AINIA and AIMPLAS investigate how to improve the properties of bioplastics packaging for food and beverage

This project follows the both center colaborative line to investigate innovation in biodegradable materials, given its potential for food and plastic containers

Valencia, October 18th 2016.- AINIA and AIMPLAS are working together in the SOSTPACK Project whose main objective is to improve the properties of biodegradable materials (biopolymers, also known as bioplastics) to facilitate their incorporation into food an beverage packaging market.

Global production of plastics is increasing in the last 50 years, only in 2013 was 290 million tons, of which 74% are polyolefins (petroleum-based plastics) of different types. However, only 0.2% of world production corresponds to biodegradable bioplastics.

Although there are different types of biodegradable bioplastics in the market and various applications for food packaging, these have not had the expected implementation in food, mainly due to the few commercial grades available in the market that cannot cover the properties required in each type of package and higher cost.

AINIA and AIMPLAS are working on the development of new formulations for biodegradable materials (bioplastics) to meet the greater number of needs in food packaging. To do this, it is necessary to  maintain the shelf life of food content and retain their organoleptic and nutritional characteristics. All with highest sustainability criteria.


Improved barrier properties

The SOSTPACK Project, which started in 2016 and lasts 24 months, includes interesting tests aimed to investigate the barrier to oxygen and heat resistance of biodegradable materials, that are marketed today, including structural improvements of these materials, in order to be processed in conventional industrial equipments.

The development of these new formulations will allow a large number of applications with these materials in the field of food packaging. In addition, there is also interesting in other potential sectors such as the plastics industry packaging for non-food use, such as customized consumer goods.


Innovation based on the combination of technologies

The novelty of this project, in contrast to other lines of R & D, lies in modifying the properties of bioplastics without incorporate additives. Modifying, chemically or physically, the structures of commercial biodegradable materials.

Therefore, it is working from the combination of various technologies. On the one hand, modification of bioplastics by chemical means (reactive extrusion process in which changes to morphological and structural level) and physical (mixture of one or more polymers with other substances, which cause changes in physical properties of the material without linkages between the chains forming the biopolymer are modified).

Also we are using  predictive models and studies to simulate the shelf life of a food packaged in a  biodegradable material.
