If you’ve read this guide thoroughly, you know that not all coffee cups tend to be same. Each one has a specific use and feature. And thus their making process differs too. For instance, the way the manufacturers make the plastic cups isn’t how they make the glass ones. Similarly, paper coffee cups have a different composition. They have four main components – a paper layer, a polyethene layer, a plastic top, and a paper sleeve. The construction of the coffee cup determines how the manufacturers have made it, strong and sturdy.
