1. Eco-friendly materials : Many straws are now made of PLA (polylactic acid) material, which is derived from cornstarch or sugar cane and is more environmentally friendly than traditional plastics ¹ However, PLA straws require specific degradation conditions and cannot be discarded at will.

2. Multi-functional design : For example, the recently popular "three quality control" consists of three thin straws, which can better taste the aroma and layer of tea drink. This design can not only slow down the flow of tea, but also increase the aroma and make the drink better.

3. Health and safety : Glass straws and stainless steel straws have become the first choice of many health enthusiasts because they have no odor and do not contain harmful substances. Glass straws are transparent and easy to clean, while stainless steel straws are strong and durable .

4. Creative design : Some straws are made of edible materials such as pasta, which is not only environmentally friendly, but also can be eaten directly after use. This creative design is not only fun, but also reduces waste.

5. User experience : Different materials and designs of straws can provide different drinking experiences. For example, silicone straws are soft and flexible, suitable for people who like to bite straws ¹; Although paper straws are environmentally friendly, they are easy to get soft and affect the use experience.
