A paper cup with a PE coating is a cup made of cardboard, which is covered with a polyethylene (PE) coating on the inside. The PE coating is a thin layer of polyethylene applied to the surface of the cardboard to prevent liquids, such as hot drinks, from seeping through the cardboard.

These cups are often used for serving hot drinks such as coffee, tea or soup. The cardboard exterior provides strength and insulation, while the PE coating prevents liquid from penetrating the cardboard and soaking the cup.

Using a PE coating on paper cups has benefits, such as reducing leakage and providing a heat barrier for retaining hot drinks. However, it is important to note that some PE coatings may not be biodegradable and therefore contribute to the waste problem.

However, in recent years, alternatives have also come onto the market, such as cups with a water-based coating. Paper2paper, the paper cups that are really made of paper and can be recycled together with paper.
