Cup Stock – PE Coated Boards
The paper used to make a paper cup, referred to as a stroke of paper cup, is a PE paper type. There is a thin layer of polyethylene on the inside of the paper to prevent leakage of water into the cups.
Polyethylene coated cardboard is used to produce cardboard disposable containers (cardboard molds, cardboard plates, etc.), and they are also referred to as "PE Coated" cardboard, one-side or two-side, used to produce PaperCup paper cup.
