Project summary
The goal of the project is to develop new, multifunctional biopolymer-based packaging systems, and design their controlled manufacturing technology. In the project we will do a wide range of basic research (e.g. softening, increasing thermal stability, strengthening) to modify the properties of polylactic acid (PLA) in order to make them easier to adjust flexibly and controllably according to the requirements (e.g. distribution of molecular weight, crystallinity, processing window, strength, stiffness etc.) of innovative packaging applications. We plan to make multifunctional packaging materials from the developed biopolymer types, first making sheets, then performing thermoforming and foaming.
Project results
Section 1
1 January 2017 - 30 June 2018
We found from our extensive laboratory and industrial experiments that the glass transition temperatures and the cold crystallization and crystalline melting maximum temperatures of the examined polylactide (PLA) samples decreased as a result of the addition of the lactic acid oligomer (Fig. 1). We performed successful hot forming experiments and found that the processing window somewhat narrows as a result of the lactic acid oligomer but forming temperature becomes lower and the ductility of the material increases, which facilitates hot forming. Cyclic fatigue tests showed that the oligomer content considerably improves the toughness of the hot-formed product. We showed that the nucleating agents added to PLA significantly increase the heat deflection temperature of subsequently heat-treated specimens—from ~55 °C to 140 °C. We also proved that the ball fracturing test can be successfuly used to grade sheet/film-based preforms and a relationship can be found between these results and hot forming technological parameters. Using the experimental thermoforming process, we graded hinges, etc. and manufacturing technology parameters with prototype molds. With our industrial sheet manufacturing experiments we identified manufacturing technology parameters. We produced low-density microcell PLA foams by chemically and physically foaming the reference PLAs of different D-lactide content. We showed that during foaming the composition of the extrudate and the density of the foam can be followed and graded by Raman spectrometry. We also showed that flame-retarded PLA foams can be produced by adding functionalized additives, and in the UL-94 test, the best, V-0 (self-extinguishing) grade can be achieved. The compression strength of the manufactured flame-retarded PLA foams is comparable to the EPS-100 type foams.
