In the regulated cannabis market, packaging must do more than store the product, it needs to protect potency, meet compliance, and support sustainability. One format that’s winning over eco-conscious cannabis brands is the 7g glass jars design.

These compact, recyclable containers are becoming the go-to choice for cannabis concentrates, extracts, and small flower portions. With their premium feel, product protection, and smaller environmental footprint, they deliver both style and function.

Glass: The Technical Advantage

Glass remains a premium choice for cannabis packaging. Here’s why 7g glass jars stand out:

• Inert and non-reactive – No interaction with terpenes or cannabinoids, ensuring purity.
• Strong UV barrier – Amber and cobalt glass protect light-sensitive products.
• Heat-tolerant – Safe for sterilization, allowing reuse in compliant facilities.

Compared to 14g glass jars, the 7g option offers the same protection while using less material and being more portable, perfect for precise, small-batch cannabis products. 

Sustainability at Scale

Glass is endlessly recyclable and ideal for brands aiming to reduce waste.

• Lower material use – Smaller jars require fewer resources.
• High recycling value – Maintains quality after repeated recycling.
• Reduced shipping impact – Lighter weight helps cut transport emissions.

While 14g glass jars suit larger quantities, the 7g option is the greener choice for single-serve and micro-dosed cannabis.

Ideal Use Cases

Best uses for 7g glass jars:

• Single-dose cannabis extracts.
• Micro-dosing premium flower.
• Limited-edition or subscription cannabis products.

Best uses for 14g glass jars:

• Multi-use cannabis extracts.
• Larger flower portions for frequent users.

Offering both sizes creates a tiered product range that meets diverse consumer needs.

Manufacturing & Compliance Benefits

Both jar sizes integrate well with production systems:

• Compatible with automated filling lines for speed and precision.
• Flexible labeling for strain info and regulatory data.
• Available in tamper-evident and child-resistant designs for cannabis compliance.

For high-volume, small-dose products, the 7g jar is more cost-efficient, while 14g glass jars work best for full-use formats.

Premium Brand Presentation

Glass packaging communicates quality and professionalism.

• Custom finishes – Matte, gloss, or embossed labels for visual appeal.
• Elegant design – Durable feel and premium user experience.
• Consistency across SKUs – Cohesive branding from trial-size to large-size jars.

Cost-Benefit Overview
