(PLA) Polylactic acid is a resin made from crops with high starch content such as corn and potato. PLA is biodegradable and fully compostable. It uses 65% less energy to produce than conventional oil-based plastics and generates 68% fewer greenhouse gasses and contains no toxins.
Features of PLA(POLYLACTIC ACID)
1.sufficient source of raw materials
Conventional plastics are made from petroleum, whereas PLA is derived from renewable material such as corn, and thus preserves the global resources, such as petroleum, woods etc. It's strategically significant to modern China which rapidly demands resource especially petroleum.
2.Low energy consumption
During production process of PLA, the energy consumption is as low as 20-50% of petroleum-based plastics(PE, PP etc.)
3.100% biodegradable and Eco-friendly
The main character of PLA is 100 biodegradable which will be decomposed into carbon dioxide and water under certain temperature and humidity. The decomposed substance is sompostable which facilitates plant growth.
4.Excellent physical properties.
Melting point of PLA is the highest among all kinds of biodegradable polymer. It possesses high crystallinity, transparency and can be processed through injection and thermoforming.
Application of PLA(POLYLACTIC ACID)
Applying biodegradable and compostable PLA in various products manufacturing is the best way to resolve the global problem of environmental condition degradation.
PLA has the same chemical properties as other petroleum-based plastics and hence can be widely applied in industrial, agricultural as well as medical spheres. It can be used for manufacturing of diversified products from disposable cutlery to packaging products.
Comparison between PLA(POLYLACTIC ACID) and petroleum- based Plastic
