Latest company news about What is PET Clamshell?

A PET clamshell is a type of packaging made from Polyethylene Terephthalate (PET) plastic, designed in a hinged "clamshell" shape that opens and closes like a clam. It is commonly used for retail packaging due to its durability, transparency, and ability to securely display and protect products.

Key Features of PET Clamshell Packaging:

  1. Material – Made from PET plastic, which is lightweight, shatter-resistant, and recyclable (#1 plastic resin code).

  2. Design – Two hinged halves that snap shut, often with a locking mechanism or heat-sealed edges.

  3. Transparency – Clear PET allows products to be visible, reducing the need for additional marketing materials.

  4. Security – Tamper-resistant design helps prevent theft (often used for electronics, cosmetics, and small consumer goods).

  5. Customizability – Can be molded into various shapes and sizes, with options for branding, printing, or adding inserts.

Common Uses:

  • Electronics (USB drives, headphones, batteries)

  • Toys and small gadgets

  • Cosmetics and personal care items

  • Food (berries, salads, bakery items in vented clamshells)

  • Pharmaceuticals and medical devices

Advantages:

✔ Lightweight yet durable
✔ Excellent product visibility
✔ Tamper-resistant and secure
✔ Recyclable (check local recycling guidelines)

Disadvantages:

✖ Can be difficult to open without tools (leading to "wrap rage")
✖ Some environmental concerns if not recycled properly

PET clamshells are popular in retail due to their protective and display-friendly properties, though some brands are shifting to more sustainable alternatives like rPET (recycled PET) or compostable materials.
