2. 1. Mechanical Behaviour of Adhesive Joints in Cartonboard for Packaging

   Author : Christer Korin; Magnus Lestelius; Nils Hallbäck; Christophe Barbier; Christer Fellers; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot melt Adhesives; Carton board; Y-peel; Peel strength; Chemical Engineering; Kemiteknik;

   Abstract : A cartonboard package is often sealed and closed with an adhesive – either a hot-melt adhesive (adhesives that are applied in a molten state on the cartonboard) or a dispersion adhesive (adhesives that are applied as water-based dispersions). This thesis focuses on the process of hot-melt gluing, and how material properties and process conditions affect the performance of the adhesive joint. READ MORE

4. 2. Protein-based Packaging Films, Sheets and Composites: Process Development and Functional Properties

   Author : Sung-Woo Cho; Mikael Hedenqvist; Amar K. Mohanty; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; wheat gluten; solution casting; compression molding; extrusion; injection molding; aging; migration; opacity; heat sealability; hemp fiber; laminate; polylactic acid; clay; nanocomposites.; Other chemical engineering; Övrig kemiteknik;

   Abstract : The depletion of the petroleum resources and a number of environmental concerns led to considerable research efforts in the field of biodegradable materials over the last few decades. Of the diverse range of biopolymers, wheat gluten (WG) stands out as an alternative to synthetic plastics in packaging applications due to its attractive combination of flexibility and strength, high gas barrier properties under low humidity conditions and renewability.

5. 3. Fracture Behaviour of adhesive Joints in carton board

   Author : Christer Korin; Gunnar Engström; Erik Serrano; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

   Abstract : A carton-board package is often sealed and closed with an adhesive. Package requirements vary depending on how the package is to be used. A package that is only supposed to protect the product during transport differs from one that is supposed to attract consumers and facilitate the use of the product by consumers. READ MORE

6. 4. Tailoring Adhesion and Wetting Properties of Cellulose Fibres and Model Surfaces Using Layer-by-Layer Technology

   Author : Emil Gustafsson; Lars Wågberg; Gero Decher; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : The versatile layer-by-layer (LbL) technique, for consecutive adsorption of polyelectrolytes and charged nanoparticles onto a substrate, was used to modify cellulose fibres and model surfaces for improved mechanical and wetting properties. In addition to being used to modify cellulose substrates, the LbL technique was also used to create cellulose surfaces suitable for high resolution adhesion measurements. READ MORE

7. 5. Effect of fruit flavors on anaerobic digestion : inhibitions and solutions

   Author : Rachma Wikandari; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fruit wastes; Fruit flavors; Anaerobic digestion; Biogas; Leaching pretreatment; Membrane bioreactors; Resource Recovery; Resursåtervinning; Resource Recovery; Resursåtervinning; Resource Recovery;

   Abstract : Fruits are among the most important commodities in global trading due to its fundamental nutritional values. In 2012, the fruits supply was 115 kg/person/year, however, only 50 % of the fruits reached their consumers and the rest ended up as waste during the long fruit supply chain. READ MORE
