Biodegradable PLA Cosmetic bottle!

Nowadays, with the enhancement of people’s awareness of environmental protection, more and more clients requires natural plastic material cosmetic packaging, the PLA plastic packaging meets the trends of global environment protection, which will help you attract more customers.

What’s PLA?

Polylactic acid (PLA) is a novel biobased and renewable biodegradable material made from starch raw materials proposed by renewable plant resources such as corn and cassava.

How is PLA made?

The starch raw material is obtained by saccharification to obtain glucose, and then glucose and a certain strain are fermented to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis.

Polylactic acid has good thermal stability, processing temperature of 170-230 ° C, good solvent resistance, and can be processed in various ways, such as extrusion, spinning, bi-axial stretching, and injection blow molding.

What are the Characteristics of Polylactic Acid?

It has good biodegradability. After being used, it can be completely degraded by microorganisms in nature under certain conditions, and eventually produces carbon dioxide and water without polluting the environment. This is very beneficial to the environment and is recognized as an environmentally friendly material.

In addition to biodegradability, products made of polylactic acid have good biocompatibility, gloss, transparency, hard and heat resistance, and also have certain bacteria resistance, flame retardancy and UV resistance. It’s widely used as packaging materials, fibers and nonwovens etc. Currently, it is mainly used in clothing (underwear, outerwear), industry (construction, agriculture, forestry, papermaking) and medical and health fields.

What is the difference between  PLA and normal plastic?

PLA is classified as a “thermoplastic” polyester (as opposed to “thermoset”), and the name concerns the way the plastic responds to heat. Thermoplastic materials become liquid when meeting their melting point. A major attribute of thermoplastics is that they can be heated to their melting point, cooled, and reheated again without significant degradation. Instead of burning, thermoplastics like Polylactic Acid liquefy, which allows them to be easily injection molded and then subsequently recycled. By contrast, thermoset plastics can only be heated once (mainly during the injection molding process). The first heating causes thermoset materials to set (similar to a 2-part epoxy) ,causing a chemical change which cannot be reversed. If you try to heat thermoset plastic with a high temperature a second time , then it would burn easily . This characteristic makes thermoset materials poor at recycling.

Is PLA toxic?

NO when it appears in solid form. In fact, Polylactic Acid (PLA) is biodegradable. It is often used in food handling and medical implants, with time it will biodegrade inside the body.

What are the Disadvantages of Polylactic Acid?

PLA has a relative low glass transition temperature, which makes it quite unstable for high temperature applications. Even the car in summer would causes it to soften and deform.
