Clamshell Packaging

Clamshell packaging is perfect for products intended to be positioned directly at the consumer. This type of plastic packaging offers better security than blister packaging, for example, and is a popular packaging choice for small high-value items. Clear, plastic clamshells are useful, high visibility, clean, protective and reusable packaging solutions for the retail, electronics, industrial, consumer goods and medical applications. Clamshells can be manufactured from a wide variety of resins based on the application or proposed function. Common clamshell materials incude PET, PVC, PS, PP, OPS, and PETG (read more about them). For sustainable solutions, recycled content and even bio-based materials are available.
