Introduction to Polylactic acid (PLA) card
Introduction to Polylactic acid (PLA) card

The development of smart cards such as bank cards, traffic cards, and social security cards has promoted the improvement of social informatization and brought convenience to people's lives. The main material of these cards is PVC resin. Due to the metal contained inside, it is difficult to recycle, and they are basically discarded, causing a lot of pollution. Therefore, the environmental problems caused by smart cards have become a difficult problem that the industry needs to solve urgently. 

Polylactic acid (PLA) is a novel bio-based and biodegradable material made from starch raw materials derived from renewable plant resources such as corn. The starch raw material is saccharified to obtain glucose, and then fermented by glucose and certain strains to produce high-purity lactic acid, and then synthesize polylactic acid with a certain molecular weight by chemical synthesis. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature under specific conditions, and finally produces carbon dioxide and water without polluting the environment. This is beneficial to protecting the environment and is recognized as an environmentally friendly material.

PLA corn material has the following advantages:

1. Products made of PLA card base materials are 100% biodegradable, and the degradation rate can reach more than 90% under 180 days of industrial composting.

2. The whole life cycle is 100% recyclable and reused.

3. Energy saving and carbon reduction, carbon dioxide emissions can be reduced by 60%, and non-renewable energy consumption can be reduced by 50%.

4. Low VOC, no formaldehyde, benzene, toluene and other toxic and harmful gas emissions from the material matrix.

PLA is biodegradable, so it is a better choice to replace PVC for making smart cards.
