Material Information

PET

Polyethylene terephthalate, also known as PET, PETE, or PETP, is a thermoplastic resin of the polyester family. It is a widely used plastic in the making of food and beverage containers. Its popularity is originated from its high clarity and durability. In the use of disposable plastic cups, the clarity of PET cups are unmatched by other commonly used materials such as PP and PS.  

PET cold cups are not only freeze/heat resistant (-22° F to 180° F), but also crack resistant. Their durability makes PET cups the most popular disposable plastic cups on the market. PET cups are used for a wide range of products such as ice tea, slush, juice, ice cream, cold beer and more.  

PET is also known for its ability to maintain product integrity. It is odor free and able to maintain the original flavor and aroma of food and beverage. It has also replaced PVC in the use of food containers as PET offers a high degree of sterilization. 

Unlike other plastics, PET is fully recyclable. Its polymer chain could be recovered for additional use. Its resin identification code is 1. 

PP

Compare to Polyethylene Terephthalate, Polypropylene (PP) has a lower degree of clarity. Like PET, PP is a durable and tough material, and is resistant to heat, chemicals, and oil. In applying to the beverage packaging, PP cup (also known as translucent cup) is semi-transparent in color.  

CupDepot.com's PP cup is, however thinner and therefore enjoys a higher degree of clarity than average translucent cups.

PP is not fully recyclable like PET. Its resin identification code is 5.
