Clamshell Packaging

Clamshell packaging fully encloses a product between two connected, hinged halves formed from a single sheet, while blister packaging typically seals a product between a formed plastic cavity and a flat card or foil backing. Clamshells offer full visibility and easier consumer access, while blisters are common for smaller retail items requiring a rigid backing.

Clear PET (polyethylene terephthalate) is a common material for clamshell packaging due to its clarity, strength, and recyclability. Other materials such as PVC or PETG may also be used depending on application requirements, but PET remains widely preferred for food-contact and retail-ready packaging needing strong product visibility.

Yes, clamshell packaging materials used for food applications are typically produced under food safety certifications such as ISO 22000:2018, FSSC 22000, and HACCP compliance. These standards ensure materials meet food-contact safety requirements, making clamshells suitable for fresh produce, meat, and other food and beverage products.

Yes, clamshell packaging can be thermoformed to different sizes, shapes, and cavity configurations depending on product dimensions and retail presentation needs. Custom tooling allows brands to fit specific items such as produce, electronics, or consumer goods while maintaining protective and tamper-resistant qualities.

Minimum order quantities for clamshell packaging vary depending on product type, substrate, and tooling requirements. A product-specific quote is required to determine exact minimums, as no fixed volume threshold applies universally across all clamshell packaging configurations.

Clamshell packaging is commonly sealed using heat sealing, adhesive tabs, or friction-fit hinge closures depending on the design. Some clamshells include tamper-evident features or locking tabs to secure the package during shipping and retail display while maintaining ease of consumer access.
