Conventional plastic drinking straws are typically made from thermoplastic resins such as polypropylene (PP). The process starts with small plastic pellets and turns them into a continuous hollow tube that is cooled, pulled through the production line, and cut into individual straws.

PLA straw deformation can show up in several ways. You may see a straw become oval instead of round, gradually change diameter, develop a wavy profile, lose straightness, or come out with weak walls and a rough surface.Temperature is often the first setting operators change,

A straw making machine is not one machine performing one job. It is a connected production system that prepares the raw material, converts it into a hollow tube, stabilizes that tube, moves it through the line, and cuts it into finished lengths.If you understand what each component does,

A high-speed straw making machine can increase production substantially, but speed alone does not tell you whether a machine is right for your factory.You also need to know whether it can maintain the straw dimensions and quality you require, how easily it handles product changes,

Commercial straw manufacturing starts with two decisions: what material you want to use and what the finished straw needs to look like.If you are working with materials such as PLA, PBAT, PHA, or PP, you will typically form the straw by heating the material and pushing it through a shaped die to create a continuous hollow tube, a process known as extrusion.
