Project

Food Contact Thin Walled Injection Moulded All PLA Packaging

This project focuses on the introduction of a bio-based PLA compostable thin-walled plastic on packaging products, having an impact on the carbon footprint and circularity of these type of products.

Motivation

Thin-walled plastic packaging products are important for the logistics and preservation of our daily-used food products. The combination of lightweight and superior barrier properties make them a crucial link in CO2 reduction activities and prevention of food waste. Currently used petroleum-based polymers are not a circular solution since they cannot be recycled into food-safe packaging, however, the introduction of a bio-based compostable plastic alternative can provide an advantage in this respect. Poly(lactic acid)(PLA) provides a combination of transparency and outstanding mechanical performance together with its commercial availability and accessible price.

Aim & Expected Results

The goal of this project is the development of high flow (if possible additive-free) PLA compounds & products thereof suitable for food contact applications. The developed PLA compounds or PLA architectures can be used in the production of thin-walled food packaging via injection moulding. The intended results of the project are new functional bio-based packaging products that reduce food waste by protecting the product but also increase adequate waste collection by introducing in the market compostable food packaging materials that can be disposed of together with the food waste (if necessary). The use of bio-based packaging contributes to the reduction of CO2 emissions by substituting fossil raw materials by renewable alternatives.
