How Cereplast Bioplastic Resins are Made
Bioplastics manufacturing begins once the appropriate polymer matrix is selected. The polymer matrix may be a biopolymer such as polylactic acid (NatureWorks Ingeo® PLA), PHA or PBS or other resin such as PBAT, polypropylene (PP) or thermoplastic elastomer (TPE). Other blend components can include fillers (e.g., calcium carbonate, talc or gypsum), starch (e.g., from corn, rice or potato) or additives (e.g., UV and thermal stabilizers, lubricants and compatibilizers).
The blended components are then dispersively and distributively mixed together using proprietary Cereplast processing equipment and knowhow. The resultant bioplastic is then prepared for use by a customer in traditional plastics processing equipment, including injection molders and sheet, profile and blown film extruders.
Cereplast bioplastics are packaged in the appropriate materials for maintaining the proper moisture content in the resin, eliminating the need for drying by many customers.
