EPI Addititives, your choice for a green packaging bag without adding much extra cost

Updated: Sep 6, 2021

The "EPI" technology is a chemical additive that speeds up the degradation process. First, they are degraded by heat, oxygen, sunlight, and mechanical stresses (like moving around or being pressed on by other trash). ... The "EPI" technology is a chemical additive that speeds up the degradation process.

TDPA™ is a family of masterbatches and those used for manufacturing single-use plastics are commercially known as DCP. TDPA™ is added to conventional plastic resins, primarily polyolefins such as PE and PP, in the manufacturing of oxo-biodegradable plastics. Plastics with TDPA™ exhibit properties similar to conventional plastics but they can degrade and ultimately biodegrade at the end of their useful life depending on the conditions of the surrounding environment.

EPI does not fabricate single-use plastics but sells TDPA™ to plastic manufacturers who make these products. The plastic products made using TDPA™ technology are called oxo-biodegradable plastics⁽¹⁾.


Controlled Life: Have a controlled life. The product life (shelf life and service life) can be customized ranging from a few months to a few years depending on its application.

Properties: Have similar physical and mechanical properties as conventional plastics prior to the onset of degradation.

Biodegradable: Degrade and biodegrade in the environment in the presence of oxygen and micro-organisms to carbon dioxide, water and biomass(2).

Processability: Manufactured using the same machinery and equipment as conventional plastics.

Cost: TDPA™ is cost effective because of its small addition rates, typically 1 to 2% depending on the product requirements.

Food Contact: TDPA™ is compliant with FDA (USA) and EFSA (EU) requirements for direct food contact applications.

Non-ecotoxic: Pass all ecotoxicity tests, including seed germination, plant growth and organism survival, in accordance with OECD standards.

Recyclable: Factory in-house scraps can be recycled with conventional plastics prior to the onset of degradation. Post-consumer TDPA™ plastics can also be recycled with conventional plastics in existing recycling stream if collected during their useful life, depending on the availability and policy of local recycling facilities.

Standards: Tested in accordance with oxo-biodegradable plastics standards ASTM D6954 and the equivalent norm BS8472.

Validation: The degradation, biodegradation and non-ecotoxicity of plastics made with TDPA™ are independently validated by third-party laboratories. TDPA™ oxo-biodegradation has also been studied and proven by scientists for more than 20 years.
