Products Description
What is PBAT Biopolymer?
PBAT is a synthetic biodegradable polymer derived from a combination of adipic acid, 1,4-butanediol, and terephthalic acid. It belongs to the family of polyesters, featuring a semi-crystalline structure with excellent mechanical properties and processability. Unlike conventional petroleum-based plastics, PBAT is designed to degrade under specific environmental conditions, breaking down into water, carbon dioxide, and biomass without leaving harmful microplastics behind.
Key Properties That Set PBAT Apart.
Advantages of PBAT Biopolymer
Exceptional Ductility
PBAT biopolymer stands out for its remarkable ductility, allowing it to be stretched into thin, flexible films without compromising structural integrity. This property makes it ideal for applications requiring high elongation, such as producing lightweight yet durable packaging materials. Whether used in shopping bags, agricultural films, or lamination layers, its ductile nature ensures products maintain form while resisting tearing during handling
Thermal Stability
With good heat resistance, PBAT can withstand moderate temperature ranges without losing its mechanical properties, making it suitable for applications that involve contact with warm contents-think food packaging for hot liquids or microwaveable containers. This thermal resilience also facilitates processing through common manufacturing techniques like extrusion and injection molding, ensuring compatibility with existing production lines.
Impact Resistance
PBAT's high impact resistance ensures it can absorb external forces without cracking or breaking, even at low temperatures. This characteristic is crucial for packaging applications where products need protection during transportation.
Products application
Diverse Applications of PBAT Biopolymer
1. Disposable Packaging: Redefining Single-Use Solutions
- Single-use supermarket films & bags: PBAT-based shopping bags and produce films provide a sustainable alternative to conventional polyethylene (PE) bags. They offer the same ease of use but with the added benefit of biodegradability, reducing reliance on fossil fuels and marine pollution.
- Plastic tableware (Plastic cutlery & tableware): From forks and spoons to cups and trays, PBAT-based tableware combines food safety with eco-friendliness. It meets global standards for contact with food while breaking down naturally at the end of its lifecycle.
2. E-Commerce & Logistics: Sustainable Shipping Solutions
In the booming e-commerce sector, express packaging accounts for massive plastic waste. PBAT-based bubble wraps, envelopes, and cushioning materials offer the same protective performance as traditional plastics but with a lower environmental footprint. Their biodegradable nature aligns with corporate sustainability goals and appeals to eco-conscious consumers.
3. Agriculture: Enhancing Crop Production Responsibly
- Agricultural mulch films: Traditional plastic mulches improve crop yields but contribute to soil pollution when left uncollected. PBAT mulch films degrade naturally after the growing season, eliminating the need for labor-intensive removal and reducing long-term soil contamination.
- Fertilizer & pesticide packaging: PBAT-based sachets and containers for agricultural chemicals ensure safe storage while minimizing environmental impact through biodegradation.
