  PLA is the talk of the sustainable packaging town. And for good reason, it’s a bioplastic made from renewable, plant-based materials like corn, cassava and sugarcane. This article will dive into PLA bioplastic, how it’s made, the environmental benefits and how it fits into the circular economy.   What is PLA Bioplastic? Polylactic acid , commonly known as PLA, is a type of polyester derived from renewable biomass, often sourced from fermented plant starch such as corn, cassava, sugarcane, or sugar beet pulp. Although the current feedstock does not pose competition with food production, ongoing research is exploring the utilization of non-agricultural sources.   PLA bioplastics  offer substantial and measurable environmental and economic benefits compared to traditional plastics.     How is PLA Made? Let's delve into the technical details. PLA, a polyester containing the ester group, is formed using two potential monomers or 'building blocks': lactic acid ...

  You might be familiar with PLA, but what sets TPLA and CPLA apart? These two iterations of PLA products offer distinct advantages in the realm of eco-friendly packaging. What is TPLA and CPLA? To grasp the distinctions between CPLA and TPLA, a basic understanding of PLA, or polylactic acid, is necessary.   PLA products serve as bio-based and biodegradable substitutes for petroleum-based plastics. Typically derived from fermentable sugars, such as corn, PLA offers an environmentally friendly alternative to traditional petroleum-based plastics.   PLA stands as a comparable and environmentally friendly substitute for traditional plastics. However, due to its composition from corn rather than oil-based materials, it may exhibit lower rigidity and heat resistance compared to conventional plastics, which come in various numbered types tailored for specific applications.   To address these limitations, CPLA and TPLA were developed. These two ...
