Processability of modified fibres for complex shaped parts

There is a drive towards the use of single-component materials in different applications, for example in opening and closure of packaging products and in single use plastics (SUP). This opens up the possible use of cellulose-based products, but increases the demand for new modification strategies for fibres. Modifications aiming at improving their processability and final

Towards zero defects in packaging materials

Modern produktutveckling är till allt större del virtuell vilket innebär att datormodeller används för att förutspå en förpacknings beteende innan den existerar fysiskt. Fördelen med att använda datormodeller är att produktutvecklarna kan pröva nya ideer och koncept virtuellt utan att tillverka dyra fysiska verktyg samt att ledtiden från ide till produkt kan kortas avsevärt. Vidare

Scale-up of sustainable production of dialdehyde cellulose and dialcohol cellulose

The project is a collaboration between Chalmers, KTH, BillerudKorsnäs and TetraPak.  The aim of the project is to develop a closed or semi-closed techno-economical feasible process for production of Dialdehyde cellulose, DAC and its derivatives with a target to replace plastic materials in different applications such as thermoforming, extrusion and moulding.  The project will have

4D characterisation of paperboard mechanics

The project involves the development of new experimental methods to characterize deformation processes in fiber-based materials, in particular paperboard. The experiments are to be performed on several scales, from micro to macro, and aim to increase understanding of the mechanisms that control the mechanical properties and behaviour of the material. Experimental devices that can be

Constitutive modeling for macro-micro delamination for paperboard/Tow ards zero defects in packaging technology

The project aims to develop experimental methods for characterizing packaging materials. In the project, the microstructure of packaging materials w ill be methodically characterized and linked to mechanical properties. Traditionally, mechanical testing of paperboard material has been carried out without regard to micro-level mechanisms. With new experimental methods such as in situ x-ray tomography, much

Design av fuktokänsliga biobaserade syrgasbarriärer genom att systemtiskt korrelera biopolymernas molekylstrukturna till barriärfunktionen

The total Swedish export income from packaging and forest-based products is more than 11%. Our forest is a renewable resource that can be used to produce and develop more sustainable packaging materials with decreased climate stress compared to today’s fossil ones or aluminum foil. But, the replacement of fossil based materials with bio-based counterparts is
