5ml UV Resistant Heavy Bottom Jar with Child Resistant Black Lids

The 5ml UV Resistant Heavy Bottom Jar with Child Resistant Black Lid is a professional-grade glass concentrate container designed for extractors, processors, and cannabis brands packaging premium products. The UV-blocking glass shields light-sensitive extracts from degradation, while the thick weighted base delivers a luxury feel that matches top-shelf positioning. At 5ml capacity, it's sized for single gram fills, samples, and retail offerings where terp preservation actually matters.

Key benefits

• Terps and potency stay locked in — UV-resistant glass blocks the light wavelengths that break down cannabinoids and aromatics over weeks on the shelf.
• Weighted base that doesn't tip — The heavy bottom keeps jars planted during filling sessions, display setups, and photography shoots.
• CR lids that actually work — Press-and-turn child-resistant mechanism meets compliance expectations without making adults fight with every jar.
• Right-sized for 1g portions — 5ml fits most half-gram to full-gram fills with minimal headspace, so your product looks full without being crammed.
• Smooth interior walls — No seams or ridges to trap product, which means cleaner fills and better recovery when customers scrape out every last bit.
• Uniform sizing for production lines — Stacks neatly in boxes, labels consistently, and photographs well in rows for menus and dispensary displays.

Made for

Licensed extractors and processors packaging live resin, hash rosin, badder, diamonds, and other premium concentrates. Brands stepping up from generic plastic to something that matches their product quality. Labs running small batches where presentation matters as much as protection. If you're already using heavy-bottom glass in your glass jar lineup, these slot right in without disrupting your aesthetic.

How to use it

These jars work as your primary container for solventless rosin, BHO, live resin, and any concentrate where you want to preserve color and aroma through the supply chain. The UV protection is especially valuable for products sitting in dispensary cases under lights all day.

For filling, set up a row of jars on a nonstick dab mat to catch any overflow. Remove the CR lids, dose your concentrates directly into the glass, then press and twist the lids back on. The heavy base keeps everything stable while you work through a batch. Label with strain info, batch numbers, and compliance data once sealed.

Most labs press or cure their material on parchment paper first, then portion directly into jars for final packaging. The 5ml size lets you maintain consistent SKUs across strains—just swap the label. For additional light protection during transport or storage, some brands double up by placing filled jars inside mylar bags for redundant UV blocking.

Specifications

Fit and compatibility

The 5ml format hits the sweet spot for gram and half-gram fills. Big enough to show off your product, compact enough for efficient storage and shipping. If you're running a production line, standardizing on this size means your team isn't juggling a dozen container formats every shift. The straight walls accept most standard label sizes, and the uniform height makes them easy to box up in branded secondary packaging.

These aren't meant for flower or pre-rolls—for those, check out joint tubes or larger containers in the storage lineup.

Care and cleaning

Let any leftover concentrate cool, then wipe out the interior. For deeper cleaning between batches, soak the glass in isopropyl alcohol, rinse with warm water, and let it dry completely before refilling. Keep solvents away from the lid's printed surfaces and any interior liners to preserve their integrity.

FAQ

• What concentrates work best in these jars?

  Pretty much anything: rosin, live resin, hash rosin, crumble, badder, diamonds with sauce, and similar extracts. The UV-resistant glass is especially useful for premium SKUs where you're trying to preserve color and terp profile over weeks of shelf time. For more information on concentrate storage best practices, Leafly's concentrate guide covers the basics of what degrades extracts over time.

• Are these lids actually child resistant?

  Yes. The black lids use a standard press-and-turn CR mechanism that's significantly harder for kids to open while still being manageable for adults. That said, always store cannabis products securely and out of reach of children regardless of packaging type.

• How much does the UV protection actually help?

  Light exposure—especially UV wavelengths—accelerates the breakdown of THC into CBN and degrades terpenes that give concentrates their flavor and aroma. The UV-blocking glass reduces this exposure significantly compared to clear glass. Combined with the tight-sealing CR lid limiting air exchange, you're giving your product a better chance at maintaining quality through the supply chain.

• Will a full gram of concentrate fit?

  Yes. 5ml is the industry standard size for 1g fills across most concentrate textures. You'll have enough room for clean presentation and easy scooping without excessive headspace that makes the jar look underfilled. If you're packaging 2g or larger portions, step up to a bigger format in the concentrate jars collection.

• Can I label these easily?

  Definitely. The straight walls and uniform dimensions accept standard wraparound labels cleanly. Most brands also add tamper bands between the lid and jar for additional security. The dark glass and heavy bottom read as premium without needing fancy secondary packaging, though they box up nicely if you're going that route.

• How do I clean these for reuse?

  Scrape or wipe out as much product as possible once it cools. Soak the glass in isopropyl alcohol for stubborn residue, rinse thoroughly with warm water, and let everything air dry completely. Don't trap moisture in there with fresh product—that's asking for mold issues.

• What bulk quantities are available?

  Cases come in 80, 160, or 320 jars so you can scale with your production volume. Whether you're running test batches or full commercial operations, there's a case size that makes sense. The price per jar drops as quantity increases, which is standard for packaging supplies.
