CJ Biomaterials introduces two PHA-based compounds for compostable film packaging

CJ Biomaterials introduced two PHA-based compounds – PHACT CA1270P (clear) and PHACT CA1240PF (opaque) – for blown, cast, and machine direction orientation (MDO) film applications.

CJ Biomaterials introduced two PHA-based compounds for blown film applications.

Outstanding performance for packaging

Both compounds demonstrated an outstanding balance between stiffness, strength, tear, and puncture resistance, ensuring durability in various packaging applications.

They have been successfully subjected to blown-MDO processing, achieving up to 4.0x stretch, and revealing orientation (birefringence) with improved puncture toughness, making them an optimal solution for oriented films for shrink wrap applications.

MDO films with CA1240PF result in microporous films, providing unique opportunities for various packaging applications.

The two grades also outperform LDPE/LLDPE blown films, providing greater modulus and strength. They also exhibit higher tear resistance compared to other biodegradable and compostable plastics.

More environmental benefits

CA1270P and CA1240PF are 100% biobased, providing a compostable alternative to traditional plastic films that enable food waste diversion away from landfill sites. They are both industrially compostable, with CA1240PF demonstrating the potential for home compostability, which tests are still ongoing.

The carbon footprint of both these new products are more than 50% lower than low-density polyethylene and linear-low-density polyethylene, polyethylene, polypropylene, and polyethylene terephthalate (LDPE/PE/PP/PET) solutions.

Versatile and wide applications

Both products have been qualified on industrial production lines by several large film converters.

They are suitable for a wide range of applications, including snack food and produce packaging, frozen food bags, shopping bags, shrink-wrap and labels, hygiene backing films, organic waste diversion bags and agricultural mulch films.
