Pre-Roll Jars FAQ
What joint lengths and cone counts fit pre-roll jars?
Pre-roll jars accommodate single 70mm dogwalkers up to 5-pack 84mm 1 1/4 size pre-rolls and 100ml multi-joint arrangements. Formed across thick-wall flint glass, UV-blocking violet glass, matte coated glass, and shatterproof PET plastic, these cylindrical containers maintain interior headroom clearance so joint tips do not crush against the cap liner during sealing.
- eBottles 33mm Mini & 38mm PET Bottles: Sized for single 70mm dogwalkers or slim 84mm joints standing upright.
- Grand Puff & eBottles 84mm Glass Jars: Formatted for multi-packs holding up to five 84mm 1 1/4 size pre-roll cones.
- Grand Puff 100ml Violet & 6oz Matte Black Jars: Fits up to 10 full-gram 98mm or 109mm king-size pre-rolls or 7g bulk flower.
- eBottles 60 Dram PET Jars: Straight-sided 53/400 neck profile accepts multi-joint arrangements or 7g dry herb charges.
Are glass and plastic pre-roll jars child resistant without caps?
Glass and PET jar bodies alone are non-CR shells and require pairing with a certified push-down-and-turn closure to achieve 16 CFR 1700.20 compliance. Threading a certified child-resistant cap onto the continuous-thread finish completes the two-piece CR packaging system. Downward vertical pressure engages the outer cap drive teeth with the inner threaded collar, allowing counter-clockwise unthreading under Title 16 CFR 1700.20 and ASTM D3475 standards, while free-spinning ratchet mechanics stop unauthorized child opening.
To cross-reference state retail packaging mandates, review our State Compliance Regulations Guide or verify jar neck finishes using our Flower Jar Sizing Chart.
How do violet glass and matte coatings stop terpene off-gassing?
Dark violet glass and opaque matte black coatings filter visible light wavelengths between 400nm and 700nm, stopping photo-oxidation of delicate monoterpenes and cannabinoids. Combining light-blocking glass walls with polycone or foam-backed continuous-thread caps seals volatile aromatic compounds inside the jar headroom. This hermetic closure stops moisture loss, maintaining joint paper moisture balance and burning characteristics during extended retail display.
What label stock bonds to cylindrical glass and PET pre-roll bottles?
Flexible pressure-sensitive BOPP synthetic labels with aggressive permanent acrylic adhesives prevent edge-flagging on small-radius 33mm and 38mm bottle walls. Non-porous glass and PET surfaces allow high-tack adhesives to form immediate bonds without bubbling or lifting during cold-room storage.
Processing facilities can streamline packaging lines by utilizing our In-House Label Application Service Page to apply variable strain data and compliance labels with machine accuracy prior to filling.
How do corrugated cell dividers prevent glass jar breakage in transit?
Master shipping cases utilize die-cut corrugated cell partitions that isolate each glass jar, preventing glass-on-glass impact during palletized freight transit. Lightweight PET plastic bottles eliminate shatter risks entirely on automated filling lines while reducing gross tare weight to lower LTL freight shipping costs.
