Straw

It was invented by Marvin Stone in the United States in 1888. In the 19th century, Americans liked to drink cold, light flavored liquor. In order to avoid the heat in their mouths reducing the freezing strength of the liquor, they did not drink it directly from their mouths, but instead drank it with hollow straw. However, the straw was easy to break, and its own flavor would also seep into the liquor. At that time, Marvin Stone, a cigarette manufacturer in the United States, inspired by cigarettes, created a paper straw. After trying it out, it neither broke nor had any strange taste. From then on, people not only..." When drinking light flavored liquor, I also like to use paper straws when drinking other cold drinks. After the invention of plastic, paper straws were replaced by colorful plastic straws because their flexibility and aesthetics were better than paper straws.

Straw making method: After melting the plastic, it is passed through an extrusion mold, which is the mouthpiece. Then, the machine extrudes the plastic like a syringe (this process is continuous, and there is a screw on the machine, which will extrude at a speed). When the plastic is still soft, it is sent into the machine, directly formed, and later cut by the machine, becoming the straw we see in sections.
