Cannabis Flower Jars

Our cannabis flower jars act as effective barriers against extreme temperatures and the growth of bacteria while removing the smell of cannabis. Having complete facilities and access to durable glass materials, Apackaging can manufacture numerous cannabis flower jars that can be customized according to your design and requirements.

Durable Glass Flower Jars: Keep Your Cannabis Fresh and Protected

Cannabis flowers are like tiny chemistry labs—they produce delicate compounds like THC, CBD, and terpenes (think myrcene and limonene) that give them their unique smells and effects. But once the buds are harvested, these compounds start breaking down. They’re sensitive to light (especially UV rays), oxygen, humidity changes, and temperature shifts.

To keep your cannabis fresh, it needs to be stored in a stable environment—around 60–70°F with 58–62% humidity. If it’s too dry, the trichomes can crumble; if it’s too moist, mold can grow. Without proper storage, THC can turn into less potent CBN, terpenes can lose their aroma, and you might end up with a harsh, grassy taste. Even a little light exposure can destroy up to 30% of cannabinoids in just a few weeks, and without enough oxygen, buds can over-cure and turn into dry, flavorless leftovers.

That’s where our durable, airtight glass flower jars come in—they’re designed to protect your cannabis and keep it fresh for longer.

At Apackaging, we’re all about creating custom cannabis packaging that fits your specific needs. With our skills in design, production, and quality control, we make sure your packaging not only matches your brand but also stands out in a crowded market.

Choosing the Design Elements for Your Storage Jars

Turn your packaging into something truly special with our wide range of design options. Whether it’s a smooth, elegant finish or bold, eye-catching digital prints, we take simple storage jars and turn them into standout brand pieces. Add clear windows to give a peek inside or magnifying lens caps—every little detail is designed to make your product shine and grab attention.

Color Coating

Jars are coated with bright, long-lasting colors for a smooth, polished look that boosts your brand’s vibe.

Frosting

A matte, frosted effect created by sandblasting or acid etching. It adds a bit of opacity and some UV protection.

Electroplating

A thin layer of metal (like gold or silver) is added to the jars, giving them a fancy, shiny look that really catches the eye.

Silkscreen Printing

A classic method where ink is pressed through a mesh screen onto the jar. Great for logos or simple designs with fewer than four colors.

Digital Printing

A modern technique that prints high-quality, vibrant designs directly onto the jar using digital files. Perfect for detailed, colorful graphics.

Sticker Labeling

An affordable option where adhesive labels are stuck onto the jars. It’s flexible, easy to design, and quick to produce.

Quality Control for Cannabis Storage Jars

Quality control tests for cannabis storage jars are super important to make sure the product stays safe, effective, and meets all the rules. These tests check things like how strong the jar is, if the materials are safe, how well it blocks UV light, if it’s child-resistant, how it controls humidity, and how durable it is. By putting jars through these tests, manufacturers can guarantee they’re meeting the highest standards to keep cannabis fresh and protect consumers.

Thermal Shock Resistance
Thermal Shock Resistance Test: This test checks how well a glass jar can handle sudden temperature changes without cracking or breaking. Testers put the jars through quick shifts between extreme hot and cold conditions—like heating them up and then dunking them in cold water. The number of times a jar can go through this without failing shows how tough it is. This is super important for cannabis packaging, which might face different temperatures during shipping or storage. High thermal shock resistance means the jar stays intact and the product stays safe, no matter the environment.
Humidity Control Assessment
Humidity Control Test: This test makes sure the jar can keep the right humidity level (usually between 58-62%) for storing cannabis. Testers put humidity sensors inside sealed jars with cannabis or a similar product, then expose the jars to different humidity conditions over time. They also simulate real-world use by opening and closing the jars repeatedly. The goal is to make sure the jar keeps the perfect moisture level, preventing mold from too much humidity or damage to the cannabis from being too dry.
Light Transmission Test
UV Protection Test: This test checks how well glass jars, especially amber or cobalt ones, block harmful UV rays that can break down cannabinoids and terpenes. Testers use special tools to measure how much UV light gets through the glass, focusing on the UVA and UVB ranges. Some tests also look at visible light, since certain wavelengths can still affect cannabis quality. The results help manufacturers tweak their glass formulas and tints to give the best protection, keeping the cannabis potent and fresh for longer.
Internal Pressure Strength Test
Pressure Resistance Test: This test checks how much pressure a glass container can handle before it breaks. Jars are sealed and slowly pressurized until they burst, and the pressure at which they fail is recorded. This helps manufacturers figure out how safe the jars are for different uses, especially for products that might build up pressure over time.
Airtight Seal Verification
Oxygen Barrier Test: This test makes sure cannabis storage jars keep oxygen out, since exposure can ruin the product. Testers use special equipment to measure how much air gets in and out of the jar. The goal is to confirm that the jar’s seal—often made with silicone or rubber—can keep the air out and maintain the perfect environment for storing cannabis.
Child-Resistant Closure Verification
Child-Resistance Test: This test makes sure cannabis packaging is safe for kids but still easy for adults to open. It follows strict rules from the Poison Prevention Packaging Act and has two parts. First, a group of kids aged 42-51 months tries to open the package within a set time. Then, adults aged 50-70 test how easy it is to open. To pass, the package has to stop most kids from opening it while letting most adults open it easily. This is a must for meeting safety rules and keeping consumers safe in the cannabis industry.
Chemical Inertness Evaluation
This test makes sure that glass jars used for storing cannabis don’t react with the product or release harmful chemicals over time. Testers expose the glass to different solvents or simulated cannabis products, often at high temperatures to speed up any potential reactions. Afterward, they check the liquid for any traces of substances that might have leaked from the glass, like heavy metals or alkali compounds. They also look at the glass surface for signs of wear or damage. The goal is to confirm that the glass stays stable and doesn’t react, keeping the cannabis pure and potent for as long as possible.

FAQ

Most frequent questions and answers regarding cannabis storage jars
How long does cannabis stay fresh in a good storage jar?

If you store it right—in an airtight glass jar, away from light and heat—your cannabis can stay fresh for 6 months to a year. With humidity control packs and perfect conditions, some say it can last up to 18 months.

Fill it about ¾ full. This leaves enough air for curing and prevents mold, but not so much that it speeds up degradation. As you use your stash, move it to smaller jars to keep the fill level just right.

For freshly cured cannabis, burp the jars once a day for the first week, then once a week for the next month. This lets out extra moisture and brings in fresh air. If you’re using humidity packs for long-term storage, you don’t need to burp.

Wash them with hot water and unscented dish soap, rinse well, and let them dry completely. For a deeper clean, use isopropyl alcohol to get rid of any leftover resin. Make sure the jar is totally dry before storing cannabis to avoid mold.

What’s the best environment for storing cannabis jars?

Keep them in a cool, dark, and dry spot. The ideal temperature is 60–70°F (15–21°C) with 58–62% humidity. Avoid heat and sunlight to keep your cannabis potent and flavorful.

Yes! UV light can break down cannabinoids and terpenes, messing with potency and flavor. Amber or cobalt blue glass jars block UV light and help keep your cannabis fresh longer.

It’s better to keep strains separate. Mixing them can mess up their unique flavors and smells. Plus, it helps you stay organized and avoids cross-contamination if one strain has issues like mold.

Not really. While they’re okay for short-term storage, the lack of oxygen can damage trichomes and flatten buds. For long-term storage, regular airtight jars with humidity control are the way to go—they keep your cannabis fresh and intact.
