What are clear plastic boxes made of?

November 03, 2023

Clear plastic boxes are typically made of a material called polyethylene terephthalate (PET), which is a thermoplastic polymer. PET is a strong and lightweight material that offers excellent transparency, making it ideal for manufacturing clear and see-through packaging.

PET is derived from petroleum-based sources and is known for its clarity, toughness, and resistance to impact. It is commonly used in the production of various packaging products, including clear plastic boxes, bottles, food containers, and blister packs.


During the manufacturing process, PET is melted and then extruded into thin sheets. These sheets are formed into the desired shape using techniques like vacuum forming or injection molding. Once the PET is molded into the shape of a box, it can be heat sealed, glued, or assembled in various ways to create a secure and functional packaging solution.


PET is widely chosen for clear plastic boxes due to its favorable properties, including excellent transparency, durability, moisture resistance, and good chemical resistance. Additionally, PET is recyclable, which makes it an environmentally friendly choice for packaging materials.


It's worth noting that while PET is commonly used for clear plastic boxes, there are other types of clear plastics as well, such as polystyrene (PS) and polyvinyl chloride (PVC). Each material has its own set of characteristics and applications, so the specific type of plastic used for clear boxes can vary depending on factors like cost, intended use, and desired properties.
