Features of PLA (Polylactic Acid)

1.Sufficient source of raw materials
Conventional plastics are madefrom petroleum, whereas PLA is derived from renewable material such as corn,and thus preserves the global resources, such as petroleum, woods etc.

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 is100% biodegradable which will be decomposed into carbon dioxide and water under certain temperature and humidity. The decomposed substance is compostable 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.

FAQ of PLA (Polylactic Acid)

1. Why PLA is also called "Corn plastic"?

PLA is derived from natural, renewable starchrich crop such as corn, potato.

2. Howdoes PLA decompose?

Under compost condition PLA will decompose into lactic acid when polymers are broken down. Lactic acid will decompose into water and carbon dioxide by bacteria.

3. How long does it take for PLA to decompose?

It will take 90-180 days under compost condition according to different sizes and thickness of the products.

4. What is PLA compost condition?

Compost condition refers to the co-existence of three key elements:

1). High temperature (58-70ºC)

2). High humidity

3). Bacteria co-exist

5. Will PLA products start decompose under normal temperature?

No, it will not. Same as the petroleum-based plastic products, PLA products can be used under normal condition. However, as PLA is not heat-resistant, it is recommended to be used under the temperature of 50ºC.

6. Any special precaution for PLA storage and delivery

1). Storage: Dry, ventilated and cool environment with optimal temperature 5~35℃.

2). Delivery: Prevent from direct sunshine and pressing, use strong carton box, control temperature during container load byapplying insulated materials.

7. Can our existing machine and molds for petroleum-based plastic products produce PLA products?

Yes. Machine and molds for petroleum-based plastic products can produce PLA products by adjusting the mold temperature and relevant production techniques as per the characteristics of PLA.

8. Which areas shall we pay attention to during the production of PLA products?

1). Temperature

2). Pressure

3). Moisture content of the material
