Biodegradable Materials

Bio-plastic Granule Resin

We supply different Biodegradable material for different applications, such as Additives of Bio-polymer, Materials of Extrusion Molding, Injection Molding, Blowing Molding and etc. We also help customers to design the formulation to meet their special requirement.


Transparent PLA Flexibilizer, Toughener, Anti Impact Agents

HZ-200 modifiers are outstanding impact modifiers designed to improve the performances of bio-polymers, such as Poly Lactic Acid (PLA). Targeted for use in the extrusion, thermoforming, blow molding and calendaring of Poly Lactic Acid (PLA) and other bio-polymers intended for food contact applications, HZ-200 impact modifier imparts toughness to PLA products while maintaining the clarity of the polymer.

Extrusion & Thermoforming Molding Grade

PLA for Extrusion & Thermoforming Molding grade is a thermoplastic resin designed for use in fresh food packaging and food service ware applications. It is a transparent general purpose extrusion grade that can be used naturally or as part of a formulated blend. This is a high molecular weight biopolymer grade that processes easily on conventional extrusion equipment. Extruded roll stock is readily thermoformable.
