   Abstract : In packaging industries, the demand for usage of Low Density Poly Ethylene foil is of profound interest. In the past, research was carried out on finite and infinite plates with varying crack lengths but having constant crack width. In this thesis, a detailed analysis on crack initiation is carried out on finite plates by varying width of the hole. READ MORE

5. 24. Enhanced dielectric AC breakdown strength of polyethylene using voltage stabilizing additives

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Klas Esbo; [2016]
   Keywords : cross-linked polyethylene; LDPE; low density polyethylene; polyethylene; voltage stabilizing additives; fast avalanche breakdown; dielectrical breakdown strength; High voltage cable; HVAC; XLPE; Weibull distribution; AC breakdown; materials chemistry; materialkemi; Technology and Engineering; Chemistry;

   Abstract : There is currently a need to increase the voltage level in high voltage transmission and distribution systems in order to transmit power in a more efficient way. However, the insulation of the conductor in high voltage alternating current (HVAC) cables needs to be improved in order to withstand these high voltages. READ MORE

6. 25. The Influence of Carboxylic Acid in Packaging Materials

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Jonas Mattisson; [2016]
   Keywords : food packing; Packaging Material; Carboxylic Acid; delamination; adhesion; polymer technology; polymerteknologi; Technology and Engineering;

   Abstract : Tetra Pak delivers food packing services world-wide and uses multilayer packaging materials to protect the food product from being affected by the environment. Loss of adhesion between the polymer and the aluminium layer in Tetra Paks packaging materials has proven to be a serious problem casing the package to lose its integrity and the food product to spoil.
