Biodegradable Plastic

Biodegradable Plastic

The main target markets for biodegradable plastic are plastic packaging film, agricultural film, disposable plastic bags and disposable plastic tableware.

Colour masterbatch

Colour Masterbatch

The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by super-constant pigment uniformly attached to the resin, which can be called pigment concentration.

Engineering Plastic

Engineering Plastic

Compared with general plastics, engineering plastics can meet higher requirements in mechanical properties, durability, corrosion resistance, heat resistance and other aspects, and it is more convenient to process and can replace metal materials.


Filler Masterbatch

Filling masterbatch can be used to process plastic films, garbage bags, shopping bags, vest bags, packaging bags, etc. It has good dispersibility, blown film has no white spots and black spots, high fineness to guarantees product gloss and toughness.
