Custom Plastic Clamshell Packaging

FormTight designs and manufactures custom plastic clamshell packaging for brands requiring durable protection during shipping and retail display. With in-house design, tooling, and thermoforming, we move from concept to production quickly, delivering consistent, high-quality packaging solutions.

Clamshell packaging is a hinged plastic container that opens like a shell and secures products between two formed halves. These packages combine product protection with retail visibility, featuring a living hinge that connects the front and back sections for easy opening and reclosing.

Unlike traditional packaging that requires separate components, clamshells provide an all-in-one solution that protects against damage, deters theft, and displays products attractively.

Materials

• PET: Crystal-clear visibility with excellent impact resistance; ideal for retail display where product visibility drives sales.
• Recycled Content: Post-consumer and post-industrial options available for sustainability initiatives
• PVC: Superior sealing properties for hermetic closures; recommended when edge-sealing or RF welding is required

Closure Systems

• Perimeter Snaps: Full-edge engagement for secure closure and easy reopening
• Button Snaps: Strategic snap points that balance security with user-friendly access
• Heat Sealing: Permanent closure for tamper-evidence and product security
• Custom Mechanisms: Customized closure designs for unique brand experiences or specific security needs

Display Formats

• Bi-fold Design: Classic clamshell with single hinge for straightforward packaging
• Tri-fold Design: Multiple panels for larger products or multi-component sets
• Quadfold Design: Integrated foot design for shelf stability and improved merchandising
• Hanging Features: Die-cut holes, j-hooks, or delta punches for pegboard display systems

We engineer packaging solutions tailored to the demands of different industries, balancing protection, visibility, and usability.

Retail & Consumer Products

Clear, attractive packaging that prevents theft while allowing product inspection. Our retail clamshells feature smooth edges for safe handling and graphics-ready surfaces for labels or inserts.

Medical & Healthcare

Durable enclosures for non-sterile medical devices, diagnostic components, and healthcare accessories. 

Industrial & Hardware

Heavy-duty clamshells that organize and protect tools, fasteners, and components. Reinforced corners and thicker gauges accommodate heavier items while maintaining stackability for efficient storage.
