What is PE?
PE lining in paper cups refers to a thin layer of polyethylene (PE), a type of plastic, that is coated on the inside of the cup. This lining serves two main purposes:
Waterproofing: It makes the paper cup waterproof, so it can hold liquids like coffee or tea without leaking or soaking through the paper.
Durability: It strengthens the cup and helps it maintain its shape when filled with hot or cold beverages.
In simple terms, PE lining is the plastic coating inside a paper cup that prevents it from getting soggy or leaking when used for drinks.
