PLA drinking straws manufacturing conditions may vary according to market and quality requirements as well as specific set up of plastics convertors or extruders. The manufacturing set up can be expected to be customized depending on machinery feed rates, cutting technology, cooling systems, texturizing, thickness and flexibility of the straws.
Since PLA is highly sensitive to moisture, drying conditions of neat PLA are extremely important and decisive to achieve a successful and stable process.
The use of «hot knives» is key to reduce cracking in straws as well as to eliminate jagged edges during cutting, providing smooth edges of straws.
