Compostable thermoplastic starch film for dairy packaging

Overview

The compostable thermoplastic starch (TPS) film is an innovative solution for dairy food packaging. Derived from natural starch, TPS is a sustainable alternative to traditional plastic films. It is designed to meet the flexibility and stiffness requirements of dairy packaging while being environmentally friendly. By incorporating antimicrobial agents such as essential oils or silver nanoparticles, this TPS film can significantly reduce microbial growth on dairy products, thereby extending their shelf life. The film is optimized for extrusion processes to enhance its mechanical properties and ensure effective antimicrobial distribution.

Technical specifications

Key features:

• Made from natural starch polymers, amylose and amylopectin, with added plasticizers and compatibilizers to improve flexibility and durability.
• Incorporates antimicrobial agents for controlled release, inhibiting bacteria, yeast, and mold growth.
• Optimized extrusion parameters improve tensile strength, elongation, and oxygen transmission rate (OTR).
• Designed for compostability and biodegradability, ensuring environmental safety.
• Suitable for various dairy packaging applications, maintaining product quality and safety standards.

Technology readiness level

The development of the TPS film is currently at Technology Readiness Level 2, indicating that the technology is at the formulation and lab-scale extrusion stage. Future steps include lab-scale trials, compliance testing, and real-world packaging trials to progress toward commercialization.
