The other day,looking for the plastic that suits best our future product, I discovered polylactictic plastic. A biodegradable plastic than is delivered from reneweble sources such as corn starch or sugarcane.
PLA, as it´s known, can be manufactured in many different ways: injection molding, sheet casting, among others.
It is useful for producing loose-fill packaging, compost bags, food packaging as well as a feedstock material in 3D printers.
Another interesting use it has is the medical implant one, it is used in this human medical implants because this bioplastic breaks down inside the body within 6 months to 2 years.
Going back to the life cycle analysis I was talking about in the last post, PLA can be recycled with no loss of original properties, that is to say it has cradle-to-cradle recycling.
If all this arguments where not enough, PLA can be colored, leading designers to choose between endless colors for their different products.
As every thing, not all is good neither bad and PLA has some disadvantages as well. The one than can affect more the products is it´s low glass transition temperature (60-65º).
Now that you are reading this, another person knows PLA, so what are you waiting for?
PLA is by far the best choice for today and for tomorrow.
