New Blow Moulding Materials
Bio-Based Plastics: PLA & PHA
Bio-based plastics, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHA), are leading the trends in blow molding materials for 2025. These materials come from renewable resources and offer a sustainable alternative to traditional plastics. PLA and PHA can be processed using several methods, making them versatile for different applications. The table below shows common processing methods for these bio-based polymers:
| Processing Method | Description |
|---|---|
| Extrusion | Used globally to create films, sheets, and profiles. Most PLA and starch blends work with standard extruders. |
| Injection Molding | Enables production of durable goods and cutlery. Widely adopted for Bio-PE and some PBAT blends. |
| Blow Molding | Ideal for bottles, packaging, and trays. |
| Advanced Technologies | Synthetic biology, metabolic engineering, biofoundries, fermentation, and advanced recycling methods enhance production and sustainability of PLA and PHA. |
PLA offers a tensile strength of about 54 MPa, which is similar to PET, and a tensile modulus of 3.4 GPa, slightly higher than PET. PLA’s molecular weight influences its mechanical properties, with higher molecular weight leading to increased strength and stiffness. PLA has a low melting point, making it easy to process but less suitable for high-temperature uses. Both PLA and PHA degrade in the environment through hydrolysis and microbial action. PHA is biodegradable into carbon dioxide and water and is non-toxic to soil and air. These features make bio-based plastics attractive for manufacturers seeking sustainable blow molding solutions.
