PET is widely used for which packaging item?

Deli and baking trays.

PET packaging takes advantage of its clear, rigid, and lightweight nature, combined with a good moisture and gas barrier and safe food-contact properties. These traits make it ideal for forming into trays that display food clearly while protecting it during handling and storage. Because of this, PET is widely used for deli and baking trays. Other materials like wood, metal, or ceramic don't share these plastic packaging properties, so they aren’t typical PET packaging items.

Wooden cutting boards.

Metal pipes.

Ceramic tiles.
