PET (Polyethylene Terephthalate) cups are eco-friendly, durable, and versatile beverage containers. Made from recyclable plastic, PET cups help businesses showcase their commitment to sustainability. PET cups are ideal for cold beverages, resisting condensation, and maintaining the chill of drinks.

They come in different sizes, colors and styles. Some have lids and straws, while others are clear or opaque. Many are lined with a wax coating to prevent leaks. The most common types of disposable plastic cups type are made from PET, or polyethylene terephthalate, as PET cups are durable and long-lasting.

Takeaway paper cups are lined with a polymer (plastic) lining to make them waterproof. Traditionally this lining is polyethylene, but in the case of compostable cups it is a polylactic acid plastic lining. The plastic lining in takeaway coffee cups is just one element making these difficult to recycle.

“Reusable” cups aren't necessarily much better when it comes to leaching, as they are often made of plastic; heat and wear accelerates leaching, and acidic drinks like coffee absorb chemicals more easily.
