AI Technical Summary
Technical Problem
Polylactic acid resin has limitations in heat resistance, toughness, and gas barrier properties in food packaging, which restricts its application in high-temperature processing and long-term preservation scenarios.
Method used
A polylactic acid product with a microfiber structure is formed by using a combination of low-melting-point polylactic acid and high-melting-point polylactic acid, adding stereopolylactic acid and polyhydroxy fatty acids, and then extruding and molding the mixture after melt blending.
Benefits of technology
It improves the heat resistance and gas barrier properties of polylactic acid products, making them suitable for food packaging, especially coffee capsule packaging, ensuring food shelf life and environmental friendliness.
