and after-sales support.
Establish quality standards
Record glass weight, dimensional tolerances, acceptable color range, logo placement, surface-defect criteria, closure torque, and transport-packaging method in the purchasing agreement or specification sheet.
Test before scaling production
Validate the product through samples or a small order before moving into large-scale purchasing. For new molds or complex coatings, retain a mutually approved reference sample as the basis for mass-production acceptance.
Conclusion
When selecting a glass cannabis jar supplier, the priority is not simply finding the lowest quotation. Buyers must confirm whether the supplier can consistently provide compatible jar bodies, closures, liners, decoration, and quality documentation.
In-stock wholesale supply can help brands launch quickly. Packaging integrators are better suited to projects that need local communication and multi-category coordination, while glass manufacturing factories are more appropriate for distinctive structures, stable specifications, and long-term bulk replenishment.
If your project requires capacities from 30 to 1000 ml, different shapes, child-resistant closures, Pop-Vac vacuum closures, or custom surface finishes, send the target fill weight, purchasing quantity, and artwork to EasyJars. Its factory team can recommend a suitable glass jar solution based on the actual application.
