Clamshell Packaging Formats
One hinge, endless formats. Choose the clamshell structure that fits your product and your market.
Hinged Plastic Clamshell
The workhorse of the clamshell world. Clear PET body snaps shut with a satisfying click — child-resistant latch included. Fits pre-rolls, cartridges, and small accessories.
Blister Clamshell
Thermoformed clear bubble bonded to a printed cardboard backer. Gives your product the retail pharmacy look that signals quality — perfect for single-dose edibles or capsules.
Paperboard Clamshell Box
FSC-certified paperboard scored and folded into a rigid hinged box. Premium matte or soft-touch finish on the outside, clean uncoated stock inside. High-end unboxing experience.
Multi-Pack Pre-Roll Clamshell
Designed to hold 3, 5, or 10 pre-rolls in individual formed slots. Each unit stays exactly where placed. The CR snap-lock keeps the pack compliant while the clear window sells.
Vape Cartridge Clamshell
Slim-profile clamshell precision-molded to hold 510-thread and proprietary cartridges securely. The cartridge floats in a formed cavity — no rattling, no scratches.
Luxury Rigid Clamshell
Thick-walled rigid board wrapped in art paper, with a magnetic or ribbon-pull closure. Designed for premium gifting SKUs and dispensary top-shelf placement.
Built for Clamshell — Not Adapted From It
Every feature below exists because clamshell packaging has its own engineering demands. We've spent 15 years getting those details right.
The Hinge IS the Safety Feature
Most clamshells treat child-resistance as an add-on. Ours builds it into the hinge geometry itself. The CR latch requires simultaneous squeeze-and-lift — tested and certified to ASTM D3475 and PPPA.
Customers Buy What They Can See
A clear PET panel lets the product sell itself at the shelf. For flower, concentrates, and pre-rolls, visibility drives conversion. We offer full-clear, window-panel, and frosted options.
Tamper-Evident Seal — No Guesswork
A perforated breakaway tab wraps the hinge before first open. Once torn, it can't be faked. Every dispensary customer and regulator can confirm at a glance that the package hasn't been touched.
Full-Color Print on Every Surface
The card insert, the thermoformed shell, and the outer box — all printable. Pantone-matched ink, CMYK offset, UV spot, foil stamping, soft-touch lamination. 3D digital mockup within 24 hours.

What Dispensaries Say
Real feedback from the buyers, compliance officers, and brand founders who reordered.
"Cleared the CR audit without a single revision."
We switched to Hemployd's clamshells for our pre-roll multi-packs because we kept failing state inspections with our old supplier. The ASTM D3475 documentation came with the first shipment and the audit went through clean. We haven't looked back.
J.M., Procurement Manager
"The clear window is what our customers actually buy."
We push product into 40+ dispensaries in SoCal. The clamshell's visibility window doubled our sell-through on premium flower SKUs compared to the opaque containers we used before. Budtenders love showing it to customers.
