Abstract
A paper straw for drinks is revealed. The paper straw includes a base material formed by a paper strip made from calcium carbonate. The base material is wound around an axis of a roller shaft obliquely and overlapped to form a hollow spiral tube whose two ends are communicated. Overlapped portions one over the other on the base material of the spiral tube are tightly connected. The paper straw that is environmentally sustainable, degradable and convenient to use can replace the plastic straw. The paper straw has premium quality and high performance.
