How to ensure that PLA eco-friendly cards can be completely degraded in the natural environment?
Use high-purity, reliable quality PLA materials. At the same time, choose PLA with a moderate molecular weight. Too high a molecular weight will slow down the degradation rate, while too low a molecular weight may affect the physical properties of the card.
The degradation of PLA eco-friendly cards requires appropriate temperature and humidity conditions.Generally speaking, an environment with a temperature of 50-60°C and a relative humidity of about 60%-80% is conducive to the growth and metabolism of microorganisms, which can accelerate the degradation of PLA. In a natural environment, the cards can be placed in warm and moist soil, such as a composting environment, to simulate ideal degradation conditions.
