How is Paper Cup Take-out Coffee Cup Made?
The takeaway coffee cup handed to you at a coffee shop may seem simple, but many people would be surprised to see how much thought and effort goes into making this "simple" paper cup safe and environmentally friendly.
Paper cup layer and lining
The outer layer of the cup, the wall, is made of cardboard. This layer provides thermal and insulating properties. It actually keeps the drink hot for as long as possible while not getting too hot and comfortable to carry around.
For cold drinks, a wall is enough. For hot drinks, it is best to use a double-walled cup for extra heat protection. In addition to insulation, a second sleeve covering the cup allows mixing and matching embossed patterns and prints to create a wide variety of designs.
The cardboard is lined with a thin plastic liner for safety reasons: it acts as a barrier to ensure food hygiene and makes the cup waterproof. Plastic is a suitable lining material because of its strength, resilience and excellent barrier properties. It is also good in materials, energy and cost efficiency.
For cups to be suitable for contact with food, cardboard or lining cannot currently be made from recycled materials. To reduce its carbon footprint, the plastic lining could be made from renewable plant materials, rather than fossil ones. Huhtamaki Future Smart, for example, is a cup made from 100% renewable materials.
