Custom Clamshell Blister Packs | 360-Degree Clear Retail Packaging

Clamshell blister packs use a single piece of thermoformed transparent plastic — folded at a central hinge — to completely enclose the product on all sides in clear plastic. Unlike face seal blisters that attach to a paperboard card, clamshells are self-contained all-plastic enclosures that maximize product visibility, provide exceptional theft deterrence, and can be resealed or snapped shut after opening.

Construction

Clamshells are thermoformed from a single PVC or PET sheet with a living hinge at the fold point. The two halves close over the product and are secured with heat sealing, sonic welding, or press-fit snap tabs. Branding is communicated through printed insert cards visible through the clear plastic, in-mold labels, or applied labels.

Security Features

Clamshell packaging is among the most effective anti-theft retail formats — the rigid all-plastic enclosure is extremely difficult to open quietly or conceal after opening, making clamshells the preferred format for high-theft retail categories including consumer electronics, razors, and batteries.

Clamshell Security in High-Theft Retail

Clamshell packaging is the retail security standard for high-theft product categories — consumer electronics, razors, batteries, and small tools in open-format retail environments. The rigid all-plastic enclosure is extremely difficult to open without tools, cannot be resealed convincingly after tampering, and makes concealment physically awkward. Major mass retailers specify clamshell packaging for shrink-sensitive categories precisely because its security characteristics meaningfully reduce retail theft.

Closure Systems for Custom Clamshell Packs

Clamshell closure systems range in security and cost. Press-fit snap tabs are the most economical — the clamshell snaps shut and can be resealed. Heat sealing fuses the edges permanently after filling — the strongest tamper-evident closure. Sonic welding uses ultrasonic vibration to bond plastic edges cleanly without heat — producing the neatest sealed edge for premium retail presentation.

Branding Custom Clamshell Packaging

All-plastic clamshell packs use printed insert cards placed inside the clamshell — visible through the clear plastic, providing full brand communication without external labels. Insert cards allow brand updates without modifying clamshell tooling. In-mold labels and applied pressure-sensitive labels are alternatives for different branding requirements.

Clamshell Blister Packs in California — FAQs

What is a custom clamshell blister pack?

A clamshell blister pack is a thermoformed package from a single clear plastic sheet with a living hinge at the fold point — the two halves fold together to completely enclose the product in transparent plastic on all sides. Unlike face seal blisters, clamshells require no paperboard backing card and are self-contained all-plastic packaging.

What closure options are available for custom clamshells?

Three main closure systems: snap-close press-fit tabs (resealable, most economical), heat seal (permanently fused edges, maximum tamper evidence), and sonic weld (ultrasonic bonding, cleanest edge for premium retail). Selection depends on security requirements and production equipment.

How is branding applied to custom clamshell packs?

The most common method is a printed insert card placed inside the clamshell — visible through clear plastic, providing full brand communication without external labels. Insert cards can be changed without modifying clamshell tooling. Applied labels and in-mold labels are alternatives.

Are custom clamshell packs suitable for pharmaceutical products?

Yes. Child-resistant clamshell configurations use push-through foil backing on individual product cavities, certified to CPSC 16 CFR 1700.20. Standard non-CR clamshells are used for OTC products not requiring child resistance.

What is the minimum order for custom clamshell blister packs?

Our minimum order is 100 units. Custom thermoforming tooling is produced in 10–14 business days and retained for repeat orders at no additional charge.

Do you offer sustainable packaging options for California brands?

Yes. We offer FSC-certified paperboard, recycled content corrugated, soy-based inks, and compostable coating options. California brands with sustainability mandates or eco-conscious positioning can build a fully sustainable packaging program with My Custom Boxes.

Can LA beauty brands get luxury custom boxes with small quantities?

Absolutely. Our 100-unit minimum combined with rigid box options, soft-touch lamination, foil stamping, and embossing makes premium beauty packaging accessible for LA beauty brands at any stage of growth.

Do you produce cannabis packaging that meets California regulations?

Yes. Our California cannabis packaging meets CDPH requirements including child-resistant options, opaque packaging requirements, and compliant label panel sizing. We stay current with California's evolving cannabis packaging regulations.

How long does it take to get custom boxes shipped to California?

Production takes 10–14 business days from proof approval. Shipping within California typically takes 2–3 business days. Rush production is available at a 15% surcharge for time-sensitive launches.

Do you serve California's agricultural and food processing industry?
