Form factors at a glance

“Packman-style” disposables are single-flavor AIO housings tuned for predictable draw and simple retail UX. Postless and dual-chamber variants add routing changes or a second reservoir to unlock flavor flexibility, at the cost of tighter tolerances and extra QC. Browse the family at packman vape.

Flavor flexibility: when two chambers win

Dual-flavor menus & pilots

Dual-chamber designs let you ship two SKUs in one shell—ideal for seasonal drops, collabs, and retail demos. Electronic switch units should debounce toggles and confirm the active chamber via LEDs/display to avoid mis-fires and customer confusion.

Mix-and-match vs. consistency

While switchable devices broaden choice, single-chamber disposables still lead on simplicity and uniformity for entry SKUs.

Maintenance & RMA risk

Sealing & condensate control

Ask suppliers for assembly drawings and tolerance tables (o-ring durometers, cap compression) and validate with heat-soak/altitude leak tests. Dual-path layouts require separate pressure-drop and output curves for each channel.

Battery & transport documentation

For integrated-cell hardware, keep a UN 38.3 test summary for the exact cell/pack on file; U.S. PHMSA requires manufacturers to make standardized test summaries available for transport compliance. :contentReference[oaicite:2]{index=2}

Align designs and QA with practices referenced in IEC 62133-2—covering portable, sealed secondary lithium systems under intended use and foreseeable misuse—to reduce field failures. :contentReference[oaicite:3]{index=3}

Labeling & symbols: who’s responsible?

Hardware vendors provide shells, documentation, and dielines. Finished-goods labels (warnings/symbols) are the licensee’s duty. Some states are adopting the International Intoxicating Cannabinoid Product Symbol (IICPS) standardized as ASTM D8441 for consumer packages—confirm requirements before print. :contentReference[oaicite:4]{index=4}

Legal frameworks vary by state and change frequently; NCSL tracks medical (40 states + DC) and adult-use (24 states + DC) status as of June 26, 2025—always verify the latest rules where you operate. :contentReference[oaicite:5]{index=5}

Procurement checklist (EMPTY hardware only)

• Specs: capacity & headspace; window geometry; ceramic grade & porosity vs. viscosity; USB-C profile & protections.
• Bench: output curves; pressure-drop vs. flow; heat-soak/altitude leak tests; switch debounce/endurance (dual-chamber).
• Docs: UN 38.3 test summary; QC sheets; (where applicable) RoHS/REACH; dielines for label owners.
• Supply: MOQ, lead time, warranty, lot traceability, and after-sales process.

FAQ

Do you sell filled cannabis products?

No. We only supply empty hardware shells (no oil) for licensed B2B filling in legal jurisdictions.

Who provides cannabinoid COAs?

Your licensed oil supplier and accredited labs. We provide hardware QA/transport documents such as UN 38.3 test summaries. :contentReference[oaicite:6]{index=6}
