Is there a difference between ordinary PP straw extruder and PLA straw extruder?

There are differences. Compared with ordinary PP straws, the production of pla straws requires higher equipment performance. Due to the particularity of PLA straw, it needs to be fully and uniformly plasticized at low temperature. The internal structure and length-diameter ratio of the common PP straw extruder screw can not meet the plasticizing conditions of PLA straw. When using ordinary PP straws to produce PLA straws, the PLA straws produced will have problems such as burrs and ripples on the surface.

Only the extruder specializing in the production of PLA straw can ensure the stable production of PLA straw.

Compared with ordinary pp straw extruder, PLA straw extruder can be said to be an upgraded version, and both ordinary pp straw and PLA straw can be produced.

If you need to produce pla straw or both, choose PLA straw extruder. The manufacturer of PLA straw extruder I know is Nanjing Maiou Machinery. They have a Baidu account and can read some articles about buying straw extruders. I hope it helps you!
