Granules are in light white and come in cylinder and round shape, with
slight fragrance. They absorb moisture easily and are easily decomposed by
microbes. They are anti-static. The processing temperature of them is
lower than that of conventional plastic. They are easily colored. Such
resin can be processed alone into finish products without adding any other
All kinds of injection molded products, like tableware, food tray, plates,
drinking cups, plant nursery pots, disposable tableware, etc.

Newly molded products feel crispy and fragile due to severe dehydration
during production. After 24 hours of curing time, molded properties and
hardness will increase obviously.
It also can
be mixed with PP, including T30S, F401, J340, B240, K8303, X30S, etc.
Due to the high starch content, the resin easily absorbs moisture. So it
needs to be stored in a dry environment. The package should also be sealed
properly to prevent the ingress of moisture.
In case the resin is damp, it should be dried for 2 hours at 80ºC.
Its processing temperature is 5ºC to 10ºC lower than that of PP. During
processing, the temperature is correct when corn starch fragrance can be
smelled at the hopper.
It can be easily decomposed into soil friendly substances in microbial
