Vape Cartridge Packaging: Carts, Boxes and Inserts

Define the retail unit before you draw a box

Vape cartridge packaging has three jobs that are easy to blur: hold the cartridge, present the product and carry required information. Start by naming the retail unit your customer buys and the package your state cannabis regulator treats as the unit that must meet packaging rules. A cartridge can be the immediate package while a box is secondary packaging. For PPPA-regulated substances, CPSC guidance says special packaging must be primary or immediate packaging; special packaging only at the secondary level would not comply with the PPPA. That guidance does not establish which package a state cannabis rule requires to be child-resistant. Do not assume either that a child-resistant box is sufficient or that cartridge-level child resistance is always required. Confirm the applicable rules and regulated package with counsel or your state regulator before artwork is released.

Write a cartridge-first packaging brief

Write a cartridge-first packaging brief that separates measured facts from assumptions. The brief should travel with the artwork, insert drawing and sample request so every supplier works from the same inputs. Include the following.

• Product drawing with nominal dimensions and tolerances for length, diameter, mouthpiece, base and any raised features.
• Cartridge materials, including glass, plastic, metal threads and finish, because contact and stress points affect insert design.
• Fill state and orientation: empty, filled, capped, labeled or bundled, and whether the cartridge can leak or rotate in transit.
• Label dimensions, required copy, batch or variable data and the area that must remain visible.
• Retail unit, units per box, box orientation and whether the box is the shelf package or a shipping outer.
• State or channel packaging questions that need a legal or regulatory answer, kept separate from design preferences.
• Artwork status, dieline source and the converter's proof and layer instructions.
• Sample cartridges or a dimensionally representative model for fit checks.
• For a Teal quote, send this brief with a sample. Teal's standard MOQ is 50 units, specialty rigid is 100, and Teal does not charge setup, plate or tooling fees. Ask Teal about sample options when you request a quote.

Fit the insert as a retention system, not a filler

An insert is a retention system. It should stop the cartridge from moving, protect the mouthpiece and base, and let the customer remove the product without fighting the package. Clearance is a design choice, not a universal number. Too little clearance can crack glass, scratch a finish or make removal difficult. Too much clearance lets the cartridge rattle and can damage a label. Test insertion and removal with the actual cartridge, not a generic cylinder.

Use a simplified geometry model to set starting clearances, then validate with physical samples. Do not treat a flat insert panel as if its dimensions equal the product dimensions. A channel needs length, width, depth, lead-in and a stop. If the cartridge has a wider mouthpiece or base, the channel may need a stepped profile or a relief. Keep retention away from fragile joints and avoid placing force on the mouthpiece. Paperboard, molded pulp, thermoformed plastic and foam can all work, but each has different draft, tolerance and removal feel. Ask for a sample before committing to a production run.

Choose the box format around the retail unit and channel

Choose the box format around the retail unit, the channel and the insert. The table is a planning aid, not a compliance determination.

Run a child-resistant review workflow

Child-resistant packaging is a performance claim, not a box style. CPSC's special packaging FAQs describe child-resistant testing thresholds: at least 85 percent of tested children must not open the package during the first 5 minutes, and at least 80 percent must not open it during the full 10 minutes. For adult-friendly use, at least 90 percent of adults must open the package within 5 minutes and, if applicable, properly resecure a second package within 1 minute. These are testing protocol facts, not a statement that every vape package must meet them.

CPSC does not approve, certify or endorse specific packages, manufacturers or testing firms. For PPPA-regulated products, the finished product manufacturer is responsible for selecting suitable packaging and generating a General Certificate of Conformity when required. Build a review workflow: ask counsel or your regulator which rules apply, which package they cover and which test protocol and certification records are needed. ASTM D3475 package types and the CPSC Special Packaging Index can serve as reference points, not proof of compliance. The index is not comprehensive, and CPSC staff has not verified the manufacturers' test data. Obtain applicable test reports from a qualified firm and keep them with the product file. Do not describe a package as child-resistant until the responsible manufacturer has validated it under the applicable protocol.

Coordinate artwork, labels and proofs with the converter

Artwork has to fit the physical package and the converter's workflow. Put variable data, batch codes, state symbols, warnings, QR codes and required copy into the brief before the dieline is final. Ask the converter how registration black and rich black should be handled, which spot colors are named, and whether the workflow uses plates or digital simulation. PDF/X-4 can carry color-managed RGB, so do not reject an RGB file by rule; agree the color workflow with the printer and convert as requested.

Printer marks, dieline visibility, layer naming and proof type should follow the converter's instructions, not a generic checklist. Request a proof that shows the dieline, fold lines, glue areas and label safe zones. Check that the proof uses the correct cartridge orientation and that no required copy falls on a fold or under an insert rail. Keep a signed proof with the packaging file.

Worked geometry example: three-channel insert

Suppose a hypothetical cartridge is 10.8 mm in diameter and 62.0 mm overall length. You plan a horizontal three-channel paperboard insert. Use a channel width of 12.0 mm, which is 10.8 mm plus 1.2 mm total width clearance. Use a channel length of 64.0 mm, which is 62.0 mm plus 2.0 mm total end clearance. Use two rails of 3.0 mm between channels. Across the three channels, the insert width is 3 times 12.0 mm plus 2 times 3.0 mm, which equals 42.0 mm. Add a 2.0 mm margin on each side: 42.0 mm plus 4.0 mm equals 46.0 mm. If you also add a hypothetical 2.0 mm margin at each end, the insert length is 64.0 mm plus 4.0 mm, which equals 68.0 mm. The hypothetical footprint is therefore 46.0 mm by 68.0 mm. Channel depth, board caliper, lead-in and stops are not included. This is a simplified geometry exercise, not a manufacturable dieline. Validate retention, removal and cartridge stress with physical samples.

Use a pre-production checklist

Use this pre-production checklist before you approve a box and insert.

• Cartridge drawing and tolerances match the sample used for fit.
• Retail unit and regulated package are named in writing.
• Child-resistant applicability question is answered by counsel or regulator.
• Insert channels have length, width, depth, lead-in and stop defined.
• Insert holds the cartridge without loading the mouthpiece or fragile joint.
• Removal force is checked by more than one person and with filled units.
• Box internal dimensions are checked against the insert, not only the cartridge.
• Artwork, dieline, layers and proof follow the converter's instructions.
• Variable data and required copy are proofed on the final shape.
• Physical samples pass fit, label and handling checks before production.

Know the scope limits

This guide is an editorial planning framework, not legal advice, a state-by-state compliance matrix or a child-resistant certification. It does not determine whether a cannabis vape product requires special packaging, does not set a safety threshold and does not replace compatibility, stability, leak or transit testing. CPSC sources cover special packaging principles and testing protocol facts; they do not approve Teal products or any package. Confirm channel, state and carrier requirements in your own agreements and with qualified professionals. For fit work, treat geometry as an estimate until samples pass.
