What is PSM?

PSM (Plastarch Material) is an eco-friendly, bio-based plastic alternative made primarily from corn starch. Developed through advanced bio-polymer technology, PSM is engineered to mimic the strength and durability of petroleum-based plastic while offering a significantly reduced environmental footprint.

 

At its core, PSM is a thermoplastic material derived from natural, renewable resources. It is commonly used to manufacture biodegradable and compostable products such as disposable cutlery sets, food packaging containers, and catering supplies. For businesses aiming to reduce plastic waste and meet eco-conscious consumer demands, PSM presents a practical, sustainable solution.

 

 

The creation of PSM begins with corn starch, which undergoes a modified fermentation and polymerization process. During this process, the starch molecules are transformed into long-chain polymers. To improve its properties, natural additives and modifiers are blended into the material, resulting in different resin formulations such as the HL-100 and HL-300 series.

 

HL-100 Series: Contains a high percentage of corn starch. It's bio-based but not fully biodegradable. Ideal for applications where environmental benefits are desired without compromising performance.

 

HL-300 Series: Fully biodegradable and compostable. Meets EN13432 and ASTM D6400 standards, making it suitable for commercial composting systems.

 

 

PSM is gaining global popularity in the foodservice industry due to its excellent functional properties and environmental advantages:

1. Eco-Friendly and Renewable

Unlike traditional plastic made from petroleum, PSM is sourced from corn starch, a renewable agricultural resource. This makes it a carbon-reducing alternative that helps combat plastic pollution and conserve fossil fuels.

 

2. Biodegradable and Compostable

Especially the HL-300 grade of PSM, which breaks down into natural elements in commercial composting facilities. It's a safer option for landfills and marine environments, reducing long-term waste accumulation.

 

3. Heat-Resistant and Durable

PSM performs well under high temperatures, making it suitable for microwavable food containers and hot food cutlery. It holds shape and structure without melting or warping, offering a reliable user experience.

 

4. Versatile Manufacturing

PSM is compatible with various production processes such as injection molding, thermoforming, foaming, and film blowing. This flexibility allows manufacturers to produce everything from disposable forks and knives to biodegradable trays and bags.

 

5. Meets Global Composting Standards

Products made with compostable PSM resins can meet certifications including EN13432 (EU) and ASTM D6400 (USA). This ensures compliance with international sustainability regulations, important for exporters and global brands.
