Specifications

Tensile strength

{'zh': '27.51', 'en': '27.51'} MPa

Advantages

Strength retained

Even with starch addition, the fiber-containing composite film maintains a tensile strength of 27.51 MPa, comparable to pure TSP film.

Soil biodegradable

The films exhibit favorable soil biodegradability and clean combustion behavior, preventing long-term pollution after disposal.

Applications

• Fruit preservation：The film's antibacterial and antioxidant properties reduce browning and microbial growth, extending shelf life.
• Biodegradable packaging：The film degrades in soil after disposal, replacing non-degradable petrochemical packaging films.
• Bio-based materials：Made from tamarind seed polysaccharide and other natural resources, reducing reliance on fossil fuels.
• Food packaging：Combining high strength and barrier properties, it can serve directly as food packaging liner.
