Learn More About Concentrate Glass Jar

Why are glass jars the preferred choice for storing cannabis concentrates?
Glass jars are widely favored because they are chemically inert (don’t react with the concentrate), non-porous, and can create an airtight seal. This helps preserve the potency, flavor, and freshness of the concentrate by protecting it from air, light, moisture, and potential degradation.
Do I need jars with UV protection?
UV-protected jars, such as those made of opaque glass, are highly recommended, although not strictly essential. UV light can degrade cannabinoids and terpenes, reducing potency and altering the flavor profile. Clear glass jars should be stored in a cool, dark place away from direct sunlight or bright artificial lights.
What are the common sizes for concentrate glass jars?
5mL: Designed for 1 gram of concentrate.
7mL: Designed for 1 gram to 1.75 grams (half an eighth) of concentrate.
15mL: Can fit between 3.5 grams and 7 grams of cannabis extract.
3oz: A popular choice for larger amounts, accommodating 28 grams of concentrate.
Can I customize my concentrate glass jars?
You can customize jars with a brand’s logo, colors, and designs using various techniques like direct printing, labels, color coatings, or custom closures.
