GreenTree Biodegradable Compostable Packaging Advantages

Performance Advantages

1. Extended Shelf Life – Low moisture absorption ensures a shelf life of over 1 year, significantly reducing the risk of premature degradation. In contrast, starch-based materials are prone to moisture hydrolysis and typically have a shelf life of less than 6 months.

2. Ultra-Thin Film Capability – Can produce films as thin as 8–10 microns. Starch-based materials are difficult to process below 12 microns, giving GreenTree a strong advantage in applications like thin mulch films.

3. Adjustable Transparency – Offers good clarity that can be customized to client requirements. Starch-based materials generally have poor transparency.

4. High Gloss Finish – Provides a premium, high-gloss appearance. Starch-based materials often appear dull and less visually appealing.

5. Superior Mechanical Strength – Higher load-bearing capacity at the same thickness, allowing for thinner and lighter packaging with equal strength.

6. Food Contact Safety – Complies with FDA and EU food contact regulations, making it suitable for direct food packaging after certification. Starch-based materials may experience significant plasticizer migration.

Material & Cost Advantages

1. Advanced Material Formulation – Uses a composite of PBAT + PLA + functional fillers. Starch-based materials typically rely on PBAT + starch + plasticizers, with starch content generally around only 20%.

2. Recyclable Production Waste – Trim waste and leftovers can be recovered and reused in production, increasing material utilization and boosting recycling rates by approximately 50%. Starch-based material waste is difficult to recycle and cannot be blended back.

3. Lower Processing Energy Consumption – Higher production efficiency, faster output, and over 20% lower energy consumption compared to starch-based materials, which require pre-drying and have slower, more energy-intensive processing.
