Smell Proof Jar Styles
Six jar formats — from the classic dispensary flower jar to the tech-forward humidity-display model that tells customers exactly how well you've preserved their product.
CR Matte Black Glass Jar
Opaque matte black glass with a child-resistant push-and-turn lid. Blocks 100% of light — no UV, no visible spectrum — which is what actually degrades cannabinoids and terpenes on a dispensary shelf under fluorescent lighting. The silicone gasket inside the lid compresses to a hermetic seal when closed. This is the jar that makes flower look like it was worth the price before the customer opens it.
Smart Jar with Humidity & Temp Display
A digital hygrometer and thermometer built into the lid face, visible through a small display window. The customer doesn't just trust that the flower is fresh — they can read the exact relative humidity and temperature inside the jar at any moment. For premium flower brands, this is the one feature that no competitor explanation can replicate. Ideal humidity for cannabis is 55–65% RH; this jar shows exactly where yours sits.
Custom Color CR Jar
Opaque glass in any Pantone-matched color — pink, white, sage green, cobalt, or matched exactly to your brand palette. The color is in the glass itself, not a coating, so it won't chip or fade after a few months on shelf. CR push-and-turn lid in a matching or contrasting color. For brands building a product line where each strain has its own color, this jar makes the visual system work without relying on labels to carry all the differentiation.
Square Glass Jar
Rectangular profile in clear or tinted glass with a matte black lid. The square footprint stores 20–30% more efficiently than round jars on a display shelf — dispensaries notice this when stocking. Four flat label faces instead of one curved surface means more room for strain information, terpene profiles, and compliance text without the awkward curve that makes label application inconsistent at scale. Available 1oz to 8oz.
Amber UV-Blocking Glass Jar
The pharmaceutical standard for light-sensitive contents — applied to cannabis. Amber borosilicate glass absorbs UV wavelengths below 450nm, which are the ones that break down THC into CBN and degrade terpene profiles. The contents are still visible through the warm amber tint, so customers can inspect bud quality before buying. Black lid, hermetic gasket seal. The jar that signals science-backed preservation without any text.
Clear CR Glass Jar
Crystal-clear borosilicate glass with a CR push-and-turn lid. The product is the display. For indoor-grown flower with exceptional bag appeal — vivid green, dense trichome coverage, visible structure — this is the jar that lets the flower sell itself. The airtight silicone-gasketed lid keeps the aroma locked inside until the customer opens it. When used with a custom label, the visible bud behind the label creates a layered presentation no opaque jar can match.
What "Smell Proof" Actually Means — and What It Takes to Deliver It
A lot of jars claim to be smell proof. Four engineering decisions separate the ones that actually are.
The Seal Is a Silicone Gasket, Not a Thread Gap
Odor escapes through the path of least resistance. On most threaded lids, that's the thread gap between lid and body — a spiral of micro-openings that terpene vapor navigates with ease. Our lids use a compressed silicone gasket that sits against the jar rim and forms a hermetic seal under light hand pressure. When closed, the gap is eliminated entirely. Terpene vapor has no exit. That's what makes it actually smell proof, not just smell reduced.
UV-Blocking Glass Preserves Potency on the Shelf
Dispensary lighting — typically fluorescent or LED — emits UV and visible-spectrum radiation that degrades THC into CBN and oxidizes terpenes over weeks and months. Amber glass absorbs the damaging wavelengths below 450nm. Opaque black glass blocks everything. A jar sitting in a well-lit display case for six weeks is a meaningful amount of product degradation if the glass doesn't filter the light. We offer clear, amber, and fully opaque options — and we'll tell you which one your shelf environment actually needs.
CR Lid Certified by a Third-Party Lab, Not Us
The push-and-turn mechanism on our lids requires simultaneous downward pressure and rotation to open — calibrated to resist the hand strength and coordination of a child under five while remaining easy for adults. That's not our description of it; that's what ASTM D3475 testing actually measures, performed by an independent laboratory. Certification documentation ships with every order. You have what you need for any state compliance audit before the product hits the floor.
Custom Label, Lid Color & Outer Box — One Order
Screen print your logo directly on the glass, or apply a custom-cut pressure-sensitive label with strain name, terpene profile, batch number, and a QR code linking to your COA. Match the lid color to the jar or go contrasting. Add an FSC-certified outer carton with your full brand design and compliance text. All three from the same factory, same shipment — no vendor coordination, no mismatched lead times arriving separately at your facility.
Why Cannabis Brands Order Their Smell Proof Jars from Hemployd
Ten years of making these jars. We know what fails at six months on a lit dispensary shelf — and we've engineered those failure points out of what we ship.
CR Docs with Every Shipment
ASTM D3475 certification documentation ships standard with every CR lid order — not by request, not for a fee. You have it before the first state audit, not after it starts.
4 Glass Types, All UV-Tested
Clear, amber, opaque black, and custom color — each glass type is tested for UV transmission so we can tell you exactly what wavelengths each option blocks. You choose based on your shelf environment, not guesswork.
Jar + Label + Box, One Factory
Glass jar, custom label, and FSC-certified outer carton from the same production facility. One lead time. One shipment. No coordination between three separate vendors who don't know each other's schedules.
DDP to US & Canada
Export, customs duties, and last-mile delivery handled. ASTM and FSC documentation inside the shipment. You sign for the pallet and start filling. No customs broker coordination, no import fees outside the quoted price.

Four brands. Four different reasons the jar made a difference.
"Our flower stayed green and fragrant for 90 days on shelf."
We were seeing visible color loss and aroma fading at the 30-day mark with our previous clear jars under LED lighting. Switched to Hemployd's amber UV-blocking jars. Shelf-life testing at 90 days showed no measurable terpene loss and the flower color stayed consistent. Our dispensary partners started commenting on quality before we told them we changed the packaging.
— J.M., Product Director · Denver, CO
"The hygrometer jar raised our dispensary sell-through rate noticeably."
We started using the humidity display jar for our indoor top-shelf line. Budtenders started showing customers the humidity readout — "it's at 59% RH right now, exactly where it should be." That kind of verifiable freshness claim changes the conversation at the counter. Our sell-through on that line improved measurably the first quarter after the switch.
— A.K., Brand Founder · Grand Rapids, MI
"Square jars cut our dispensary stocking time in half."
We supply 40+ dispensaries and one of the constant complaints was about fitting round jars in display cases efficiently. Switched five of our brands to Hemployd's square jar. The dispensaries can fit 30% more units per shelf foot, stocking is faster, and the four-face label area is better for compliance text. Three of those brands increased their display allocation as a direct result.
— T.R., Operations Director · Los Angeles, CA
"ASTM docs and jar arrived together — cleared Health Canada in one review."
We needed CR documentation for our flower jars as part of the Health Canada packaging review. Hemployd had the ASTM D3475 report included in the shipment documentation before we even asked for it. The review cleared in a single submission. DDP to Vancouver meant the pallet landed on exactly the day quoted — which matters when you have a production schedule to hit.
