Soarus, LLC has introduced Nichigo G-Polymer™, a multifunctional, high-barrier, and water-soluble polymer. Properties of the new polymer include:
• Biodegradability
• Water solubility at room temperature
• Nonfoaming when dissolved in water
• An oxygen gas barrier that is said to be 200-times better than EVOH when dry
• High clarity
• Extrudability with a wide melt-temperature processing window
• Design flexibility to meet specific application needs
Nichigo G-Polymer is a high amorphous-content vinyl alcohol resin with a crystallinity that can be tailored down to the point of total amorphous character. According to the company, the polymer combines two typically traded-off functions; although it is an amorphous resin, it also has crystalline-like functions. Such combination functions are evidenced by the gas barrier properties and chemical resistance of the polymer, similar to PVOH and EVOH resins, along with water solubility and lower crystallinity.
The polymer is said to have superior extrusion properties, orientability, shrinkability, and transparency. It can be used in all extrusion processes and is particularly suited for oriented film, transparent containers, injection molding, and more. And, because the polymer is biocompostable, the company says it lends itself to a variety of applications, such as new packaging materials, that are environmentally friendly.

Is this for real? How quickly does it biodegrade? What does it need to biodegrade, lots of heat and moisture? Does it biodegrade into non-biodegradable components?
I would love to know. Plz email me.
Very interesting. How susceptible is it to hydrolysis? Will a hot and humid warehouse cause visible degradation?
I would like some more info as well. Please email me: wzhang@celplast.com
