PETG Blister Insert

Key Features:

Similar to PET blister plastic, Glycol-modified PET blister plastic is a transparent and highly recyclable material. PETG has a softer feel, is far less brittle, and has excellent heat and electric insulation, making it a popular choice for packaging food, pharmaceuticals, and electronics.

  • Lightweight and durable
  • Recyclable
  • Popular for packaging food and pharmaceutical products


Polyethylene Terephthalate Glycol (PETG) is a popular thermoplastic polyester that provides notable durability, formability and recyclability. PETG plastic is a form of PET plastic with added glycol. The chemical properties of PETG offer a smoother finish that is far less brittle than your traditional PET plastic box inserts. PETG plastic box inserts are easily vacuum-sealed, making them a popular choice for packaging food and pharmaceuticals. PETG's sturdy properties are well suited for processes such as die-cutting, routing, or bending into any custom shape.
